Automated License Plate Readers (ALPR)

An Automated License Plate Recognition (ALPR) System is a searchable computerized database resulting from the operation of one or more fixed cameras combined with computer algorithms to read and convert images of registration plates and the characters they contain into computer-readable data (CA Civil Code §1798.90.5(d)). ALPR technologies will assist the Monterey Police Department (MPD) in locating vehicles that have been used in violent crime, retail theft, and other criminal activity. ALPR technologies have addressed privacy concerns by creating systems that are intended to identify vehicles, license plates, and/or makes and models of vehicles, but not vehicle occupants. The ALPR system would not capture personally identifiable information; it would only capture the images and license plates already visible in public.

In addition to the procurement of a fixed ALPR camera system, MPD patrol vehicles are currently equipped with an in-car ALPR system that could be activated and will work in conjunction with a fixed ALPR system. A mobile ALPR system scans and captures license plates from cameras mounted on police vehicles. A fully functional fixed and mobile ALPR program that provides cameras placed at strategic locations throughout the City and in vehicles will add significant investigative leads to help solve and deter crime in Monterey. Technological advancements assist in all endeavors, including detecting and deterring crime.

There are numerous existing state legislative mandates for public agencies that operate ALPR systems. These state legislative mandates will be addressed in MPD Policy 433 – Automated License Plate Readers.

Many communities in Monterey County are utilizing ALPR technology and finding success in apprehending suspects and deterring crime. In Monterey County, the following agencies are utilizing ALPR technology: Carmel-by-the-Sea, Pacific Grove, Seaside, Sand City, and Salinas.

An investment in a fully functional ALPR solution will ensure the City is equipped with technology that can help to identify vehicles associated with criminal activity, thus deterring and helping to proactively suppress crime and reduce the fear of crime in Monterey.
