Camera detector
Camera detector for whatever room you're in.
Point, pan, and check what holds. The same sweep works on hotel rooms, rentals, offices and changing rooms, with nothing but the phone in your hand.

A detector is only useful if it's with you
The best camera detector is the one in your pocket when you need it, not the one that arrived in a padded envelope and lives in a drawer at home. That is the whole argument for doing this in a browser. There is no charging, no pairing, no firmware, and nothing to remember to pack. Open the page in the room, and the sweep is the same one you'd run anywhere else.
Signals
What a scan looks for
Three signals, all of them visible to a phone camera you already own.
Optical
Lens retroreflection
A camera lens sends light straight back where it came from. Sweep a bright light across a shelf and a hidden lens answers with a small, fixed glint that follows you.
Infrared
Emitter bloom
Night-vision cameras light the room with infrared your eyes can't see. Your phone's sensor can. It reads as a pale violet glow ringing the lens.
Placement
Sightlines
A camera has to see something to be worth hiding. The scan weights objects with a clear view of the bed, the shower door, and where you undress.
Sequence
How the scan runs
Four passes, in order. The last one is the scan's own work, not yours.
- 01
Allow the camera
The scan runs in the browser. Your phone asks once, and you can revoke it just as fast.
- 02
Sweep the room slowly
Hold the phone at chest height and pan one wall at a time. Slow beats thorough — a fast sweep skips glints entirely.
- 03
Check what it flags
Flagged points hold on screen with how long they have stayed put. Most of them will be screws, smoke sensors, or ordinary reflections.
- 04
Let it rule things out
As you move, the scan compares every flagged point against the room's own motion. A lens stays stuck to its object; a reflection slides off and gets marked as ruled out.
The rooms this gets used in most
Hotel rooms and short-term rentals, then changing rooms, then offices and meeting rooms where a camera is often entirely legitimate and simply undisclosed. The sweep does not change between them; what changes is where the sightlines are. In a bedroom the interesting wall faces the bed. In a changing room it is the mirror and the ceiling. In an office it is whatever faces the whiteboard and the screen.
Field guide
Where cameras usually are
Hidden cameras are placed for sightlines, not for cleverness. Start with anything that faces a bed, a door, or a shower.
Hotel room
- Smoke detectors mounted above the bed
- Alarm clocks turned toward the pillow
- TV bezels and set-top boxes
- Air vents on the bathroom wall
Short-term rental
- Shelf décor with a clean line to the bed
- USB chargers and power strips
- Routers placed unusually high
- Picture frames and wall art
Changing room
- Gaps in mirror seams and trim
- Coat hooks and hanger rails
- Ceiling tiles directly overhead
- Ventilation grilles at eye level
Privacy
Nothing leaves your phone.
The scan runs entirely in your browser. Frames from your camera are read, measured, and discarded in the same moment. They are never uploaded, never stored, and never sent anywhere. There is no account, so there is nothing for anyone to request from us.
