Cloud Storage in the Network Video Surveillance System

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.
