In this chapter you can find information about the SmartFace information displayed in Nx Witness and also about how to configure this information .

Faces which are detected by SmartFace are displayed as Face objects in the Nx Witness VMS video items. The position of the face is tracked as it moves in the video, which enables Nx Witness to render bounding boxes around the detected faces.

All detected faces are automatically matched against all members saved in watchlists available in SmartFace. If the detected face is matched against a watch list member in SmartFace, then information about the watchlist name , watchlist member and the matching score is also displayed.

For an identified person Nx Witness displays the following attributes:

• Age – Estimated age

• Gender – Female or Male
  

• Face mask – Information if the detected person is wearing a mask

• Name – The name of the person who is saved as a watchlist member
  

• Id – ID of the watchlist member
  

• Watchlist – The name of the watchlist in which the detected person is stored as a watchlist member

• Score – The matching score of the detected face and the matched watchlist member

• IsSpoof - True or False (if spoof detection is configured).

Face preview in the Objects tab

To display the face attributes, select the Objects tab in the right pane. After that the face attributes are displayed in two locations – on the camera item, in the Overlay info and in the right panel, in the Objects tab. The difference between these views is that the Overlay info displays face attributes continuously from the obtained information, but the Object tab displays the first obtained face attributes and marks other information in brackets.
