This document provides an overview of a license plate recognition system. It introduces ALPR cameras and their benefits like being cost effective, requiring no human resources, and providing higher accuracy. It then describes how the system works using Matlab, C++, Processing, and Arduino to extract the license plate number from a video, recognize the characters, look up the owner's phone number, and send an SMS notification. The document includes sections on the introduction, why ALPR cameras, how it works, problems faced, and a conclusion.
