Abstract

An event detection system includes a processor, an electronic tracking device, and one or more transmitters. Each of the one or more transmitters can be configured to be associated with a particular individual of a group of individuals. The processor can be configured to cluster data from the one or more transmitters, and the processor can be configured to analyze the clustered data to determine one or more behavior patterns among the group of individuals. In an embodiment, video data can be combined with the electronic tracking device data in the event detection system.
