If you are experiencing video loss with one of your DVR cameras, perform the following troubleshooting steps to identify if the VIDEO INPUT port (channel) is faulty.
How to test
- As per image above, swap CH1 (port having Video Loss issue) and CH2 (known working port).
- Check the "Video Loss" error again.
- If "Video Loss" remains on the same channel, then the VIDEO INPUT port of that channel (CH1) is faulty.
- If "Video Loss" changes to the other channel (CH2), then it's possible that either the BNC extension cable or the camera is faulty.
TIP: If the above troubleshooting did fix the issue, proceed with Power Adapter (PSU) swap and then BNC extension cable swap to further isolate the Video Loss problem.
