Flock Camera: What Flock Safety Cameras Are, How They Work, and the Privacy Debate

You have probably driven past one without noticing. A white box, roughly the size of a large book, mounted on a pole at the roadside. No flashing light. No obvious police markings. Just a quiet, persistent camera recording the license plate of every vehicle that passes.

That is a Flock Safety camera — and as of 2025, there are more than 5,000 law enforcement agencies across the United States using them, along with thousands of private neighbourhood associations, schools, and businesses. The ACLU has called them “creepy ALPR cameras” and launched a dedicated campaign to limit their use. This article explains exactly what they are, how they work, and what the privacy debate means for ordinary people.

What is a Flock Safety camera?

Flock Safety is an Atlanta-based company founded in 2017 that manufactures and operates a network of Automated License Plate Recognition (ALPR) cameras. The company’s cameras are deployed at roadsides, neighbourhood entrances, school driveways, and private car parks to capture still images of every passing vehicle.

Unlike traditional CCTV cameras that record continuous video, Flock Safety cameras capture still photographs triggered by vehicle motion. Each image captures:

• The vehicle’s license plate and state
• The vehicle’s make, model, colour, and body type
• Unique identifiers — bumper stickers, roof racks, tow hitches, body damage, and other distinguishing features
• The exact date, time, and GPS location of the capture

This data is processed by artificial intelligence and uploaded via cellular connection to Flock’s cloud platform, where it becomes searchable by subscribing law enforcement agencies and private customers.

How does a Flock camera network work in practice?

The Flock system operates on a subscription model. Law enforcement agencies pay an annual fee — typically $2,500–$3,500 per camera — and gain access to the Falcon platform, where investigators can search for specific license plates, vehicles matching a description, or patterns of movement over time.

The system works in three layers:

• Capture: The solar-powered roadside camera triggers when a vehicle passes, capturing a still image at high resolution. The camera is optimised for license plate capture in all lighting conditions, including night.
• Processing: Flock’s AI reads the plate and extracts vehicle attributes within seconds. The image and metadata are uploaded to the cloud via an integrated cellular modem.
• Alert: Agencies can set up “hot lists” — databases of plates linked to stolen vehicles, wanted persons, or active investigations. When a matching vehicle passes any camera in the network, the agency receives an instant alert with the location and a photograph.

Flock also operates a feature called “Flock OS” that allows agencies to share data across jurisdictions. A plate captured in one city’s network can trigger an alert in another city’s system if both agencies subscribe and agree to share. By 2024, this inter-agency network covered tens of thousands of cameras across the United States.

Why is the ACLU calling Flock cameras a privacy threat?

The ACLU’s “Get the Flock Out” campaign identifies three core objections to the Flock Safety network:

1. It is mass surveillance, not targeted monitoring. Every vehicle passing a Flock camera is recorded — not just vehicles linked to crimes. In a neighbourhood with multiple camera entry points, a resident’s movements are effectively logged every time they enter or leave. Over 30 days, this creates a detailed record of when someone leaves for work, when they return, who visits, and which routes they use. No warrant, no suspicion, no notification.

2. The data can be shared widely and used in unexpected ways. The Flock platform allows agencies to query each other’s data with minimal oversight in some jurisdictions. Immigration enforcement agencies have access in states that have not restricted it. Third-party requests from outside law enforcement have occurred in documented cases. The ACLU argues that data collected for car theft investigations has been repurposed for unrelated investigations without public knowledge or consent.

3. The accuracy problem creates real risk. Flock Safety cameras can misread plates, and the consequences of a false positive match are not abstract. There have been documented cases of people being stopped at gunpoint or falsely arrested because their correctly-read plate was incorrectly matched against a hot-list entry with a similar plate number. The ACLU’s research identified high false-positive rates in some deployments where agencies did not verify plate data before initiating enforcement action.

How many Flock cameras are there and how do I know if there are any near me?

