How Flock cameras work
Also known as: What are Flock cameras, What is a Flock camera, Flock camera system
A plain-language explanation of what a Flock camera is, what it captures, who can search the data, and how long records are kept.
What a Flock camera is
A Flock camera is a solar-powered, cellular-connected automated license plate reader built by Flock Safety. Physically it is a small dark box roughly the size of a shoebox mounted on a slim pole, usually with a solar panel on top and no visible wiring. It is motion-triggered and photographs the rear of every vehicle that passes, day or night, using infrared illumination.
What it captures and does with it
Software converts each image into a structured record: the license plate characters, state, vehicle make, body type, color, distinguishing features such as roof racks or bumper stickers, plus GPS coordinates and a timestamp. That record uploads to Flock OS, a cloud database. Flock says it does not use facial recognition, but the "vehicle fingerprint" can identify a specific car even with an obscured plate.
Who can search it
Agencies that subscribe can search their own cameras and, through network sharing settings, cameras owned by other agencies, cities, HOAs, and businesses. That means a camera installed by a neighborhood association can answer a query from a department hundreds of miles away. Audit logs record searches, and those logs are often obtainable through public records requests.
How long the data lasts
Flock’s default retention is 30 days, after which reads are deleted unless flagged, exported into a case, or covered by a longer local policy. Retention, sharing, and hot list rules are set per contract, which is why reading your city’s actual agreement matters more than the vendor’s marketing page.
FAQ
A small matte-black box on a narrow pole, typically 8–12 feet up, with a solar panel above it and a battery housing below. Many carry a small Flock Safety sticker or a city permit tag.
Standard Flock ALPRs are not speed enforcement cameras and do not issue citations. They log plate reads. Some newer Flock products advertise speed estimation, but ticketing requires separate certified equipment and state authority.
They capture still images triggered by passing vehicles rather than continuous video. Flock also sells separate live-video products that some agencies deploy alongside plate readers.
Photographing plates on a public road is generally legal in the United States, and courts have mostly upheld it. The active legal fights are about long-term retention, warrantless searching of aggregated location history, and interagency sharing.
