Abstract
A system for automatically capturing an image of a moving vehicle and recording data parameters, such as date, time, speed operator, location, etc. on the image. A capture window that comprises a predetermined range of distances of the system from the moving vehicle can be set by the operator so that the image of the moving vehicle is automatically captured when it enters the capture window. The capture window distance can be entered manually through a keyboard or automatically using the laser speed gun. Automatic focusing is provided using distance information from the laser speed gun. A database is included to allow the user to search for specified parameters. Data records can be flagged for issuance of citations. A separate office unit is disclosed for retrieving and sorting data records so that field units are not occupied with such tasks. The office unit can be separately connected to licensing databases to retrieve information for issuance of citations.
