With the continuous development of security monitoring technology, market demand for security monitoring also quickly changed intelligent video surveillance system for home security, anti-terrorism and security needs, user requirements are increasingly urgent, and therefore in recent years, smart of high-definition video surveillance system has become a clear development direction, which means that the requirements of the users of the monitoring system will be more focused on the surveillance camera image clarity, attention to the monitor screen in the extent to which the site consistent intelligent analysis system enabling it to be used to accurately identify abnormal target. Traditional analog cameras can not meet the demand for high-definition image capture, HD has become the mainstream of the development of today's video surveillance, to achieve high-definition video surveillance, can not be separated from the high-definition camera, therefore, megapixel ip camera products have emerged. Megapixels HD ip camera appear laid the foundation for for HD monitoring program realization megapixel ip camera is based on IP network transmission of high-definition camera. Constitute an example to introduce a general definition network cameras, front to back turn lens, infrared cut filter, the image sensor, clock synchronization motherboard, power supply, and I / O network interface board compression and image processing encoding. In all the constituent parts, the most critical is the image sensor, the indicators or a direct impact to the excellent high-definition network camera picture effect. Currently on the market, most of the high-definition network cameras using CMOS as the photosensitive element CCD sensor, HD ip camera advantages. Megapixels ip camera just a general term of high-definition network camera industry, refers million and more than one megapixel ip camera, but the industry has not yet formed a standard to define megapixels and HD. Megapixels is the effective number of pixels of the sensor used in network camera reaches more than one million, at the same time, this scene HD camcorder output screen resolution of at least 1280 × 720. The image resolution of today's mainstream 1.3-megapixel, 2.0 megapixel, 500 or higher megapixel megapixels grade network camera output are generally at least 720P (1280 × 720) or 1080P (1920 x 1080). From the current industry recognized standards, the video screen resolution of 720P HD is a basic requirement, and even on some occasions called quasi-HD, because the strict sense, the 1280 x 720 resolution has not yet reached a hundred million pixels. And is generally recognized as the true high-definition images, video screen resolution needed to reach 1920 × 1080, that commonly referred 1080P. Is easy to see from the above-mentioned video screen resolution megapixels HD ip camera video screen is the era of traditional analog cameras can not match the clarity improvement, enlargement of the image field of view, are the most prominent advantages. On the one hand, from the resolution numerical comparison, the screen resolution megapixels HD ip camera many times greater than the advantage of the traditional camera clarity; practical application in addition to the level of clarity of the video screen, there is a very important requirements that the real-time nature of the video screen to view the PAL transmission and playback frame rate of up to 25 frames / sec. Transmission and presentation of high frame rate currently the most megapixel ip camera on the market in 720P or 1080P resolution format can achieve 25 frames / sec, and reached the 2560 × 1920 resolution HD ip cameras are mostly not achieve such the clarity under real-time rendering. Practical application in the industry, customers tend to have very specific monitoring requirements, as well as to achieve the objectives and requirements. Such as bank teller monitoring system needs to be able to clearly see the facial features of every coming for business personnel; traffic road monitoring need to be able to clearly see the license plate number of the vehicle by each lane. Traditional non-high-definition monitor, in order to meet these special needs often require for each teller, each individual lane cameras installed to narrow the monitoring vision and clarity to ensure that monitoring goals. Megapixels HD ip camera application, you can use the one megapixel ip camera instead of multiple non-high-definition camera, and can reach the need to use multiple traditional cameras in order to achieve the monitoring results. Three-lane road monitoring format cameras use SD D1 resolution monitor For a clear license plate information, you need to be installed separately for each lane cameras require a total of three cameras to the lanes completely monitoring. Megapixels HD ip camera, you can achieve a camera monitoring of the three-lane, and get a clear license plate information. Megapixels HD ip camera, there is no doubt to the majority of users has brought great convenience, but also makes security monitoring quality has been greatly improved to accelerate the exit of existing markets, while also continue to promote traditional analog cameras. So if you want to select in the practical application of the higher pixel camera monitoring the effect of the greater good? In fact, megapixels HD of course bring to enhance the quality of the screen, but at the same time should also see that the increase in network bandwidth usage, as well as the upgrading of the storage space requirements, such as 1080P HD screen, five times the clarity screen in SD D1, D1 resolution transmission only 1M bandwidth is needed to transmission and storage, to 1080P HD transmission bit rate up to 6M transmission and storage. Million-pixel high-definition camera for HD monitoring program construction, considering the input of the transmission and storage, choose the most suitable high-definition camera, rather than blindly select five megapixels, even million pixels; Perhaps 1.3 million, 2-megapixel ip camera is the most suitable choice. Megapixels HD ip camera, you must also choose the right camera lens, you first need to choose to use HD lens, if you are still using ordinary non-HD lens, you will not be able to exhibit ultra-high resolution megapixel HD ip camera effect. In addition, according to the application environment and to monitor the objectives and requirements of the different, but also to choose the right focal length of the lens, is to choose to meet the monitoring lens vision objectives and requirements. If you choose a wide-angle lens, the viewing angle is large, generally more than 90 degrees, suitable for monitoring large-scale, short-range establishments; select a telephoto lens, the viewing angle less than 20 degrees, is mainly used for a wide range of ultra-long-range environmental monitoring, such as a forest, stadium, harbor and other high-altitude look monitored. Million-pixel high-definition camera on the market lack of people with all kinds of different characteristics of the models, rather than the integration of intelligent video analysis technology, with a high-definition camera with features to become one of the highlights of the development of the HD camcorder, such as smart HD network cameras, intelligent video analysis technology megapixels HD organic fusion. Intelligent video analysis technology has become the mainstream of today's technology development direction, continue to be widely used, megapixels brings high-definition picture quality, video surveillance into the era of high-definition monitor, but did not change the traditional passive monitoring mode . Unfocused observed scene images of high-definition display, of course, to the monitoring personnel brought the intuitive experience of HD, but still could not change the number of monitoring site, easy to miss the passive situation. And then clear the screen, if police intelligence can not be the first time to the monitoring personnel receive the alerts, the effective value will be greatly reduced. Use of early warning efficacy of intelligent video analysis, the first time there will be a the police intelligence HD screen pop-up will greatly enhance the efficiency of its monitoring. In the era of traditional analog surveillance cameras, the camera itself does not have the video processing DSP chip, it can not be intelligent video analysis algorithm is embedded to the camera in order to achieve the intelligent monitoring need of additional intelligent video analysis equipment, the cost and maintenance effort are larger. Megapixels HD ip camera emergence of video processing DSP chips that motherboard, so you can achieve the intelligent video analysis algorithms embedded megapixels HD ip camera. Intelligent video analysis algorithms will be occupied by the processing power of the DSP, the order does not affect the video compression to ensure the quality of the video screen, as well as in order to ensure that the intelligent video analysis algorithms have sufficient computing resources to achieve higher performance, dual DSP chip manufacturers to adopt way, on the one hand, to ensure that millions of high-definition picture quality, on the other hand to ensure that the performance of the intelligent video analysis. Laid the foundation for the realization of intelligent video analysis capabilities megapixels network cameras. As we all know, intelligent video analysis is based on image analysis of events, the premise is the image, the image is clear or not directly determine the accuracy of the analysis of the events. Megapixels emergence of intelligent analysis to provide a high-definition image sources, intelligent video analysis accuracy also increased dramatically, has been a manufacturer of intelligent video analysis accuracy to the size of 3 × 3 pixels, If you do not have a high-definition The video source do to ensure, this precision is difficult to achieve. Megapixels HD ip camera appears, not only for our naked monitoring provides a high-definition image analysis to provide a high-resolution analysis of the source, as well as equipment intelligent, easy monitoring intelligent. As mentioned earlier megapixels HD ip camera applications that require high bandwidth to carry high-definition image transmission, all HD image transmission to the monitoring center for check-in staff monitoring, and will no doubt take up a lot of network bandwidth resources, The integration of high-definition video camera with smart technology, making the front end of the camera can be automatically filtered high-risk events, warning image filtered the chosen transmission of monitoring center, so that will greatly reduce the HD monitoring solutions rely on network bandwidth resources, dramatically reducing HD solutions of the overall cost.

