ANPR
An ANPR system (automatic number plate recognition) that reads vehicle plates in real time for parking, tolling and traffic enforcement.

The Alfabeta ANPR system (automatic number plate recognition) detects vehicles, locates their number plates and reads the characters from live camera feeds, day or night. At its core is optical character recognition (OCR) trained on real traffic imagery, so this license plate recognition engine copes with motion blur, glare, dirt and varied plate formats, delivering reliable reads across gates, lanes and open roads. It can recognise plates in different colours and from many types of vehicle, from motorcycles to heavy trucks.
Each read is time-stamped and can be matched instantly against whitelists, blacklists or payment records to automate entry, billing and enforcement. The system can capture multiple plates in the same scene, which suits busy multi-lane environments, and it already handles more than one million active LPR reads per month across live deployments. Whether you run a single boom gate or a highway gantry, the same engine scales to your lane count and traffic volume.
Deployment is flexible: processing can run on edge LPR cameras or on centralised servers, letting you match latency, bandwidth and cost to each site. The ANPR system integrates with barriers, payment platforms and traffic management systems through documented APIs and event streams, so a confirmed read can raise a boom, open a turnstile or post a parking charge without manual intervention. This makes ANPR parking barrier-free and cuts the staffing and queues associated with ticketed entry.
Because the technology is offered as an API, license plate recognition slots into existing operations with minimal custom development, and it complements Alfabeta products such as the Alfa Gate Management System. Pricing follows an adjustable tiered model based on monthly API call volume and usage frequency, so cost tracks the number of vehicles you actually process. The result is faster, more accurate vehicle identification for parking operators, toll roads, secure facilities and logistics yards.
Real-Time Plate Reading
Detects and reads plates from moving vehicles in live video using OCR, enabling barrier-free entry and exit. It can capture multiple plates in a single busy scene.
Day And Night Accuracy
Handles glare, headlights, motion blur, dirt and low light for dependable reads around the clock. It also recognises plates in different colours across many vehicle types.
List Matching
Instantly checks each plate against whitelists, blacklists and payment records to trigger actions. Time-stamped reads give you a complete, searchable vehicle log.
Gate And Barrier Control
Opens booms and turnstiles automatically for authorised vehicles, cutting queues and staffing. A confirmed read raises the barrier without any manual ticketing.
Edge Or Server Deployment
Processes on the LPR camera or centrally to match your lane count, latency and bandwidth needs. The same engine scales from a single gate to a multi-lane highway gantry.
System Integration
Feeds parking, tolling and traffic platforms through clean, well-documented APIs and event streams. It complements the Alfa Gate Management System for a ready-made stack.
Frequently asked questions
How accurate is the ANPR system, and does it work at night?
The engine uses OCR trained on real traffic imagery to handle motion blur, glare, headlights, dirt and low light, so it reads plates reliably day and night. Real-world accuracy depends on camera angle, resolution and vehicle speed, which we tune during installation. It also recognises plates in different colours and from a wide range of vehicle types.
Can it read multiple plates and different plate formats at once?
Yes. The system can detect and read several plates in the same scene, which suits busy multi-lane gates and open roads, and it supports varied plate formats and colours across motorcycles, cars and heavy vehicles. It currently processes over one million LPR reads per month across deployments.
How does it connect to gates and payment systems?
Reads are exposed through documented APIs and event streams, so a confirmed plate can raise a boom, open a turnstile or post a parking or toll charge automatically. It integrates with barrier controllers, payment platforms and traffic management systems, and complements the Alfa Gate Management System.
Can we run it on the camera or does it need a server?
Both options are supported. Processing can run on edge LPR cameras for low latency and reduced bandwidth, or on centralised servers when you want to consolidate many lanes. The same engine scales from a single boom gate to a multi-lane highway gantry.
How is ANPR priced?
Pricing follows an adjustable tiered model based on monthly API call volume and usage frequency, so cost tracks the number of vehicles you actually process rather than a fixed licence. Our team helps you choose a tier that fits your site's traffic and scales it as volume grows.
