detector.

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

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

Specify 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]

Parameter	Value	Description

Enable	Yes	The detection tool detector is enabled by default. To disable the detection tooldetector, select the the No value
Enable	No
Name	Hands up detection detector	Enter the detection tool detector name or leave the default name
Type	Hands up detection detector	Name of the detection tool detector type (non-editable field)
Basic settings
Event generation condition	Both hands	Select this value if you want the detection tool detector to generate an event only when a person has both hands raised
	One hand	Select this value if you want the detection tool detector to generate an event only when a person has either left or right hand raised
	Only left	Select this value if you want the detection tool detector to generate an event only when a person has one selected hand raised
	Only right
	Left hand	Select this value if you want the detection tool detector to generate an event only when a selected hand is raised
	Right hand
Number of measurements in a row to trigger detection	2	Specify the minimum number of frames with a person with a hand/hands raised for the detection tool detector to generate an event. The 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)	0.7

If necessary, you can configure the detection area. For this, do the following:

Click in the preview window.
Select Detection area.
Using the anchor points Image Added, set the detection area in which a person with both hands raised must be detected.

The Hands up detection works in the areas for detection and skip areas specified in the Pose Detection (see Configuring the Pose Detection).
