For example: it restarts around 7:30 every morning in the factory. The reason is that the strong electromagnetic interference from the factory will affect the normal operation of the host, which will crash the system.
For example: it restarts periodically from time to time. The reason is that the ambient strong electromagnetic interference from the activation of elevator and the transaction on ATM will affect the normal operation of the host, which will crash the system.
The problem can be solved only by improving the power supply, making the system well grounded or isolating digital video recorder system. In the whole system, single-point grounding for host computer should be adopted, and no multipoint grounding can be used, otherwise it will cause common-mode interference. Please ground the host of DVR through the ground screws at the rear side of body.
For the automatic restart caused by the host:
If it’s the failure of the hard disk, pull it out for testing.
If it’s the failure of the power supply, make replacement to confirm it.
If it’s the failure of the main board: 1. It restarts after the prompt of abnormal channel. 2. It restarts when it’s crashed after self-checking.
