License Plate Recognition (LPR) cameras are useful tools for reading and recording vehicle plates. They help with parking control, traffic monitoring, toll collection, and even safety.
But to get the best results, these license plate recognition cameras need to be placed in the right spots. Good placement makes the system more accurate and helps it work well in all kinds of weather and lighting.
Choose the Right Height and Angle:
One of the first things to think about is how high the camera is placed. LPR cameras work best when they are not too high or too low. The ideal height is usually between 3 and 4 feet above the ground for ground-level setups, or slightly higher for pole-mounted cameras, depending on the angle. The camera should face the license plate directly or at a slight angle. If the angle is too steep, the plate may not be readable.
Position Near Entry and Exit Points:
LPR cameras are most useful when placed where vehicles naturally slow down or stop. Entry and exit gates, parking lot entrances, and toll booths are perfect spots. When cars are moving slowly, the camera has more time to capture a clear image. Placing cameras in these areas helps catch plates before cars speed up or turn.
Avoid Glare and Shadows:
Lighting is very important for LPR accuracy. Bright lights, direct sunlight, or headlight glare can make it hard to read the plate. Try placing the camera in a shaded area or use special filters or covers to block unwanted light. Some LPR systems also work better with infrared lighting, which allows them to capture clear images even at night.
Keep the Camera Focused on One Lane:
It’s best to aim each camera at one lane of traffic. Trying to cover too many lanes with one camera can lower the chances of getting a clear plate image. When cameras are focused on a single lane, they can zoom in and give a sharper, more readable picture. This setup also makes it easier to track which car was in which lane.
Regular Checks and Cleaning Help:
Even with perfect placement, the camera needs to be checked often. Clean the lens, remove any dirt or spider webs, and make sure the view isn’t blocked by trees or signs. A little care goes a long way in keeping the system working well.
