Patent ID: 7315321

Claim:
A system for warning about an unauthorized object attached outside a vehicle on a bottom and/or on adjoining areas of the vehicle, comprising server means for storing optical images of bottoms and/or adjoining areas of vehicles or the data corresponding to the optical images; image producing means for optically examining a bottom and/or adjoining areas of the vehicle by optically observing the bottom and/or adjoining areas of the vehicle outside of the vehicle and transmitting an optical image of a bottom and/or adjoining areas of a vehicle or the data corresponding to the optical images to the server means, which server means include a comparison unit which is configured for automatically without a user comparing the transmitted optical image of the bottom and/or adjoining areas of the vehicle or the data corresponding to the optical images with stored optical images of a bottom and/or adjoining areas of a corresponding vehicle or the data corresponding to the optical images so as to automatically without a user distinguish a bottom of a vehicle and/or an adjoining area of the vehicle on which an unauthorized object is attached, from a bottom of a vehicle and/or an adjoining area of the vehicle on which an unauthorized object is not attached; and which server means is configured so that, based on results of the automatic without a user comparison, automatically without a user producing a signal indicative of whether on the bottom and/or on adjoining areas of the examined vehicle outside of the vehicle an unauthorized object is located or an unauthorized object is not located so that not only the storing of the optical images of the bottoms and/or adjoining areas and the optically observing of the bottoms and/or adjoining areas and transmitting of the optical images are performed, but also both the comparison and the indication signal are produced by said server means without a user.
