Abstract
A system has a monitor attached to and monitoring sound and vision around the user and using cellular telephone communications to convey monitored information. The monitor calls a primary server which alerts a secondary server of call receipt. The secondary server calls the monitor which drops the call to the primary server after a predetermined time, and remains in contact with the secondary server only if the monitor has successfully received the call from the secondary server, thereby preventing introduction of a false monitor. The monitor has options alterable only when on a battery charging cradle. The monitor has amber and red alert modes involving further servers, providing means to monitor and record the sounds and vision. The monitor has satellite position reporting. The system employs cell phone inter base station signal strength interpolation to find the monitor'"'"'s position. A vibration motor silently alerts the user to calls.
