Cable transmission technology of the network camera The use of advanced video compression standard, at present, there are three mainstream compression formats, namely, JPEG, MPEG-4, H.264. Provide dual-stream support, at the same time of achieving HD local video, Dual-stream technology can reduce the bandwidth usage of the remote transmission and to ensure local good image quality. Improve the smart technology value-added, the smart technology can improve the efficiency of monitoring, and the value it can bring is more than that. Through preposition of coding and intelligent analysis, the built-in intelligence analysis module of high-definition network camera can grab from the source of valuable information and then spread to the background. It can reduce the transmission pressure, and truly realize effective transmission. Improve the front-end caching techniques. HD camera itself has limited data storage capacity. It depends on the communication transmission and back-end storage devices. We can design reasonable front-end caching mechanism to prevent loss of data in communication failure. Develop and comply with industry standards. Surveillance market manufacturers need to join together in elaborating the prevailing norms, seeking common ground while reserving differences on minor ones. Onvif, PSIA and some other organization for Standardization appears, people see the hope of the video products and systems standardization. APEXIS and other manufactures of IP camera have officially became members of the ONVIF standard protocols "Plug and play" era of video surveillance is not far off.
