The icon of object type and track lifespan (in seconds) can be displayed in the surveillance window on the layout.

To display the track lifespan in the surveillance window:

1. In the settings of the required detector:

   • Select the Yes value in the Track lifespan parameter.
   • Select the detection area.
   • Save changes.
2. Go to the required layout (see Configuring layouts).

3. In the surveillance window of the required camera, open the context menu.

4. Select Show detector data.
   

   If you created several detectors for the camera, the name of the menu item changes to Detector data. In this case, hover the mouse cursor over Detector data and set the checkbox next to the required detector.

   
   

As a result, the object is outlined in the surveillance window. The outline displays:

• Icon of object type (for example, vehicle, person, face).
• Track lifespan (in seconds).
