Video surveillance technology has gone through the analog, half digital, all-digital network HD several stages in our country since the 1980s, since the rise. Video at the same time intelligent video surveillance (IVS) technology is in out of the lab and into various application stage
With the development of Internet technology, IP-based video surveillance gradually been accepted, multiplexed transmission ip cameras compressed video information through the TCP / IP protocol to achieve video streaming technology online has authorized users can access to the Internet at any time, the command of the entire monitoring system, scheduling, storage, authorization control, and other functions. View of IPv6 in the quality of service, network performance, security improvements to improve the impact of IPv6 on next-generation Internet networks, IP-based video surveillance is mainstream. Network HD equipment occupy a dominant position in the video surveillance industry now, while in theory, any analog cameras, including fixed cameras, dome cameras with PTZ camera and so can be integrated into a network video system via video server equivalent to a combination of analog cameras and video servers, network cameras, there is currently a lot of manufacturers to produce the integration of ip cameras.
