License plate recognition is a surveillance system used primarily by law enforcement to capture the license plate information of moving cars. It does this through optical character recognition of plates using cameras that generally are designed especially for this purpose, though existing close circuit cameras are sometimes used. A common situation involving license plate cameras is at an intersection where they are used to make sure red lights are adhered to. Violators are sent a ticket through the mail based on a photo taken by the system. Infrared lights are commonly used in conjunction with the camera for surveillance at night and a flash is sometimes incorporated, partly for clarity and partly as a visible cue of the offense.
There are actually two versions of the license plate camera: those that connect to a database and those that do not. While the former are used by law enforcement, the latter is ideal for those who simply want to monitor traffic within a designated area. These license plate cameras, which are cheaper in cost, are hooked up to a DVR and the surveillance footage is thereby recorded for review. Herein lies the difference between the two types. The surveillance footage must be reviewed in the second version, as there is no database to reference. Despite this, the second type of camera has its usefulness. It is often utilized by homeowners and gated communities to keep track of who enters and exits their neighborhood. It is an effective deterrent of potential crime in this way. It becomes not only effective but an affordable deterrent with the difference in cost.
One of the biggest challenges facing optical recognition is the identification of characters on the license plate because each state has an average of twelve different license plate designs and they all must be recognized by the system. The color of the plate and raised or flat letters are simply two of many variables that can affect proper character recognition. A system must also keep up with changes or additions to state’s license plates. Given this, license plate recognition systems must be very versatile. These systems are not without controversy. Privacy issues have arisen due to usage of information attained based on a vehicles license plate number and misidentification of drivers are a common concern. Despite this, these systems seem poised to stay and increase in usage.
All over the world, the last decade has witnessed a huge number of car accidents and resulted in wasting a big number of human souls among all ages, but children where the main victims in such acts. Consequently, and as a method for preventing cars, buses, motorcycles, and other vehicle drivers from underestimating the traffic laws, license Plate Recognition Security Cameras come to unleash security and surveillance over cities, thus securing people’s lives and saving grief and money.
If you think that you violate one of the red light traffic or have been speeding on a school area railway, go and check your car photography with the no. of the violation ticket, and the reason for receiving it. Make sure to smile next time when you are passing in the same area, because you will be more than surprised when you notice that these specialized cameras give you the day and date ( specified by time, hr, minute and seconds) of violating one of the traffic laws. Bruch your hair, get tidy dressed, draw a beautiful smile upon your face and drive respectfully to save your soul and that of others.
