License Plate Camera

Understanding License Plate Cameras

Monitoring vehicles on a property is a very important part of a video surveillance system. However, it is one of the most challenging things to do. Accurately capturing license plate images requires the use of a specific type of CCTV camera. Not only that, the camera has to be mounted and setup in a specific way. These cameras have been specifically designed to reduce glare from headlights and taillights. They also have a built in adjustable focul length lens and high powered IR lights.

Why is capturing a license plate so difficult?

There are several issues that make capturing license plates so difficult. Each one needs to be addressed when setting up a license plate camera.

Vehicle Speed
Most vehicles are not sitting still. They are moving. Sometimes at a high rate of speed. This causes the image to blur because of the movement of the vehicle and its license plate. The easiest way to combat this is by picking a capture area where a vehicle will naturally be traveling at a slower rate of speed. Also, having a camera that is designed specifically for capturing license plates will help because they have shutter controls to help compensate for the movement. 

Vehicle Position in Relation To Camera
The angle that you are attempting to capture the plate is very important. If you have a large degree angle then the lettering on the plate is less visible to the camera. Making it more difficult to capture.


Dedicate A Camera for License Plate Capture
We have all watched a CSI episode on TV where they are able to digitally enhance a blurry overview image and get a license plate. This makes for great TV but it's not how it works in the real world. If you plan on accurately capturing license plates you should dedicate a camera for that specific purpose. This allows you to pick a location, choose the right camera type and set it up in a way that will allow you to have the best chance of capturing quality plate images.

Another major issue that comes up when trying to capture plates is the glare from headlights and taillights. This becomes especially difficult at night when the overall ambient light is very low. License plate cameras are designed to block out the glare from the lights of the vehicle allowing you to see the plate.
