What Sentinel shows you
Aggregated from public records, community mapping, and open databases. Updated regularly. Never user-contributed location data.
CCTV Cameras
351,000+ surveillance cameras mapped across 101 countries. Fixed, dome, and pan-tilt-zoom installations in public and private spaces.
ALPR Readers
9,400+ automatic license plate readers across North America and Europe. Flock Safety, police-operated, and toll cameras that log every vehicle.
Facial Recognition
Cameras connected to facial recognition systems. Clearview AI serves 3,000+ law enforcement agencies with 70 billion indexed faces.
Gunshot Detection
ShotSpotter/SoundThinking microphones. 25,000+ always-listening devices in ~150 US cities. Can capture conversations.
Drones
Law enforcement drone programs tracked by jurisdiction. Increasingly deployed for routine patrol, not just incident response.
Body Cameras
Police body-worn camera programs. While intended for accountability, they also capture everyone in the officer's field of view.
How it works
Public data only
We aggregate data from EFF Atlas of Surveillance, OpenStreetMap, and community mapping projects. All public records. Nothing proprietary.
Runs in your browser
The entire map runs client-side. Your searches, your location, your browsing -- nothing leaves your device. We never know where you looked.
No tracking, ever
No analytics. No cookies. No telemetry. No user accounts. We map the watchers. We never watch you.
Data sources
Transparent about where every data point comes from.

The cameras don't go away.
But now you can see them.
Surveillance infrastructure works because it's invisible. Sentinel makes it visible.
