Smart Event

IVS

Abandoned object; missing object

Professional, intelligent

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, 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); face angle filter; optimization time setting

People Counting

Tripwire people counting, drawing polygonal lines for tripwire, generating and exporting report (day/week/month/year);

People counting in area, generating and exporting report (day/week/month);

Queue management, generating and exporting report (day/week/month);

4 rules can be set for tripwire, people counting in area and queue management;

Supports crowd detection;

Supports intelligence trajectory.

Abnormal Behavior Analysis

Leave post detection which triggers alarms when no one is in the detection area, personnel have left their post or there is an abnormal number of people on duty in the detection area. Supports setting up to 20 personnel on duty at the same time.

Smart Search

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