For a single high-definition network camera, the main sync adjustment the following three types: internal synchronization, the use of hd ip camera inside the crystal oscillation circuit generates a sync signal to the completion of the operation; external synchronization using an external sync signal generator synchronization signal to the outside of the high-definition network camera synchronization input to achieve synchronization; linear locking or row locking AC power to complete the vertical promote the use of hd ip camera synchronization, HD ip cameras and the power zero line synchronization. System managers hope the video input signal is a vertical synchronization of multiple high-definition network camera surveillance system, which transform the output of hd ip camera screen without causing image distortion, but due to the monitoring system consists of more than one monitoring HD ip cameras, camera composition, power may be provided by the different phases of the three-phase power, or even the entire monitoring system and AC power are not synchronized, the measures to be taken at this time: by an external sync signal generator external synchronization input of the synchronization signal is fed into the high-definition network camera to adjust the synchronization. HD ip camera phase adjustment potentiometer, due to the high-definition network camera at the factory, the vertical sync on the rising edge of the in-phase AC power is zero crossing, each hd ip camera has a different phase shift through the use of phase delay circuit to obtain the appropriate vertical sync phase adjustment range from 0 to 360 degrees. All hd ip camera has a video amplifier from the CCD signal amplification can use the standards, the gain is equivalent to a higher sensitivity, can guarantee its sensitivity in low-light environments, however, the amplifier will overload so that the video signal will distortion highlight illumination environment, and to this end, we need to take advantage of high-definition network camera automatic gain control (AGC) circuit to detect the level of the video signal to switch the AGC timely, so that the hd ip camera can be larger illumination within the scope of the work, this is the dynamic range of the illumination automatically increases the sensitivity of the hd ip camera, thereby increasing the intensity of the image signal to obtain a clear image. HD ip camera usually the AGC working point is determined by the average of the contents of the entire field of view, but if a bright background area exists in the same field of view and a very dark foreground object, then the determined AGC point there may be inappropriate for foreground objects backlight compensation is likely to improve the prospects of the target display condition. When the backlight compensation is turned on, the high-definition network camera only for the entire field of view of a sub-regional average to determine its AGC operating point, if the foreground object is located within the sub-region, the foreground object visibility is expected to improve . The charge accumulation time of the imaging surface of the optical electric control to manipulate the shutter, the electronic shutter controls the CCD accumulation time in the CCD within the definition network camera is, when the electronic shutter is closed, for NTSC hd ip camera, the CCD accumulation time is 1 / 60 seconds; PAL HD ip camera compared to 1/50 of a second. When the the HD camera electronic shutter open, the the NTSC HD network camera electronic shutter covering the range from 1/60 sec to 1/10000 sec 261 Step by step 311; the PAL type definition network camera electronic shutter cover from 1/50 seconds to the range of 1/10000 sec. When the electronic shutter speed increases, the time allowed in each video field, focusing light on the CCD to reduce the sensitivity of high-definition network camera, the result will be reduced, however, a higher shutter speed for the observation of the moving image will produce a "pause action "effect, which will greatly increase the dynamic resolution of hd ip camera.

With the security problem is becoming the focus of attention, the development of security monitoring technology was more and more paid attention by all sectors of society, visible light surveillance cameras can no longer meet the monitoring requirements, 24 hours of continuous monitoring equipment is a important part in monitoring system now. To achieve 24x7 monitoring, you need a night vision ip camera, the current cameras mostly with infrared night vision function. The infrared ip camera technology into a passive infrared technology and active infrared technology. Passive infrared camera technology is the use of any object can radiate electromagnetic waves principle above absolute zero (-273 ℃), due to the different objects and even the strength of the radiation capacity of the different parts of the same object, and the reflection of infrared and use of objects with background radiation environment differences and the scene itself, various parts of the difference of the radiation, the infrared detector can strength ranging radiation signal is converted into a corresponding electrical signal, and then amplified and video processing, for human eye observation of the video image is formed, The thermal image is able to render the various parts of the scene radiation downs, which shows the characteristics of the scene. Different the same goal thermal image and visible image, it is not the human eye can see visible light image, but the target surface temperature distribution image can not clearly identify the target of the detailed features, can not meet the requirements as "evidence", and becuase of the high cost of passive infrared ip cameras, they are used in the military field usually , few applications in the field of monitoring. Active infrared camera technology is the use of infrared light emitting diode to produce infrared radiation to produce the characteristics of the ordinary network camera able to capture infrared light, auxiliary lighting scene and environment in the human eye can not see, the use of the network camera's image sensor can feel infrared light feelings the surroundings reflected back infrared light to get a relatively clear picture of black and white images, night vision surveillance. Therefore, the infrared ip camera is now the majority of active infrared technology, surveillance cameras use infrared lights to match. Active infrared technology is relatively mature four forms: Traditional LED infrared lamps: a certain number of infrared light emitting diode matrix composed of luminous body, infrared emitting diodes made by a material of high infrared radiation efficiency PN, plus the forward bias voltage to the PN junction the injection current excitation infrared light, spectral power distribution center wavelength of 830 ~ 950nm, half peak bandwidth of about 40nm it is narrowband distribution in the CCD feelings; second-generation array integrated infrared light source: It uses state-of-the-art packaging technology on the basis of the original LED infrared technology dozens of high efficiency infrared crystals encapsulated in a plane, integrated IR light-emitting chips in a small range, and made a "thermal isolation" processing, so that the entire part can be placed in any size, any shape of heat on the body, so as to solve the heat problem, no longer because of the high temperature and hurt other peripheral electronic components; third generation of dot matrix infrared light source: it is a highly integrated LED array chip technology, single LEDArray output of about 800mW to 3.6W electro-optical conversion efficiency is about 25%, the light-emitting body is a single light source, the light-emitting angle is adjustable; infrared laser light is a semiconductor laser, is the use of semiconductor material in the complex process of the hole and electron, and the decrease of electron energy levels and the release of electrons to generating light energy, and then forming a laser photons in the resonant photon propagation direction specification. Good directional laser performance for the beam angle is small, the energy is concentrated, and spread to the far distance there is still enough light intensity, it is very suitable for long-distance lighting. Active infrared ip camera with the infrared emission lights, its advantages is capable of showing the details of the target characteristics, and lower cost. But the disadvantage is that the irradiation distance is relatively short, The imaging results easily affected by the environment, especially in the fog, snow, rain, a little bad weather, mainly applied to the detection of target; PIR network camera without the aid of an auxiliary light source, the advantage to penetrate strong, irradiation distance. The drawback is that only render target surface temperature distribution of images, mainly used in finding the target. The infrared ip camera market is quite confusing, mainly due to the industry's lack of unified standards. For example, the infrared lamp irradiation distance is often the highlight of each company propaganda, not quite the same with each other, whether irradiation distance is measured under the conditions in which environmental illumination and presented the picture quality is no way informed that it is currently facing the most severe test of the infrared ip camera market, to get rid of this problem has become the focus of common concern between enterprises. Active infrared technology early, only 5% efficiency, the development of efficient 25-30% LEDArray technology, to meet the short-range to long-range infrared night vision technology breakthroughs, and laser lighting technology is to achieve long-distance night One of the best way to view monitor, and light intensity than conventional light sources stronger and more long-range night vision technology is a trend of the future night vision ip camera market. Active infrared technology and the integration of passive infrared technology will be one of the trends of the future, the use of passive infrared technology penetrating power, irradiation distance to find the target, the use of the principle of active infrared lighting acquisition target detail features can remote monitoring to provide strong evidence. In addition, another night vision technology - shimmer technology integration is also one of the future direction of development, progress in the dim light and infrared technologies respective period, taking into account the complementary nature of the two, in addition to the existing based on technical difficulty, how to LLL image and infrared image fusion to get better observe the effect of the two technologies has become a hot research current night vision technology development.

