Glasses Radar turns your phone into a pocket sensor for camera-enabled smart glasses nearby — Meta Ray-Ban, Snap Spectacles and more. No account, no guesswork. Just a clear signal when smart glasses are close enough to matter.

What it detects
Known devices in the registry
Detection is based on Bluetooth fingerprints — manufacturer IDs, byte patterns, and service signals broadcast by the hardware itself. The registry grows as new hardware is reverse-engineered and verified.

Why this exists
A camera you can't see is still a camera.
Smart glasses look like ordinary eyewear and record with a light that's easy to miss — or tape over. That gap between "looks harmless" and "is recording" is already being exploited.
NO VISIBLE CAMERA
The only clue is a light you're not meant to notice.
Camera glasses are designed to disappear into a normal face. The recording indicator is a single small LED — one that's trivially covered with tape, easy to miss across a room, and never announces the person wearing it. Nobody nearby has any reliable way to know they're on camera. That's not a bug in the design. It's the whole appeal.

You're on camera now. This is the view no one consents to. What's below isn't hypothetical — it's already been reported.
01
Built for stalking, sold as a feature
In 2024, a pair of Harvard students paired Meta's smart glasses with facial-recognition software to identify strangers on the street in real time — pulling names, addresses and family details from a face alone, live, without the person ever knowing. It made headlines precisely because nothing about the glasses stopped it.
02
Non-consensual content, one click from a forum
Tech reporters have documented communities that exist to share candid photos and video of women in public, captured on smart glasses without their knowledge — the same "looks like normal glasses" design that makes them convenient is what makes covert recording effortless.
03
Institutions are already banning them
Gyms, bars, casinos and schools have started restricting camera glasses on premises — not because the tech is illegal, but because there's currently no reliable way for a bystander to know if they're being filmed. A ban only works if it's enforceable.
CapturedOne frame. One moment. No one asked.

RepostedScreenshotted, reshared — already out of reach.

RecirculatedNo name attached, no way to trace it, no single takedown that reaches every copy.
This isn't a hypothetical pipeline — it's the documented path from a covert recording to a stranger's screen. Awareness at the first step is the only point where anyone gets a choice.
Glasses Radar doesn't stop anyone from wearing smart glasses — it just gives the people around them the one thing they don't currently have: a way to know. Consent starts with awareness.
How it works
Radar, not guesswork.
Under the hood, Glasses Radar listens to the same Bluetooth and Wi-Fi signals every device broadcasts — and matches them against a growing fingerprint database of known camera-glasses hardware.
01
Scan
Passively listens for BLE advertisements and Wi-Fi signals in range — the same broadcasts every nearby phone, headphone and wearable already sends.
02
Match
Compares device signatures against a verified fingerprint registry — Meta Ray-Ban, Snap Spectacles and more — filtering out lookalikes like Quest headsets or earbuds.
03
Alert
Confirms the sighting is persistent (not a stray packet), estimates proximity, and notifies you the moment it's confident — near real-time, on-device.

On-device alert, near real-time
Your data
Zero collection. Zero compromise.
Runs entirely on-device
Detection, matching, and alerting all happen on your phone. No scan data, no locations, no device logs leave the device — ever.
No account, no sign-up
Open the app and it works. No email, no profile, no identifier tied to you. We have no way to know who you are — by design.
One-way database updates
The only server interaction is downloading fingerprint updates — a read, not a write. Your phone never sends anything back.
Free, always
Privacy tools should not be paywalled. Glasses Radar is free to download and use, for everyone, with no ads and no data monetisation.
