8.2 Setting Face Recognition
When a face is detected or recognized in the detection area, the system performs alarm linkage
and supports searching face detection and recognition results.
● Face Detection: When a face is detected in the area, the system performs alarm linkage,
such as recording and sending emails.
● Face Recognition: When a face is detected in the area, the system compares the captured
face image with the information in the face database, and links alarm according to the
comparison result.
For the process of setting face recognition, see Figure 8-5.
