Smart track
Select the
Smart Track
check box, and when alarm is triggered by the
panoramic camera, the speed dome automatically turns to the position
where alarm 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: Turns to crowd with highest density.
Detect local alarm only: Turns to local area that triggers alarm first.
Detect global alarm + one local alarm: First turns to local area, and then
the crowd with highest density when there is no alarm in local area.
Detect global alarm + multiple local alarms: First turns to local area that
triggers alarm first, and then the crowd with highest density when there
is no alarm in local area.
Before enabling this function, you need to configure Smart Track. For
details, see "5.2 Setting Smart Track."
