VDS-2700 - Video and data over coaxial

VDS 2700 is the system for transmitting video, RS485 data, audio, alarm signals and DC power via a coaxial cable. This system ensures the quality of the transmission signal over a long or short distance. The distance can reach 600m when sending a DC power supply to the camera. Its duplex RS485 transmission channel is applied to the P / T / Z (pan / tilt / zoom) function of the PTZ dome camera. In addition to transmitting alarm and audio signals, the VDS 2700 also transmits DC power to the fast dome camera.

VDS 2700 consists of two parts. One is the remote unit, 2700-RU is connected to a fast dome camera (also called sender). The other is the local unit, 2700-L is connected to monitor with the monitoring system (also called
Viewer). Using interoperator technology, the VDS 2700 provides the innovative transmission method, fast installation with excellent image quality for a CCTV system.
