VST_Man 1 Posted December 9, 2006 what kind of DVR is this? I've seen this on power supplies. camera's, and on DVR's. Try the simple things first; - ground both camera's and DVR on same wire(s) do not add any special grounding on the camera's, just make sure the power supply and DVR are on the same power strip/UPS. - make sure the RG connectors are seperated and not touching in any way. - disconnect one camera at a time to see if the problem goes away.if it does that camera is causing the "inbalance". - isolate the camer power with single powersupplies. connect the single to the camera with the fluctuation and see if that corrects it. - monitor the camera input with a seperate video monitor.is it clean? - ground loop meter? if you have one use it to see if your getting any GL "noise" on the cables. Happy hunting.............. Share this post Link to post Share on other sites
