PROBLEM TO BE SOLVED: To provide the antitheft device with the image storing function of storing images obtained by a CCD camera and sensor data by the abnormality detection of the sensor data and the detection of wire disconnection of the camera so as to leave the criminal determination evidence of the theft of a safe or automatic vending machine and a breaker. SOLUTION: This antitheft device has a wire breaking sensor 10 which detects whether or not there is the signal of the CCD camera 2 mounted on the facilities, an arithmetic processing part 152 of a CPU 15, and a storing process part 151, the arithmetic processing part 152 sends a decision signal regarding whether or not the sensor data are abnormal to the storing process part 151 with the signal from a sensor part 3, and the storing process part 151 has the image storing function equipped with a means which transfers the data of a RAM 14 to a flash memory 16 when the sensor data are abnormal and inhibits the storage from being updated after the data are stored and held and a means which stores and updates the sensor data preferentially to abnormal operation when the wire L of the CCD camera 2 is broken.
