The community door is already automatic, why do you need security?

It is normal that the gate sometimes opens automatically and sometimes safely. First of all, we need to understand the working principle of the gate. Because the gates are all controlled by computers, the computer box of each gate will be directly connected to the security room and connected with a manual switch, which is also a switch set for the convenience of car owners without Bluetooth remote control or foreign vehicles, or car owners with remote control. Therefore, if it is a residential area, the property management company will generally send a Bluetooth remote control to the owners with parking spaces. As long as the owner passes the road brake, the Bluetooth remote controller will automatically turn on the display frequency on the computer box next to the road brake. If the remote control is out of order or broken, the general security guard will turn it on through the switch or the remote control of the property.
