Face search allows you to find faces similar to a given photo in the archive.

To perform face search:

  1. Set the search interval (see Setting a search interval).

  2. Set the minimum similarity level (in %) between the face in the photo and faces from the archive (1). The search results will contain only the video recordings with faces with similarity levels above the set value.  

  3. Select a photo with the face that should be found in the archive (2). Supported formats: png, jpg, jpeg, jpe. When you click the face in the surveillance window, this face will be selected for search. If you do not select a photo, then all faces recognized during the specified time will be displayed. To delete a photo from the search, click the button.

  4. Select, how to sort the search results: — by the similarity level; — by time (3).

  5. If necessary, set additional search criteria by clicking the button:

    1. Gender: select the required option;

    2. Age span: specify in years in the From and To fields.

      Note

      Saving information about gender and age to the database should be enabled in the detection tool settings (see Configuring Face detection).

      To delete a criterion, click the button.

  6. Click the Search button.

    Note

    Once launched, the search can be stopped at any time. To do this, click the Stop button which appears instead of the Search button.

This starts a search based on the defined criteria.

The video frames with the faces that meet the search conditions will be displayed in the search results panel. A recognized face will be highlighted with a red frame, and the face similarity level (in %) will be displayed below.

To instantly export a face image from the frame, do the following:

  1. Click a face track in the surveillance window.
  2. Click the button (4). 

The face image will be saved to the folder specified in the settings (see Configuring export options).
