A monitoring and tracking system (300) has transmitting tags (318, 320) attachable to monitored individuals (314, 316), local monitoring devices (306, 308) and a central monitoring server (302). The transmitting tags, each having a unique code, periodically transmit data carrying signals and the signals are received by any of the local monitoring devices when a tag is within reception range of a local monitoring device for allowing tracking the monitored individuals. |
