khawar 0 Posted February 12, 2011 I am also facing the same issue with a CCTV Setup. its giving lines on all the LCD Displays displays. also when it is connected with a TV having Sattelite receiver connected at one AV and DVR at the other AV it disturbes all the Display Screens with heaving lines moving from top to bottom. any one can support in this?

Soundy 1 Posted February 12, 2011 I split this into a new topic. Can you post some photos of the two kinds of interference? In the first instance, is it separate lines in each camera, or lines across the whole screen? Both cases sound like there's a ground-loop issue... Share this post Link to post Share on other sites
