Thanks for using our product and we’ll provide you with the best service.

The network video server is the equipment dedicated for real-time transmission of digital video and audio in

Ethernet. Adopting the programmable high-speed digital signal processor (DSP) specially designed for multi-media

processing, the network video server, which combines high-performance operation system and audio-video

compression algorithm, makes the image transmission more fluent and display more clear and smooth; in addition,

including the built-in WEB server, it can enhance the performance of traditional monitoring system, and provide the

network connectivity for issuing the monitoring images on a safe local area network or internet. The management,

configuration, monitoring and other functions of video camera can be operated easily through the Internet Explore.
