5 Introduction Product Overview With Automatic License Plate Recognition Server 2 (hereafter referred to as ALPR Server) technology, ACTi now helps you build a smarter surveillance system. ALPR Server is a video analytics software designed to detect and recognize vehicle license plates. Once a license plate is recognized, users can browse through the results, play back footages or export them as evidence or future references. With pre-defined license plate lists, ALPR Server automatically cross-checks if a vehicle entering the area matches its parking permit, and triggers notification to designated recipients, which also enables law enforcement officers to identify suspicious vehicles effortlessly.
