Claim:
A theft detection and deterrence system comprising: an accelerometer attachable to an object, wherein the accelerometer measures the acceleration of the object and provides an acceleration signal in response to motion of the object; a processor for processing the acceleration signal to determine if the motion of the object is a hostile motion and wherein the processor provides a corresponding output; a hostility state machine responsive to the output of the processor comprising: a non-hostility state and a hostility state, the hostility state comprising an initial hostility state level and at least a subsequent hostility state level, wherein the non-hostility state represents a not-stolen status and the hostility state represents a stolen status and wherein the hostility state machine determines a current hostility state level; means for decreasing the current hostility state level when at the at least a subsequent hostility state level to the initial hostility state level; and an alarm subsystem responsive to the control signal providing an alarm signal in response to hostile motion.
