satsuma01 Posted April 10, 2008 Share Posted April 10, 2008 sounds as though back light compensation is turned on, turn it off and see if that helps.

sjonley Posted April 11, 2008 Share Posted April 11, 2008 1. Turn off AGC (dip switch) 2. Adjust Iris level potentiometer on camera pcb 3. Make sure cable is terminated into 75ohm Is on the back of the monitor the termination switch set to High Z?

djandysp Posted April 11, 2008 Share Posted April 11, 2008 If you ask me AGC shouldnt be available on cams, it may enhance the signal strength on a night but any noise gets enhanced as well, if a picture is rubbish on a night then get some lighting Link to comment Share on other sites More sharing options...
