That appears to be a power related distortion, hum, to me. You could try a large ferrite bead style choke on the problem camera's power and/or video cables. Alternately, ditch the analogs and replace with digital, IP, based cameras and be done with it. I'd also change the clear camera angle to get that light out of the frame on the lower left of frame.

Hi Qualitech

Test with a new cat6 cable and appropriate connectors .. could be various issues .. this is why I always like to have an extra cable around to test with ..

Same idea, different implementation. May work better, then again maybe not. YMMV.
