A vibration detector (15) mounted in each vehicle (1) detects the vibration of the vehicle. A time specification unit (20b) specifies the time at which vibration is detected. An abnormality determination unit (20a) determines whether vibration is caused due to theft action or environmental conditions based on the output of the detector (15) of each vehicle and the specification unit (20b). Independent claims are included for the following: (1) center monitoring apparatus; and (2) vehicle mounted monitoring apparatus.
