Optimized Access Control

The Carmen® ANPR/ALPR API or Cloud SaaS is designed for system integrators to be implemented into automated access control systems. With Carmen®, you can create VIP- or blocklists or assign particular access levels to different visitor segments. Thanks to access control automation, waiting times at barriers are reduced, the human error factor is eliminated, and the whole process becomes touchless. When integrated, the Carmen® ANPR/ALPR software can be the cornerstone of such automated access control systems.

Have Full Control Over Your Access Management

Airports, hotels, business centers, industrial zones, highly-guarded areas, gated communities, or ports: Carmen® instantly and automatically provides the required license plate data to grant or deny access to vehicles based on your VIP or unauthorized list. With features like the optional Make and Model Recognition engine or the ADR and IMO add-ons, vehicle- or owner-based admittance becomes possible.

Implementing Carmen® into existing access control systems is not an issue thanks to our solution’s versatility. The software comes in various forms like on-premise SDK engines, the plug’n’play Carmen® GO or the fully cloud-based ANPR Cloud.
