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:

  1. 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.
  2. 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:

  1. Power OFF the DVR / NVR.
  2. Disconnect the cameras from the back of the DVR / NVR.
  3. Power ON the DVR / NVR.

After powering the DVR / NVR ON, the system will stop restarting or continue restarting.

Follow the applicable steps below to continue troubleshooting.

IMPORTANT: Formatting the HDD will erase all data. Back up data before formatting.
