    Video Ground Loop Interference

    Joe calls from the county jail, he just finished installing 16 cameras for the jail and now that he has all the cameras up on the monitor there are small lines running through the screen on each camera.  His first thought is that there is defective equipment.  Either the CCTV cameras or the DVR are bad.  Neither is bad, the culprit here is video ground loop interference.
