  1. Create the required detection tool and specify its parameters (see Configuring detection tools detectors and their sub-toolsdetectors).
  2. Below the created detection tool, click Create… → Exit From Area.

By default, the detection tool is enabled and triggers and set to generate events when an object leaves the detection area.

ParameterValueDescription

EnableYesThe detection tool is enabled by default. To disable the detection tool, select the No value
No
NameExit From AreaEnter the detection tool name or leave the default name
TypeExit From AreaName of the detection tool type (non-editable field)
Advanced settings
X-axis offset15Specify the X-axis and Y-axis offsets as a percentage of the track area to set receive events from the specified area of the detection tool triggering. The values must be in the range [1, 40]
Y-axis offset10
Basic settings
Event hold time (sec)2
Info
titleNote

The parameter is taken into account only if the Trigger on group of objects parameter is enabled.

This is the time period during which the detection tool waits for the next objects after the first object in the group is detected. If the specified number of objects (specified in the Number of alarm objects parameter) are detected within this time period, the detection tool triggersgenerates an event. If no additional objects are detected within the specified time period, the detection tool doesn't triggergenerate an event. 
Specify the time period in seconds when events will be held when responding to a group of objects. The value must be in the range [0, 86400]

Maximum object height100

Specify the maximum object height as a percentage of the frame size for the detection tool to trigger generate an event. The value must be in the range [0.05, 100]

Note
titleAttention!

The values of the maximum object height must be equal in the settings of the Object Tracker and Exit From Area.

Maximum object speed500

Specify the maximum object speed per second for the detection tool to trigger generate an event. The value must be in the range [0, 500]

Info
titleNote
  • In Axxon One, speed is a conditional value that is calculated using values of different dimensions. The speed calculation algorithm takes into account both the frame width and its height.
  • For a visual understanding of the speed values, we recommend specifying the speed when searching the archive (see Configuring minimum and maximum object speed).
Maximum object width100

Specify the maximum object width as a percentage of the frame size for the detection tool to trigger generate an event. The value must be in the range [0.05, 100]

Note
titleAttention!

The values of the maximum object width must be equal in the settings of the Object Tracker and Exit From Area.

Minimum object height0.1

Specify the minimum object height as a percentage of the frame size for the detection tool to trigger generate an event. The value must be in the range [0.05, 100]

Note
titleAttention!

The values of the minimum object height must be equal in the settings of the Object Tracker and Exit From Area.

Minimum object speed0

Specify the minimum object speed per second for the detection tool to trigger generate an event. The value must be in the range [0, 500]

Info

Minimum object width0.1

Specify the minimum object width as a percentage of the frame size for the detection tool to trigger generate an event. The value must be in the range [0.05, 100]

Note
titleAttention!

The values of the minimum object width must be equal in the settings of the Object Tracker and Exit From Area.

Number of alarm objects2
Info
titleNote

The parameter is taken into account only if the Trigger on group of objects parameter is enabled.

This number determines the minimum number of objects that are considered a group and can cause the detection tool triggering.  generate an event.
Specify the number of objects that can cause the detection tool triggeringto generate an event. The value must be in the range [1, 100]

Object classAll classes

Select the object class that must trigger the detection toolgenerate an event. The default value is All classes

Info
titleNote
  • When you create the Entrance In Area Exit From Area detection tool below the Object Tracker and select the Person value, the detection tool there won't trigger if it be any events if the tracker detects the movement of several people nearby.
  • When you create the Entrance In Area  Exit From Area detection tool below the Category: Face and Category: Vehicle detection tools, the Object class parameter must have the All classes value.
Vehicle
Person
Trigger on group of objectsYes

The parameter is disabled by default. If you want the detection tool to trigger generate an event only for a group of objects, select the Yes value

Info
titleNote
  • The group of objects that must cause the detection tool to trigger generate an event is specified in the Object class parameter.
  • The number of objects that is considered a group is specified in the Number of alarm objects parameter.
  • Waiting time for the next objects after the first object from the group is detected is specified in the Event hold time (sec) parameter.

For example, you select the Person object class, the Number of alarm objects is 23, the Event hold time (sec) is 2 seconds, and the Trigger on group of objects parameter is enabled. If the detection tool detects the first person and detects the others within two seconds, these people are considered a group and the detection tool will triggergenerates an event. 

No

By default, the entire frame is the detection area. In the preview window, you can specify the detection areas using the anchor points (see Configuring the Detection Zonea detection area).

Info
titleNote
  • For convenience of configuration, you can "freeze" the frame. Click the button. To cancel the action, click this button again.
  • The detection area is displayed by default. To hide it, click the button. To cancel the action, click this button again.
