Abstract: A student tracking system deploys distributed sensors throughout a school building. The distributed sensors receive identification information broadcast by user devices carried by occupants of the school such as students, teachers and school administrators. The student tracking system tracks the location of the occupants within the building based on which sensors most recently detected the user devices. The system sends the location information for the occupants to tracking devices operated by tracking users such as school administrators, emergency responders and/or parents. The tracking devices also present to the parents image data captured by surveillance cameras depicting the students. Additionally, the distributed sensors detect the presence of unauthorized individuals within the school building by determining whether an individual detected via a proximity or motion detector corresponds to identification information for a registered user device received by the sensors.
