Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No video output on monitor | Loose HDMI/VGA cable, incorrect input selected on monitor, NVR not powered on. | Check cable connections. Ensure monitor is set to the correct input source. Verify NVR power. |
| Cameras not displaying | Network issue, camera not powered, incorrect camera IP address, camera not added to NVR. | Check network cables and connections. Verify camera power. Ensure camera IP is correct and added to NVR. Check firewall settings. |
| No recording | HDD not initialized, no recording schedule, HDD full, HDD failure. | Initialize HDDs. Configure recording schedules. Check HDD status and free space. Replace faulty HDDs. |
| Remote access not working | Network configuration issues, incorrect port forwarding, firewall blocking. | Verify NVR network settings. Check router port forwarding rules. Disable firewall temporarily for testing. Ensure P2P service is enabled if used. |
