摘要

A monitor system capable of monitoring a plurality of vehicles 1 includes a vibration detection unit 15 for detecting vibration of each vehicle 1, a detection time identification unit 20b for identifying the time when the vibration is detected by the vibration detection unit of each vehicle 1, and an abnormality judgment unit 20a used when vibration is detected by the vibration detection unit 15 of any vehicle 1 for judging whether the vibration is attributed to robbery backup action performed to the vehicle 1 or the environment where the vehicle is placed. The abnormality judgment unit 20a performs judgment according to the detection result of the vibration detection unit 15 of each vehicle 1 and specification results by the detection time identification unit 20b. This reduces the possibility of erroneous determination that the vibration not attributed to robbery backup action is a vibration attributed to robbery backup action.
