In the other embodiment, the authorized personnel’s face is always kept within the viewing range as the trigger condition, and the trigger condition that the unauthorized personnel cannot detect is used as the triggering condition for the alarm, which not only ensures the safety of the authorized personnel, but also achieves the transmission of alarms to the outside world. Purpose of Information.

In a certain application scenario, the device also includes an access control device, as shown in FIG. 4, the access control device is connected to the face recognition device, and the face recognition device recognizes that the The face of the authorized person unlocks the access control device or unlocks the access control device after the set time has elapsed.

In the application scenario, as long as the face of the authorized person is recognized, the access control device will be opened after the set time, so that the unauthorized person will not notice any abnormality, thereby ensuring the safety of the authorized person. In addition, this embodiment can further lock the access control device after the preset delay time after the access control device is opened, which belongs to a normal and reasonable workflow and will not attract the attention of unauthorized personnel. , to further ensure property security.

The preset delay time can be preset according to the actual situation on site, for example, it can be set to 30 seconds.

Furthermore, in some application scenarios, the access control device includes a detection device, the detection device is connected to the access control device, and when the detection device detects that a person passes through the unlocked access control device, it locks the access control equipment. The access control device adopts the method of allowing only one person to pass through at a time of identification. In other words, if multiple people are required to pass through the access control device, only multiple face recognitions can be performed.

In one embodiment, the camera is an infrared camera. Infrared sensing is used to sense the temperature of each face within the viewing range. When the temperature is within the normal human body temperature range, it is judged that the face has biological signs; otherwise, it is judged that the face does not have biometrics. The face recognition device recognizes faces with biological signs, which can prevent illegal objects such as photos, videos, facial masks from being used as face recognition objects, and improve the security of recognition and monitoring.
