System for controlling the entry of vehicles into a secure area, which utilizes license plate numbers for identification. The system is installed at the entrance gates and consists of a camera, a computer, and control software for opening the barrier. The barrier opens automatically upon detecting a vehicle entering with a license plate number that is on the list of authorized vehicles. The definition of authorizations allows not only the entry of the license plate number but also other vehicle characteristics (such as manufacturer or country of origin). It is also possible to define complex rules for controlling authorizations, depending on factors such as the time of day, day of the week, user groups, and more.
