The surveillance technology America's governments operate
Which agencies operate license-plate readers, cameras, face recognition, drones, and acoustic sensors, and where, with a citation behind every entry. State by state; the oversight around each system is the next layer of the record.
The observatories
One observatory per jurisdiction, each with its map, technology filters, and detailed local records.

The technologies in the United States
Counts are U.S. deployments on the public record, across every launched state. A zero means none on record, not necessarily none in operation.
ALPR
Automated license plate readers (ALPR): camera systems that automatically capture, read, and log vehicle license plates with location and time, producing a searchable record of vehicle movements.
4,095 on recordFixed cameras & RTCC
Agency-operated fixed video cameras and the real-time crime centers (RTCC) that aggregate live and recorded feeds for monitoring. Extends the Electronic Frontier Foundation's Atlas, which enumerates real-time crime centers and camera registries but not standalone fixed-camera estates.
323 on recordFace recognition
Software that matches faces in images or video against a reference database to identify or verify individuals.
978 on recordDrones / UAS
Uncrewed aerial systems (UAS), commonly called drones, operated by an agency for overhead observation, imaging, or sensing.
1,805 on recordGunshot detection
Networks of acoustic sensors that detect and locate suspected gunfire and alert an agency.
246 on recordBody-worn & dashcam
Officer body-worn and in-vehicle dashboard cameras that record encounters; public access to the footage is frequently restricted.
5,467 on recordDoorbell & camera registry
Programs that give an agency access to privately owned camera footage: doorbell-camera partnerships, citizen camera registries, and private-camera integration platforms.
756 on recordCell-site simulators
adjacentDevices that mimic cell towers to locate or identify nearby mobile phones. They are often called Stingrays, or IMSI catchers after the international mobile subscriber identity (IMSI) number that identifies each phone on a network. Adjacent: communications surveillance outside the visual/sensor core.
83 on recordPredictive policing
adjacentSoftware that forecasts where crime may occur or who may be involved, to direct policing. Adjacent: analytics rather than a sensing deployment.
200 on recordSocial-media monitoring
adjacentTools that collect and analyze public social-media activity for an agency. Adjacent: open-source/communications monitoring outside the visual/sensor core.
none on recordAbout this record
Deployment data is compiled from public sources, and each entry keeps the citations it came from. The oversight around each system (published policy, public-access path, disclosed data-sharing, legislative limits) is recorded separately, from public-records requests filed within each state's own law; see the United States records-law analysis. Until a jurisdiction's records arrive, its oversight status reads not yet requested. Full notes on the methodology page.
