Object tracking allows a user to visually track the movement of objects in a camera's field of view or in a video recording in an archive.


Object Tracking is available if:

  1. the object tracker is activated for this camera (see Object Tracker);
  2. the Video Motion Detection tool is activated (see Settings Specific to Video Motion Detection);
  3. at least one of the Embedded Analytic tools is activated (see Configuring Built-In Detectors).

Object tracking performs the following functions:

  1. Recognizes the presence of a moving object and dynamically marks it with a transparent rectangle on the video image.
  2. Displays the trajectory of the object's movement.

Motion is detected based on the time gradient of the video image’s difference between frames.

To enable object tracking, select Show tracking in the viewing tile context menu.

Object tracking functions will now be activated.

To disable object tracking, click Hide tracking in the viewing tile context menu..

If you have created a situation analysis tool for this video camera (see Types of Situation Analysis Detection Tools), then you can see the detection parameters (areas, lines) in Live Video mode along with object tracking in the camera window.


Areas to be excluded from surveillance are outlined in dotted black and green line while detection areas are outlined in black and gray.

If an ANPR detection tool has been created for a camera, the license plates within the video image will be outlined (see Automatic Number Plate Recognition (ANPR)).


To ensure correct display of the outline, set the camera's Video Buffering parameter with the range of 500–1000 (see The Video Camera Object).
