Using the access event generation, the Face-Intellect software allows obtaining real-time information on the number of passes of each person in the field of view of a given video camera.

Attention!

To use this function, you need to set the value of the registry key UseFaceDB = 2 (see the Registry keys reference guide).

The access event generation is enabled as follows:

  1. Go to the settings panel of the Face Recognition Server object.
  2. Select the Generating access event check box (1).
  3. Click Apply (2).

If the Generating access event check box is set, the Pass event (RECOGNITION_PASS) is generated when the face is detected. This event has the following parameters:

  • imageBase64 - contains jpg image from the camera in base64 format.
  • info - contains the following information sepearated by a semicolon (;): the names and identifiers of the cameras, that has ever captured the faces, and the number of passes.
  • total_passes - the total number of passes for the current recognized face.
  • age, gender - age and gender of the recognized person if the intellect.sec activation key allows the use of the age and gender recognition channel (see also Activation of the recognition modules in Face Intellect).
  • surname, name, patronymic, department, comment, sim - the parameters will be filled with corresponding values if the person is found in the online database.
  • firstId - the unique identifier of the captured face.
  • camera_id – the identifier of the camera that captured a face.

  • camera_name  – the name of the camera that captured a face.

These parameters can be used in scripts in the JScript programming language (for more information on creating scripts, see The Script object. Programming using the JScript language).
The following example shows the recording of a frame with a captured face image transmitted using the imageBase64 parameter to a file on the disk:

if (Event.SourceType == "FIRSERVER" && Event.Action == "RECOGNITION_PASS" && Event.SourceId=="1")
{
    SaveToFile("c:\\Faces\\"+Event.GetParam("firstId")+".jpg",Event.GetParam("imageBase64"),true);
}
