If you are experiencing video loss with one of your DVR cameras, perform the following troubleshooting steps to identify whether the issue lies with the camera or the cable.
NOTE: If the camera that has video is already mounted, first unmount the camera for proper troubleshooting. Use a spare and working extension BNC cable if available.
How to test
- Connect the camera having Video Loss issue to a known working channel of your DVR.
- If using a spare extension BNC cable, first disconnect a known working channel from the back of your DVR and replace it with your spare BNC cable then connect the camera having Video Loss to the other end of the BNC cable as per image above.
- If a spare BNC cable is not available, use the other working channel instead. Unplug the functioning camera from the other end of the BNC cable and connect the camera experiencing "Video Loss".
- Check if the "Video Loss" error appears on the channel of that camera.
- If "Video Loss" appears, then the camera is faulty.
- If the unmounted camera works, then the BNC cable connected to the camera experiencing "Video Loss" is faulty.
TIP: If the above troubleshooting did not fix the issue, perform the Power Adapter (PSU) swap and BNC extension cable swap to further isolate the Video Loss problem.