Addition to fixed cameras need a sentinel fixed focus monitoring various places in the city, and more need for flexible glanced monitor a wide range scenes PTZ controllable ip camera, so we see the traditional Ptz IP Camera and high-speed dome ip camera has been installed in theroad intersections, plazas, shopping malls, parks, environmental protection, water systems, power facilities and other places. Although these two types of products on the technical and structural similarities, but the functional difference is quite significant. Traditional Ptz IP Camera is generally composed of by monomer camera + lens + PTZ guard, front-end camera systems seem bulky and cumbersome, and involves components include: heating cooling parts, gun-type camera can control the zoom lens and PTZ decoder , wipers, infrared lighting, auxiliary equipment and so on, the power consumption of the power supply is relatively large, cumbersome installation and commissioning equipment connected coordination failure points, prone to all kinds of problems, the most critical in the monitoring range in the horizontal and vertical to exist monitored corner. However, it is easy to be equipped with wipers, auxiliary light, big zoom lens with high-performance gun-type cameras, etc., and can be assembled configuration of various types of special needs, so there are still vast battlefield. High Speed Dome Ip Camera is like a fixture containing a sealed protective cover PTZ (PAN-TILT-ZOOM) components, motor-driven PTZ: integrated camera movement module, control circuits, power systems, coolingThe secondary protection components. It involves optical, mechanical, electronics, electrical engineering, control software and more skilled, and has been a rapid development in recent years since the launch in 2000, and differentiation of many types of constant-speed, high-speed, MINI, digital network, the light side, vacuum intelligent high-speed ball machine products generally have the following key features: 1, precise and efficient structure, currently the major ip camera manufacturers have invested R & D technical indicators higher the camera integration movement, restore the true color, low-light, high-definition, high-speed, high zoom, fast focusin rising; addition quiet motor with higher-speed micro-motor, new smooth rotation mechanical to achieve precision high speed, high precision, can better adapt to a complex and changing environment of the scene and in a timely manner, quicklyefficiently capture the target locked, and the more distant or more detailed parts does not leak, especially based on this digital identification technology also can be utilized more effectively play. 2,Display a simple rationalization, the monitor screen to display the address of the high-speed dome ip camera, monitor site name, rotate the coordinate values for duty personnel directly provide clear information, dome ip camera menu operation tends to be more simplereasonable, including multi-language settings and comes with easy-to-understand instructions, easy to personnel familiar with the management of the equipment. 3, intelligent combination of user-friendly, intelligent dome ip camera is the most important function of editing software and superior CPU processing, dome ip camera have the preset position set, rocking scan, pattern scan, vectorscanning, dimensional inspection, the path of learning and memory, regional obscured telephoto speed limit, screen freeze, mirror flip, coordinate positioning, sight, automatic homing, automatic tracking, motion detection alarm functions, management can be based on the actual needs andpreset under program control, the ability to the smart ball machine active scan inspections the one hand, to reduce the duty staff strength, on the other hand no one state can be intelligent of duty, and the implementation of a higher intelligence preparedness. For example through intelligent clock control function, several Task Scheduler can be arbitrarily set by time, the camera viewfinder need to preset multi-point inspections, be authorized to respond to stop again converted to automatic when the managers involved in the control mode; Unicom trigger alarm input and output signals, trigger alarm signal lens Jump to the incident site, or timely sensing image when the screen changes prompted managers to monitor the situation of a region and can make the ball machine. 4, stability and security, as a monitoring device 7 * 24 hours of uninterrupted work is its distinguishing feature, an important indicator of the stable and reliable work of the monitoring equipment is also a high intelligence products, which is the first of the equipment itself rely on highly reliable mechanicalthe structural design and thermal heating within a reasonable working environment to ensure stable operation; followed by rational design of the circuit to protect the effective stabilizing of the ball machine, to prevent the intrusion of the overload current, especially to prevent lightning damage is also very important. Some Dome set overheating overload detection prompts to play a prompt protective role; authorized device connected system of multi-level management program again locked to play a non-executive staff intervene to protect the safety of the equipment is prohibited, which is security monitoring apparatus should have the function. 5, easy to install and easy to maintain, many manufacturers in product design, give full consideration to the ease of installation works, similar to-PELCO the Zohar buckle circlip, hot plug design have been widely used, very easy maintenance adjustment settings some dome ip camera also has a the REFRESH self-cleaning function remotely through simple internal gear set menu will be able to achieve self-cleaning adjustments. Continuously improve on the level of integration also makes the device more compact, and a variety of the mounting attachments housing came into being in order to adapt to different environments; appearance more beautiful, and better integration with the environment. Should be a good high-speed dome ip camera with compact features, make it visual modification installed and no matter in what place does not cause special attention, so that it is more subtle and does not affectmonitoring the effect of the overall layout of the place. High Speed Dome shape global shape, hanging, wall-mounted, embedded in cylindrical and hemispherical installation. Contractors or the user can according to their actual situation to select a suitable appearance of high-speed ball. High Speed Dome IP Camera is a camera device, the performance of the camera is important to select the parameters. Now the majority of the market as Japan and South Korea manufacturing integrated camera. Select fast dome ip camera magnification, do not consider multiple viewing distance, not the maximum focal length of the lens to select, say, 16 times the integrated camera (up to 63mm) 8-80mm, 10 times the three can zoom lens (max 80mm) to be far-sighted. Select magnification optical zoom as the main reference for the electronic zoom should not be counted, because the electronic zoom is in the lower image clarity premise amplification processing. In the the camera illumination of selection, 18 times SONY 23 times HITACHI use a different approach, but the use of effects is consistent, in the outside light below the critical illumination color screen for clear imaging, no manual control, fast ball machine can automatically recognize and automatically switches to black and white images (some vendors also provide manual switching function), and the two products mentioned above can be issued in a black and white camera status 0.01Lux. Fast PTZ High Speed Dome core mechanical components to determine the stability of the high-speed dome ip camera performance and uninterrupted use of its reliability. The PTZ rack part a result of the combination of stampings design is more convenient, so using this structure. But on the other hand, due to the composite structure is very high for the size requirements of the dozens of stampings, installation, transportation and use of the process is prone to problems, and other reasons, there are now fast ball manufacturers have begun to design requirements Cast aluminum rack design or injection rack design, improved batch consistency and rack stability. High Speed Dome also should pay attention to the motor, the majority of DC motors and stepper motors using DC motors run quieter and more balanced, but the high cost of the product, the control system is more complex, than the life of short manufacturers began using the stepper motor. Stepper motor has a low manufacturing cost, accurate positioning control, long service life, and many other advantages, and resolve the problem of the control and noise, high breakdown motor drive, to minimize image shake in low-speed high-power state reducing visual fatigue monitoring personnel. In addition, the high-speed dome ip camera than ordinary PTZ function better, its variable speed rotation can easily capture moving target; infinite-position rotary conductive ring design to ensure the capture of the target speed, improve system connection traction caused by life; 180 degree automatic rotation solve missing just below the moving target. Therefore, the integration of high-speed dome ip cameras, while more complex, is to use reliable multifunction PTZ system. High Speed Dome brain decoder, the only part of it is also the connection and external control system, all of its functions are achieved through its decoding, with optional should focus, in order to avoid the embarrassment can not control situation. Decoder with the control system command handshake is implemented through the same internal convention, which is commonly referred to as the communication protocol. Users should use the controller's control protocol type, ball machine to select a different type of communication protocol. The protocol type of the controller and high speed dome ip camera protocol type is consistent only tries to control, or High Speed Dome uncontrolled. Usually when the user has selected a certain control system, for example, the system uses the PELCO protocol the matrix controller or this agreement DVR, optional ball machine, you must select PELCO protocol fastball. camera, otherwise it will not control the situation. Imports fastball communication protocol is essentially self-contained and brought certain limitations to the user to select the control system, and now the fast dome ip camera with multi-protocol integration, and can be integrated with a variety of domestic and foreign common communication agreement, so that customers can be easily combined system.

