Flock Cameras: What License Plate Readers Know About You

Key Takeaway:
Flock Safety runs a network of more than 120,000 automated license plate reader (ALPR) cameras across the US. Each one photographs every passing car and logs the plate, the vehicle’s features, the location and the time into a database that police and other customers can search — often without a warrant, and sometimes across state lines. On 25 August 2026 a nationwide class action was filed claiming the system let officers stalk people and produced misreads that led to wrongful stops; none of those allegations has been proven in court. You can’t realistically avoid the cameras, but you can find out whether your town uses them and push for short retention and strict sharing rules.

What Is a Flock Camera?

A Flock camera is an automated license plate reader: a small camera, often solar-powered, usually on a pole at a road junction, a neighbourhood entrance or a shop car park. Unlike a traffic camera, it isn’t waiting for someone to break a rule. It photographs every vehicle that passes, reads the plate, and uploads a record to a searchable cloud database.

Flock sells to police departments, cities, homeowners’ associations and businesses. The customer decides where the cameras go and who can search the data — which is exactly why the rules, and the risks, vary so much from place to place.

📸 What the Cameras Record

Recorded	What that means in practice
License plate	Read automatically, including temporary and out-of-state plates.
Vehicle characteristics	Flock’s “Vehicle Fingerprint” lets users search by body type, make, colour and other features — so a car can be found without a readable plate.
Location	Which camera saw the car, and therefore where it was.
Date and time	When it passed — so a string of sightings becomes a route.
Faces	Cities using them, such as Campbell, California, say the cameras don’t capture people or faces.

A single photo of a car at a junction seems harmless. The privacy problem is what happens when thousands of them are stitched together. Enough sightings reveal where someone lives, works, worships, which clinic they visit and whose house they park outside overnight — a “pattern of life”, as the ACLU puts it. And nobody decided in advance that you were worth recording: everyone who drives past is in the database.

🔎 Who Can Search the Data?

Officially, the customer owns the data and controls access. A police department can keep its cameras to itself, or share with other agencies — and sharing is where most of the controversy lives.

Searches usually don’t need a warrant. In most places, an officer can look up a plate by entering a reason for the search. Warrantless use of Flock data has become a political issue ahead of the 2026 midterms.
Search reasons are easy to game. The ACLU documented officers typing reasons like “investigation” — or “hehehe” — to get past a required field, and says a later dropdown of approved purposes let officers pick any option, accurate or not.
Data can travel. A separate class action filed in California in February 2026 alleges that California plate data was shared with out-of-state and federal agencies, which California law restricts. The lawyers pointed to 1.6 million outside searches of the San Francisco Police Department’s database over seven months. Mountain View police ended their Flock contract after finding problems with how their data had been accessed.

Flock’s position is that customers set the rules, that it doesn’t sell data to third parties, and that it “takes privacy, legal compliance, and data security extremely seriously”.

⏳ How Long Is It Kept?

Flock’s default retention was previously 30 days, unless local law set a different limit. In August 2026, under growing scrutiny, Flock announced a shorter default of seven days, saying about 90% of searches already happen within a week. It also introduced an “Evidence Mode” for keeping records linked to active cases.

The ACLU says the default should be 48 hours, and warned that Evidence Mode could become a way to keep data indefinitely. Because the customer chooses the settings, the only way to know the retention period where you live is to ask your police department or city.

⚖️ The Nationwide Class Action

The case is Schulte v. Flock Group Inc., filed in federal court in Georgia on 25 August 2026 by Georgia resident Grace Schulte. As reported, the complaint alleges that:

Flock knew its system could be abused but didn’t adequately safeguard it, allowing current and former officers to use it to track people for personal reasons, including ex-partners.
Dozens of law enforcement officers around the country have been accused of misusing plate reader systems, many involving Flock.
Officers who had been fired could still log in with just a username and password.
The cameras produce inaccurate reads that have led to innocent drivers being wrongly stopped.

The proposed class is everyone in the United States whose license plate was scanned by a Flock camera since 1 January 2024, and it seeks damages for invasion of privacy. It is at the very start: a judge has not certified the class, and none of the allegations has been proven in court. If you’re wondering whether you need to do anything — you don’t, for now. If a class is certified, notices explain how to take part.

In response to the criticism, Flock has made multi-factor authentication mandatory for users, added alerts to supervisors for questionable searches, made case numbers required for searches and made its audit tool standard.

Can You Avoid Flock Cameras?

Honestly, not in any practical way. The cameras are on public roads and commercial property, and obscuring or altering a license plate is illegal in most states — and Vehicle Fingerprint searches don’t depend on the plate anyway. The useful levers are local and democratic, because the contracts are:

Find out whether your town uses them. Search your city or police department’s website for “Flock” or “ALPR”. Many publish a policy page, and some agencies publish a transparency page listing camera counts, retention and which agencies they share with.
Ask the specific questions. How long is data kept? Which outside agencies can search it? Is Evidence Mode used, and who approves it? Are searches audited, and are the audits public?
Use public records requests. Search logs and sharing lists are often obtainable, and much of what’s now known about misuse came from exactly these requests.
Show up when the contract is renewed. Camera contracts usually go through city councils, and some cities have ended or narrowed them — Mountain View cancelled its contract, and San Jose added limits on camera locations and retention.

License plate readers are one piece of a bigger picture. Your car’s route, your phone’s location, your IP address and the smart devices in your home each tell a partial story — and each can be requested by police in different ways. See how police can track you through your IP address and what smart home devices actually track.

FAQ

Do Flock cameras record faces?

Cities using Flock’s plate readers, such as Campbell, California, say the cameras capture license plates and vehicle characteristics, not people or faces. They do record your car’s plate, look, location and time every time you pass.

Can police search Flock data without a warrant?

In most places, yes — officers typically enter a reason for the search rather than getting a warrant. Local policies and state laws can add limits, which is why the rules differ between cities.

How long does Flock keep my plate data?

The default used to be 30 days. Flock announced a seven-day default in August 2026, but each customer sets its own retention within local law, and records tied to cases can be kept longer.

Am I part of the Flock class action?

The proposed class covers everyone in the US whose plate was scanned by a Flock camera since 1 January 2024, but a judge hasn’t certified it yet. There’s nothing to sign up for right now.

Is it legal to cover my license plate to avoid the cameras?

In most states, no — plates must be clearly visible, and covers that block cameras are commonly banned. It also wouldn’t stop searches by vehicle features. Local policy pressure is the effective route.

The Short Version

Flock cameras turn ordinary driving into a searchable location history for everyone, not just suspects. How much that matters depends on local choices — retention, sharing and auditing — that most residents never hear about. The class action may change how Flock operates, but the quickest way to change what happens to your data is still your own city council.
