What are ALPRs

Automated License Plate Readers (ALPRs), sometimes called Automatic Number Plate Recognition (ANPR), are high-speed, computer-controlled camera systems that capture and analyze data from the license plates of passing vehicles. These systems use a combination of hardware—cameras that can be fixed on poles or mounted on vehicles—and sophisticated software, often employing Optical Character Recognition (OCR) algorithms, to translate license plate characters into machine-readable data.

ALPRs automatically capture license plate numbers along with the date, time, and GPS location of each capture. Some advanced systems can also record other vehicle characteristics like make, model, color, and even distinguishing features such as bumper stickers or damage. These systems are primarily used for security, surveillance, traffic management, toll collection, and locating stolen or wanted vehicles.

What is Flock Safety?

Flock Safety is a company that manufactures and operates specialized security hardware and software, with a primary focus on ALPR systems. What distinguishes Flock from traditional law enforcement ALPRs is its business model: the company markets its cloud-connected cameras not only to police departments but also to neighborhood associations and private property owners, creating a sprawling, interconnected surveillance network.

Unlike some targeted ALPR systems that discard data when there's no match against a watch list, Flock systems stream footage to off-site servers where it is processed, analyzed, and added to a growing cloud database—recording the movements of nearly every vehicle that passes. The system automatically checks captured plates against hot lists, including the National Crime Information Center (NCIC) database, for alerts on stolen vehicles, missing persons, or vehicles linked to outstanding warrants.

Flock also emphasizes its proprietary "Vehicle Fingerprint Technology," which allows users to search for vehicles based on characteristics beyond the license plate—such as make, model, and color—even without a plate number. Data is typically retained for 30 days before automatic deletion, though this retention period can be extended by local policy.

Flock in Orange County, California

Flock Safety cameras have been rapidly adopted across Orange County. Multiple cities and law enforcement agencies in the region have contracted with Flock to deploy ALPR cameras throughout their jurisdictions, often with little public notice or debate. Homeowners associations in Orange County have also installed Flock cameras in residential neighborhoods, contributing to a dense web of surveillance that tracks vehicle movements across the county.

This proliferation means that as you drive through Orange County—whether commuting through Irvine, visiting family in Anaheim, or shopping in Costa Mesa—your license plate and vehicle details are likely being captured, logged, and stored in Flock's cloud database multiple times per day. The resulting dataset creates a detailed record of residents' movements that can be searched and analyzed by law enforcement agencies and, in some cases, shared across jurisdictions.

For Orange County residents concerned about privacy and civil liberties, understanding how these systems operate—and how extensively they've been deployed in your community—is the first step toward meaningful oversight and accountability.
