When the GPS receiver 42 is located at the location reached by the GPS receiver 42, the GPS receiver 46 included in the anti-theft unit 40 of the camera 10 uses the GPS radio wave 42 transmitted from the GPS satellite 44 and the differential signal
64 and receive the position information signal 47
Are continuously transmitted to the position determination device 48 (FIG. 1). GP
S receiver 46 is inferior to DGPS in terms of accuracy,
Positioning can also be performed using only 42. When receiving the position information signal 47, the position determination device 48 determines whether or not the camera 10 exists in the area 80. That is, the area data of the built-in ROM 58 is collated with the position information signal 47 to determine whether the camera 10 is located inside or outside the area 80. When it is determined that the vehicle is out of the area, the theft is determined to have been performed, a theft signal 50 is output, and an alarm is issued by the alarm device 52.

S When the radio wave 42 does not reach, for example, when brought into another building area 88, or even within the area 80, the user of the camera 10 puts the camera 10 in a container that shields the radio wave,
If the GPS receiver 46 cannot receive the GPS signal 42,
The S receiving device 46 does not perform positioning and does not output the position information signal 47. Also in this case, the position judging device 48 outputs the theft signal 50 and the alarm device 52 generates an alarm.

When the GPS receiver 46 is controlled by the CPU 54 and performs positioning, the GPS receiver 46 continuously or periodically sends a position information signal 47 to the position determining device 48, and the position determining device 48 is similarly controlled by the CPU 54. And the location information signal
While receiving 47 (step 100), it is determined whether the camera 10 is inside or outside the area 80 (step 102).
If the state in which the position information signal 47 cannot be obtained continues for a certain period or more, the theft signal 50 is output (step 104).
