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 is building a worldwide record, so far covering the United States, the United Kingdom, Ireland, and Australia, with a citation behind every entry.

14,024 deployments on record 9,033 agencies 4 countries so far 9 technologies on record

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, expanding worldwide. Covered so far: the United States, the United Kingdom, Ireland, and Australia. Deployments on the public record, mapped by local jurisdiction and technology.

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

Every entry keeps its citations, and the oversight layer is built from each jurisdiction's own public-records law. Full sourcing and methodology, including what this data is and is not, are on the methodology page.
