HD Network Video Recorder NVR

Why my security DVR/NVR keeps rebooting?

Your DVR/NVR uses the Linux-embedded OS, it should boot properly if it doesn’t encounter any hardware problem. However, all most DVRs/NVRs have been designed with fault detecting algorithm, if the recorder can not recognize the connected HDDs, it will keep rebooting.

Intending to check whether the reboot error has been caused by issues related to the HDD, you can disconnect HDD and boot recorder. If the recorder boots without HDD, then HDD is not recognizable or is not compatible.

Yet it’s unlikely the recorder can not recognize the HDD, you may try to re-connect the HDD and boot it again. Typically this will solve the problem. If the DVR/NVR still can not boot properly, please check the possibilities as below:

  • HDD is not compatible with the recorder.
  • Defective of HDD, then replace the HDD.
  • SATA cable is defective, replace the SATA cable.
  • The recorder connects to the wrong AC/DC power adapter (HDD requires sufficient current on the initial running).
  • If input voltage is not stable or it is too low, then change the power supply and cable.
  • CMOS button cell battery ran out, replace the CMOS battery on recorder’s motherboard.
  • The hardware malfunction, then replace it.

It should be noted that after went through strict test we listed these HDDs in the table, if your HDD doesn't appear in the list, it means the HDD model has not yet been tested by us, it doesn't necessarily mean it will not be compatible with the NVR. However, the NVR can't support 5400RPM HDDs e.g. WD Green HDD AADS can't support, its RPM is 5000.
