Nowadays, parking lots are becoming an organic par of our everyday life. Carmen Parking offers flexible, low maintenance, yet effective and intelligent technology for car park operation. It reduces costs as well as increasing efficiency and security. Carmen Parking is a core technology rather than a complete application, as it was specially designed and developed to be easily integrated into complex parking and access control applications. As a flexible system it can be tailored to meet special customer requirements. The Carmen Parking ANPR package contains the following elements: Automatic number plate recognition engine FXVD4mc_s grabber card Functions library (ANSI C/C++, MSVC/C++, MSVB and Delphi, ActiveX, OCX) Demo and test applications Tutorial and sample programs both in executable and source code Optionally provided device: High Resolution Ultra Low Lux B/W Camera equipped with a special and synchronised IR flash. To achieve the best image and avoid any compatibility difficulties, Carmen Parking is delivered with a proprietary FXVD4mc_s video capture car. The system can be used on any existing PC system running in Windows Nt 4.0 or Windows 2000, Windows XP, Windows 2003.

Applications of CARMEN® Parking
CARMEN® Parking is specially designed for parking systems and access control systems. In LPR parking systems and LPR access control systems vehicles stop at the point of automatic vehicle identification (or slow significantly down). Also, most of the parking systems and access control systems are using standard CCTV video systems, and compatible hardware components.

Consequently the main applications of CARMEN® Parking are the following: car park management, car parking automation, occupation management, automation of access control, security access control, flotilla management (car pool management), automation of vehicle entry to and exit from car parks, inventory management, state border control, etc...
Systems using CARMEN® Parking: security vehicle plate readers, LPR parking systems, access control number plate readers, location manager vehicle license plate readers and automatic vehicle registration systems.
