6.4 Network Access and Remote Viewing
The NVR can be accessed remotely via a web browser or a dedicated mobile application (e.g., DMSS app). Ensure the NVR is connected to the internet and port forwarding or P2P (Peer-to-Peer) service is enabled for remote access. Refer to the NVR's network settings for details on P2P or DDNS configuration.
7. Maintenance
7.1 Regular Cleaning
Periodically clean the NVR's exterior with a soft, dry cloth. Ensure ventilation openings are free from dust and debris to maintain proper airflow.

7.3 Hard Drive Management
Regularly check the hard drive status in the NVR's system settings. If the hard drive is full, the NVR will typically overwrite the oldest recordings. Consider backing up important footage before it is overwritten.
8. Troubleshooting
This section addresses common issues you might encounter with your NVR.
- No Power:
Ensure the power adapter is securely connected to the NVR and the power outlet. Verify the power outlet is functional. Try a different power outlet.
- No Video Output on Monitor:
Check HDMI/VGA cable connections. Ensure the monitor is powered on and set to the correct input source. Try a different monitor or cable. If the NVR boots but shows no display, try restarting it.
- Cameras Not Displaying:
Verify that cameras are powered on and connected to the network. Check network cables. Ensure cameras have valid IP addresses and are added correctly to the NVR. Check camera compatibility with the NVR.
- No Recording:
Check if the hard drive is installed and initialized. Verify recording schedules are configured correctly. Ensure there is sufficient disk space. Check camera status; if a camera is offline, it cannot record.
