Analytics+ Functions²
Perimeter Protection
• Detects human or vehicle violations using the following
methods:
Tripwire: a target crosses a defined line.
Intrusion: a target enters or exits a defined perimeter.
• Filters actions that may produce a false alarm due to
animals, leaves, and bright lights.
Face Recognition
• Detects and captures a snapshot of a human face within
a scene.
