Help and Advice on installing your ANPR cameras :
In order to get the best from your ANPR (LPR) Bolt-On licence you need to make sure your camera is optimised for this task. Although your new ANPR software can cope with a wide range of angles and varying image quality it's always best to position the camera to minimise the workload of the ANPR engine software.
Our key tips are:
Reduce the number of angles between the camera and the licence plate. Where possible use cameras designed to see number plates clearly, these will typically have higher quality InfraRed LED and have circuitry to cope with headlight suppression. Set the camera exposure to have a minimum shutter speed of 500th of s second but ideally 1/1000th. In low light conditions you will normally only see the number plate in an otherwise black image, the InfraRed will reflect of the number plate, so always read the front of vehicles which are more retroreflective.. The remaining key element is plate size, the number of pixels horizontal and vertical occupied by the plate.
