If it shows abnormal, please try to format it again and we do recommend you save a backup of important clips before formatting by going to Advanced Settings > Export.

Meanwhile, please also check below information:

1. Please check the power adapter between the DVR and the cameras, the DVR should be 1A, and the camera should be 1.5A.

2. IP address conflict can also cause beeping, so please go to Device Management—Advanced Settings, and confirm whether your DVR IP address conflicts with the IP addresses of other network devices in your home, if it is, please disable the Enable DHCP button to modify the IP address of your DVR.

3. Please ensure the firmware of your system is updated to the latest by going to Device Management—Advanced Settings—Maintenance—Upgrade.

4. Unplug and plug the power adaptor again, after that, click the Shutdown button then choose the Reboot button to reboot your system.

5. You may also try to default the system by going to the Device Management—Advanced Settings—Maintenance—Default.
