ABSTRACT:
A system and apparatus for detecting unauthorized movement of a moveable object where the system includes a GPS receiver, cellular modulator, processor, pager modem, sensor and two-way pager. When the system is coupled to a moveable object and is armed via the pager, the sensor is monitored by the processor to determine when a possible theft of the moveable object may be occurring. In an embodiment, the sensor is a multiple axis accelerometer. In one embodiment the accelerometer is a two axes accelerometer where the sensor detects small movements of the object is two axes. When the sensor is triggered, the processor pages the two-way pager. The processor also determines the system's location via the GPS receiver. The processor generates a message including the system's location and unique system identifier. The processor transmits the message to a monitoring center via a cellular network (and the cellular modulator). In one embodiment, the message is a text message and transmitted using a GSM, GPRS, or Short Messaging Service cellular based network.
