Be sure to use a dedicated surveillance drive. They will not work if you use regular desktop hard disk drives. Important note: DVRs and NVRs work best with dedicated surveillance drives. If there is more than one hard drive installed in the DVR / NVR, they need to be unplugged one by one to identify which one is causing the rebooting problem. If the problem stops, there is a need to replace the faulty hard drive. Carefully unplug the HDD from any connections to the system board and test if the rebooting continues (there are 2 connections, one is the data connection and one is the power connection). ![]() To check the HDD you will need to power off the device and open it up. Another potential problem is that a damaged hard drive draws more power than needed from the motherboard and may cause the recorder to shut down. Many DVRs have a fault detecting algorithm, if the recorder can’t recognize the connected HDDs, it will keep rebooting. If the problem stops, then the HDD is the problem. If the DVR continues to reboot automatically, continue with the other steps in this check list.Ī faulty HDD can cause the DVR / NVR to reboot, a simple way to check if the HDD is the cause of the problem is by disconnecting it from the system board. By unplugging the cameras, monitors or anything else plugged to the DVR and then re-connecting them one by one you can determine if this is the source of the problem. If the cameras are installed near high voltage, the system can detect incoming voltage and restart to protect itself (This problem is common with HD Analog CCTV using coaxial cables). Sometimes, the cameras might cause a short circuit. Power off the DVR, then Disconnect the DVR from any cameras and power it on again and check if the problem continues. It is also advisable to double check the outlet the device is connected to: This is easy to do by plugging the DVR to another outlet and seeing if the problem persists. ![]() For testing purposes, unplug the device from any battery backup power like surge protectors or UPS.Ĭheck the device power adapter: make sure you are using the right adapter that can provide enough power for the DVR and that it is intact (make sure it is not the power adapter that is intended for a camera or Power over Ethernet (PoE) switch). When the voltage is unstable or lower than standard values, it can cause the DVR to restart automatically. ![]()
