Why This Guide Exists
Automated license plate readers now log where tens of millions of ordinary cars go, every day, and share those logs across agencies you have never heard of. The largest operator, Flock Safety, has no consumer opt-out. This guide covers what these cameras are, how to spot and map them, what happens to the data, and the limited but real levers you actually have.
What Flock and ALPRs Actually Are
An automated license plate reader (ALPR) is a camera that photographs every passing plate, converts it to text, and records the plate, location, and timestamp in a searchable database. Flock Safety's own product page describes its cameras as solar-powered, LTE-connected units that install in hours with no wiring, capturing a vehicle's make, model, color, a "Vehicle Signature," the plate, location, and time. Flock states the cameras do not use facial recognition or collect information tied to individuals.
The reach comes from the network. Local agencies build custom "hot lists," and Flock also lets them compare plates against FBI NCIC categories, including an "Immigration Violator" category populated exclusively by ICE. A match triggers an automatic alert, and because agencies share hot lists, a scan logged by one town's camera can surface to any other agency on that list. The Electronic Frontier Foundation documented this cross-agency alerting in June 2026.
Scale figures vary by source and date, and no single authoritative live count exists. EFF estimated 80,000 to 100,000 Flock cameras deployed as of early 2026. The ACLU notes that roughly one in ten reads misidentifies the plate's issuing state, and that under 1% of ALPR scans connect to an actual crime.
How to Spot a Flock Camera
Once you know the shape, they are hard to unsee. According to a teardown by CEHRP, a typical Flock unit is a small black rectangular box, roughly nine inches long, mounted eight to twelve feet up on an existing utility or light pole (or a dedicated Flock pole), paired with a small black solar panel and no visible wiring, since both power and data are wireless. They are commonly placed at intersections and highway on- and off-ramps, angled at a traffic lane, and use infrared LEDs with motion-triggered capture rather than continuous recording.
Map Them With DeFlock
The community project DeFlock (deflock.org, which the older deflock.me redirects to) crowdsources ALPR camera locations onto OpenStreetMap. Volunteers photograph cameras and add tagged map points, and the map renders live from OpenStreetMap data. As characterized by mapatlas.eu, the underlying OpenStreetMap dataset held roughly 336,000 ALPR-tagged points worldwide in 2026 (spanning Flock and other vendors), making it the largest crowdsourced ALPR registry available. The project runs with no login required to browse, and states it uses no tracking, analytics, or ads. Checking DeFlock for your area is the fastest way to see which routes are already covered.
The Data Rules, and Why There's No Real Opt-Out
Here is the hard truth: there is no national opt-out registry for ALPR data, and no consumer-facing way to remove yourself from Flock. Flock positions itself as a data processor, not the data owner. When a California resident invoked their CCPA rights in April 2026 and demanded deletion, Flock replied that the request "cannot be completed" and redirected them to the specific law-enforcement agency that owns the camera data.
Per Flock's stated policy, the default data retention is 30 days, after which footage is automatically deleted "unless local law says otherwise," extendable up to a year with an agency's approval. Flock frames data sharing as "a local choice" controlled by the contracting agency.
That leaves two real levers:
- Request records or deletion from the agency, not Flock. The police department operating a given camera is the data controller. In states with strong privacy law (California's CCPA, for example), a request to that agency may carry legal weight that a request to Flock does not.
- Route avoidance. Data can only be collected on a plate that passes a camera. Using DeFlock to understand where the cameras sit is the only practical way to reduce how often your movements are logged.
The 2026 Backlash
The system is under real pressure. A GovTech analysis counted 82 Flock contracts terminated across 28 states between August 2021 and May 2026, with 39 of those in the first five months of 2026 alone. A California class action alleges Flock shared ALPR data with out-of-state and federal agencies in violation of state law, citing SFPD data being searched from out of state more than 1.6 million times over seven months, per KTVU.
The throughline behind most cancellations is federal data access. In Dayton, Ohio, an audit found the city's Flock cameras had been searched more than 7,100 times for immigration-enforcement purposes in violation of city policy; the city suspended the data and physically covered the cameras with black trash bags. And a Yahoo News investigation documented officers using Flock to track ex-partners, and one Texas deputy searching more than 83,000 cameras for a woman suspected of a self-managed abortion, after which Flock added keyword filters blocking "abortion" and "immigration" as search reasons.
The Bottom Line
You cannot make yourself invisible to a system with no opt-out, but you are not powerless. Learn what the cameras look like, check DeFlock for your area, direct any records or deletion request to the agency that owns the camera rather than to Flock, and support local oversight where you live. The fastest-growing pushback against ALPRs in 2026 has come from residents at city-council meetings, not from a settings menu.
