ABSTRACT:
An antitheft device is provided which is attached to a product such as an OA apparatus for detecting theft of the product and issuing an alarm. When vibration is detected by a vibration sensor, move distance estimating means estimates a distance of movement of the product from the start of vibration based on the time interval between vibrations detected by the vibration sensor and the number of times vibration is repeated. When the estimated distance of movement has become greater than or equal to a predetermined distance, alarming means issues an alarm by means of a speaker or the like. Schedule management means causes monitoring to be executed only in a preset day(s) of the week or in a preset time zone.
