Analytics+ Functions²
Face Recognition
• Supports five group libraries that store up to 10,000 faces on the camera.
• Captures 16 face images per second, compares to stored images, and produces match statistics.
• Extracts six attributes and eight expressions from a face capture.
• Offers face enhancement, face exposure, and a face angle filter for clear facial images
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.
