VDS - Video Modem System Poster

In the CCTV industry, almost all the cameras used coaxial cable to transmit the video and the other signals. Generally, when transmitting the video and the other signals over a long distance, there will be some interference appeared and the video quality will become weak. These are the degradation for the current coaxial cable application.

In order to solve such problems, we provide a most innovative product VDS to improve the video quality. Not only with video signals transmission, the VDS also can send the audio, alarm signals and RS485 data and camera DC power (12V or 24V) simultaneously, those are all through one single coaxial cable.

The application of VDS is used on the exist coaxial cable for CCTV camera system, the transmission distance can be easily reached to 500 meters ~ 1,000 meters, transmitting the video, audio, alarm signals, RS485 date and camera DC Power(12V or 24V). All the signal quality can be still remained in the best condition over a long distance transmission, which the method we used is by Multi-Carrier.

Currently, we have a wide range of VDS products as following for your selection:
