THEFT DETECTION SYSTEM AND METHOD

摘要

A theft detection system includes an accelerometer (20) attachable to an object (12), the accelerometer providing an acceleration signal in response to movement of the object; an alarm mechanism (24) for providing a signal in response to movement of the object; and for preventing false alarms, a filter (36) 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.
