Description

Technical Field

[0001] The present invention relates to the technical field of access control identification, and in particular to an access control identification device and a use method thereof. Background Art

[0002] With the advancement of technology, access control machines have evolved from the traditional unlocking method of entering a password and swiping a card to face recognition. Access control machines with face recognition function use cameras to collect facial features of the user to be authenticated, and open the door by comparing the collected portrait image with the stored face database data. Cameras with face recognition function are also used to obtain facial information of outsiders.

[0003] The open-air access control recognition devices currently used at the entrances of most communities do provide owners with a convenient entry and exit experience in clear weather. However, when it rains, water droplets will adhere to the surface of the access control recognition device and mix with the dust on its surface to form a layer of obscuration. This not only greatly reduces the clarity of the display screen, but also seriously interferes with the camera's ability to accurately capture the owner's facial features, thereby causing access control response delays and bringing unnecessary troubles and inconveniences to the owner's daily travel.
