Abstract
A theft detection system includes an accelerometer attachable to an object, the accelerometer providing an acceleration signal in response to movement of the object; an alarm mechanism for providing a signal in response to movement of the object; and for preventing false alarms, a filter programmed to determine the frequency of the acceleration signal and to provide an output to activate the alarm mechanism only when the frequency of the acceleration signal meets a predetermined criteria.
