Flock Cameras: How License Plate Recognition Technology Works in 2026

If you drive in the United States, you may have passed a Flock camera without noticing. These small cameras are often mounted on poles near roads, in parking lots, and at the entrances to neighborhoods. Police departments, cities, and private groups use them to help find stolen cars and solve crimes. At the same time, a growing number of residents and city leaders are asking hard questions about privacy.

In this guide, we explain in simple words what Flock cameras are, how they work, what they cost, what supporters and critics say, and what you can do if you want to learn more about the cameras in your own town. We try to be fair to both sides and to say clearly which claims come from the company and which come from other sources.

Please note: this is general information, not legal advice. Prices, policies, and laws change quickly, so please check current local information.

What Are Flock Cameras?

Flock Safety is a company based in Atlanta that sells camera systems and software to police departments, cities, businesses, and neighborhood groups. Its best-known product is an automated license plate reader, often shortened to ALPR or LPR.

An ALPR camera takes photos of passing vehicles. Software then reads the license plate and records details about the car. According to Flock, the camera can note the plate number and state, the vehicle’s make, color, and type, and other details such as roof racks or bumper stickers. The company calls this its “Vehicle Fingerprint” feature. Flock also says the system can check plates against national crime databases for stolen vehicles, wanted persons, and missing persons, and send an alert to police.

Flock says its cameras do not use facial recognition and that they focus on vehicles, not on the people inside them.

Flock also sells other products, such as video cameras, software that works with a customer’s existing cameras, and gunshot detection. In this article, we focus mostly on the license plate cameras, because they are the center of most public debate.

How Do Flock Cameras Work?

Here is the process in simple steps.

1. A car drives past a camera. The camera takes a picture of the vehicle.
2. Software reads the image. It finds the license plate and notes the car’s features.
3. The data is stored in the cloud. The record usually includes the image, the time, and the location of the camera.
4. The system checks for alerts. If a plate matches a stolen car or another case in a crime database, police can get a notice.
5. Police can search later. During an investigation, an officer can search the stored data to look for a vehicle, for example one linked to a crime.

Many cameras can be placed across a city or region. When data from many cameras is connected, police may be able to see where a vehicle was seen over time. That is both why supporters like the system and why critics worry about it.

Who Uses Flock Cameras?

According to a February 2026 NPR report carried by public radio stations, Flock has contracts with more than 5,000 law enforcement agencies. The same report says a crowd-sourced map called DeFlock.me had located more than 76,000 license plate readers across the country, though the map is not an official count.

Besides police, homeowners associations, businesses, and neighborhood groups also buy these cameras to watch their entrances and parking areas.

What Do Flock Cameras Cost?

Flock does not publish its prices on its website, so most public price information comes from government contracts and third-party guides. The numbers below come from a pricing guide published by a competing company, which says its figures are based on a public cooperative price list and city purchase records from July 2026. Because the source is a competitor and the page does not link to the original records, please treat these as estimates and ask for a current quote.

• Standard license plate camera: about 3,000 US dollars per camera per year, leased
• Installation: a one-time fee, roughly 150 to 1,900 dollars depending on the site (about 650 dollars for a standard install, and more if a new pole and solar power are needed)
• Movable camera: about 3,500 dollars per camera per year, with no install fee
• Video camera: about 3,000 dollars per year, plus an install fee
• Software for a customer’s own cameras: about 1,500 dollars per camera per year
• Gunshot detection: about 12,000 to 35,000 dollars per year, depending on the area covered

The lease generally covers the hardware, the connection, cloud storage, software, and maintenance. The customer does not own the camera, and Flock removes it when the contract ends. Contracts are often annual, with better prices for longer terms. The same guide suggests adding about 15 to 25 percent for poles, electrical work, and permits, though it does not give a clear source for that figure.

Costs add up quickly. A city with dozens of cameras can spend well over 100,000 dollars a year. One example from the NPR report is Flagstaff, Arizona, whose contract covered 36 cameras.

What Supporters Say

Supporters, including many police departments and some neighborhood groups, point to several benefits.

• Finding stolen vehicles. Cameras can alert officers when a stolen car passes by.
• Solving crimes. Investigators can search for a car seen near a crime and follow leads they might not have had otherwise.
• Finding missing people. Alerts can help locate a missing person or a vehicle linked to an emergency.
• Helping small departments. Cameras can act as an extra tool when there are not enough officers.
• Deterrence. Some believe visible cameras make criminals think twice.

Flock’s own website lists many local success stories and crime-reduction numbers, for example drops of 34 percent in Marietta and 70 percent in San Marino, California. These are company claims. The page does not show how the numbers were measured or whether other factors played a part, so they do not prove that the cameras alone caused the changes. Independent studies of license plate readers can be hard to compare and often reach mixed results, so it is wise to read research from universities and independent groups, not only company materials.

What Critics Say

Critics, including civil liberties groups such as the ACLU and the Electronic Frontier Foundation (EFF), raise several concerns.

1. Tracking Over Time

One camera takes a picture. But a network of many cameras can build a searchable history of where a car has been. Critics say this can reveal sensitive details, such as where someone lives, works, worships, or seeks medical care, even if the person has done nothing wrong.

2. Data Sharing

A key concern in 2025 and 2026 has been how data is shared between agencies. The NPR report says some cities found that their data had been shared more widely than they knew, and that federal agencies had searched it. Audit logs in some places showed local police running searches for federal agencies, sometimes with “ICE” or “immigration” listed as the reason.

