】
After being turned on, the device will alarm when it detects a face

It consists of Ordinary capture, Face library capture, and Non-face library

【
Face contrast recognition threshold

requirement is to track the face and face database. If the threshold is set to 100, the
tracking face must be 100% similar to a picture in the face database to be recognized and
displayed on the OSD.
