Motion sensitive anti-theft device with alarm screening

(57) The move detection theft detector system for summary personal effects is characterized by the two-way communication between the theft detector unit which was attached in the carrying article or was attached to the carrying article, and the control unit which has and is mainly carried more. A theft detector transmits a caution signal to a control unit so that an alarm can be caused in a carrying article, when a user sorts out an incorrect alarm and there is a justifiable reason. A system can be carried by an operating state, without generating the watch sound frequently repeated in a control unit by the timing based on a warning deterrence algorithm. The 2nd alarm function chosen with a mode switch sounds an alarm automatically according to the arrangement of the alarm which answers movement and is adaptable. In order for an adaptable alarm to answer the frequency and continuation time of movement and to change an alarm, single-engined movement causes warning, but movement to continue causes the maximum alarm.