Flock Safety does not publish a public map of camera locations. However, several independent organisations have attempted to track deployments:

• The Electronic Frontier Foundation (EFF) maintains a partial database of ALPR camera locations through its “Street Level Surveillance” project
• Local journalism and FOIA (Freedom of Information Act) requests have revealed specific deployments in hundreds of US cities and counties
• Some neighbourhood association websites publicly list their camera entry points as a deterrent to would-be criminals

The physical cameras are identifiable once you know what to look for: a white or light grey rectangular housing, typically 20–30cm tall, mounted on existing infrastructure such as utility poles or purpose-built posts. Many are solar-powered with a visible panel. They do not have visible lenses or LEDs — the imaging system is enclosed inside the housing.

In the UK and EU, the equivalent technology uses ANPR (Automatic Number Plate Recognition) cameras operated by police forces. These are governed by stricter data retention rules under GDPR — typically 90 days — and are subject to specific legislation restricting civilian use. Flock Safety itself currently operates primarily in the United States.

Can you opt out of being recorded by a Flock camera?

No. There is no opt-out mechanism for public road recordings in the United States. Flock Safety’s terms allow any vehicle on a public road or visible from public property to be recorded. Covering or obscuring your license plate is illegal under the vehicle codes of all US states.

The only recourse is political: several US states have introduced or passed legislation restricting ALPR data retention periods, limiting which agencies can access the data, and requiring transparency reports. The ACLU campaign specifically supports these legislative efforts and maintains resources for contacting state legislators.

Flock Safety responds to privacy concerns by noting that data is deleted after 30 days by default, that customers own their own data, and that the company provides law enforcement with technology that would otherwise rely on less accurate human methods. The company also points to case studies showing the platform has assisted in solving thousands of serious crimes including murders, kidnappings, and organised vehicle theft rings.

What does Flock Safety mean for how we think about private security cameras?

The Flock debate highlights a distinction that is often blurred in public discussion: the difference between surveillance infrastructure oraz personal security equipment.

Flock cameras are infrastructure — they record everyone by default, their data is pooled across agencies, and the individual has no control over whether they are recorded, how long for, or who accesses the data. The value proposition is collective: communities and law enforcement benefit from the network, while individual privacy is reduced.

Personal security cameras — whether installed on a home, small business, or carried as a body-worn device — operate on an entirely different principle. They are controlled by the owner, the footage stays local unless the owner chooses otherwise, and the scope is limited to the property or person they are intended to protect. There is no data-sharing network, no AI analysis feeding into a law enforcement database, and no third-party access without the owner’s consent.

For homeowners and small business operators who want genuine security without contributing to or depending on a shared surveillance network, covert cameras that record locally to a MicroSD card and do not require cloud connectivity offer a fundamentally different privacy profile. A WiFi clock camera or socket camera recording to local storage is under the complete control of the person who owns and operates it — the polar opposite of a networked ALPR system.

Często zadawane pytania

What does a Flock Safety camera look like?

A Flock Safety camera is a white or light grey rectangular housing, approximately 20–30cm tall, typically mounted on a pole at roadsides, neighbourhood entrance points, or car parks. Many units have a small solar panel attached. The camera lens and imaging hardware are enclosed inside the housing with no visible external lens or light. They are designed to be unobtrusive and are often not noticed by passing motorists.

Does Flock Safety sell to private individuals?

Flock Safety primarily sells to law enforcement agencies, municipalities, homeowner associations (HOAs), schools, and businesses. As of 2025, they do not sell directly to individual consumers. Homeowner associations and private communities can subscribe to the service as an organisation. Individual residents do not have access to the Flock platform independently.

How long does Flock Safety keep license plate data?

Flock Safety’s default data retention policy is 30 days, after which images and associated data are automatically deleted. However, individual agencies and customers can set longer retention periods if their local policies permit. Some law enforcement agencies have set longer retention periods, and state law varies considerably on what is permissible. The ACLU has documented cases where data has been retained beyond stated default periods.

Are Flock cameras legal in the UK?

Flock Safety as a company operates primarily in the United States. The UK uses its own ANPR (Automatic Number Plate Recognition) system, operated by police forces and regulated under the Police and Criminal Evidence Act 1984, the Protection of Freedoms Act 2012, and UK GDPR. Private citizens and businesses can legally operate ANPR cameras in the UK within specific guidelines, but the data handling, retention periods, and access rights are strictly regulated compared to many US deployments.
