tube tech 1 Posted August 17, 2017 you have a ground loop. you can read many tutorials on the subject and remain unclear on what that means. try an isolation transformer on that input. try that camera on a different DVR. try that camera direct into a monitor. try feeding that camera directly into a DC powered monitor with no connection to the system.

DON Mc 0 Posted August 22, 2017 It does look like you have a ground loop. There are several articles on this website that explain the different ways a ground loop gets into your video signal, and how to get rid of them. Go to FMSYSTEMS-INC.com and click on the Publications, Technical Publications, then use the search box using ground loop as a key word. You will get all the information you need about ground loops and how to get rid of them. Share this post Link to post Share on other sites
bentech 1 Posted August 24, 2017 OK tks... Is it possible that the signal is not strong enough ? Share this post Link to post Share on other sites
