To configure the Hands up detection, do the following:

  1. Create Pose Detection (see Configuring the Pose Detection).
  2. Below the Pose Detection, click Create… → Hands up detection.

By default, the Hands up detection generates an event if there is a person with both hands raised in a specified area.

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

Basic settings
Event generation conditionBoth handsSelect this value if you want the detection tool to generate an event only when a person has both hands raised
One handSelect this value if you want the detection tool to generate an event only when a person has either left or right hand raised
Only leftSelect this value if you want the detection tool to generate an event only when a person has one selected hand raised
Only right
Left handSelect this value if you want the detection tool to generate an event only when a selected hand is raised
Right hand
Number of measurements in a row to trigger detection2

Specify the minimum number of frames with a person with a hand/hands raised for the detection tool to generate an event. The value must be in the range [1, 20].
The recommended (default) value is 2.
Increasing the value can help eliminate false events, but increases the risk of skips. 
Decreasing the value can help reduce skips, but increases the probability of false events

Track retention time (sec)0.7Specify the time in seconds after which the object track is considered lost. This helps if objects in scene temporarily overlap each other. For example, when a larger vehicle completely blocks the smaller one from view. The value must be in the range [0.3, 1000]
  • The Hands up detection works in the areas for detection and skip areas specified in the Pose Detection (see Configuring the Pose Detection).
  • For convenience of configuration, you can "freeze" the frame. Click the button. To cancel the action, click this button again.
  • The area for detection 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.
