The work mould of access control
Add Time:2019-04-02
The access control is like a light switch. Short the circuit, give the motor a signal, open the door.
But this switch is like a lock. It can't be short-circuited without a key.
This key is different from the key of a general lock. It is intelligent. If there are times of wrong keys. The access control system will give an alarm. Moreover, the key has no basis to imitate and there is no universal key.
This key can be a fingerprint, a card, a password, a face, or many kinds of verification together.
The access control system is actually a micro-computer, which compares fingerprints, cards, passwords and faces. Only when it meets the requirements, can it be passed before it opens the door.
