5. Maintenance

5.1 Hard Drive Management

Regularly check the hard drive status through the DVR's OSD menu. If the hard drive becomes full, the DVR will typically overwrite the oldest footage. You can configure this behavior in the recording settings.

5.2 Firmware Updates

Periodically check the Amcrest website for firmware updates. Keeping your DVR's firmware up-to-date ensures optimal performance, security, and access to new features. Follow the instructions provided with the firmware update package carefully.

5.3 Cleaning

Clean the exterior of the DVR with a soft, dry cloth. Do not use liquid cleaners or aerosols, as they may damage the internal components.

6. Troubleshooting

6.1 No Video Output

• Ensure the DVR is powered on and the power indicator LED is lit.
• Check HDMI/VGA cable connections to both the DVR and the monitor.
• Verify the monitor input source is correctly selected (HDMI/VGA).
