| Common Event Detection |
| Multi-rules application | Set and apply multiple rules. |
| Detection area | Set detection area and 10 exclusion areas. |
| 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 | Support real-time analysis on number of people entering and leaving one area in video channel;
Target pixel ≥60×60, and accuracy >93% (in the day, no obvious obstacles). |
| Tripwire | Automatically detect tripwire crossing;
Target pixel ≥60×60, recall rate ≥90%, and effective rate ≥90%. |
| Intrusion | Monitor the forbidden area and give an alarm;
Target pixel ≥60×60, recall rate ≥90%, and effective rate ≥90%. |
| Abandoned object | Monitor suspected abandoned object in key protection areas, and give an alarm (bags, luggage and boxes);
Target pixel ≥60×60. |
| Loitering detection | Monitor people staying in key protection areas and give an alarm;
Target pixel ≥60×60, recall rate ≥90%, and effective rate ≥90% (less than 5 people). |
| Fast moving | Detect fast moving and give an alarm;
Target pixel ≥60×60, recall rate ≥80%, and effective rate ≥80% (less than 5 people). |
| Fighting detection | Detect fighting and give an alarm;
Support 8-channel analysis,
The fighting target takes up 1/4 × 1/4 of the image. |
| Wrong-way detection | Monitor pedestrians who walk in the wrong way in unidirectional areas, and give an alarm;
Target pixel ≥60×60, recall rate ≥90%, and effective rate ≥90% (less than 5 people, no obvious obstacles). |
| Escalator abnormity detection | Support real-time monitoring of sudden stop and reverse operation of escalators;
Target pixel ≥60×60. |
| Report generation and export | Export alarm information in Excel, including channel name, event time, event name, event type, rule name, rule line, scene and target box. |
| Alarm search | Search alarm information by device, channel, event type and snapshot time. |
| Common Event Detection Application Scene |
| Scene | Widely applicable to airports, subways, railway stations, squares, service halls and malls. |
| Camera installation |
