This issue happens quite often on Zosi DVRs. The recorder randomly reboots by itself, sometimes two-three times a day, and for not any apparent reason.
In other cases, the DVR frequently stops working after booting up for a few minutes or just shuts down randomly. In this article, we’ll explain to diagnose and fix the Zosi DVR rebooting problem.
How to fix the Zosi recorder that reboots
There are many factors that cause a DVR to reboot, below are a few tips that can help you solve this issue.
Power adapter problem
The input voltage is not stable or too low and the DVR will automatically reboot. Make sure the power adapter is working fine and is able to provide the necessary power for the recorder.
Use only the power adapter and power cord that comes on the Zosi package. If you need to replace it, order one online with the same specs.
Damaged Hard Drive
A bad hard drive will draw more power from the motherboard and cause the whole DVR to reboot or shut off by itself. Make sure the hard drive is good.
Turn off the DVR, open up the top cover and disconnect the hard drive. See if the machine will continue to reboot without the hard drive. Also, check the cables (SATA and power cable), and ensure that there’s no damage. Use only CCTV surveillance-rated hard drives.
One of the cameras is causing short circuit
In jobs done poorly, the cameras may short circuit the DVR and damage the whole thing. Disconnect the cameras one by one and check if the rebooting issue persisted.
Also, check the power supply of the cameras, make sure the wiring is done correctly and there are no contacts between different wires.
Dust and dirt on the recorder
The dust may cause heating issues and the Zosi DVR will reboot in order to cool itself off. Open up the unit and make sure there’s no dust collected on the motherboard.
If your DVR is installed in any restaurant or kitchen area, the cooking smoke may cause condensation on the inside of the recorder. Double check to ensure everything looks good.
Update the firmware
Many of the DVRs manufactured by Zosi experience crashing problems. Out of nowhere the recorder crashes and reboots by itself.
This issue is related to firmware bugs. Update your recorder to the latest firmware. Make sure you flash the right firmware (contact your reseller to get the right firmware).
In this case, there’s not much to do, maybe the Zosi DVR you bought is faulty and no matter what you try it’ll still reboot randomly. Contact the seller, use your warranty and get a new replacement recorder from them.
