Smart Event

IVS

Abandoned object; missing object

Heat Map

Yes

Professional, intelligent

IVS (Perimeter Protection)

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

SMD 3.0

Less false alarm, longer detection distance

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

Supports 4 rules to count the number of people entering and exiting separately; generating and exporting report (day/month/year); 4 rules can be set for people counting in area and queue management, and it will trigger alarm linkage when the number of people queued or queue time exceeds the threshold.

Intelligent Search

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