Flock License Plate Readers (previously known as Flock Safety Falcon), are a network of AI-powered surveillance cameras that record vehicle data for law enforcement agencies. The system operates in over 6,000 communities across 49 U.S. states, performing over 20 billion vehicle scans monthly.

Taxpayer impact summary

Freedom

Residents and taxpayers have no mechanism to opt out of Flock's surveillance network. The cameras operate 24/7 in public spaces, recording all passing vehicles regardless of consent. Unlike traditional security cameras that may be avoided by choosing different routes, Flock's expanding network of over 40,000 cameras makes avoidance increasingly difficult. The system uses AI to create "Vehicle Fingerprints" that identify vehicles by characteristics beyond license plates, including make, model, color, aftermarket parts, window stickers, and roof racks.

Privacy

While Flock Safety claims their system doesn't violate Fourth Amendment rights because "license plates are not personal information," federal courts have challenged this interpretation. In February 2024, a federal judge ruled that a lawsuit challenging Norfolk, Virginia's use of 172 Flock cameras could proceed, finding that plaintiffs had plausibly alleged the system creates a "detailed chronicle of a person's physical presence compiled every day."

Data collected includes location history that can reveal sensitive information about medical visits, religious attendance, political activities, and personal associations. While Flock states data is deleted after 30 days, contracts grant them "perpetual, worldwide, royalty-free license" to use anonymized data indefinitely. The system shares data across a network of over 4,800 law enforcement agencies nationally.

"Anonymized data"

While Flock defines anonymized data as customer data that is "permanently stripped of identifying details and any potential personally identifiable information" and is rendered so that a person or entity "can no longer be identified directly or indirectly," this definition includes information such as vehicle make, model, color, location patterns, and other non–license-plate attributes.

Privacy researchers caution that mobility datasets labeled as "anonymized" can still be re-identified. A 2013 MIT study found that just four spatio-temporal points uniquely identified 95% of individuals in an anonymized location dataset. Civil liberties organizations such as the EFF and the ACLU note that when detailed travel histories are retained, even without license plates, it is often possible for this data to be linked back to individuals when combined with other data sources.

Business model

Flock operates on a subscription model charging municipalities and law enforcement agencies $2,500 per camera annually plus installation costs. Private businesses including Home Depot & Lowe's also deploy cameras, sharing data with law enforcement. Contracts include automatic renewal clauses and limit municipal oversight capabilities, with cities unable to audit system operations or control how other agencies use shared data.

Market control

Flock Safety has rapidly expanded to become a dominant force in automated license plate recognition, operating in 49 states with over 40,000 cameras deployed. The company's network effect creates pressure for additional jurisdictions to join, as law enforcement effectiveness depends on network coverage. Several states have begun restricting access following privacy violations, with California, Illinois, and New York limiting data sharing after immigration and abortion-related tracking incidents.

Premise of a "license plate camera"

Vehicle Fingerprint technology

These are often referred to as license plate cameras, which creates a fundamental misunderstanding of the product's capabilities.

While marketed as "License Plate Readers," Flock's cameras use what the company calls "Vehicle Fingerprint" technology that tracks vehicles using characteristics beyond just license plates. According to Flock's own marketing materials, the system can identify vehicles even when license plates cannot be captured, advertised as turning "images into actionable evidence — no plate required."

Taken from Flock's marketing materials on their website. Their cameras are advertised as not needing a license plate to work due to vehicle fingerprinting technology; demonstrating that this is far more than just a "license plate camera"

The system catalogs vehicles based on numerous distinguishing features including make, model, color, bumper stickers, dents, damage patterns, roof racks, aftermarket modifications such as wheels or spoilers, window stickers, and even mismatching paint colors. Flock claims this capability is "unique among ALPR systems" & allows law enforcement to search for vehicles based on these characteristics even without a visible license plate.

This technology changes the nature of the surveillance from license plate reading to comprehensive vehicle tracking. A person could still be tracked by the unique combination of their vehicle's physical characteristics. The Electronic Frontier Foundation warns that these "vehicle fingerprints" could flag vehicles based on political bumper stickers, revealing "information on the political or social views of the driver," or economic indicators like rust or damage, potentially "endangering anyone who might not feel the need (or have the income required) to keep their car in perfect shape."

