AbstractA personal data unit (PDU) is operable to collect video information via a camera (12) and audio information via a microphone (14). The PDU (10) utilizes a cellular link for transmission of the collected information to a central station (27). Position/time information is received from a GPS satellite network (22) via an antenna (24). This allows the system to be packaged such that it can be attached to an individual and carried with that individual.