With the continuous expansion and increasing market demand for applications of high-definition ip camera monitoring picture quality and camera features are required to improve IP HD cameras will be a gradual shift from a pure security surveillance cameras evolution into a set of multi-functional, easyoperation, easy to manage a variety of needs in one important part of the network monitoring system, specifically IP HD cameras there will be innovation and new applications in the following aspects: 1.HD IP camera have been attempts to combined with the Internet of Things, based on the Internet of Things, Radio Frequency (RFID) technology is successfully put into use, can achieve the seamless integration with high-definition video systems in the future Internet of Things. User to receive data from the RF transmission through the COM interface of the IP high-definition camera, do a combination of images and radio frequency (RF). For example, companies can use remote video scan instead of employees to work a fixed punch, district administrator through the surveillance video to identify illegal personnel, these applications will help to improve a lot of tedious work in practice, reflecting the high-definition camera intelligent, high-technology-based value. 2.IP high-definition cameras can be linked with other security alarm equipment, IP high-definition network cameras in APEXIS, for example, the cameras have an alarm (ALARMI / O) interface, the access of this alarm signal can be received by the infrared sensor detector, door sensorissued by the window magnetic sensor switch level signal when the IP high-definition cameras to receive this signal to its encoding processing, and then sent to the TCP / IP network through the application software of the alarm signal to set the alarm system linked responsestimulate such as sound and light alarm, the camera starts recording surveillance video, and security alarm host to send text messages to the user or by calling the user's phone. 3.With the popularity of the 3G network, each IP HD cameras have their own separate IP address, users can use a variety of mobile devices and network cameras connected through the 3G network, real-time transmission of high-definition images and video, remote monitoring of wireless network. The user can configure hd ip camera such as Email, FTP client, built-in IP HD camera can also Email, FTP, etc. to trigger the alarm when connected to the Internet, snap photos or video to send to your mobile device. The cameras can be connected via the COM port and the device can connect to the SIM card, using SMS, MMS sent to the specified mobile terminals. So that users only need to use very little bandwidth and cost will be able to do real-time monitoring and intelligent. 4.IP high-definition camera, front-end can bring their own operating system, so on the front of the camera comes with a lot of intelligent algorithms. These intelligent algorithm to deal directly with the original image information output from the chip, and then do some appropriate and suitable for the application of the characteristics of occasions. Entrances and exits, for example, the number of statistical functions, the function can be monitored by the camera screen analysis, automatic statistical calculations through the important entrances or designated area or the number of objects. But also in low-carbon era, combined with intelligent algorithm with energy saving and environmental protection ideas opens up another huge market in the party and government organs, schools, businesses and large home environment, the user can use intelligent video analysis technology to eliminate the huge waste of electricity and security risks, such as automatically turn off unnecessary lights, open office work lights or adjust the light intensity according to actual needs.

With the rapid development of network technology and network camera, all-Digital IP Camera system using computer technology and digital processing technologies gradually became popular, and occupy more and more of the market.Video surveillance network has significantly improved image quality and solve the problem of image effects in the traditional monitoring, changed the traditional complex connections, access Web ip camera and implementation of the system more simple and convenient.But at the same time the pressure of the huge storage requirements and network transmission. H.264 compression technology has the video compression to minimize, but still not solve these problems. The cloud storage to break the traditional storage performance and capacity bottlenecks, the technology to link a large variety of different types of storage devices in the network in order to form a very powerful storage capacity, performance and capacity greatly expanded, so that storagemassive video surveillance data has become possible, so that enterprises have a storage capacity equivalent to the clouds without having to pipe the actual storage, so as to solve the storage problem. The cloud storage is a new concept for the extension and development of the concept of cloud computing, cloud computing is a system through the Internet will be a huge amount of calculation processing program automatically split into numerous smaller subroutines, and then handed over to multiple servershuge system has been calculated and analyzed the results back to the user, change the storage site means clustering applications, grid or distributed file system functions, the network a large number of different types of storage devices through the application of softwaretogether to work together, a common external data storage and business access capabilities. The structure of the cloud storage system model consists of four layers: the storage layer, infrastructure management, application interface layer and access layer.The storage layer is a fundamental part of the cloud storage, cloud storage in the storage device is often a huge number and may be distributed in different regions, with each other through the network linked to the basis of management through the cluster, distributed file systems and grid computing, multi-kinds of technology to achieve interoperability between multiple storage devices in the cloud storage, so that multiple storage devices as a device can provide the same kind of external services, and to provide more powerful data access performance. The application interface layer is cloud storage is the most flexible part of the different cloud storage providers can be based on actual business needs, develop a different application service interface to provide different application services; authorized users through the standard public application interface to Login cloud storage systems, to use a cloud storage service. Different cloud storage providers, provide access to the cloud storage types and access methods are also different. Cloud storage enables storage virtualization, which can greatly simplify the application link, the construction cost savings for customers, and to provide customers with a more stable storage performance and more powerful sharing capabilities, cloud storage device on the user completelytransparent, any local user can be authorized through the network cloud storage to connect into the space and access to data. Users do not have models, network, storage protocols, application interfaces, and other details of the storage device, the application is simple and transparent. The most important issue in the use of cloud storage is its safety and reliability. The following questions must be taken into account, how to ensure that customers anytime, anywhere access to network(ip camera) video surveillance data, and how to ensure that cloud storage servers is 7 * 24 hours of uninterrupted work, and how to ensure that monitoring data will not be other people to steal, and so on, ability to solve these problems is the key to cloud storage can really use up.

