Count the plate readers in your area

Your search goes to a public Overpass server, and place names to OpenStreetMap’s Nominatim. Nothing goes to Max Intel. Counts are cameras volunteers have tagged surveillance:type=ALPR in OpenStreetMap, not an official register. Data © OpenStreetMap contributors, ODbL.

How many license plate readers are mapped in the US?

143,919 across the 50 states and DC on 21 October 2026, or 42.3 per 100,000 residents. That is up 27,264 (23%) from 116,655 on 17 July 2026. Every state rose. Pennsylvania nearly doubled, from 2,017 to 3,937, and New Jersey rose 64%.

The ten most-covered states per person, and the five least:

The full 51-row table, with population, CSV, JSON and the query, is in our ALPR cameras by state dataset. Our count fits outside figures: Jalopnik reported DeFlock mapping 143,356 US plate readers on 4 October Jalopnik (4 Oct 2026).

Is this every camera?

No. It is a floor. A camera enters OpenStreetMap only when a volunteer finds it and tags it. Busy, well-mapped places look denser than places nobody has surveyed.

No official list exists to check against. RoadSigns.com puts it plainly: “There is no complete public registry, so the exact number of active cameras cannot be confirmed.” RoadSigns.com (data as of 26 Aug 2026)

Contracts and cameras also move at different speeds. The Institute for Justice counts 277 local governments that cancelled or did not renew plate-reader contracts since January 2025 Institute for Justice (as of 16 Oct 2026). Yet every state’s mapped count rose between July and October, because cameras come off the map only after they are removed and a volunteer deletes them.

How does the counter work?

  1. You type a place. OpenStreetMap’s Nominatim search finds its boundary, with one request per click, as its policy requires Nominatim usage policy (read 21 Oct 2026).
  2. The counter asks a public Overpass server for every node tagged surveillance:type=ALPR inside that boundary. It downloads tags only, not locations, so even California is quick.
  3. It totals them, counts those tagged manufacturer=Flock Safety and lists the top manufacturers and operators. The OSM wiki gives manufacturer=Flock Safety as the correct tag and calls Flock “the largest vendor of ALPR devices in the United States” OSM Wiki: surveillance:type=ALPR (edited 6 Oct 2026, read 21 Oct 2026).
  4. For a state, it compares the result with our 21 October 2026 snapshot and the Census population.

“Every state” runs the one query behind our 21 October count and lets you download the table. Want the cameras themselves on a map? DeFlock’s map shows them street by street, and our OpenStreetMap Query Builder lists and exports them.

What can I do with the number?

  • At a council meeting. Compare your town’s rate with the state and national rate before a contract vote.
  • In a records request. Ask your police department for its camera list and audit logs, then check the count against it. Our mapping guide walks through it.
  • In reporting. Pair the count with what officials have said in our police statements dataset and the misuse cases.
  • To improve the map. If your town looks low, the cameras may simply be unmapped.

Frequently Asked Questions

How many Flock cameras are near me?

Type your town, city, county or ZIP code into the counter above and press Count cameras. It shows how many license plate readers volunteers have mapped there, how many are tagged as Flock Safety, and the rate per 100,000 people when a population figure is available.

How many license plate reader cameras are in the US?

We counted 143,919 plate readers of all brands tagged in OpenStreetMap across the 50 states and DC on 21 October 2026, or 42.3 per 100,000 residents. That is up from 116,655 on 17 July 2026. It is a count of mapped cameras, not an official register, and the real number is likely higher.

Which state has the most license plate readers?

California has the most mapped, with 21,454 on 21 October 2026. Per person, Georgia leads with 91.2 per 100,000 residents, followed by Kansas at 70.6. The national rate is 42.3.

Where does the counter get its numbers?

From OpenStreetMap, the free map anyone can edit. Volunteers, many working with the DeFlock project, tag plate readers with surveillance:type=ALPR and often manufacturer=Flock Safety. The counter asks a public Overpass server how many of those tags fall inside your area.

Why is the count for my town zero or low?

Usually because nobody has mapped the cameras yet. A camera appears only after a volunteer spots it and adds it to OpenStreetMap. A low count can also mean the place has no boundary in OpenStreetMap, in which case the counter searches within 5 km of its centre.

Does Max Intel see what I search?

No. Place names go to OpenStreetMap Nominatim and the count request goes to a public Overpass server, straight from your browser. Nothing is sent to Max Intel, and the page does not use your location.
