cctvtec 0 Posted January 10, 2012 Get yourself a ground loop amplifier (humbug) it looks to me to be a ground imbalance. Basicly there is a voltage diference from where the camera is to where the dvr or monitor is. It could also be that your video cables are running alongside mains cables. stick a multi meter on the cable and see what voltage you get point to point (you should have around 1v) hope this helps Share this post Link to post Share on other sites
