Secret Camera Access? The Hidden Network Tracking America’s Drivers

Across the country, cities are discovering that Flock’s license plate cameras quietly opened a digital back door for federal agencies to track drivers without local consent.

Story Snapshot

Flock’s default “national lookup” tools let outside and federal agencies search local camera data, sometimes without city approval.
Audits in California and Washington found hundreds of thousands of unauthorized searches of residents’ movements.
Federal agencies, including immigration and border authorities, accessed local plate data despite state laws meant to block them.
Dozens of cities have canceled contracts and civil rights groups say the problem is baked into Flock’s business model.

How Cities Discovered Silent Federal Access to Local Camera Data

Mountain View, California offers one of the clearest windows into how Flock’s system reached far beyond what local leaders thought they had approved. A city review found a “statewide lookup” feature running on 29 of 30 cameras for 17 months, even though the police department believed access was limited. During just one year, more than 250 outside agencies ran about 600,000 searches of Mountain View’s plate data, without any separate data-sharing agreements.

City records and reporting show that a separate “national lookup” setting had also been toggled on for at least one camera without the city’s knowledge. Among the agencies found using these tools were the Bureau of Alcohol, Tobacco, Firearms and Explosives, the United States Air Force, and the General Services Administration’s Inspector General. Local officials say they never granted direct access to those federal agencies and moved to terminate the contract after the discovery.

California Cases: When “Nationwide Query” Overrides State Privacy Laws

California law clearly bars public agencies from sharing automated license plate reader data with federal or out‑of‑state law enforcement. Yet an audit in Oxnard found that even with settings locked to “California only,” a vendor-related issue had re‑enabled Flock’s “nationwide query” feature. That glitch allowed agencies outside the state to query Oxnard’s system, violating both department policy and state law, according to the city’s own statement on the incident.

Nearby Ventura County reported a similar problem tied to Flock’s national sharing tools. The Sheriff’s Office said it had disabled National Lookup in June 2023 to follow California privacy rules. A later audit, however, uncovered 364,000 unauthorized accesses between February and March 2025, after the tool somehow reactivated. The office stressed that “no one from our agency activated the national lookup feature,” raising questions about how much real control local departments have over Flock’s network.

Border and Immigration Access Through Lookup Tools and “Informal” Requests

Beyond California, research from the University of Washington Center for Human Rights found that United States Border Patrol had apparent “back door” access to license plate data from at least ten local agencies in 2025. Those departments had not explicitly authorized sharing, yet Border Patrol could search their Flock networks when national or statewide lookup settings were open. The report described this as leaving “the door wide open” for federal tracking of residents’ daily movements.

Civil liberties groups say immigration enforcement has piggybacked on this networked access even where Flock claims not to partner directly with immigration agencies. The Electronic Frontier Foundation highlighted public records showing more than 4,000 national and statewide lookups by local or state police “done either at the behest of the federal government or as an ‘informal’ favor,” often with an immigration focus. That means federal officials did not need their own contract with Flock; they could simply ask a local department to run searches inside this nationwide database.

Nationwide Network Design and Growing Political Backlash

Flock now operates more than 100,000 cameras, feeding plate scans into a cloud system where “national lookup” and “statewide lookup” toggles control cross‑jurisdiction access. Each pass under a camera logs a plate, vehicle details, time, and location, stored for 30 days by default. In at least six documented jurisdictions, federal agencies including Immigration and Customs Enforcement, Customs and Border Protection, the Federal Bureau of Investigation, and the Bureau of Alcohol, Tobacco, Firearms and Explosives reached local data through these lookup tools or via data‑sharing agreements.

So,

Flock is a system of Automated License Plate Readers (ALPRs) that are now in over 5,000 communities with 80k–100k+ cameras across 49 states. Every month, Flock cameras generate over 20 billion vehicle scans (roughly 650–700 million scans per day).

An American Civil Liberties Union analysis argues this is not just a software bug but a business model that assumes broad sharing. Template agreements in some states reportedly give Flock a “worldwide” license to use a department’s plate data for investigative purposes, even when local settings appear locked down. Class action lawyers in California now claim this setup illegally tracks millions of residents and ignores state privacy protections that many voters thought would shield them from mass surveillance.

Flock’s Response and the Open Questions About Who Really Controls Your Data

Flock’s public statements insist that customers “control their sharing relationships” and that the company does not share data without customer authorization except when required by law or emergencies. After the recent wave of audits, lawsuits, and canceled contracts, Flock says it removed federal agencies from National and State Lookup entirely and paused pilot projects with Customs and Border Protection. Company blogs also stress that there is no formal contract with Immigration and Customs Enforcement and that sharing with federal agencies is disabled by default.

Yet city records and state audits continue to show incidents where lookup features were active without local approval, and where federal agencies still gained access through the broader network. That leaves communities across the political spectrum asking the same question: if a private surveillance company can flip a digital switch that lets far‑away agencies watch local drivers, who is really in charge of this data? For many, the answer reinforces a growing fear that powerful networks are being built first, and public consent is being asked later.
