To search faces in the video archive, do the following:

  1. Upload an image for search (see Loading an image for search).

    Note

    The uploaded image is automatically verified with all faces in the reference face database and, if there is a match, then the name of the corresponding person and its similarity degree in percent are displayed on top of the uploaded image.

  2. From the Filter drop-down list (1), select the existing face search filter or enter an arbitrary filter name if the filter is supposed to be saved.
  3. From the drop-down list (2), select the required type of search interval:

    • Exact time—in the Period from and to fields, specify the beginning and end of the search interval in the DD.MM.YY HH:MM:SS format.

      Note

      The specified time period is not saved when the filter is saved.

    • Recently—in the Last field, specify the time period from the current time to the specified time. The following time units are available: Minutes, Hours, Days, Weeks, Months.

  4. In the Similarity level, no less than, % field (3), set the minimal similarity level between the reference face image and the captured face.

  5. Click the button (4) to specify the face characteristics:
    1. In the Camera field (1), specify the substring to filter out the cameras in the Cameras area (2).
    2. In the Minimum age and Maximum age fields (3), specify the minimum and maximum age of persons, respectively.

    3. In the area (4), set the checkboxes next to the corresponding face characteristics.

      Note

      Face characteristics (4) may not be displayed (see Configuring the additional face characteristics).

    4. In the Minimum temperature and maximum fields (5), specify the minimum and maximum face temperature, respectively.
    5. Click the OK button (6) to save the changes and return to the face search window.

  6. Click the button (5) to save this filter for the future use.

    Note

    To remove a filter, select it from the Filter drop-down list (1) and click the button (6).

  7. Set the Search for contacts checkbox (7) if it is necessary to find people who have been in contact with this person. The time, within which it is necessary to search for contacts, is set on the settings panel of the Face Recognition Server object (see Configuring the contact time with persons).
  8. Set the Display track checkbox (8) so that the movement (track) of a person is displayed as arrows on the Map interface object.
  9. From the drop-down list (9), select the method of the track display:
    1. Selected result—the map will display only the movement of a person corresponding to the selected line from the search result, i.e., the movement of a person from the object from which they came and to the object to which they went;
    2. Full page—the map will display the movement of a person within the specified page of the search results.
  10. Set the Add. info checkbox (10) so that the additional information (name, department, similarity, start time and end time) is also displayed near each arrow that shows the movement of a person on the map. The information that should be displayed is configured on the Map settings tab on the settings panel of the Face recognition and search interface object (see Map settings).
  11. Click the Search button (11).

Note

By default, one CPU core is used for face search. Using the CpuCoreCountSearch registry key, you can change the number of cores used (see Registry keys reference guide), which will increase search speed.

As a result, the selected face will be searched.
