Create a face recognition template:

  1. Face recognition is used in multi - person motion scenarios to avoid incorrect recognition of the human body template when a person leaves the venue and enters again.
  2. First, enable the face recognition function in the recording settings, select "Record", and have the model stand in front of the first camera (the first camera is the one displayed first in the view after opening the reference video). Face the camera directly to ensure that the face is clearly visible, and there must be only one face. After clicking "Record" and checking that the image is correct, a pop - up window will appear asking you to enter the face name.

  1. When the human body leaves the venue and enters the venue again, it needs to face the first camera within the view of all cameras, and it must ensure that there is only one face for human body template recognition.
warning

If there is only one human body with white dots in the venue and only one template is selected in the assets, there is no need for face recognition, and it will be directly recognized as that template. In other cases, it will be matched according to the template of the bound face name. When face matching, the face is required to face the camera directly, and only one person fails to match the template.
