Network video server is an embedded surveillance device designed for network application. It uses the most mature and high reliability exclusive DSP solution in the industry together with powerful RTOS operating system to actually realize industry grade MTBF (Mean Time Between Failure).Optimized H.264 video compression algorithm assures clearer and more fluent image transmission. Built-in Web Server allows users to conveniently carry out remote control via Internet Explorer. Furthermore, central management software can be used for integrated surveillance and management of multiple video servers, so it is very easy to build large video surveillance system.
