[0002] Access control refers to a system or device set up for the purpose of secure management and control of access to a place. It can effectively restrict people from entering and exiting a specific area, prevent illegal intrusion and improve security performance. The access control system includes multiple components, such as access control controller, access control card reader, access control lock, etc. The access control controller is the core equipment of the whole system, responsible for processing user information transmitted by the card reader and controlling the switch of the access control lock. The card reader is the interface between the access control system and the user. The user can authenticate the identity by swiping a card, password or fingerprint. The access control lock is generally installed on the door, and it can automatically unlock or lock according to the instructions of the controller.

The camera is used to capture the user's facial information. The camera has high definition and fast recognition capabilities, can accurately capture the user's facial features, and compare it with pre-stored information to achieve efficient face recognition. The fingerprint detection hole 9 is used to collect the user's fingerprint information. The introduction of the fingerprint detection hole 9 increases the diversity of access control recognition. The user can choose to use face recognition or fingerprint recognition to pass the access control, which improves the flexibility and convenience of use. The observation window 19 allows the user to observe the working status of the face recognition machine 8 from the outside. The design of the observation window 19 enables the user to understand the operation of the face recognition machine 8 in real time, thereby enhancing the transparency and credibility of use.

Stabilizing the fixing plate 4 with fixing bolts makes it easier to disassemble the fixing plate 4 later, thereby reducing the difficulty of maintenance of the device.

[0032] To sum up, compared with the related art, the present device can protect the face recognition machine 8 by setting a protective shell 5, effectively reducing the damage from the outside world, and can adjust the height of the protective door 14 by setting an electric guide rail 11. The height of the protective door 14 can be lowered during daily use when maintained by staff to display the area scene. At the same time, the protective door 14 can be raised at night when not in use to increase the protection effect. The limiting cylinder 15 cooperates with the limiting rod 16 and the adjustment plate 17 to ensure the protection effect after the height of the protective door 14 is raised.
