The Abandoned object detection can operate only with the basic Object tracker detection tool. |
To configure Abandoned Before you create and configure the Abandoned object detection, do as followsthe following:
- Create the Object tracker detection tool and set its general parameters (see Configuring Object Tracker).
- Configure some parameters of the Object Tracker detection tool as follows:
- Select the Object Tracker object (1).
To enable the Abandoned object detection (2), select Yes for the corresponding parameter.
In the Abandoned object detection sensitivity field (3), set the sensitivity for Abandoned object detection (2) andInfo title Note Objects abandoned for 10 seconds or longer will be detected.
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 (6). This value should be in the range [1, 100].Long-time abandoned object detection
In theInfo title Note This parameter depends on the lighting conditions and should be chosen empirically. It is recommended to select the parameter value starting from 20.
Yes If you enable this and the Enable filter parameter (see Configuring 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 field (4) specifyAlarm on object's max. idle time in area seconds. If60 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 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.
To enable the Auto sensitivity (5), select Yes for the corresponding parameter.

, select Yes for the corresponding parameter (6)Set the sensitivity for abandoned object detection and long-time abandoned object detection
in the range [1, 100].
Info title Note If you enable the Long-time abandoned object detection parameter (6) and the Neural network filter (see Setting general parameters of Tracker-based Scene Analytics detection tools), it can reduce the number of false positives during detection.
- Under the Object Tracker object, create the Abandoned object object (see Configuring detection tools and their sub-tools).
Select object class (2).
- Select object color (3).
Select object type (4):
Taken—the object that disappeared from the observed area and crossed its borders will be detected.
Abandoned—the object that appeared in the observed area and crossed its borders will be detected.
Any—both taken and abandoned objects will be detected.
Specify the maximum height and width of the object (5)This parameter depends on the lighting conditions and should be chosen empirically. It is recommended to select the parameter value starting from 20.
- Save the detection tool parameters by clicking the Apply
button.
To enable the Abandoned object detection sub-tool, do the following:
To create the Abandoned object detection, below the Object Tracker detection tool, click Create... → Abandoned Object.
By default, the detection tool is enabled and set to detect brought and abandoned objects.
If necessary, you can change the detection tool parameters. The list of parameters is given in the table:
| Parameter | Value | Description |
|---|---|---|
| Other | ||
| Enable | Yes | By default the detection tool is enabled. To disable it, specify No |
| No | ||
| Name | Abandoned Object | Enter a detection tool name or leave the default name |
| Type | Abandoned Object | Detection tool type name (non-editable field) |
| Basic settings | ||
| Maximum object height | 100 | Set the maximum height of the object that should trigger the detection tool, as a percentage of the frame size. The value should be in the range [0.05, 100] |
| Maximum object width | 100 | Set the maximum width of the object that should trigger the detection tool, as a percentage of the frame size. The value should be in the range [0.05, 100] |
| Minimum object height | 0,1 | Set the minimum height of the object that should trigger the detection tool, as a percentage of the frame size. The value should be in the range [0.05, 100] |

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