Configuring the parameters

To create the Move from area to area detector, do the following:

  1. Create the required detector and specify its parameters (see Configuring detectors and their sub-detectors).
  2. Below the created detector, click Create… → Move from area to area.

By default, the detector is enabled and set to generate events when an object leaves one area and enters another area.

If necessary, you can change the detector parameters. The list of parameters is given in the table:

ParameterValueDescription
Other
EnableYesThe detector is enabled by default. To disable the detector, select the No value
No
NameMove from area to areaEnter the detector name or leave the default name
TypeMove from area to areaName of the detector type (non-editable field)
Advanced settings
X-axis offset15Specify the X-axis and Y-axis offsets as a percentage of the track area to receive events from the specified area. The values must be in the range [1, 40]
Y-axis offset10
Event duration for detection triggering (sec)0Specify the maximum duration of an event in seconds for the detector to generate an event. The value must be in the range [0, 172800]
Time detection modeLonger than specified timeSelect the mode for determining the time it takes for an object to move from one area to another. The default value is Longer than specified time. If you select Less than specified time, the Event duration for detection triggering (sec) parameter must be greater than 0
Less than specified time
Basic settings
Event hold time (sec)2

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 detector 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 detector generates an event. If no additional objects are detected within the specified time period, the detector doesn't generate 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 detector to generate an event. The value must be in the range [0.05, 100]

The values of the maximum object height must be equal in the settings of the Object tracker and Move from area to area.

Maximum object width100

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

The values of the maximum object width must be equal in the settings of the Object tracker and Move from area to area.

Maximum speed500

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

  • 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).
Minimum object height0.1

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

The values of the minimum object height must be equal in the settings of the Object tracker and Move from area to area.

Minimum object width0.1

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

The values of the minimum object width must be equal in the settings of the Object tracker and Move from area to area.

 

Minimum speed0

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

  • 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).
Number of alarm objects2

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 generate an event.
Specify the number of objects that can cause the detector to generate an event. The value must be in the range [1, 100]

Object classAll classes

Select the object class that must generate an event. The default value is All classes

  • When you create the Move from area to area detector as a child object of the Object tracker and select the Person value, there won't be any events if the tracker detects the movement of several people nearby.
  • When you create the Move from area to area detector as a child object of the Category: Vehicle detectors, 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 detector to generate an event only for a group of objects, select the Yes value

  • The group of objects that must generate an event is specified in the Object class parameter.
  • The number of objects that are 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 3, the Event hold time (sec) is 2 seconds, and the Trigger on group of objects parameter is enabled. If the detector detects the first person and detects others within two seconds, these people are considered a group, and the detector generates an event.

Configuring detection areas

To configure detection areas, do the following:

  1. In the preview window, specify two areas. The detector generates an event if any object moves from one area to the other in the specified direction.
    By default, the areas are located on the right side and the left side of the video image. The anchor points of each area are connected by a two-color dotted line. You can resize the area by dragging its anchor points . To move the entire area, left-click and drag its border. To add anchor points, click . 
  2. In the preview window, specify the directions of the object movement. The direction of movement between the areas is indicated by a dotted arrow. To change the direction of movement, click  on the direction arrow. The available directions are:
    1. Left.
    2. Right.
    3. Both directions.
  3. Click the Apply button. To cancel the changes, click the Cancel button.
  • 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.

Configuration of the Move from area to area detector is complete.
