Flock Safety ALPR cameras: the government contracts behind the cameras on your street

Flock Safety does not sell cameras to police departments. It leases them. A city or county signs a multi-year agreement, typically two to five years, and pays an annual fee per camera. That fee covers the hardware, the software platform called Flock OS, technical support, and access to what Flock calls the national network: the ability to query license plate data collected by cameras operated by other agencies across the country.

The lease structure has a specific consequence for public records law. The cameras are Flock property, not city property. The software is Flock's. The data is collected by Flock's infrastructure. But the contract between the police department and Flock is a government contract, negotiated by a public agency, paid with public funds, and therefore subject to public records disclosure in every state. Flock contracts obtained through public records requests in California, Indiana, Minnesota, Oklahoma, South Carolina, and other states have revealed provisions that were not disclosed to city councils when the contracts were approved.

In Benicia, California, documents obtained through a public records request revealed that the city was billed for a camera it had not yet installed, because Flock's billing is triggered by the first camera in a contract, not by each camera individually. In Bloomington, Indiana, the city withheld Flock contracts for over a year in response to multiple public records requests, initially claiming that releasing an order form would create a reasonable likelihood of threatening public safety by exposing a vulnerability to terrorist attack. Indiana courts disagreed.

Flock cameras are sold to police departments primarily on a traffic safety and crime-solving justification. The cameras are mounted on public roads, the argument goes, and public roads carry no expectation of privacy under existing Fourth Amendment doctrine. A license plate is visible. A public road is public. The cameras document what is already observable.

That argument weakens when the camera is not on a road. Flock cameras appear in city park parking lots, at public basketball courts, in apartment complex driveways, and in other locations where the traffic-safety rationale does not apply and the non-roadway placement receives less public notice and less permitting scrutiny than a road installation. In South Carolina, the state Department of Transportation discovered more than 200 Flock cameras installed on state roads without the required encroachment permits in 2024.

A non-roadway camera is still governed by the same city contract as the roadway cameras. The contract specifies where cameras may be placed. Whether the contract requires city council approval for each placement, or delegates placement authority to the police department or to Flock directly, is language that appears in the contract and that most residents never see. The records request gives you that language.

In 2024, a trial court evaluating a challenge to a city's Flock network described the system as functioning as a dragnet over the entire city and compared it to the practice of placing GPS trackers on every vehicle in the jurisdiction, a practice the Supreme Court addressed in United States v. Jones (2012). The court's concern was not any single camera but the cumulative effect of the network: every trip, every route, every destination, logged and searchable without a warrant.

In January 2026, a federal judge in Norfolk, Virginia ruled that the city's Flock camera network did not yet rise to a constitutional violation, while explicitly warning that ALPR surveillance could become too intrusive and run afoul of constitutional privacy standards at some point as the technology expands. The ruling allowed a lawsuit filed by the Institute for Justice to proceed.

The Supreme Court's 2018 decision in Carpenter v. United States established that long-term collection of location data is categorically different from simple record-keeping and that the third-party doctrine, which holds that information shared with a third party carries no Fourth Amendment protection, does not apply when the collection is comprehensive enough to reveal a person's patterns of life over time. The courts have not yet applied Carpenter directly to ALPR networks, but multiple ongoing cases are testing that question.

The Flock OS platform allows participating agencies to query the license plate data of other agencies in the network. A police department in one city can search plates collected by cameras in another city, county, or state, without a separate warrant or a separate data-sharing agreement with that specific agency. The scope of that cross-agency access is defined by the master contract and by Flock's platform terms, not by bilateral agreements between police departments.

An analysis by the Virginia Center for Investigative Journalism found that before Virginia's data-sharing restriction took effect in July 2025, federal agencies attempted to access local Virginia Flock data thousands of times for immigration enforcement purposes. The ACLU and Electronic Frontier Foundation sued Marin County, California for sharing ALPR data with ICE and CBP without a lawful basis. Cambridge, Massachusetts removed sixteen Flock cameras after the city determined that federal data-sharing terms were not compatible with the city's sanctuary policies.

Whether your jurisdiction's Flock contract limits federal access, and under what conditions, is language that appears in the contract. The audit log, which shows who searched your plate and when, may or may not be accessible to you depending on how the contract configures Flock's transparency portal.

This page establishes that Flock Safety cameras are governed by public contracts, that those contracts have been obtained through public records requests in multiple states and have revealed billing irregularities, placement disputes, data-sharing provisions, and federal access terms that were not disclosed to city councils or residents when the contracts were signed. It establishes that courts are actively examining whether the cumulative effect of these networks violates the Fourth Amendment, and that multiple cities have suspended or terminated Flock contracts in 2025 and 2026 over unresolved privacy and data-sharing concerns.

This page does not establish that Flock cameras are illegal. Current federal court doctrine, as of this writing, holds that cameras recording publicly visible license plates on public roads do not by themselves constitute a Fourth Amendment violation. The legal question being actively litigated is whether the network effect, the comprehensive and persistent tracking that no single camera produces but that the full system enables, crosses a constitutional line. That question is not yet resolved.
