hobbeze 0 Posted October 10, 2012 Hi, have a H264 DVR with 16 cameras connected. 4 cameras are showing "Video Loss". Checked all the connections and even took a working camera and put it in each input. Working camera worked in all inputs but the malfunctioning cameras do not work in any input. Is this more likely an issue with the cameras or the cables? Thanks. Share this post Link to post Share on other sites
the toss 0 Posted October 10, 2012 Ok - you've proved the recorder channels are working. Replace the suspect camera with a working one & you will prove the problem to either the cable/connectors or the camera itself Share this post Link to post Share on other sites

hobbeze 0 Posted October 17, 2012 Thanks, it ended up being a power supply problem. An entire relay box had come unplugged. Share this post Link to post Share on other sites
