You can use the VI detection of crowd module as a part of video surveillance systems at sites characterized by mass crowds of people (subways, train stations, airports, other transportation infrastructure facilities, museums, shopping and entertainment centers, sports facilities, and so on) in order to automatically detect the situations in which the number of people exceeding the specified threshold gathers in the camera FOV.

The VI detection of crowd module is used for solving the following tasks:

1. Detection of crowding and congestion of large numbers of people moving through building entrances, through narrow passages, on approaches to escalators during mass events.

2. The detector is in the normal (non-alarming) state when the dense crowd is moving through the controlled area at a low speed. If the crowd stops, that is, at the moment of congestion formation, an alarm is generated (the Crowd event).
