Tripwire
Triggers when an object crosses a virtual tripwire line. Used where a rule exists but a fence does not.
What triggers it
A line you draw on the camera view. A tracked object crosses it and the alert fires; someone who walks up, stops and turns back does not. The line sits on the scene rather than the floor, so it can follow a platform edge or an opening with no physical marking.
What you set up
- the line, in one or more segments
- which classes count
- confidence floor
- schedule
What the operator gets
A clip of the crossing with the line and the tracked object drawn on the frame.
Where it’s used
Every site defines this differently.
What counts as an event in a hospital lobby isn't what counts on a station platform or a factory floor. Describe your scene and we'll tune the detection to it.
