RGB Lines randomly appear on my security cameras?

[bmw1999m3 0]

Hi, does anyone know why my security camera images sometimes get these Red/Green/Blue lines?

 

Unplugging the power to the camera and plugging it back in solves the problem.

The connection doesn't seem corroded, voltage always tests fine. Why does this happen?

 

Sometimes I can go weeks without seeing the RGB lines, sometimes it happens every 1-2 days. It seems to happen after the camera switches from color to Black/White mode. I've seen it only happen to specific cameras. It's not a problem that jumps around to other cameras.

 

Thanks in advance.

A couple of things can cause this.

First check all your connections.

Second (i had this issue) if all of your wires in the back of your DVR are zipped tied together just a liitle too tight this may cause your issue. I removed the first zip tie closest to my dvr and it solved my issue with 1 cam i was having.

 

Another thing are you cam wires too close to any 240v wiring in your home?? That can cause interference as well.
