Number Plate Recognition (ANPR) in Aberdeen
Automatic number plate recognition (ANPR) is a mass surveillance method that uses optical character recognition on images to read vehicle registration plates. ANPR can be used to store the images captured by the cameras as well as the text from the license plate, with some configurable to store a photograph of the driver. Systems commonly use infrared lighting to allow the camera to take the picture at any time of the day.
Many businesses now use ANPR cameras as part of their access control system. It is commonly used for car parks for parking management, logistics, recognized customer and VIP recognition. ANPR can be used to store the images captured by the cameras as well as the text from the license plate, with some configurable to store a photograph of the driver.

Realm Fire & Security has expertise in designing and installing security cameras and CCTV systems in Aberdeen. From simple home security cameras for small shops and businesses to large complex projects such as oil companies with numerous buildings, we have a solution for every use.
These cameras are suitable for a wide range of applications but are particularly suited to automatic entry systems and include Automatic Number Plate Recognition (ANPR) Technology. It is essential with all ANPR systems to install the camera in the right location and this can become challenging at entrances with gates or barriers. In order to grant access to the correct vehicle, the ANPR camera must view the first vehicle in the queue. This can be almost impossible with a pole-mounted ANPR camera, particularly if the barrier is fitted with skirts or for gated entrances. The bollard camera is the ideal solution as it ensures that the camera can be installed in the perfect location for maximum recognition accuracy.
The bollard camera can be supplied in a range of custom colours to suit the intended location and has been designed to resist vandalism. The cabinet is constructed from 2mm steel and is complemented by a 6mm thick Lexan window. The full height rear access door simplifies both installation and maintenance and is fitted with a key lock as standard. The low height of this ANPR bollard camera ensures that the license plate images are extremely sharp and free from skew, so allowing the ANPR processor to achieve maximum recognition accuracy. To minimise image degradation from the sun, these new models now feature an extendable sun hood which provides additional shade for both the ANPR and optional overview camera.
Dual Camera Vision
These bollard ANPR cameras employ special optical filtering to ensure that highly reflective vehicle registration plates are correctly exposed under all lighting conditions. Whilst this ensures our processors achieve the highest possible recognition accuracy, it does also mean that images from an ANPR camera are rather dark and lacking any colour information. If you need additional colour images of each vehicle in order to assist in determining make, model and colour, you will need to select the dual version of the bollard camera. This includes both an ANPR camera plus an additional, high-resolution overview camera. Our overview cameras feature a Sony ExView sensor and offer very sharp, full-colour images with 560 tv line resolution. Like the ANPR camera, the overview camera has a simple adjustment of both zoom and focus. Whilst the ANPR camera will not be affected by headlight glare, remember that the colour overview images at night will not be ideal due to the very low camera position. If you require high-quality overview images at night when using a bollard camera, please consider using our stand-alone day/night overview camera and installing this at a height sufficient to avoid headlight glare.
