A Flock camera is an automated license-plate reader (ALPR) made by Flock Safety. Below are the basics, each with a source. For deeper dives, see our Flock camera FAQ, how to spot one, and the court cases.

What it does

It photographs passing vehicles and reads their plates. Agencies load hot lists, such as stolen cars and wanted plates, and get alerts on a match. Stoughton, MA police call a hit "only a lead" that needs more investigation (Stoughton PD). It is "NOT used for traffic enforcement," per a Flock presentation (Contra Costa County packet).

What it captures

Still images, plus what Flock calls Vehicle Fingerprint: make, body type, color, plate state and type, missing plates, and "other identifiers (roof rack, window stickers, toolbox, and more)" (Tukwila, WA FAQ). That lets users search for a car without its plate number (EFF).

What it looks like

Flock's spec sheet lists the plate camera at 8.75 × 5 × 2.875 inches and 3 lbs, mounted with adjustable band clamps, uploading "via integrated LTE," with solar panels for poles (Long Grove, IL document). USA Today says they're typically on a black pole with a camera on one side and a solar panel on the other, along highways, near intersections or on busy roads, and that some Flock models look more like regular security cameras (USA Today). Our spotting guide has more.

How many there are

Flock doesn't publish locations. In our OpenStreetMap snapshot of 2026-10-14, volunteers had reported 144,361 license-plate readers in the US, 115,116 of them tagged Flock Safety. Every one is reported, not verified. See the ones near you or open the Flock camera map.

How long data is kept

Flock says its default was 30 days unless state or local policy says otherwise, and it now recommends 7 days for new setups. Some states set limits by law (ALPR laws by state).

Are Flock cameras legal?

Generally yes, but state rules differ. In January 2026 a federal court granted Norfolk, VA summary judgment in a Fourth Amendment challenge to its Flock cameras (order), and the plaintiffs appealed. On Oct. 1, 2026, a federal judge in Oklahoma held that one deputy's warrantless search of a month of a driver's Flock history was unconstitutional (U.S. v. Kyle). That ruling binds only that case, and most courts have ruled the other way (The Ruling Desk). See all the cases and your state's law.
