When configuring the Multiple objects detection tool, you should set the maximum number of objects within the analyzed zone. Exceeding this number leads to triggering the tool.
To configure the detection tool, do the following:
When the specified number of objects in the zone is exceeded, the detection tool generates the Start Time of Detection Tool Trigger event. When the number of objects in the zone decreases below the specified value, the End Time of Detection Tool Trigger event is generated.
