License Plate Recognition Cameras

License plate cameras are intended to take shots of moving vehicles to help capture license plates on moving vehicles. With IR technology, these cameras can highlight LP's for easy reading.

License plate cameras are cameras which can extract numbers and letters from a license plate using infrared illuminators or ambient lighting. Most cameras are able to catch license plates during the day. Some security cameras even come equipped with long distance lenses for capturing license plates which are far away. The difference between a traditional security camera and a license plate camera can be seen at night. A typical security camera is unable to process the reflecting light bouncing off a license plate. Without infrared, a regular security camera will capture a poorly lit image with too much static. With infrared, it will be blinded by the infrared light being reflected off the license plate. License plates in most states are made with a reflective coating which allows law enforcement to easily identify a vehicle. A true license plate camera uses a high contrast image sensor and long distance infrared illuminators to extract sharp license video. Because it can capture images before or after a vehicle passes its field of view, LPR cameras are able to see through brake lights and headlights. Some license plate cameras are made for short distances and slow movement. These types of cameras might work for a residential gate or a parking garage where a barrier is present. Other locations like toll roads require a more demanding camera. High speed license plate cameras use slow shutter speed image sensors like the ones used in motorsports to capture images of cars moving faster than 45mph. With the advancement of the LPR camera, there has been an increase in demand for software which can not only capture a license plate but also store it in a database for future reference. More advanced license plate capture software can integrate with access control to combine vehicle information with an ID badge.

In the ever changing world of technology and crime, it’s no coincidence license plate recognition cameras have become increasingly popular.

The technology, which was invented by the UK’s Police Scientific Development Branch in 1976, has come a long way through the years. What used to only be available to law enforcement and government is now accessible to the general public.

Police departments all over the world have been utilizing these cameras to identify suspicious vehicles, catch people with active warrants, and solve crimes. A study in 2012 showed 71 percent of police departments in the U.S. use some form of this technology and that number was only expected to rise. Toll roads and toll ways around the world use the same high tech imagery to process fees for drivers using these roadways.

Lenders and repossession agent have put these same systems into place to be able to dredge up delinquent auto loans recipients.

Whether it be theft or vandalism, criminal activity is on the incline and suburban areas are often the target. Because of this up swinging trend the need to protect our families and homesteads from outsiders has become even more prevalent. Having the ability to monitor suspicious vehicles and or behavior in residential areas is increasingly important to both home owners and HOA’s alike.

While most cameras have the ability to capture license plates during the day LPR is the only class of camera that is able to capture these images clearly at night. And the reason is quite simple. A normal camera does not have the capability to filter out visible light from tail lights/head lights/ brake lights. Because of the reflective lighting a non LPR will only be able to pick up a hazy flash of light while an LPR camera will make that image clear.

Regular camera (left) vs LPR camera (right) There a 4 primary guidelines for successful installation and operation of your LPR camera.

1- Camera Angle- Having the camera angled correctly is imperative . unfortunately , There is no exact science to this, and the best approach seems to be one involving trial and error. According to one expert the best method to determine if your camera is catching the right angle is to set it up, test run it and make adjustments as needed.

2- Shutter speed- While selecting the appropriate range camera is essential another element to be considered is shutter speed. IF the shutter speed is set to low the image won’t be captured too high will result in a darkened image.

3- Area Lighting- Another factor to keep in mind is how well lit the area is. If there is ample lighting, during both day and night, there may be no need for additional lighting. However, if a lighting source such as a street light is not available, IR illuminators would need to be purchased to provide sufficient luminosity. This device can be mounted just above or below the camera for optimal results.

4- LPR Software- In order to maximize the benefits of your LPR camera in needs to be integrated with dedicated LPR software. The main purpose of this software is to store the images into a database. This stored information will come in handy in almost any scenario involving your LRP camera.

It’s important to keep in mind what functions you will need your LPR camera to be capable of. A toll way where vehicles are going in excess speed of 60+ mph would require a long range high speed LPR while a short range low speed LPR would be best suited for a residential area. The model of LPR camera you decide to choose is heavily based on what you are trying to accomplish. For more information on LPR cameras or to chat with a live rep please click link below.