Compared to analog cameras, IP cameras to the user is a technical change and the new user experience. At the technical level, the traditional white balance, backlight compensation, wide dynamic technology has the lowest standard. Technology is evolving progress, the IP camera is the reason why such a rapid development, the security industry, the fast-growing market demand and network system architecture construction is the foundation, and camera manufacturers continue to intensify R & D, investment and fierce market competition is the most important reason, IP cameras not only in technology, functionality and design are ever-changing. The development of IP cameras With the rapid development of network video surveillance and digital video processing technology continues to change, traditional infrared cameras in recent years more and more to the development of network-based, high-definition direction. 07 years ago, some IP surveillance vendors began to launch early IP infrared camera. But in general this group of IP infrared camera only supports up to CIF resolution, there is no dual-filter design, infrared light is the most common technology is the product of the early experimental. 08,09 years, video coding processing technology and applications become more sophisticated, IP infrared camera support D1 resolution more appeared, and with the popularity of network video surveillance more and more applications. This group of IP IR camera with a professional LED infrared technology, infrared working distance can cover 15 meters to 80 meters. 2010, with the rapid rise of high definition video surveillance, a new generation of IP infrared camera - high-definition infrared network cameras have begun to emerge, these cameras not only the sharpness of the image to achieve the 720P, 1080P HD, but also uses the latest generation of infrared light technology, with a high-end dual-filter design. Network HD technology along with the rapid penetration of the city in peace, some of the more high-end high-definition infrared network cameras more and more typical HD laser PTZ network cameras such as Kodak, the camera is configured with 100 m infrared laser light, 18 times high-definition movement, safe city in high-end products. In addition, high-definition infrared fastball, high-definition infrared gun with infrared hemisphere is also developing rapidly, the attention of a lot of IP surveillance manufacturer. The security market a wide range of products has been a certain lack of industry standards, this is one of the conditions of restricting the big security building. In recent years, SONY, Axis, and other well-known IP camera manufacturers to self-organized ONVIF are certain industry standards and corporate self-organized formation of standards, but its response to get more and more enterprises look to the IP camera , or has very important significance. I believe that within the next few years, the standardization will be the IP camera to the market permits. Transmission technology to further enhance the construction of IP cameras can be an important foundation for development and progress of technology. Currently in a safe city, financial and network monitoring projects are usually self-built fiber-optic network or local area network 1000M-bandwidth networks. This Gigabit bandwidth resources, installed in the front-end 1080P Full real-time HD network camera 100 road (even if the per Road resource 4Mbps calculation), and occupied less than 50% of the total bandwidth resources; 720P transmission, bandwidth can also be reduced by half, This can effectively support the practical application of high-definition network camera. In addition, the deployment of 3G mobile data networks, wireless networks become possible as a video image carrier, mobile video surveillance is an important future development direction. 3G video surveillance is a typical representative of 3G multimedia services with high-end and differentiated characteristics, emergency command, bus monitoring, and other professional fields, but, of course, by phone with 3G network can view the features of the monitor screen. let it also applies to ordinary consumers, to achieve the civilian population, family and public service-oriented. The future, as monitoring technology continues to improve and develop the IP camera as the main direction of one of the monitoring technological developments, combined with optical imaging technology, intelligent analysis techniques, and network transmission technology, and so bring new changes, continue to meet the demand for market competition at the same time, tend to be a self-perfection. A profound impact on the monitoring technology, and it will profoundly change our way of life. The core technology of IP cameras Future trends in technology for IP cameras, the Hikvision front-end product line manager Xu Xuan was said: "IP cameras future trends in technology: HD trend, the COMS gradually replace the CCD, intelligent analysis capabilities, standardization, and transmission technology further improved. HD technology gradually in-depth Today, the most prosperous of the concept of monitoring is high definition and application, and the success of many large-scale projects also shows that the HD monitor has gradually become the mainstream. Development of high-definition IP cameras can be described by leaps and bounds, in addition to the current contact with more megapixels, 1.3 million pixels, 2 million pixels, 3 million pixels 5 million pixels, 8 million pixels of products on the market, or even tens of millions and ten million The above pixel products are inklings in the surveillance industry. Other high-definition network camera investigation found that: since 2009, with the financial, transportation and other industries as well as the peaceful city part of the project HD monitor high demand, coupled with the Shanghai World Expo, Guangzhou Asian Games and Shenzhen Universiade and other large activities to promote the trend of high-definition monitor, HD network camera (resolution greater than or equal to 720P) rapid growth mushroomed. Some mainstream network video surveillance, such as Panasonic, Sony, Hikvision, Kodak, Axis, Dahua, Yellow River and other vendors have been offering megapixel network cameras in high-definition network monitoring field, a new round of contention. The survey shows that the domestic high-definition network camera in 2010 annual shipments of over 200,000 units, compared with 2009 growth of more than 200%, about 34% of total network camera. In high-definition network cameras, megapixel accounted for 56%, accounted for 37 percent of 2 million pixels, 3 million pixels or more accounted for 7%. Noise reduction technology and improve Today, 3D digital noise reduction technology with super wide dynamic IP camera is also very common, and if placed in the past, but proud existence. Of course, new technologies are constantly applied to the IP camera which Such as the Hikvision smartir technology. The technology uses intelligent image processing technology to intelligently adjust the brightness curve through the multi-block brightness of the detected image, thereby preventing the image overexposure and lack of exposure phenomenon to solve the problem of the infrared camera near overexposed, so that uniform distribution of image brightness, the screen restore a more realistic, delicate. Axis "seek light" technology. The technology of illumination has high sensitivity, the camera even in a dark environment, step down and see the monitor object. Panasonic SmartHD technology, the technology embodied in the first high-definition, another technical feature is the intelligent analysis, in fact, is a comprehensive reflection of Smart and HD. CMOS promote the development of network cameras The image sensor as a core component of the IP cameras, CMOS has gradually instead of the CCD trend. With the development of technology, the CMOS sensor's performance is being improved rapidly. CMOS sensor response speed faster than CCD, better lower and therefore more suitable for large amounts of data and high-definition monitor. From a market point of view, the traditional manufacturers of CCD SONY has begun to shift the focus of the CMOS sensor in its production of high-definition network camera is almost exclusively using CMOS sensors, which may be regarded as one of the CMOS sensor The initial victory. Intelligent video analysis technology in-depth Intelligent video analysis can be said to be another hot addition to the IP camera HD concept. Has been achieved in high-definition network camera or intelligent analysis functions are implemented: video block detection and video loss, video change detection, video fuzzy detection, video motion detection, entrance people counting, crowd movement and congestion identification. items left over recognition, intrusion identification.

