DVR / NVR: System continuously restarting
If the DVR / NVR is rebooting repeatedly, the issue may be caused by insufficient power or a hard disk drive (HDD) error. Check that the correct power adapter is in use and that the DVR / NVR is receiving sufficient power.
To check the power connection on the DVR / NVR:
- Plug the power adapter into a different power outlet. If the power adapter is connected to a surge protector or Uninterruptible Power Supply (UPS), disconnect and plug the power adapter directly to an power outlet.
- Ensure that the correct power adapter is being used for the DVR / NVR, and not the power adapter that is intended for a camera or Power over Ethernet (PoE) switch.
If the power connection is correct and restarting continues:
- Power OFF the DVR / NVR.
- Disconnect the cameras from the back of the DVR / NVR.
- Power ON the DVR / NVR.
