Rule Description Applicable Scene
Crowd gathering
When the crowd gathers or the crowd

alarm linkages.
Scenes with medium or long

station entrance and exit. It is
not suitable for short-distance

When the target loiters over the

area within the time interval of alarm,
then alarm will be triggered again.
