1. If a large number of cameras are disconnected, how to eliminate the fault?

If the cameras with a large number of installed cameras are disconnected, observe whether only one of them is disconnected, or they are disconnected indiscriminately, or several of them on a switch are disconnected. If only one of them is frequently disconnected, there may be a problem with the machine. You can upgrade or restore the system and try it; If the switch fails from time to time, it is due to insufficient switch resources. The monitoring project recommends replacing the Gigabit switch. If several switches on a switch fail together, the problems of switch and line should be considered.

2. What are the precautions when accessing the front-end IPC?

For places with small monitoring area, when only 2-3 IPC are installed, customers prefer to connect directly to the router, and then install software on the computer to display. It is not recommended to use more than 3 IPC for computer display.

It is not recommended to fully load the video recorder in the monitoring project. First, it is afraid to occupy too many resources of the video recorder. Second, in case the user wants to increase it in the future, if it is fully connected before, the back-end equipment needs to be replaced to avoid waste. Of course, these need to be explained to the customer in advance. In terms of storage, I prefer to monitor the special hard disk. Now the price of the monitoring special disk is almost the same as that of the mechanical disk of the desktop computer. The special disk is more stable, and the warranty time is more than one year. Why not.
