Lens Canary

Somebody's glasses are also a camera.
Lens Canary gives you the heads-up.
A pocket detector that buzzes the moment Meta or Snap glasses come near. No phone or app required.
What it is
A little box that lives in your pocket.
About the size of a matchbox and battery-powered — drop it in a pocket or bag and forget it's there. When glasses come near, it buzzes and it lights up. No screen to check, no phone to pull out.
- Pocket-sized · battery-powered
- Subtle buzz to alert you
- Simple light showing when they are nearby
Not actual product
7,000,000
pairs of camera glasses sold in 2025 — more than triple the year before. They are silent by design. Lens Canary breaks the silence.
Start to finish
01
It hears them.
Camera glasses shout a maker's ID over Bluetooth they can't turn off. Lens Canary reads it over the air.
02
It buzzes you.
A buzz and a blink the instant one's in range. Peace of mind knowing you have the ability to detect them.
03
It stays quiet.
Sends nothing, saves nothing, needs no account. Open source, so you can check every word of that.
● What it can't do
It spots the glasses but there are limitations.
- It knows a pair is present — not whether they are recording.
- Gear made by the same company can trigger it too, for example, a powered-on Meta Quest VR headset.
No privacy tool should oversell. This one won't.
Peace of mind. In your pocket.
