If you do not get any video signal after switching the video cable, power cable, and power supply, you most likely have a bad camera.If you are using a test monitor that does not have power output, I suggest that you use a spare CCTV camera power supply to temporarily power the camera.The MON-7HD test monitor in the above image includes a short power jumper cable used to connect your camera’s power input. If you have a test monitor that can supply power to your camera, connect the power output of the monitor to your camera. If you do not get a video signal, disconnect the power cable from your camera.Disconnect the video cable from your camera and use a short RG59 BNC jumper cable to connect the video output of the camera to the BNC input of the test monitor. If your camera is already mounted and connected to a power supply, I recommend that you first only connect the camera’s video to the input of the test monitor.Here are the steps that I recommend if you are going to use a test monitor to troubleshoot. Many CCTV testers, like the one above, have a 12V DC power output that can be used to supply power to your camera. Using a test monitor, you can temporarily eliminate the power and video cable that your camera is using. ![]() ![]() One of the most common problems when a camera is not displaying video is a bad cable or BNC connection. Using a test monitor is one way to do this.Ī CCTV test monitor is extremely helpful when troubleshooting camera video issues. If you have confirmed that your power supply is working properly and that the ports on your DVR are also working properly, the next step would be to determine if you have a bad power or video cable. If the troubled camera works and the camera that was working does not work, then you have a bad input port on your DVR. Does the working camera show video on the other BNC port? Does the troubled camera display video on the other port? Plug the BNC connector of the camera that is working into the port of the camera that is not working. Simply disconnect the BNC video connector of the troubled surveillance camera from the back of your digital video recorder and plug it into one of the ports where a working camera is plugged in. It is a simple thing to test, so you may as well give it a try before you spend time on the other troubleshooting steps. This is uncommon, but it is possible that one of the BNC video input ports on your DVR went bad.
