To configure create the Stop In Areain area detector, do the following:

  1. Create the required
    2. detection tool
  2. detector and specify its parameters (
    3. see 
  3. see Configuring detectors and their sub-detectors).
  4. Below the created
    5. detection tool
  5. detector,
    6. click 
  6. click Create… → Stop
    7. In Area
  7. in area.

By default, the detection tool detector is enabled and set to generate events when an object stops moving in the area and remains stationary for a specified time.

Info
titleNote

Slight shaking of an object is allowed.

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

ParameterValueDescription
Other
EnableYesThe detection tool detector is enabled by default. To disable the detection tooldetector, select the the No value value
No
NameStop In Areain areaEnter the detection tool detector name or leave the default name
Event hold time (sec)2
Info
titleNote

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

This is the time period during which the detection tool detector waits for the next objects after the first object in the group is detected. If the specified number of objects (specified in the the Number of alarm objects parameter parameter) are detected within this time period, the detection tool detector generates an event. If no additional objects are detected within the specified time period, the detection tool 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]

Basic settings
Maximum object height100

Specify the maximum object height as a percentage of the frame size for the detection tool detector to 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 Stop In Areathe Object tracker and Stop in area.

Maximum object width100

Specify the maximum object width as a percentage of the frame size for the detection tool detector to 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 Stop In Areathe Object tracker and Stop in area.

Minimum object height0.1

Specify the minimum object height as a percentage of the frame size for the detection tool detector to 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 Stop In Areathe Object tracker and Stop in area.

Minimum object width0.1

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

Note

The values of the minimum object width must be equal in the settings of the Object Tracker and Stop In Areathe Object tracker and Stop in area.

Number of alarm objects2
Info
titleNote

The parameter is taken into account only if the the Trigger on group of objects parameter  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 detection tool detector to generate an event. The value must be in the range [1, 100]

Trigger on group of objectsYes

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

  • The number of objects that

  • Waiting time for the next objects after the first object from the group is detected is specified in
    • the 
  • the Event hold time (sec) parameter.

For example, you select the the Person object  object class, the Number of alarm objects is is 3, the Event hold time (sec) is is 2 seconds seconds, and the the Trigger on group of objects parameter is enabled. If the detection tool detector detects the first person and detects the others within two seconds, these people are considered a group, and the detection tool detector generates an event. 

No

By default, the entire frame is the a detection area. In If necessary, in the preview window, you can specify the detection areas using the anchor points Image Removed (see Configuring a detection can reduce the detection area (see Configuring a detection area) and/or set one or more skip areas (see Configuring a skip area).
