Security systems and methods (10, 10', 10") configured for use with an item of merchandise (20, 20', 20") for retail display include a housing (21, 51', 56"), at least one sensor (26, 26', 26") carried by the housing, and at least one output device (27, 27', 27") carried by the housing. The security system further includes a controller (35, 35', 35") carried by the housing and operably coupled to the sensor and to the output device. The controller is operable to determine a distance traveled by the item of merchandise from a retail display "home" position (37, 37', 37") based upon a sensor input from the sensor, and to activate the output device based upon the distance traveled by the item of merchandise exceeding a threshold distance. The controller may utilize the at least one sensor in conjunction with an inertial navigation system (INS) and motion processing algorithms or techniques to determine the distance traveled by the item of merchandise from the retail display "home" position. The components (sensor, controller and output device) of the security system may belong to an electronic item of merchandise being displayed and configured in an anti- theft mode or externally applied to the item. A potential purchaser is free to examine the item but is prevented from stealing it. |
