View Identification Events
Once a face detected, you will see a notification on the event list.
A notification can feature different pieces of information, depending on whether a detected face has a match in the database:
Match not found: a normalized face image, detection date and time, the name of a camera group.
Match found: a normalized face image, the photo from a dossier, the name of a person, similarity between faces, the comment from a dossier, the name of a dossier list, detection date and time, the name of a camera group.
Note
You can configure the system in such a way that you will get notifications only for the faces with a match.
Important
In order to pause the notifications thread, click 
above the list of events.

Face Liveness and Face Features Recognition
Depending on the system settings, you can see an estimation of face liveness and/or a result of such face features recognition as gender, age, emotions, glasses, and/or beard.
The face liveness detector automatically spots fake faces and prevents photo attacks by distinguishing a live face from a face image.
Note
The liveness score can be null. It is so when the liveness detector is disabled or unable to estimate the face liveness in the provided image.
The face feature recognition result is in the following format:
Face feature |
Result format |
Example |
|---|---|---|
Age |
Feature: |
age: 33 |
Gender |

female (gender): 0.95 |
Emotions |

Glasses |

none (glasses): 0.87 |

Filter events by face features and liveness when needed.
