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

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.

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.
