Video Surveillance With Fire "network Storage" And "epon"!
From the video surveillance system architecture point of view, as the number of front-end video collection equipment and network complexity of the rapid growth of the deepening, more and more of the video image processing functions transferred to the front end, which greatly promote the related equipment, video collection equipment video image processing software, network cabling Technology And storage technology.
Video surveillance network, showing a "distributed processing + centralized management" trends. From the video surveillance system architecture point of view, as the number of front-end video collection equipment and network complexity of the rapid growth of the deepening, more and more of the video image processing functions transferred to the front end, which greatly promote the related equipment, video collection equipment , video, image processing software, network cabling technology and storage technology.
IDC Research, the Chinese computer systems analyst, said Wang Shan, 2008, new trends will drive IP monitoring equipment and Solutions Further development of the relevant companies to create new opportunities.
All in video surveillance Product Session, storage and transmission of the important role the program has become increasingly prominent, network storage and provides high bandwidth access for large-scale commercial EPON has become dependent on two important technologies. Government, operators promotion Safe City Global eyes and wide horizon and other video surveillance project for the realization of the unity of cross-regional monitoring, unified storage, unified management, resource sharing network of monitoring a wide range of public, should large amounts of video data to be transmitted, management, video processing, etc. , is to promote the network storage and EPON in the industry.
Present, relative to the real-time display in the control center of a large-screen multimedia information, the greater the need for long-term storage media information for the future of information retrieval and media playback, providing evidence for the historical information services. Therefore, Expert That the monitoring system in the building, to be configured large enough storage devices to meet the needs of a large number of information storage media, in order to meet the demand for high-capacity centralized storage, storage devices themselves need to adopt advanced network storage technology to ensure flexibility of space for expansion .
In addition, due to the increasing scale video surveillance systems, more and more wide distribution range, resulting in operational shows more on that each video bandwidth needs of the business, often between 1 ~ 10M characteristics, previous ADSL has been difficult to meet, video surveillance vendors will EPON technology into monitoring program: monitoring by an optical fiber multiple access points, to solve the problem of mass access. Optical access system, for data, voice and video integrated service access, and has a good economy.
Promote an industry speed up the storage network
With the rapid development of information network technology, business platform through the center of centralized management and control to Network Video For the front end server and IPCamera network video monitoring system began to be widely deployed. As the structure is reasonable, expansion flexibility, clear layer, network video monitoring to give users a new experience in security applications, to rapidly build next-generation video surveillance system as the main form. Distributed front-end and platform architecture, centralized management and control, as well as flexible and convenient user access, making network video monitoring system also began to store part of the network. Network storage for video surveillance has brought a new storage architecture, on the one hand, the user more flexible deployment of storage, access and more simple; the other hand, the need to achieve a large storage building video surveillance system is also more convenient .
Gradually from the video monitor trends in network development, network storage will be in the future of video surveillance systems play an increasingly important role. Network video monitoring system made from two aspects of networked storage requirements: First, deploy and access the network; second network storage device itself, the network video monitoring is very suitable for large-scale monitoring and control network applications, in order to meet the large capacity centralized storage needs, storage equipment itself to the use of advanced network storage technology to ensure the space for expansion flexibility.
Present, "Green City" in the social aspects of security monitoring system, China Telecom and China Netcom are comprehensively promote the "Global Eye" and "wide-visions" of the two carrier-class video surveillance systems, these monitoring systems are facing the front-end equipment, large-scale centralized access and large capacity storage needs. Previous stand-alone can not satisfy the storage capacity of these systems extend the application of flexible demand, to use a more advanced network storage devices and storage technology, including typical network storage SAN (storage area network), NAS (network access storage) and iSCSI
