Gate Access Control System is a production-ready solution for managing vehicle access at a parking lot. The system automates gate operations by verifying vehicles against an authorization database using license plate recognition or phone-based identification.
The architecture consists of three independent services: a backend API responsible for business logic and access rules, a Vue 3 single-page application for administrators and security staff, and a dedicated Python computer vision service that processes live RTSP camera streams and performs real-time vehicle and license plate recognition.
Once a vehicle is successfully verified, the backend communicates with ESP microcontrollers to physically control barrier gates. All access attempts are logged, providing a complete audit trail.
