Smart event

IVS (Perimeter Protection)

Intrusion, tripwire, fast moving (the three functions support the classification and accurate detection of vehicle and human); loitering detection, people gathering, and parking detection

Smart Object Detection

Smart abandoned object; smart missing object

SMD

SMD 3.0

AcuPick

Uses deep learning algorithms and works with back-end devices to accurately match targets, such as people and motor vehicles, and search through live and recorded videos to quickly locate targets.

Face Detection

Face detection; snapshot; snapshot optimization; optimal face snapshot upload; face enhancement; face exposure; face attributes extraction including 6 attributes and 8 expressions; face snapshot set as face or one-inch photo; snapshot strategies (real-time snapshot, quality priority and optimization snapshot); face angle filter; optimization time setting.

People Counting

Tripwire people counting and people counting in area; generating and exporting report (day/month/year); 4 rules can be set for tripwire, people counting in area and queue management.

Heat Map

Yes

Video Metadata

Motor vehicle, non-motor vehicle, face, and human body detection; snapshot; snapshot optimization; optimal face snapshot upload.

Extraction of motor vehicle and non-motor vehicle attributes: extracts 6 attributes for motor vehicle and 6 attributes for non-motor vehicle.

Extraction of face and human body attributes: extracts 6 attributes for face and 8 attributes for human body.

Smart Search

Work together with Smart NVR to perform refine intelligent search, event extraction and merging to event videos
