Install five cameras, and you can fully monitor.

You can buy a camera for tens of dollars. Just try it. If you feel unclear, you can buy a new one. Generally speaking, the anti-theft device does not need to be equipped too high. Besides buying cameras, you should also buy shunt lines and long wires. You can try to install one on the USB interface first, and then you will know how long it will take. If one meter is five yuan, it should be more than two hundred yuan.

The easiest way is to connect the USB interface. When recording, after the software is installed on the computer, there is the word "monitoring". Just check the box above, such as when to call the police and what ringtone to use for the alarm.

128 memory or more, if it is dedicated, if it is a computer and has other uses, it is 256 memory. The capacity can be 40G or 80G, which should be cleaned at any time.

Pay attention to debugging at any time. If the picture is not clear or blocked by something, pay attention to whether the thief did it on purpose.

In addition, the camera can also be installed with more than 36 volts of alternating current. If a thief steals a camera, he can catch it red-handed and hand it over to the public security organ.
