Crowd Detection
Crowd detection calculates the number of people in a specic area. When the number exceeds
a preset number, an event is triggered.
The applicable scenarios of this feature can be:
* Detects the congestion when the number of people in a region exceeds a preset number, e.g.,
10 in a waiting line. For example, at an airport, when too many passengers are waiting in line,
new checkpoints can be opened, and they can be directed to other checkpoints.
* To monitor a special area where at most one person is allowed inside. For example, one
person is normally allowed in the area in front of an ATM machine or a strictly guarded
entrance. Tailgating can occur if one uses his/her access card to open a gate while the other
sneaks in following behind.
