Unable to open surveillance camera matching.

What you want to ask is what if the camera match can't be opened? The specific operation is as follows:

It can be concluded that your problem is that the interface is loose, usually the graphics card is loose. You can take the graphics card down and put it back, which will usually solve the problem.

Your memory can't be loose. You can remove the memory (without installing it) and open it. If there is an alarm, there is something wrong with the memory. You can usually solve this problem by reloading the memory.

Another situation is that your motherboard is deformed, that is, you take down the memory and turn it on without giving an alarm. You can try to loosen the motherboard gong line, gently move the motherboard up and down twice, and then install the memory graphics card, which will generally solve the problem.