Privacy advocates note that this expanded tracking capability makes the term "license plate reader" misleading, as Flock systems create detailed vehicle profiles that persist even without readable plates. It turns any distinguishing feature of a vehicle into a tracking identifier.

Other Surveillance Products

Flock Aerodome "Drone as First Responder"

Flock Safety also offers an all-in-one drone product which integrates into the Flock AI Surveillance Network as well as local law enforcement's Computer Aided Dispatch software. The Drones are outfitted with live video cameras, thermal imaging, night vision, and potentially other sensors, and are capable of self-launching and self-navigating.^[1] Flock Safety cites following potential use-cases:

Drones are stationed across your service area, ready to respond instantly... Deploy from the dock to geo-coordinates of 911 calls, LPR hits, gunshot detection, or manually by the operator... Control multiple drones and docks with a single operator, providing continuous air support for the entire city.

Rahul Sidhu, VP of Aviation at Flock Safety, works directly with FAA officials and actively lobbies Congress to gain favorable legislation which seeks to expand Flock Safety's surveillance network and further diminish citizen privacy. [2][3][4]

To put it succinctly, flock is now selling a taxpayer funded, self-deploying, single-operator Air Force marketed to individual police departments and cities.

Incidents

False positive incidents (2025)

Held at gunpoint:

In Española, New Mexico, 21-year-old Jaclynn Gonzales and her 12-year-old sister were held at gunpoint and handcuffed after Flock's system mistook a "2" for a "7" on their license plate, falsely flagging their vehicle as stolen.

Law enforcement stalking incidents (2022-2025)

Many documented cases demonstrate abuse of Flock's surveillance capabilities by law enforcement officers:

Cops stalking their ex:

In October 2022, Kechi, Kansas Police Lieutenant Victor Heiar was arrested and later pleaded guilty to computer crimes and stalking after using Flock cameras 228 times over four months to track his estranged wife's movements.

In a separate Kansas incident, Sedgwick Police Chief Lee Nygaard accessed Flock data 164 times to track his ex-girlfriend before resigning after admitting to the misuse.

Abortion & immigration tracking (2025)

In May 2025, Johnson County, Texas sheriff's deputies used Flock's network to track a woman suspected of self-managing an abortion. They were conducting searches across multiple states including those where abortion is legal. The incident led Illinois officials to investigate and subsequently block 47+ out-of-state agencies from accessing Illinois ALPR data.

404 Media revealed over 4,000 searches by local and state police for federal immigration enforcement purposes, despite Flock having no formal ICE contract. A DEA agent was found using an Illinois police officer's credentials to conduct unauthorized immigration searches.

City rejections and terminations (2025)

Multiple cities have rejected or terminated Flock contracts following privacy concerns and effectiveness issues:

0.2% effectiveness rate, low arrests:

Austin, Texas terminated its contract in July 2025 after an audit revealed "systematic compliance failures" and only 165 arrests from 113 million license plate scans (0.2% effectiveness rate).

Denver City Council unanimously rejected a $666,000 contract extension in May 2025 following revelations of 1,400+ ICE-related searches in Colorado data.

San Marcos, Texas voted 5-2 to deny camera expansion after discovering no required audits had been conducted since 2022.

Oak Park, Illinois terminated their contract entirely following the Illinois investigation into illegal data sharing.

Constitutional challenges (2024-ongoing)

In February 2024, Federal Judge Mark Davis denied Norfolk's motion to dismiss a Fourth Amendment challenge filed by the Institute for Justice ( IJ.org ) to the city's use of 172 Flock cameras, comparing the case to Carpenter v. United States regarding warrantless location tracking. Norfolk Police Chief Mark Talbot stated that the cameras were placed so it would be "difficult to drive anywhere of any distance without running into a camera." View the ongoing case details here.

Security vulnerabilities (2024)

The Cybersecurity and Infrastructure Security Agency identified 7 critical vulnerabilities in Motorola ALPR systems similar to Flock's, including hardcoded passwords & unencrypted data storage.
