Video Metadata
Motor vehicle, non-motor vehicle, face, and human body detection; optimization; capturing pictures; uploading high-quality snapshots; extracting 12 attributes from vehicles
IVS (Perimeter Protection)
Tripwire; intrusion; crossing fence detection; loitering detection; abandoned/missing object; fast moving; parking detection; people gathering; vehicle/human alarm classification; linkage tracking
Face Detection
Supports face detection, face bounding box, optimization, capturing snapshots, enhancing face images, and uploading high-quality face snapshots, and extracts 6 attributes and 8 expressions from face images. Face cutout is also offered, where you can cutout one face at a time and customize the size to be a one-inch photo. The supported methods for capturing snapshots are real-time capturing, optimization and quality first
