These Video Noise Suppressors are passive devices designed to reduce interference in Security Camera CCTV signals, they are easily installed in new or added to existing systems. They are particularly useful where a video signal is transmitted between points with different ground potentials.

 

Choke-V++ Video Interference Suppressor should be installed where runs of Video Cable are known to have ground loops, it should be fitted at the Security Camera Video Output before it is connected to anything else.

 
If there are several Security Video Cameras in a system located in an area with a ground loop problem, Video Chokes should be fitted to all Cameras to break the ground loop otherwise interference may continue.
