1. Create the Object tracker detector and set its general parameters (see Configuring the Object tracker).
2. Configure some parameters of the Object tracker detector as follows:
   

   Parameter	Value	Description
   Auto sensitivity	Yes	If auto sensitivity is enabled, sensitivity adjustments for moving and abandoned objects are not applied. To apply manual sensitivity adjustments, it is necessary to disable the auto sensitivity
   Long-time abandoned object detection	Yes	If you enable this and the Enable filter parameter (see Configuring the Object tracker), it can reduce the number of false positives during detection
   Abandoned object detection	Yes	Objects abandoned for 10 seconds or longer will be detected
   Alarm on object's max. idle time in area	60	Specify the time in seconds—if the object remains idle for the time longer than the specified, it will be detected. This value must be in the range [15, 1800]. Info title Note This parameter is used only for the Long-time abandoned object detection. It is recommended to select the parameter value starting from 15.
   Abandoned object detection sensitivity	20	For this parameter to work, it is necessary to first disable the Auto sensitivity parameter. Set the sensitivity for abandoned object detector and long-time abandoned object detection in the range [1, 100]. Info title Note This parameter depends on the lighting conditions and must be chosen empirically. It is recommended to select the parameter value starting from 20.

3. Save the detector parameters by clicking the Apply Image Removed Image Added button.

To create the Abandoned object detector, below the Object tracker detector, click Create... → Abandoned Object.
