watching you.
458,500+ surveillance records aggregated from FLOCK (Ringmast4r), EFF Atlas of Surveillance, OpenStreetMap, DeFlock, government open data, and 20+ other public sources, across 183 countries. CCTV, ALPR readers, facial recognition systems, speed cameras, ShotSpotter sensors. Search any address. See what is watching.
What Sentinel Shows You
Aggregated from public records, community mapping, and open databases. Updated regularly. Never user-contributed location data.
CCTV Cameras
Hundreds of thousands of fixed surveillance camera records aggregated across 183 countries from FLOCK + EFF + OSM + Gov + Community sources. Fixed, dome, and pan-tilt-zoom installations in public and private spaces. Specific CCTV sub-count varies as ingest refreshes; see the map for live filter totals.
ALPR Readers
Thousands of automatic license plate readers across North America and Europe, drawn from FLOCK community contributions and government open-data feeds. Flock Safety, police-operated, and toll cameras that log every vehicle. Live ALPR sub-count visible in the map's filter panel.
Facial Recognition
Cameras connected to facial-recognition systems. Vendors like Clearview AI have publicly disclosed billions of indexed faces sourced from public web scraping (per congressional testimony and FTC filings); the exact deployment footprint per jurisdiction is what Sentinel surfaces from open records.
Gunshot Detection
ShotSpotter/SoundThinking microphone arrays. Deployed across ~150 US cities per the vendor's own disclosures; civil-liberties groups have documented audio capture beyond gunshot events. Per-site deployment data is what Sentinel maps from public-records sources.
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.
Why mapping the watchers is not surveillance.
A database of surveillance assets is itself a surveillance asset. A hostile actor could read Sentinel as a map of where to plan operations around blind spots. We treat that question directly rather than wait for a reviewer to surface it.
Three structural answers. First, every record in Sentinel is already public. The underlying data lives on FLOCK (Ringmast4r), EFF Atlas of Surveillance, OpenStreetMap, DeFlock, and government open-data feeds. Symvek does not collect data. Symvek integrates what is already published, normalizes the schema, and makes it searchable. Removing Sentinel does not remove the data; it only removes the integrated search experience.
Second, the asymmetry that drives mass-surveillance harm runs in one direction. Citizens cannot audit the cameras pointed at them; agencies do not publish their installations; vendors do not publish their integration agreements. The information advantage already sits with the watchers. A search tool that lets a journalist, an oversight board, a defence lawyer, or a citizen verify what is observing them in their neighbourhood narrows that asymmetry. It does not widen it.
Third, the dual-use posture is explicit and not deniable. Symvek will not provide custom enrichment, real-time alerting on agency installations, or any service that would meaningfully advantage a hostile actor over a citizen, journalist, or oversight body. The product is the same map for everyone, sourced from public records, run client-side. We answer the dual-use question with the architecture, not with a policy.
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.
