The search directly on osm.org is optimzied for address things.

For a "complete" search in the OpenStreetMap-data I suggest [Overpass Turbo](https://wiki.openstreetmap.org/wiki/Overpass_turbo).

In this specific case I'd take a little detour over taginfo (https://wiki.openstreetmap.org/wiki/Taginfo), e.g. search for `surveillance` (https://taginfo.openstreetmap.org/search?q=surveillance) there. A little bit of clicking (Type > Values > ALPR) leads to https://taginfo.openstreetmap.org/tags/surveillance%3Atype=A... If you click on 'Overpass turbo' on the top right, you get to a pre-filled search on Overpass turbo. Scroll the map to the region you want to search (start small), and click 'Run' on the top left.

Voila.

Fantastic! Thank you :)

However, even ALPR doesn't show any devices for me:

I'm glad citizens in the EU are more on top of this. I really wish we as USA citizens had access to the same database of GPS coordinates for each Blink, Ring, and Amazon Key device that police do. Does anyone know how/if something like that could be FOIA'd? This seems it would be particularly fruitful if FBI/DHS has a comprehensive dataset for the entire nation.

Though I do worry that they may not "have" the dataset, but rather just have "access" to it via a queryable Amazon/Palantir database/API.

I've panned the map over several parts of the US, and see many ALPRs mapped in OpenStreetMap. You can also use the 'Wizard' of Overpass turbo, and enter ""surveillance:type"=ALPR around Miami" (or any other city (e.g. your home town), with quotation marks around surveillance:type) and increase the `radius` in the query until you'll find some. As an example, here are the ALPRs 25km around Miami: https://overpass-turbo.eu/s/2dVP
