Thanks Toss ~ apologies for my lack of technical expertise in detailing my problem.....
I have 2 cameras .
On the monitor when selecting Camera 1 it has camera 2's image "ghost" like, translucent, scrolling across my monitor right to left.

The cameras + DVR were bought part of a kit, all matched i have added nothing.
The cable is cat5e with baluns. i have checked and double checked termination.

Would a BNC Ground Loop Isolator between camera and dvr be beneficial ?
