Tip

Camera Video stream and scene requirements for the Object Tracker and its sub-tools

...

  1. Create the Object tracker detection tool and set its general parameters (see Configuring the Object Tracker).
  2. Configure some parameters of the Object Tracker detection tool as follows:
    ParameterValueDescription
    Auto sensitivityYesIf 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 detectionYesIf 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 detectionYesObjects abandoned for 10 seconds or longer will be detected
    Alarm on object's max. idle time in area60

    Specify the time in seconds—if the object remains idle for the time longer than the specified, it will be detected. This value should be in the range [15, 1800].

    Info
    titleNote

    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 sensitivity20

    For this parameter to work, it is necessary to first disable the Auto sensitivity parameter.

    Set the sensitivity for abandoned object detection and long-time abandoned object detection in the range [1, 100].

    Info
    titleNote

    This parameter depends on the lighting conditions and should be chosen empirically. It is recommended to select the parameter value starting from 20.


  3. Save the detection tool parameters by clicking the Apply button.

Note
titleAttention!

In the settings of the Object tracker detection tool and the Abandoned object sub-tool, the values of the maximum and minimum height and width of the object should be equal.

Object type

BroughtSelect a value if it is necessary to detect an object that has disappeared from the observed area and crossed its boundaries
Abandoned
Any

Select this value if it is necessary to detect both brought and abandoned objects

By default, the entire frame is a detection area. If necessary, in the preview window, set detection areas with the help of anchor points  (seeConfiguring the Detection Zonea detection area).
