View Identification Events

Once a face detected, you will see a notification on the event list.

events_en

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 pause above the list of events.

When working with events, the following default filters may come in handy:

  • Dossier: display events only for a selected dossier.

  • Watch lists: display events only for a selected dossier category (watch list).

  • Acknowledged: display only acknowledged/unacknowledged events, or all events.

  • Cameras: display only events from a selected camera.

  • Camera groups: display only events from a selected group of cameras.

  • Start, End: display only events that occurred within a certain time period.

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: number of years age: 33
Gender Result: male/female (feature: gender): algorithm confidence in result female (gender): 0.95
Emotions Result: angry/disgust/fear/happy/sad/surprise/neutral (feature: emotions): algorithm confidence in result happy (emotions): 0.99
Glasses Result: eye/sun/none (feature: glasses): algorithm confidence in result none (glasses): 0.87
Beard Result: beard/none (feature: beard): algorithm confidence in result none (beard): 0.91
