What is Flock, and why is it photographing your car?

If a slim camera on a black pole has appeared at the entrance to your neighborhood or at an intersection you drive through, there is a good chance it belongs to Flock Safety, and a good chance nobody asked you before it went up. This page explains what the system is, what it was built to do, how it gets abused, and what communities across the country are doing about it. Everything here links to sources or to incidents we have documented ourselves.

The short version

• Flock Safety operates the largest license plate reader network in the United States, built in under a decade by a single private company.
• The cameras photograph every vehicle that passes, not vehicles suspected of anything.
• The system logs far more than plates: it builds what the company calls a vehicle fingerprint from your car's physical details.
• The data is searchable across agencies and state lines, in most situations without a warrant.
• Documented abuse is not hypothetical. It ranges from officers tracking ex-partners to federal agencies searching local data that no local official approved. We catalogue these cases as they happen.

Where Flock came from

Flock Safety was founded in Atlanta in 2017, and its first customers were not police departments. They were homeowners associations that wanted to know when an unfamiliar car entered the subdivision. The company made the hardware cheap, wireless, and solar powered, and then did the thing that changed everything: it networked the cameras together. What began as a gated-community product became law enforcement infrastructure, and by the company's own materials it now operates in thousands of communities across 49 states. By mid-2026, industry trackers put the network past 100,000 active cameras, which makes it, by camera count, the largest surveillance network in the country, assembled with no national debate and no vote.

What the cameras actually capture

Each camera is motion activated and photographs every vehicle that passes it, day and night, across multiple lanes. The system is not a simple plate reader. Machine learning extracts and indexes the details of the vehicle itself:

Every read is timestamped and stored, typically for thirty days, though retention is a setting each agency chooses. Because the network is shared, a detective in one state can search reads captured in another, in most situations with nothing more than a login and a typed-in reason. No warrant is required under most current court rulings, because the photographs are taken in public.

The company has also expanded well past plate reading: audio sensors marketed for gunshot detection, general video surveillance, and drones that launch from rooftop docks in response to 911 calls. The company now markets those drones beyond policing, to retailers, hospitals, and warehouses.

What they claim it was built for

The honest version of this page includes the pitch, because the pitch is real. Plate readers help recover stolen vehicles, locate cars connected to abductions and AMBER Alerts, and find missing and endangered people. Flock cites recoveries of abducted children, and one Massachusetts police chief has described using a camera to find a man in time to stop his suicide. For a small department, the system is sold as a force multiplier: the investigative reach of a force several times its size, for the price of a subscription.

Those outcomes happen, and they are why this debate is not simple. The question this site exists to document is not whether the technology can do good. It is what else happens when a searchable record of everyone's movements exists, and the rules governing it are an afterthought.

How it gets abused

People with logins

The most common documented abuse requires no hacking. It is authorized users running searches on people who were never suspects: ex-partners, estranged spouses, acquaintances. These cases surface in audit logs when anyone thinks to look, and they end careers and produce criminal charges when they do. We have documented officers disciplined, fired, charged, and jailed for exactly this, and new cases appear in our coverage steadily. The tool works as designed in every one of these cases. That is the problem.

Data flowing where nobody approved it

In 2025, reporting by 404 Media and an audit by the Illinois Secretary of State revealed that federal agencies had been searching local Flock data on a scale local officials never knew about. U.S. Customs and Border Protection had access to tens of thousands of cameras through a pilot program. Records obtained by journalists and a U.S. Senate inquiry showed immigration authorities, the Secret Service, and Navy investigators running searches through local networks, and local officers in several states running lookups on federal immigration agencies' behalf.

The city of Evanston, Illinois became the emblem of the problem. After the state audit found camera data had been accessible to CBP in violation of Illinois law, the city deactivated all nineteen of its cameras and terminated its contract. Flock then reinstalled cameras without the city's authorization, and Evanston responded with a cease and desist letter and covered the cameras in plastic until they came down. Flock has since said it does not work with ICE or its parent agency and has restricted out-of-state access to cameras in several states. The pattern that remains is the point: the data went where no local official approved, and the public found out from journalists, not from the company or the police.

The structural problem

Retention periods, who can search, what counts as a valid reason, and which outside agencies get access are all settings and policy choices, made quietly and changeable at any time. There is no federal statute governing any of it. A community's protection is whatever its local contract and policy say, which is why we publish a guide to requesting those documents for your own town.

What people are doing about it

The backlash is real, organized, and growing on several fronts at once.

• City councils are voting. Dozens of cities have suspended, cancelled, or declined Flock contracts after public pressure, audits, and the federal access revelations. Others have voted to switch vendors instead, most often to Axon, which is why we maintain a dedicated Axon section: replacing the logo on the camera does not end the surveillance or answer a single oversight question.
• Volunteers are mapping the network. Projects like DeFlock crowd-map camera locations so residents can see the infrastructure instead of driving past it blindly. Flock sent the project's creator a cease and desist letter over the name; the Electronic Frontier Foundation took the case without charge, called the demand groundless, and the map is still online.
• Partnerships collapsed under scrutiny. In February 2026, Amazon's Ring cancelled a planned integration that would have let police request doorbell footage through Flock's system, days after a Super Bowl ad put Ring's police ties in the spotlight. The companies described the cancellation as a joint logistical decision; the public pressure surrounding it was plain either way.
• Some people are cutting cameras down. Across the country, cameras have been spray painted, disabled, and removed from poles. We document that vandalism in our archive the same way we document everything else, as reported incidents with sources. We do not encourage it. Destroying a camera is a crime, it hands the company a sympathetic story, and the camera comes back. Council votes have taken down more cameras than bolt cutters have.
• People are showing up to meetings. The contracts live in city councils, and public pressure has flipped votes. Our events page tracks hearings, council votes, and community meetings, and the states section shows what is operating where you live.

The company has responded to the pressure: in 2026 it announced audit tools and shorter recommended retention windows. Whether announcements become enforceable limits is exactly what the public record will show, and we will keep documenting it either way.

The network was built without a vote. The record of how it is used is being built by people paying attention.

What you can do

• See whether cameras operate near you on DeFlock's public map, and check your state's page for what we have documented there.
• Request your town's contract, policy, and audit logs. Our guide includes a ready-to-send template.
• Attend the council meeting where the contract comes up. Find meetings near you, or submit one.
• Follow the documented incidents and the full archive, and send us contracts, audit logs, and local reporting from your community.

Common questions

What is a Flock camera?

A solar powered, motion activated license plate reader, usually on a slim black pole at an intersection or neighborhood entrance. It photographs every vehicle that passes and logs the plate plus the vehicle's physical details, feeding a network searchable by thousands of law enforcement agencies.

Does Flock record video?

The core plate readers capture still images, not continuous video. The company separately sells audio sensors marketed for gunshot detection, video surveillance cameras, and drones that launch automatically in response to 911 calls.

How long does Flock keep license plate data?

Retention is a setting each agency chooses, commonly thirty days by default. The number for your town lives in its contract and policy, which are public records you can request.

Who can search the data?

Authorized users at the agency that owns the cameras, and users at other agencies in the network where sharing is enabled, including out of state. In most situations no warrant is required under current court rulings. The documented abuse on this page happened through exactly these channels.

How do I find Flock cameras near me?

DeFlock's public map crowd-sources reported camera locations nationwide. For what the cameras have led to where you live, our state pages track documented incidents, agencies, and contracts.
