To configure the Multiple Objects, do the following:

  1. Create the required detection tool and specify its parameters (see Creating detection tools).
  2. Below the created detection tool, click Create… → Multiple Objects.

By default, the detection tool is enabled and triggers when the number of objects in the detection area exceeds the value specified in the detection tool settings.

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

ParameterValueDescription
Other
EnableYesThe detection tool is enabled by default. To disable the detection tool, select the No value
No
NameMultiple ObjectsEnter the detection tool name or leave the default name
TypeMultiple ObjectsName of the detection tool type (non-editable field)
Basic settings
Maximum object height100

Specify the maximum object height as a percentage of the frame size for the detection tool to trigger. 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 Multiple Objects.

Maximum object speed500

Specify the maximum object speed per second for the detection tool to trigger. 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).
Maximum object width100

Specify the maximum object width as a percentage of the frame size for the detection tool to trigger. 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 Multiple Objects.

Minimum object height0.1

Specify the minimum object height as a percentage of the frame size for the detection tool to trigger. 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 Multiple Objects.

Minimum object speed0

Specify the minimum object speed per second for the detection tool to trigger. 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 width0.1

Specify the minimum object width as a percentage of the frame size for the detection tool to trigger. 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 Multiple Objects.

Number of alarm objects10

Specify the number of objects for the detection tool to trigger. The value must be in the range [1, 100].
When the specified number of objects is exceeded, the detection tool generates the Triggering start event. When the number of objects becomes less than the specified value, the Triggering end event is generated.

Object classAll classes

Select the object class that must trigger the detection tool. The default value is All classes.

  • When you create the Entrance In Area detection tool below the Object Tracker and select the Person value, the detection tool won't trigger if it detects the movement of several people nearby.
  • When you create the Entrance In Area detection tool below the Category: Vehicle detection tools, the Object class parameter must have the All classes value.

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 Zone).

  • 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.

To save the parameters of the detection tool, click the Apply  button. To cancel the changes, click the Cancel  button.
