The accuracy and effectiveness of Automatic Number Plate Recognition cameras have made them an essential tool for modern car park management.
The images captured by these cameras can create an accurate picture of how people are using your car park, and notify you of anyone who is breaking the rules (for example if they haven’t bought a parking ticket).
You can also choose to use ANPR alongside a barrier system. When the camera detects a known vehicle entering the site, you can programme it to automatically raise the barrier.
How Does Automatic Number Plate Recognition Work?
This technology works by capturing the number plates of any vehicles that pass by the camera. Consequently, these cameras are usually positioned at entries and exits to a site. It then automatically reads the individual letters and numbers that make up a vehicle registration, using Optical Character Recognition (OCR) software. This information is then checked against the database records.
The data that the cameras collect is made up of ‘read’ and ‘hit’ data.
- Read data: This is the data that the camera collects as the vehicle passes through the ANPR reader.
- Hit data: This is a match to a VRM already held on the database records.
Advances in ANPR Technology
In the past, ANPR was costly, unreliable, and only used for a few purposes. Errors were frequent, because the available hardware at the time could not read every licence plate reliably. It was inconvenient too, as due to the frequent errors, it couldn’t operate without human confirmation. Furthermore, poor lighting and non-standard characters caused issues with detecting and capturing vehicle registrations.
However, the latest advances in Automatic Number Plate Recognition have set new standards for accuracy. Hikvision ANPR cameras are now packed with a host of ground-breaking features, making them suitable for a wide range of projects. To illustrate this point, we’ve listed some of the more typical ANPR applications below.
Uses for Private ANPR
- Site entrances
- Car park management and access control
- Leisure, hotels, and commercial
- Petrol station drive-offs
- Industrial estates
- Shopping centres
- Golf clubs
- Clubs and pubs
- Logistics and vehicle tracking
Hikvision ANPR Cameras
Hikvision ANPR cameras are much more efficient and accurate than traditional systems. They also don’t need any frequent and annoying camera positioning adjustments, which was a problem with the systems of old.
Evolution CCTV and Electrical can install Hikvision ANPR cameras for you, which feature:
- Unsurpassed accuracy
- Full motion clips or single ANPR images
- Full graphical reporting
- Sophisticated vehicle database
- A network version for larger projects
