Smart Event

IVS

Abandoned object; missing object

Intelligence

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

Face Detection

Face detection; track; snapshot; snapshot optimization; optimal face snapshot upload; face enhancement; face exposure; face attributes extraction including 6 attributes (gender, age, glasses, expressions, face mask, and beard) and 8 expressions (angry, sad, disgusted, scared, surprised, calm, happy, confused); face snapshot set as face or one-inch photo; snapshot strategies (real-time snapshot, quality priority and optimization snapshot); optimization time setting

Face Recognition

Dahua Face Recognition Technology extracts attributes from the captured face, compares it against the attributes in the face library, and then identifies the person. Management of 5 group face libraries,Max supports face contrast in face library with 25,000 faces

People Counting

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

Video Metadata

Motor vehicle, non-motor vehicle, face, human detection; track; snapshot; snapshot optimization;
optimal face snapshot upload.
Motor vehicle attributes: license plate, vehicle type, vehicle color, vehicle logo, seatbelt, smoking, calling,etc.
Non-motor vehicle attributes: type, color, number of people, top type and color ,helmet.
Human body attributes: top/bottom type and color, bag, hat, gender, and umbrella.
Face attributes: gender, age, expressions, glasses, face mask and beard.