With the rapid development of network video surveillance and digital video processing technology continues to change, traditional infrared ip camera in recent years more and more to the development of network-based, high-definition direction. 07 years ago, some IP surveillance vendors began to launch early IP infrared camera. But in general this group of IP infrared camera only supports up to CIF resolution, there is no dual-filter design, infrared light is the most common technology is the product of the early experimental. 08,09 years, video coding processing technology and applications become more sophisticated, IP infrared camera support D1 resolution more appeared, and with the popularity of network video surveillance more and more applications. This group of IP IR camera with a professional LED infrared technology, infrared working distance can cover 15 meters to 80 meters. 2010, with the rapid rise of high definition video surveillance, a new generation of IP infrared camera - high-definition infrared network cameras have begun to emerge, these cameras not only the sharpness of the image to achieve the 720P, 1080P HD, but also uses the latest generation of infrared light technology, with a high-end dual-filter design. In recent years, the rapid penetration of the network HD technology in areas such as Green City, some of the more high-end high-definition infrared network cameras more and more, such as high-definition laser PTZ network cameras, the camera configuration 100 m infrared laser light , 18 times the HD movement, safe city in high-end products. In addition, high-definition infrared fastball, high-definition infrared gun with infrared hemisphere is also developing rapidly, the attention of a lot of IP surveillance manufacturer.

Why is Waterproof IR IP Camera flicker? When the light intensity below the threshold, the infrared light on luminescence. Higher than the threshold value is off. We consider, lighting intensity is slightly lower than the threshold of the case: photosensitive element detects light intensity is slightly lower than the threshold value, control IR LED on LED - light emitting infrared light, the detected illumination increase (with a reverse back infrared light), and exceeded the threshold value, control infrared light off of the probe to reduce the illumination once again control the infrared lamp is turned on. This back and forth constantly, causing the image flicker. This happens, is the principle reason, do not say it is normal, at least not the product quality. First, the extended the IR waterproof Ip camera use infrared light time, affecting the life of the product; Second, the situation can produce color images on the infrared light will cause the image quality down time; Third, the color image to generate infrared eye (infrared eye is determined by the principle that people want to see the phenomenon). Low threshold, there may need to add lighting at the time, infrared light can not be open in time. The IR waterproof ip camera is now common, the general environment in which the photosensitive element to detect the light intensity, according to the design parameters identified in the threshold to produce control signals for infrared light is turned on. Threshold level, by the use of the environment, the user's preferences, designers consider various factors, the importance of the different manufacturers of various products is not the same. If 20,10,5 Lux. And so on. Threshold is high time to open earlier, the camera may not be the conversion of color to black and white, infrared light to open up. These three areas will be negative.

A clear high-definition technology bottlenecks and obstacles Affect the definition of large-scale application of the bottleneck, the first is a technical issue, the promotion of high-definition, there are still technical obstacles. For example, CCD sensor power consumption, CMOS wide dynamic sensor problem. Second, price is also high. Once again, the user's understanding and acceptance of a process. Currently, the market leading HD monitoring equipment is high-definition camera. Cost, low-light sensitivity and other key issues, most of the HD camera performance is not satisfactory. HD IP cameras currently used in the chip, there are two, one is the CCD, the chip technology is relatively mature, but the cost is higher; and the other a CMOS chip is more expensive, but its drawback is that in low light cases, more noise. As most of the HD cameras are using CMOS sensors, the lower its sensitivity to light, even the use of megapixels CCD sensor than the average low-light CCD also have much lower sensitivity. To the night is dark, and monitor most of the time period to prevent precisely at night, so that would make the high expectations of the system into a high-definition video display. Traditional analog video camera manufacturers in the processing of production experience and have a certain foundation, but in the digital high-definition cameras and network video standard is not formed to promote open, the front of the camera manufacturers do both, but also development and production of back-end recorders and monitoring software, This is a process-based simulation prior to a general lack of camera manufacturers have accumulated. In addition, digital high-definition optical light sensor inside the camera and image processing technology, manufacturers generally do not accumulate in this area of development. Traditional common network cameras and video server manufacturers, software in the background, they will accumulate some experience, but also analog video camera manufacturers have encountered the same resistance. Semiconductor companies want to make a complete technical solution, hope that any company can produce, but also limited the formation of network video standards and promotion, the company must provide a variety of light-sensitive semiconductor devices of illumination, infrared, wide dynamic full range of video camera and a wealth of back-end equipment and the core software, in order to attract a large number of manufacturers do not develop into a million high-definition processing vendors. Before the era than the semiconductor analog camera program will also provide free complex. Second, a large transport and storage challenges The application of high-definition only in some industry solutions, in some industries there are some applications, in the regular monitoring of the market, high-definition monitor has not spread, the network environment is also a limitation of this rigid quotas to promote high-definition video surveillance is an important factor. From the technical standards in terms of, 720P resolution is CIF ordinary SD 9 times, 1080P resolution is currently the CIF SD about 20 times, front-end HD cameras will undoubtedly bring a huge data flow, and the system can not achieve high-definition, the first face of the transmission system is able to accept such a large high-definition data streams. Transmission of high-definition monitor current IP networks are based on the way, it can not access traditional monitoring systems, the traditional access control system can only use high definition SDI or SCDMA mode of transmission. This transmission of the transmission distance is limited and can only be achieved through the fiber link, but the HD-related equipment has just started, the equipment cost is very high. And even with fiber-optic transmission, but also solve the problem of real-time browsing, video storage still can not get rid of encoding and IP transmission. Network HD camera is the main force in high-definition surveillance systems, and thus network monitoring has become the most economical high-definition transmission mode selection, but also being affected by network bandwidth constraints. There are three ways network, first 3G wireless network, and second, Wireless Network, the third is the optical network. If the transmission high-definition video, fail to meet requirements of today's 3G wireless network. HD video requires 2MB upload bandwidth, and today the upload bandwidth of WCDMA and CDMA2000 is only 600KB to 800KB, TD-SCDMA to be more bandwidth is narrower, and such conditions can only transmit lower resolution bandwidth of the 4 channels CIF or D1 all the way , also can not transmit high-definition video. Based on the current size calculation megapixels HD 720P, D1 stream is about 2 times the bandwidth of 4M, while calculated to 1080P, D1 stream is five times the bandwidth used is approximately 10M. With 100M Ethernet, for example, under the premise of ensuring smooth, in fact, about the same time can only carry 5-way high-definition images, but if the same video source with multiple user access, the bandwidth will be even greater. Gigabit Ethernet can take into dozens of roads, high-definition surveillance systems for small-scale, can be an effective solution for large projects, the transmission performance will become a stumbling block. At the same time, it means that high bit rate HD resolution, which is not only just for monitoring hard drive with a greater challenge, but for the entire storage system capacity, performance, cost is no small challenge. The most basic 720P HD monitor, for example, the normal hour video about the hard disk capacity required 4G8G / hour, for economic considerations, to reduce the compressibility of 3GB per hour video about capacity. In this instance, the calculation of time saved by a month, 8-way monitor about 17T (17000G) capacity is about, which just drives the price of conversion of million. Doubling the video capacity, will inevitably lead to a doubling of storage costs. Relatively high investment in high-definition applications, which mainly invest in infrastructure and investment in the system itself. The deployment of high-definition system for storage, network bandwidth requirements and other infrastructure facilities, higher than the SD system; and the cost of HD equipment itself will be a lot higher than the standard definition product. From the user's consideration, the current market is not mature, the cost of expensive high-definition monitor general security does not meet the requirements of the market, people are more inclined to use the network video surveillance, or even mixed system, after all, the cost of the entire security project for the Chinese Security Market is still quite high. For many ordinary users, investment cost is an important factor in their choice of one further.

