How to crack the access control of residential property

The basic definition of access card The original intelligent access control system consists of a host, a card reader and an electronic lock (a computer and a communication converter are added when networking), and card reading is a non-contact card reading method.

Only when the cardholder quickly swings the card near the card reader (5- 15cm) can the card reader sense that there is a card and guide the information (card number) in the card to the host computer, which will first review the illegality of the card before deciding whether to close the door. As long as it is within the valid credit card category, all processes can realize the access control management function.

The card reader is installed on the side wall of the door and does not affect other work. And through the communication adapter (RS485) with the computer for real-time monitoring (all doors can be opened/closed by the computer, and the status of all doors can be viewed in real time), data solving, inquiry, report input, etc.
