Description

Technical Field

[0002] Facial recognition is an emerging biometric technology and a high-tech technology that is being tackled in the international scientific and technological field today. In situations where security needs are relatively high, the combination of monitoring and facial recognition will be more effective and can prevent strangers from entering. Therefore, security monitoring devices with facial recognition functions are becoming more and more popular.

[0003] For example, the security monitoring device with face recognition function with the authorization announcement number "CN220570591U" combines face recognition with monitoring and voice prompts, and can track, monitor and alarm people who are not in the database. The monitoring camera, face recognition device and voice player are connected together and rotate synchronously to facilitate tracking. However, the security monitoring device with face recognition function can only adjust the front and back direction of the camera, but not the left and right direction of the camera, so that the camera's irradiation range is narrow, which increases the limitation of work. At the same time, when the security monitoring device with face recognition function needs to repair the camera, the operator needs to turn multiple bolts to remove the mounting plate. Turning multiple bolts takes a long time to remove the mounting plate, which reduces work efficiency. Utility Model Content