Review the history of IP Camera, network cameras from the birth of the needs of people for security, it is mainly used in the beginning of the cause of public safety. Such as urban transport trajectory control, prisons and other state security career security guarantees. Superior performance of the network camera to go beyond the traditional monitoring equipment, such as the replacement for analog cameras. Network cameras replace analog cameras, have become a necessity. However, high-tech security network camera technology while at the national security field have been widely used in the domestic civilian market has been the position is not clear. Reporters interviewed the network on this issue as no superior brand marketing manager Yep, he said, the network camera uses can be divided into two types, one is the use of social and public security level, that is part of the field of network security camera slightly . Another category of products used in the civilian market, such as home. European and American countries and neighboring South Korea, Japan, the network cameras into the homes of ordinary people have. The domestic civilian market has been a very good potential business opportunities, civilian-based network video products should belong to IT class, this is the product characteristics and consumer target is determined. Industry experts believe that once the network camera into the civilian market, its development path like consumer electronics, consumer electronics category as IT has become a necessity. With security awareness, security IP camera into the homes of ordinary people has become inevitable. The advanced science and technology benefit of the people is the basic network service as worry-free philosophy of the brand since Premier Wen put forward the concept of safe cities, the network camera is the development benefits greatly.

In modern monitoring system, multi-camera tracking a major challenge is how to maintain the continuity of different targets identified in the FOV. While still camera network can cover a wide area, but within the monitoring area of the camera in order to increase the viewing angle, the image resolution is thus reduced; when there is no overlap FOV, signal processing must still be performed on a single data source. Therefore, the introduction of the PTZ camera to the development of a network of cameras to bring a new application advantages. Dome (PTZ Dome) is an integrated dome, which has operating speed, optical zoom, precise positioning and flexible control features, along with the entire process of digital surveillance industry, network, development of high-definition, PTZ network cameras on product development also entered a new phase, HD PTZ cameras to become the new hot spot monitoring industry, its main application has the following four advantages. ALL IN ONE, namely a network cable to achieve transfer all the data, which is an important advantage of network monitoring. Power over Ethernet IEEE 802.3af (POE switch terminal voltage is 48V DC, the maximum power 15.4W), only suitable for fixed network cameras and fixed dome camera power supply. High PoE, 802.3at support in the voltage range 50-57V DC, standard process for 53VDC, maximum power support 30W, to fully cover the dome and its power. Through High PoE, domes do not require any video cable, audio cable, control cable, power lines, etc., simply connect a network cable, you can connect all the cables. In order to shorten installation time HD PTZ network cameras, and to better ensure the quality of the installation fastball, more particularly network HD PTZ Camera Outdoor PTZ HD camera at the factory, it has been configured and pre guard IP66 good stand, out of the box, enabling quick installation network fastball, and can fully guarantee the quality of the installation. PTZ dome camera, depending on its mechanical structure, can be divided into high-speed dome and PTZ cameras are two types, the two types are collectively referred to as PTZ dome camera. Use of high-speed ball shaft drive, solid structure, can achieve a 360-degree continuous rotation, but the cost is higher. The PTZ camera gear transmission, due to the presence of the limit, you can not achieve 360-degree rotation, but the low cost. So, can achieve 360-degree rotation and ensure lower manufacturing costs 360 PTZ cameras automatically flip technology has also been applied to high-definition PTZ camera. This dome camera with PTZ cameras, like the use of gear, but also limited spaces. When the camera 360 degrees horizontal rotation control, when it reaches the limit, the camera will rotate 180 degrees horizontally reverse within 0.1 seconds, 180 degrees vertical reverse rotation, after skipping the limit, continue to rotate in the direction of personnel control in order to achieve the continuous rotation of 360 degrees. Without requiring continuous rotation of the camera for a long time, the only hope to achieve a 360-degree surveillance, and hope the price is low fastball, the camera of this structure is a very good choice. Under normal circumstances, this automatic flip the dome structure, its horizontal rotation speed and vertical speed select the speed can reach 300 degrees / sec, and according to the zoom, automatic adjustment of the rotation speed, thus ensuring precise telephoto limit speed. HD PTZ camera technology, making further improve the application needs to monitor. Particular network-based camera control and operation, require high-definition PTZ is able to quickly respond to the control command, and to achieve the rotation and zoom of the camera. Typically, there are two main HD PTZ camera control mode: joystick control and drag the center control. When using the joystick on the PTZ camera control, it is difficult to achieve accurate positioning control difficult. But the use of "the center of control" mode, you can freely control the heart. "The center of control" mode, the mouse on the image displayed as a "+" icon on the monitor image, the mouse point where the camera will be to the point as the center, auto-rotation, precise positioning to that point. When you want to zoom in on a target, you can press the left button while dragging the mouse, framed the goal, you can achieve the goal of automatic horizontal and vertical positioning and zoom. Autonomous intelligent automatic PTZ tracking enables the camera to pan and zoom conduct their own autonomous PTZ drive, and automatically control the PTZ camera PTZ full rotation and zoom lenses, visual guides for automatic tracking of moving objects are locked, in order to ensure continuous tracking targets to enlarge close-up screen appears in the center of the lens, so that security personnel can more clearly see the information, but can also be used after the evidence. Automatic PTZ tracking module makes up a fixed camera surveillance tunnel vision drawback is the perfect security monitoring systems necessary functions. Intelligent PTZ tracking and monitoring system with automatic target analysis, and with a high resolution camera, high-magnification optical zoom lens and a high-speed head, you can quickly, accurately and automatically capture the suspicious target. By setting intelligent vision PTZ preset automatic tracking and monitoring system can achieve preset scan, auto cruise and other functions, but also to achieve the many special requirements intelligent monitoring.

Abnormal installation of DVR software The first one is resolution mistakes while installing. The quality of color in display devices must be adapted to 32 pixels and the resolution with 1280*1024 or 1024*728. Secondly, the file for drive and hardware cannot be found. As is often the case that software can support and analog hybirds. You need to turn down your personal computer, unplug the card and clean it of change a slot to install. No image displayed At first, your should check the operation of power. Under the normal condition, the red indicator would be always lighting on the back of wireless network. POE IP Camera can work well on conditin that PDVR and POE switchs could be empolyed simutaniously and connect ordinary personal computer to DV12 power. Then, check the network, if fixed IP used, the local area network of personal computer must be in accordance with that of camera. In normal condition, the yellow indicator should be lighting and green indicator twinkling. Thirdly, check the configuration of software of ip camera and whether the len cap is open or not. IPs for each of them differ for your adoption of local area network. At first, your should check the operation of power. Under the normal condition, the red indicator would be always lighting on the back of wireless ip camera. POE of camera can work well on conditin that PDVR and POE switchs could be empolyed simutaniously and connect ordinary personal computer to DV12 power. Then, check the network, if fixed IP used, the local area network of personal computer must be in accordance with that of camera. In normal condition, the yellow indicator should be lighting and green indicator twinkling. Thirdly, check the configuration of software of IP camera and whether the len cap is open or not. IPs for each of them differ for your adoption of local area network. Abnormal images displayed Unclear images. You are expected to use hundreds of solutions len and better effect would be given. Check the focus length and adapt it untill clear images displayed. Moreover, discontinuous images and the images easily get stuck. In this case, you need to check the condition of resources used and CPU/RAM occupied. Alteration of IP of ip wireless camera. At first, we can change IP only when they are connected and images displayed. It is usual that there is no image after changing IP. It would come into effect after restarting the software. Another case is that you forget IP after alteration. You should reset the wireless network with the reset button pressed for 10 seconds. If it doesn`t work, you need to send it to the factory for repair.

