What is a Flock camera?

A Flock camera is an automated license plate reader (ALPR) made by Flock Safety. It photographs every vehicle that passes, reads the plate, and records the plate number with the date, time and location — building a searchable history of where a vehicle has been seen. Most Flock cameras are also networked together, so a search doesn't stop at one camera: it can span every device an agency has deployed, or every device belonging to another agency in the same sharing network. Flock cameras are not triggered by a violation, and they do not issue tickets.

What is a Flock camera, exactly?

A Flock camera is an automated license plate reader (ALPR) made by Flock Safety. It is a small, solar-powered camera mounted on a pole beside a road that photographs every vehicle that passes, reads the license plate with software, and records the plate number along with the date, time and location. It also logs a "vehicle fingerprint" — color, body type, and features like roof racks, bumper stickers or damage — so a vehicle can be searched for even when the plate is unreadable. Flock cameras are typically bought by police departments, homeowners associations and private businesses.

What are Flock cameras?

Flock cameras are the individual automated license plate readers made by Flock Safety, but the plural term usually points to something bigger than one device: the network those cameras form together. A single Flock camera only sees traffic passing its own pole. Because many agencies that buy Flock cameras also opt into Flock Safety's shared search network, plate data captured by one department's cameras can become searchable by another department across town, county or state lines. So when people ask what Flock cameras are, in practice they are usually asking about that combined system — many cameras plus the shared search layer connecting them — not a single device.

What do Flock cameras record?

Flock cameras record a still image of each passing vehicle, the license plate number read from that image, the date and time, and the camera location. They also record a vehicle fingerprint describing color, body type and distinguishing features. Flock Safety states that its cameras do not record audio, do not use facial recognition, and are aimed to capture vehicles rather than people. The result is a searchable history of where a given vehicle has been seen.

What are Flock cameras used for?

Flock Safety markets Flock cameras for recovering stolen vehicles, supporting Amber Alerts and other missing-persons searches, and giving police an investigative lead — searching which vehicles passed a location without needing a witness to come forward. That stated purpose is not the whole picture that has been documented publicly. Journalists and civil-liberties groups have reported cases of Flock camera searches run for reasons unrelated to the original justification, camera data shared with agencies outside the jurisdiction that installed the cameras, and out-of-state or federal agencies — including, in some reported cases, immigration enforcement — gaining access through the sharing network described above. Critics call this pattern "mission creep": a surveillance system built for one purpose tends to expand into others once it exists. Whether a given Flock camera network stays limited to its stated purpose depends on the policies of whichever agency operates it, and those policies vary by department.

How long does Flock keep license plate data?

Flock Safety's default retention period is 30 days, after which data is deleted automatically. However, retention is configured by the agency that owns the cameras, and some jurisdictions set longer or shorter periods, while data copied into a case file or shared with another agency can persist well beyond the original window. Retention rules vary by state and by department policy.

Are Flock cameras legal?

Flock cameras are legal in most of the United States. Courts have generally held that a license plate on a public road carries no reasonable expectation of privacy, so photographing it is not a search. That consensus is being tested: some courts have found that long-term, networked ALPR tracking is different in kind from a single observation, and a number of states regulate ALPR data retention, sharing and permitted uses. Rules differ significantly by state.

Who can see Flock camera data?

The agency or organization that owns the cameras can search its own data, and Flock Safety operates a national sharing network that lets participating agencies search each other's camera data. That means a plate photographed in one town can be searchable by a department hundreds of miles away if both belong to the network. Homeowners associations and private businesses that install Flock cameras can also grant law enforcement access to their footage.

How can I find Flock cameras near me?

You can look them up on a public map. FlockScanner maps 138,636 ALPR camera locations across the United States, including Flock Safety cameras, drawn from OpenStreetMap where volunteers have documented them. You can browse the interactive map, search a state directory, or plan a driving route that avoids known camera locations. Coverage depends on what volunteers have mapped, so it is a lower bound rather than a complete list.

What is the difference between a Flock camera and a red-light camera?

A red-light or speed camera is triggered by a specific violation and exists to issue a citation for that event. A Flock camera is not triggered by a violation — it photographs every vehicle that passes, regardless of whether anything unlawful occurred, and builds a searchable record of vehicle movements. Flock cameras do not issue tickets; they create a database that can be searched later.
