Common Event Detection

Multi-rules application

Set and apply multiple rules.

Real-time display

Display rule detection areas and target detection boxes in real-time video.
Rule and target detection boxes can flicker during real-time alarm.

Crowd density detection

Support to set max 8 monitoring regions in one video channel; give an alarm when number of people in the region exceeds the threshold for certain period; give an alarm when region density exceeds the threshold for certain period; support real-time statistics of total number of people in the video of output channel; support real-time statistics and output of number of people in each monitoring area.
Crowd density:
Low density scene: People counting accuracy ≥80% (not required if there are less than 10 people);
High density scene: People counting accuracy ≥75% (20–50 people), people counting accuracy ≥80% (50+ people) (not required if there are less than 10 people).

Customer flow statistics