IP network able cameras have caught up with analog camera technological know-how, and now exceed the superior of the video clip from regular CCTV cameras.The most important positive aspects of an Network IP based mostly video clip surveillance program is:A finish digital remedy, no will need for DVR's or DVR cards. Ease of set-up, no video clip cables to operate. Ability the camera around your LAN, no electrical power cables to run. Pan-Tilt-Zoom is made in, no will need for additional hardware. two-way audio is designed in, now you can hear and speak to the human being. Interlace challenges are eradicated in higher resolution cameras. The video clip is safe, and can be quickly scalled as you requires increase. These are the most important rewards of a network surveillance technique over an analog surveillance procedure, so you can make an educated judgement in advance of you purchase a new system, or upgrade an current CCTV dependent method. You really should know that ip camera are a lot more high-priced then CCTV cameras, as they are regarded a minimal personal computer by the network, and have the digitizing hardware developed in.The cost of installing a network camera process starts to pay out for alone following 8 cameras, as you have a diminished labor expense because of to no video clip cable to operate, you just hook up a swap to a neighborhood region network and run your IP cameras off that.TBS Error: 1An IP camera enclosure can make certain your IP cameras are secure the two from normal factors this sort of as wind, rain and snow, and from vandals or criminals who may attempt destroying the cameras, in order to commit crime on your residence devoid of staying discovered.If you are hunting for enclosures for an digital ip camera that's getting held indoors, it is oftentimes much more useful to utilize a smaller, significantly less large-duty equipment. These come at a more affordable value, but of program do not give as sturdy a defence as the far more highly-priced styles.When in an exposed, out of doors area, intanet ip camera will need to be protected from the normal factors. Rain and snow, as nicely as excessively warm or cold problems can result in issues with the mechanics of these devices. If you might be purchasing an enclosure to safeguard cameras from rain, be specific it is completely sealed when setting up. Having said that, you will need to also be convinced to allow appropriate airflow to the digital camera, as a digital camera in a sealed enclosure has the prospective to overheat.It is also probable to order enclosures outfitted with heaters and blowers to control the temperature inside of, perfect for the coldest and most popular months. Make certain that the temperature circumstances of these products matches that most acceptable to your cameras.Enclosures can, at occasions, have a intricate set up procedure. Before paying for, try obtaining downloadable manuals or guides on the enclosures you are taking into consideration, to see which will best suit the situations of your protection method.It is really also crucial to test and make certain the ability conditions of your enclosure can be managed.

Wireless security camera systems can beat any form of other ip camera systems. This is certainly not surprising for those who have installed wi-fi cameras within their home, shops or even business office and are living a happy along with secured life. On this know-how oriented planet, where you should find wireless variations for all sorts of systems, wifi ip camera are usually thought-about the top camera techniques for all your safety measures considerations. Here's 3 simple reason why mention the fineness of those wireless home surveillance systems over the basic wired digicam systems. 1. Presentation Simple to deploy, these mobile security surveillance systems provide clearer visual price to it has the users as compared to the wired mini ip camera. Your business does not need to be concerned about the length of the wires, gift wrapping the cables carefully a great quick access to the cameras or maybe selecting the position for the installation of the particular cameras. It's possible you'll install ones security cameras anywhere you wish, without diminishing at all making use of their effectiveness as well as result. 2. Easy accommodation Setting up the surveillance camera systems inside the right spots is the only factor that issues the workers. The cellular security surveillance systems can be put in easily any place based on your own security prerequisites. This is difficult while using wired methods which degree of proper area and accommodation for their set up. The cellular security cameras can be simply relocated from one area to the other based on ones security needs, thus making it simpler for you to monitor your home, retail store or business office. 3.

To protect the entire range of home security, home network camera meet ordinary family needs to solve two major problems: Security: the protection of the entire range of home security, avoiding theft, fire, etc. Members of the surveillance: comprehensive understanding of the elderly and children staying at home and timely understanding of daily life, games, and sick and so on. And for emergencies, but also remote assistance. Currently mainly provided by telecom operators ADSL broadband network (or 3G network) to achieve. As follows: 1, video surveillance: the living room, balcony, gate that customer needs in the presence of hidden location, install the "mesh" network camera surveillance to protect all hidden areas. 2, the alarm: the key parts of the motion detection function can be set or installed alarm sensor, the alarm works once the alarm event notification in time to the user; alarm can also automatically capture images, automatic alarm recording functions. 3, the video:it can be stored in the video and pictures stored on your hard drive. 4, remote video monitoring: each "mesh" network camera uses wireless or wired network, access home router, router access via ADSL broadband telecommunications network operators, fixed by the domain name or IP to bind to the video transmission public network, remote monitoring. Achieve results: The home video surveillance camera, allowing users to achieve effective real-time remote video surveillance anywhere , alarm linkage of a variety of ways to achieve functionality. If the owner usually travel to work or temporary use of the video surveillance system that can observe the home site in time, and if there are the elderly, children staying home , you can also keep abreast of their daily life, games, and sick and so on. And for emergencies, Remote Assistance also can handle.

There have been many amazing advances in security network camera during the past decade, but one of the most exciting technological advances of the past few years is the advent of IP cameras as an affordable option for home security video, making it one of the best ip camera choices available. IP stands for Internet protocol, and IP cameras are a type of ip video camera that enable a business or home owner to see what the cameras see via any device that has Internet access, from desktop computers to Netbooks to smart phones. The homeowner can log in on his or her computer or phone at any time and from any location in the world, and view a live feed from the ip camera . It's truly a hands-on form of up-to-the-minute video camera surveillance. Be careful not to confuse IP wireless security camera with webcams. Webcams are the small cameras built in or added to a specific computer, used primarily for socializing or video conferencing over the Internet. They are used as communication tools and can only work with the computer to which they are attached. IP cameras, on the other hand, are independent cameras that can be placed wherever the homeowner or business owner would like, indoors and out. They are often wireless and are more expensive than webcams. Instead of socializing, they're used for surveillance and monitoring, with feeds that can be viewed from any computer, as mentioned above. The advantages of IP cameras are numerous. They offer integrated audio, capturing sound as well as images. Most of them are motion sensitive, immediately beginning to stream images after motion is detected, which insures that you don't received hours and hours of images of an empty room with nothing happening. Some even notify you by email as soon as their motion detector is activated, so you can immediately check the premises to see what tripped the camera's motion detector. Many IP cameras offer remote zoom and pan features; while you are watching the streaming images, you can tell the camera to zoom in or pan across the viewing area. Some even come with night vision capabilities and can record in low light or the dark. Another advantage to IP cameras is ease of use. Many of them are what is termed "plug and play." They come with their own software, are wireless, and are easy to install. Furthermore, IP cameras are digital which means the images they record are clear and crisp, and storage of them is no longer the hassle that it used to be. You don't have to worry about keeping records on tapes or discs, which can be lost or broken.
