How ANPR Works – Technology & Process
Our ANPR Parking System operates through a precise and intelligent multi-stage process:
1. Vehicle Detection
As a vehicle approaches the entry or exit gate, loop detectors or radar sensors detect its presence and trigger the ANPR camera.
2. High-Resolution Image Capture
The ANPR Camera for Parking captures a clear image of the vehicle’s license plate under varying lighting and weather conditions, including low-light environments.
3. Plate Recognition & OCR Processing
Using advanced AI-powered algorithms, the system extracts the alphanumeric characters from the number plate using Optical Character Recognition (OCR).
4. Database Verification
The extracted number is automatically cross-checked against:
- Whitelist database (authorized vehicles)
- Blacklist database (restricted vehicles)
- Visitor or temporary access list
- Parking subscription records
5. Automated Access Decision
Based on the verification result:
- The boom barrier opens automatically for authorized vehicles.
- Access is denied for unauthorized or blacklisted vehicles.
- Alerts are generated for security personnel when required.
6. Data Logging & Monitoring
Every entry and exit is recorded with:
- Time stamp
- Vehicle number
- Image capture
- Entry/exit location
This creates a complete audit trail for security and analytics purposes.
