The surveillance technology governments operate
WatchWatch documents the surveillance technology governments operate, from license-plate readers and cameras to face recognition, drones, and acoustic sensors. It covers the United States, the United Kingdom, and Ireland, with a citation behind every entry.

An observatory, not a campaign: WatchWatch records what exists and its status; readers draw their own conclusions. About this site →
The observatories
One observatory per country. Deployments on the public record, mapped by local jurisdiction and technology. Every shaded state links to its own observatory.
Explore the United States: 13,932 deployments · 8,960 agencies · 56 states and territories →
The record also covers Puerto Rico · U.S. Virgin Islands · Guam · American Samoa · Northern Mariana Islands.

The technologies
The categories the observatory tracks, counted across every covered jurisdiction. A zero means none on record, not necessarily none in operation. New to the subject? The technologies page explains each in plain language.

The oversight layer
The record currently documents deployments: that a system is in operation, per public sources. It does not yet record the oversight around each system — whether the agency has published a use policy, whether the public has a path to the footage or data, what data-sharing is disclosed, and what legislation governs the technology.
Those records come from public-records requests, filed within each jurisdiction's law. Until a jurisdiction's records arrive, its oversight status reads not yet requested — a status, not a verdict.
How this record is built
United States deployment data comes from the EFF Atlas of Surveillance (CC BY 4.0), a public dataset compiled by the Electronic Frontier Foundation and the University of Nevada, Reno, credited on every page that renders it. The United Kingdom and Ireland records are compiled from force-, Garda-, and government-published records. Each entry keeps its citations, and the oversight layer is built from each jurisdiction's own public-records law (United States · United Kingdom · Ireland). The full notes, including what this data is and is not, are on the methodology page.
