License plate recognition works when your camera captures video of a vehicle's license plate and then either stores it to review later or runs the image through video analytics software (automatic number plate recognition software - ANPR) to compare it to a database of stored license plate numbers.
You can even set your system up to send you alerts - should a match be found - straight to your email or mobile.
For an LPR CCTV camera to work well, there are a few things to take into consideration:
- Angle of the camera
- Distance from the camera to car - you want to minimise the distance where possible for clarity of picture
- Lighting - there must be enough light for number plate recognition, which may mean installation of lighting, essential if you’re needing your LPR CCTV to work at night.
- Speed of oncoming traffic - the LPR camera needs enough time to focus to capture a plate, so speed usually needs to be no more than 55km per hour, depending on the angle, distance and lighting.
The quality of the LPNR video created may also be important - if you ever need to use the video for legal purposes, you’ll need to meet the requirements of NZ law. We can advise you on all elements of getting your LPNR CCTV NZ prepped.
