tomcctv 190 Posted March 7, 2018 Hi firmware would not help you ...... if unit was working Have you changed the video format on each channel? On each camera screen there are icons bottom left....... you need to click on the last one. Till the format is displayed ... click then it shows cvi click again it shows tvi click again and it shows AHD click again and it show analog But each time you change it wait 10 seconds before you click again Just do it on one camera if that fixed it then do the rest Share this post Link to post Share on other sites
