to avoid interference the camera, monitor and dvr have to be energized from the same place ( a UPS maybe).

 

Sometimes it works for me to cut the earth connector on the monitors.

You are talking about earth loops which don't present as this type of interference. This looks like a scan fault on the camera sensor

Hi,

Im new to cctv and came across a job today where when the controller zooms in on a image the picture on the monitor goes black can anyone suggest what this could be. The image also has what looks like Interference.
