Abstract

This invention relates to a system for monitoring the movements of people in an office or other environment. Each room to be monitored has within it a sensor responsive to signals transmitted by identifiers worn by the people whose movements are being tracked. The identifier signals give the identity of the person allocated that identifier. The sensors are themselves polled periodically by a computer to generate time-stamped records of who was within range of which sensor. When an event is to be recalled, other time-stamped audio or video records of what was said or done in each monitored room are scanned for that record which was being generated at the time of the event in question.
