To configure the confidence threshold for face verification and automatic events/episodes cleanup, navigate to the Preferences tab. Click General. After you are finished, click Update.
In this section:
FindFace Security verifies that a detected face and some face from the dossiers belong to the same person (i. e. the faces match), based on the pre-defined similarity threshold. The default threshold is set to 0.75 which can be considered as optimum. If necessary, you can change the threshold.
The higher is the threshold, the less are chances that a wrong person will be positively verified, however, some valid photos may also fail verification.
