Brief Introduction to Face Recognition Access Control System
Currently, most access control systems rely on methods such as card swiping, fingerprint scanning, or password entry. However, these methods often lead to issues like lost cards or forgotten passwords, causing inconvenience in management and security. If a card or password is lost, it can be misused by others, posing significant security risks. In contrast, facial recognition access control systems effectively address these problems, providing a more convenient and secure solution for access management.
Inherent Advantages of Facial Recognition Technology: Non-contact identification not only makes usage more convenient but also reduces the risk of disease transmission since no physical contact with devices is required.
Solving Issues of Lost or Forgotten Access Cards: With facial recognition, individuals can enter and exit smoothly even if they forget to carry their cards or remember their passwords, eliminating the security risks associated with lost or forgotten cards.
Camera: Physical resolution should be no less than 3 million pixels, equipped with network communication interfaces to ensure lag-free video transmission.
Access Card Reader: A standard IC card reader serves as a backup method for opening doors.
Access Controller: Supports single-door control and is equipped with network communication interfaces.
Automatic Door Lock: An electronic magnetic lock ensures reliable door operation.
Server: A high-performance PC or server for processing and storing data.
Image Acquisition: Front-end video cameras continuously record, capturing relevant information when someone enters the camera's field of view and transmitting it to the facial recognition server.
Image Transmission: The image information captured by the camera is transmitted via the network to a switch, which then forwards it to the facial recognition server. Instructions from the server are also relayed through the switch to the access controller.
Face Database Creation: Images of VIP clients are imported into the face database on the facial recognition server, enabling shared VIP client information across different locations.
Face Comparison: The server compares the images captured by the front-end camera with those in the face database to verify identity.
Access Control: Upon receiving instructions from the server, the access controller converts them into electrical signals, disengaging the electromagnetic lock to open the door automatically. After the person enters, the electromagnetic lock re-engages, awaiting the next control signal.
Card Swiping for Entry: Card swiping serves as a backup method for facial recognition. If the system fails to successfully match a face, users can swipe their IC cards to open the door.
Record Querying: The system categorizes and stores images of all individuals who enter, supporting storage by time or other criteria, and provides query and search functionalities.
Facial recognition access control systems significantly optimize access management methods, achieving more intelligent and scientific access control, marking an important advancement in modern security management construction.
