It plays a major role in administrative management work such as work environment safety and personnel attendance management.
[0003] A kind of access control security monitoring device in the prior art is usually unable to adjust the recognition position of the recognition camera module after installation. More specifically, it is unable to adjust the optimal recognition shooting position of the camera by adjusting the appropriate angle and height position, and the camera usually cannot rotate, so there are certain limitations in recognition shooting, thus reducing the security of its security monitoring. At the same time, during long-term use, dust and impurities are easily attached to the surface of the camera, affecting its accurate collection of facial data, and further affecting the final facial recognition of the device. In response to the above problems, a solution is proposed below. Utility Model Content
