This building surveillance project uses 14 pairs of video server (SED-2100R) and Transcoder (SED-3200) for solving connection problem. Since the security guards are used to operate the original DVR system or to use control panel to control PTZ camera. However, there are totally 7 camera installation sites. The distance between each camera installation site and control center is around 140M. It would be highly difficult to install coaxial cable. Furthermore, because of the existed network system, IP transmitting method would be the best solution for this project. Each channel only needs 3Mbps and transmits through internet. But the video quality is the same as analogue system.
