The vehicles (12) are photographed frontally when they exceed the predetermined speed. Two speed measurements are effected: A first measuring value is obtained in a relatively short part of the available measuring section (22) on the entrance side and serves to release a camera (18). A second measuring value evaluates all speed measuring values occuring in the measuring section (22), in which the vehicle (12) is detected by the radar beam (20). This second measuring value is recorded.Field of SearchSpeed and overspeed | |
