Description
Global
Select the
Global
checkbox and set the crowd density
threshold. The system detects crowd distribution in the global
area. When the crowd density exceeds the configured
threshold, the system performs alarm linkages.
Crowd Density
Smart track
When an event is triggered by the panoramic camera, the PTZ
camera automatically turns to the position where event is
triggered. The tracking time is "idle time + five seconds." For
the details of idle time configuration, see "5.2.2 Enabling
Alarm Track"
Linkage rules:
●
Detect global alarm only: Priority is to the crowd with
highest density.
●
Detect local alarm only: Priority is to the local area that
triggers event first.
●
Detect global alarm + one local alarm: Priority is to the
local area, and then the crowd with highest density
when there is no alarm in local area.
●
Detect global alarm + multiple local alarms: Priority is
the local area that triggers event first, and then the
crowd with highest density when there is no event in
local area.
Before enabling this function, you need to configure Smart
Track. For details, see "5.2 Setting Smart Track".
