LPR cameras are high-speed cameras which contains an interface with specialized computer software which is used to read the license plate numbers in the vehicles. These cameras will take a picture of the front and rear plates of the vehicle and further convert those images into computer readable data. LPR cameras are ideal for electronic toll collection, monitor border crossings, gas filling stations, traffic management, drive through customer recognition, stolen car identification and vehicle tracking etc.
LPR makes monitoring lots and vehicles more efficient and thus reduces departmental overhead. This allows the department to control parking-related costs and increase usage efficiency. A major difference between a normal CCTV and a LPR is that intelligent traffic modes built into these cameras which allow the camera to compensate for speed, weather, and headlight issues which all make it challenging to capture a usable video that identifies license plates. The number plate image which is captured with LPR HD with Night vision feature is 70 Pixels and it normally uses verifocal lens. These cameras are very much useful for Weigh bridge application too by tracking trucks as they come and go from the warehouse to monitor deliveries and pick ups.
LPR cameras are considered to be a cost-effective choice than some alternatives, like embedding transponders in cars to track them. The software technology used to back up LPR cameras is very much improved from earlier versions. In addition, LPR cameras save law enforcement manpower, because law enforcement officers no longer need to go through every single suspicious picture by hand, or lie in wait at stoplights for traffic law violators. In future possibilities are there to implement this on all signals.
