ALPRs: Who's Paying for Them?
The short answer is you, the taxpayer.
The explosive growth in automatic license plate readers (ALPRs) has caught many communities off guard. This is especially true as details about their capabilities far beyond simply flagging stolen vehicles become widely known. Yet few citizens stop to ask the foundational question: who is paying for this rapid expansion?
As the old saying goes, whenever in doubt, follow the money.
Background on ALPR Technology
ALPR technology is not new. Law enforcement agencies began adopting early systems in the late 1990s and 2000s. Adoption grew steadily, particularly among larger metropolitan departments:
- By 2009: Over one-third of law enforcement agencies with 100 or more officers used ALPRs (Source).
- By 2016: Roughly two-thirds to three-quarters had direct access to ALPR data (Source PDF).
- By 2020: Around 72% of large agencies deployed ALPRs regularly (Source).
For two decades, rollouts remained gradual. Systems were expensive, hardware-intensive, and primarily mounted on patrol vehicles or major highway gantries. High capital costs kept the technology out of reach for most smaller towns and rural jurisdictions until the business model shifted around 2020.
The Surge: Flock Safety and Networked Expansion
The shift from isolated deployment in major cities to thousands of interconnected cameras scanning billions of plates monthly was driven largely by Flock Safety. Flock disrupted the market by introducing a low-cost, hardware-as-a-service subscription model: minimal upfront costs, annual per-camera fees, and seamless cross-jurisdictional data sharing through their TALON network.
Flock’s rapid growth trajectory mirrors the overall market expansion:
- Pre-2020: Limited pilot programs in homeowners associations (HOAs) and select law enforcement units.
- 2020–2021: Rapid acceleration. Spikes in violent crime and auto thefts during the COVID-19 pandemic fueled public and political demand. Flock expanded to roughly 1,400 cities.
- 2022–2023: Deep market penetration. By early 2023, Flock operated in over 2,500 communities across 42 states.
- 2024–2026: Massive national scale. By 2024, networks spanned 4,000 cities and 80,000+ cameras. Today, coverage exceeds 5,000 communities across 49 states, generating over 20 billion vehicle scans monthly for an estimated $300 million in annual subscription revenue.
While Flock is the most visible brand due to its distinct hardware, competitors like Motorola Solutions (Vigilant), Genetec (AutoVu), Rekor Systems, PlateSmart, Axis Communications, Hanwha, Avigilon, Bosch, and Jenoptik operate similar models.
Civil liberties groups like DeFlock now map nearly 100,000 public and private ALPR cameras nationwide. This unprecedented surveillance footprint raises deep privacy questions. Yet the public rarely scrutinizes where the capital comes from.
Federal Grants, Vendor Trials, and Off-the-Books Funds
As highlighted by the Electronic Frontier Foundation (EFF) in “Free” Surveillance Tech Still Comes at a High and Dangerous Cost, agencies draw from a complex tapestry of federal grants, alternative local revenue, and public-private partnerships to finance their networks.
1. Federal and State Grant Programs
Most ALPR networks are seeded with federal funds. Because the technology sits at the intersection of traffic enforcement, counter-terrorism, and drug interdiction, departments draw from multiple grant pools:
- Department of Justice (DOJ): The Edward Byrne Memorial Justice Assistance Grant (JAG) program is a primary funding pipeline for agency technology hardware (BJA JAG Overview; Example: JAG ALPR Funding).
- Department of Homeland Security (DHS): Programs like the Urban Area Security Initiative (UASI) fund ALPR networks under the banner of critical infrastructure protection (SoundThinking Grant Guide).
- Department of Transportation (DOT): Through National Highway Traffic Safety Administration (NHTSA) grants intended for road safety, federal highway dollars flow to police agencies. These funds frequently support multi-purpose surveillance gear (ACLU DOT Investigation).
2. Discretionary and Alternative Local Revenue
When initial grant cycles end, agencies turn to local funding mechanisms that often bypass city council votes or public ballot measures. As Flock notes in its guide, How to Fund a License Plate Reader (LPR) Program: 7 Funding Sources, alternative channels include:
- Asset Forfeiture Funds: Cash and property seized during law enforcement operations directly fund equipment purchases. This creates a self-sustaining loop: forfeiture funds buy cameras, which then generate additional traffic stops and seizures.
- Jail Commissary Revenues: Sheriffs frequently control profits from jail commissaries (commissary sales, phone fees, hygiene products). These discretionary accounts allow rapid network rollouts with minimal administrative oversight.
- Dedicated Local Taxes: Cities often allocate portions of local sales taxes, cannabis excise taxes, or hospitality fees directly to specialized law enforcement funds.
3. Public-Private Partnerships and Crowdfunding
Private entities play an increasing role in expanding public surveillance capabilities:
- HOAs and Business Improvement Districts: Property associations, corporate campuses, and commercial plazas purchase and maintain their own camera networks.
- Network Integration: Private owners routinely link their feeds into local police departments or regional hotlists. This expands law enforcement surveillance footprints into residential neighborhoods at zero initial cost to local government.
4. General Funds: The Ultimate Handoff
While alternative funding gets programs running without public friction, long-term operational costs eventually transition to the municipality's core operating budget. Once an agency demonstrates metrics like stolen vehicle recoveries, local leaders are persuaded to absorb recurring subscription fees into the annual general fund.
Once a surveillance subscription hits the general fund, public visibility drops. And that is precisely where the privacy debate begins.
The Public Cost: Privacy, Oversight, and Accountability
As awareness of ALPR density grows, a broad coalition of legal advocacy groups, constitutional scholars, and community organizations are raising critical alarms regarding mass surveillance, warrantless location tracking, extended data retention, and potential chilling effects on public assembly.
- Institute for Justice (IJ): Leading constitutional challenges through its Plate Privacy Project, IJ litigates Fourth Amendment claims against broad, warrantless camera networks in cities like Norfolk, VA, and San Jose, CA. Their work highlights how camera errors lead to dangerous wrongful detentions and argues for strict warrant requirements to access historical travel data.
- ACLU: Through initiatives like the "Get the Flock Out" Toolkit, the ACLU partners with community coalitions to oppose unmonitored deployments, draft protective model legislation, and file constitutional challenges over data sharing between local police and federal entities like ICE.
- Electronic Frontier Foundation (EFF): Providing technical analysis and investigative reporting on Flock’s broader ecosystem, the EFF documents cases of misuse, tracks surveillance density via the Atlas of Surveillance, and advocates for strict municipal oversight and mandatory data deletion windows.
Legal advocacy groups continue to challenge these systems in court, but the ultimate authority rests with the taxpayers funding these contracts.
Taking Action in Your Community
Citizens seeking accountability can engage directly at the local level:
- Attend City Council Meetings: Ask officials if local ALPR contracts require independent privacy impact assessments and mandatory audit logs.
- Examine Funding Sources: Demand transparency on whether initial capital or recurring fees draw from federal grants, asset forfeiture, or general municipal tax dollars.
- Push for Strict Guardrails: Advocate for binding policies requiring warrants to search historical movement data, restricting third-party data sharing, and establishing short data-retention windows (for example, deleting non-flagged scans within 30 days).
There is no expectation of total anonymity on public roads. However, the automated, continuous tracking of every vehicle journey stored in commercial databases and analyzed at scale represents a fundamental shift in public oversight. If taxpayers do not demand transparency from local leaders, this automated network will continue expanding on the public's dime.
Remember: We may not have anything to hide, but everything to protect.