3. Misuse by Individuals

The ACLU and other groups point to cases where people with access have been accused of using the systems for personal reasons, such as tracking someone they know. Critics argue that police departments, not judges, usually control who can search.

4. Legal Questions

The ACLU and EFF challenged the use of Flock cameras in Norfolk, Virginia. In April 2026, the Virginia Court of Appeals ruled that police did not need a warrant to get the vehicle-location information involved in that case. The court’s reasoning focused on that particular system and the fact that the cameras captured vehicles on public roads. This does not mean Flock cameras have been ruled lawful everywhere, and the legal debate continues.

5. Trust and Transparency

Some cities say they lost trust after learning about data-sharing details they had not been told. In August 2025, Flock admitted to a pilot program with U.S. Customs and Border Protection, after its CEO had earlier denied federal contracts. The CEO later said the company had “clearly communicated poorly.”

What Flock Says About Privacy

Flock has answered many of these concerns. According to the company’s own statements:

• It does not use facial recognition.
• Customers own their data, and Flock does not sell it.
• Every search must have a stated reason, and searches are logged in an audit trail.
• Data is encrypted and, by default, deleted on a rolling basis. A company blog says the default is 30 days. A more recent news report says Flock is reducing its default to seven days, with longer storage allowed when data is saved as evidence. Because policies change, ask your local agency what retention period it actually uses.
• Customers must use an auditing tool that flags unusual searches, and each search must be tied to a case code.
• It ended its federal pilot programs, removed federal agencies from state and nationwide lookup networks, and says ICE has no direct access to its platform.
• It added filters that block some immigration and reproductive-health terms where state law prohibits those searches.
• Cities control their own sharing settings.

Critics reply that these steps came after public pressure and that stronger independent oversight is still needed. The company’s CEO has also acknowledged that Flock got some things wrong in the past.

Why Some Cities Are Canceling

According to the NPR report, at least 30 localities had turned off cameras or canceled contracts since the start of 2025. Examples include:

• Flagstaff, Arizona, where the council voted to end a contract for 36 cameras even after the police reduced data sharing and cut retention from 30 to 14 days.
• Santa Cruz, California, where the council voted in January to end a contract for eight cameras after concerns about unauthorized sharing found in audits.
• Hillsborough, North Carolina, which ended its relationship in October 2025 because of contract language that could allow data to be given to third parties.
• Staunton, Virginia, and others.

Flock says that new agency partnerships significantly outnumber the cancellations. So the picture is mixed: some places leave, while others continue to buy.

Are Flock Cameras Safe?

The cameras themselves are ordinary electronic devices and are not known as a health danger. The real questions are about public safety benefits and privacy risks. Any system that stores sensitive data can be misused or hacked. Flock says it uses strong encryption and audit logs, while critics point out that misuse often comes from people with legitimate access, so rules, audits, and penalties matter. Supporters say the cameras help protect communities from crime, and critics say data about movements can put vulnerable people at risk if it is shared in unexpected ways.

The honest answer is that benefits and risks depend on how the cameras are used, who can access the data, how long it is kept, and how strong the oversight is.

Questions to Ask Your Local Government

If cameras are used or planned in your area, these questions can help you understand the policy:

1. How many cameras are installed, and where are they?
2. What is the contract cost, and for how long?
3. How long is the data kept?
4. Who can search the data, and for what reasons?
5. Is data shared with other agencies, including outside the state? If so, which ones?
6. Are federal agencies allowed to search it, directly or through a local officer?
7. Are the audit logs public? Who reviews them?
8. What is the penalty for misuse?
9. Can the city cancel the contract easily, and who owns the data afterward?
10. Is there independent evidence that the cameras reduce crime in this community?

Many cities publish their policies and contracts, and you may be able to request records through your local public records process. Some Flock customers also use a public “transparency portal” that shows basic details about their cameras and policies.

Frequently Asked Questions

What are Flock cameras? They are cameras, mostly license plate readers, that photograph passing vehicles and use software to read plates and note vehicle details.

Do Flock cameras use facial recognition? Flock says no. The cameras focus on vehicles.

How much do Flock cameras cost? Flock does not publish prices. One pricing guide estimates about 3,000 dollars per camera per year plus installation, but treat this as an estimate and ask for a current quote.

How long is the data kept? Flock’s blog says 30 days by default, and a recent news report says it is moving to a seven-day default. Local agencies may choose their own settings, so check with your city.

Who can see the data? Authorized users at participating agencies can search it, and searches are supposed to be logged with a reason. Sharing settings are controlled by each customer.

Can I find out if there are cameras in my area? Check your city’s website or public records, and look for a transparency portal. Crowd-sourced maps exist, but they are not official.

Are the cameras legal? It depends on the state and the case. One Virginia appeals court decision in 2026 allowed police to get certain vehicle-location data without a warrant in a specific case, but the legal debate continues and laws vary by state.

Do Flock cameras reduce crime? The company reports crime reductions in several places, but these are company claims without detailed methods. Independent research is mixed, so look for local, third-party evidence.

Why are some cities canceling contracts? Reasons include privacy concerns, worries about data being shared with federal agencies, and a loss of trust after audits showed wider sharing than expected.

Final Thoughts

Flock cameras show a common modern question: how do we use technology to improve safety without giving up too much privacy? Supporters see a useful tool that helps find stolen cars and solve crimes. Critics see a growing network that can track ordinary people and be misused.

The most useful path for communities is clear rules, honest reporting, and independent oversight. Know what is collected, how long it is kept, who can search it, and who checks the searches. When those answers are public and strong, residents are in a better position to decide whether the cameras are worth the cost.
