cctvman123 0 Posted April 25, 2017 I have a tvi hd dvr and had no problems with standard def cams. I just upgraded my SD cams to HD 2mp cams and I notice that randomly I see some of the cams suddenly switch from color to b/w. If I reboot the dvr all cams are in color but then gradually some just switch to b/w. I am running that pre-made bnc cable in various lengths no longer than 100 feet. I included a side by side picture of before and after. Could anyone possibility assist myself in trying to figure what it could be? Share this post Link to post Share on other sites
