How does License Plate Recognition (LPR) Technology work?

LPR technology identifies a vehicle using its license plate only. Since every vehicle carries a unique license plate, no external cards, tags or transmitters need be issued to vehicle owners in order for their vehicle to be recognizable.

The technology is based on unique image capturing and proprietary image processing software, LPRware, developed by Zamir.

The Procedure:
	The Vehicle approaches and imaging sensor recognizes it from the moment it enters its field of view. The Lane Controller’s sensor can take more than one image per vehicle, ability that increases the recognition rates.
	The image is processed in the Lane Control build in Processor. The license plate is extracted from the image, and the digits are separated and recognized.
	The license plate number, together with the image and event information, is stored in the Lane Controller which can also send the information to third party systems and/or activate dry contact (for barriers, alarms etc.).

For network applications the license plate number can now be transferred to a host system, via standard communication protocols (TCP/IP, RS-232, RS-485 etc.).

The InSignia Console, management software was developed by Zamir in order to facilitate access control, security and recording applications. The program contains parking lot and gate databases, authorization databases, terms and limitations of authorized users etc. (Contact us for more information).

The Zamir system includes multiple relays for controlling external devices such as gates, signals and signs, drawn from data entered into the InSignia Console program.
