5.5.5.1 Tripwire
Alarms are triggered when the target crosses the warning line in the defined direction. It
requires certain stay time and moving space for the target to be confirmed, so you need to
leave some space at both sides of the warning line during configuration and do not draw it
near obstacles.
Applicable scenes: Scenes with sparse targets and no occlusion between targets, such as
perimeter protection of unattended areas.
