ANPR – Automated Number Plate Recognition
ANPR is a technology that uses optical character recognition on images to read vehicle registration plates to create vehicle location data
ANPR was invented in 1976 at the Police Scientific Development Branch. Since then there has been a huge surge in the use of ANPR cameras with motorists being identified in some cases hundreds of times per day.
Privacy issues have caused concerns about ANPR, such as government tracking citizens’ movements, misidentification, high error rates, and increased government spending. Critics have described it as a form of mass surveillance.
The Above ANPR Camera is a Popular Choice in the UK. The Following Parts Make up the Design:
- Outer 4 lenses: High power pulsed 850nm LEDs for total scene illumination.
- Top middle motorised lens: Daylight camera for general scene capture after successful ‘read’.
- Bottom middle motorised lens: Infrared filtered ANPR camera designed only to detect infrared light reflected from vehicle plate.
- Main body: Houses on-board Linux based operating system with OCR engine and IP connectivity.
- Adjustable sun shield: Blocks lens glare due to unfavorable sunlight angles.
- Mounting bracket: Allows adjustment in multiple axis for optimum reading angle.
