dave1814 0 Posted January 14, 2011 Hi guys, We have a problem with our cctv system which has stumped us for quite some time now. Originally we had 4 cams connected using a AverMedia NV3000 card, we have decided we needed more cameras and got another NV3000 card which was installed in the PC. It seems now that if we have more than one card we get a crosshatch pattern forming on the cameras every few minutes or so, e.g... If we take out any one of the cards the problem does not occur again. Has anyone ever experienced this issue before? We have replaced all the connections to the card and also tried a new PC! Many thanks, Dave Share this post Link to post Share on other sites
