Our community said to install intelligent access control system. What is that?

This is a security system. To put it bluntly, it is to put something on the door. If you want to go in and out, especially when you enter the door, you need to swipe your card or fingerprint and head. Of course, there are many cards in the community, and the card is given to you by the property. You need to swipe your card when you enter the door. Usually the door is locked, so you can't get in without a card. If you go out, you can check it and press a button to open the door. Mainly to prevent non-local owners from entering and leaving, for safety.
