NoPeek: Hidden Camera Detect

Checking into a hotel or a rental and want peace of mind? NoPeek helps you search a room for hidden cameras, using methods that actually work rather than a needle that wobbles for show.

THREE WAYS TO SEARCH

Wi-Fi check
Lists every device on the network you are on, and identifies which ones are cameras — not by guessing from a port number, but by speaking the protocols cameras use and reading what they say about themselves. A device streaming video, or announcing itself as a camera, is reported as one. A router is reported as a router.

Nearby broadcasts
Some cameras record to a memory card or use their own SIM, so they never join your Wi-Fi and no network scan can see them. Many of those still broadcast a setup network or a Bluetooth signal. NoPeek listens for those too, and checks the hardware address against a list of camera manufacturers — a network name can be anything the owner typed, but the hardware address cannot be edited.

Lens finder
A camera lens reflects light straight back the way it came, so under a bright torch in a dark room it answers with a small sharp point of light. NoPeek turns on the torch, darkens the exposure so the glint stands out, and marks bright spots on screen as you sweep. It also blinks the torch to tell a true reflection from something that simply glows, and it names what it is looking at — a smoke alarm, a clock, a charger — so you know whether a reflection there is normal or worth a second look. Night mode switches to the front camera, which on most phones can see the invisible infrared lamps a night-vision camera uses.

ALSO INCLUDED

• Speaks what it finds, so you can keep looking at the room instead of the screen
• Walk to find it — follow a signal as you move and NoPeek tells you whether you are getting closer, turning "there is a camera" into "it is behind that mirror"
• Night watch — leave it running while you sleep and it tells you in the morning if anything new joined the network
• Compare with your last check, so a device that was not there before stands out
• Save a photo of anything you find, with the time and place, in case you need to show someone
• Magnetic check with a baseline you set yourself, showing real change rather than a made-up reading
• Step-by-step room guide covering the places cameras are actually hidden: smoke alarms, vents, chargers, clocks, picture frames, and the fingernail test for two-way mirrors
• Twelve languages, following your phone or chosen in the app

HONEST ABOUT LIMITS

No phone app can promise to find every hidden camera, and any app that says otherwise is selling you something. A camera that records to a memory card, hides behind a pinhole, or is switched off may not show up. NoPeek tells you what it found, how it knows, and what it cannot see — including when the network you are on hides devices from each other, which is common in hotels and would otherwise look like a clean result.

YOUR PRIVACY

NoPeek has no server and no account. Nothing you scan leaves your phone. There is no analytics and no advertising. Android requires location permission before any app may list Wi-Fi network names, so NoPeek asks for it — and uses it for nothing else. Your position is never read, stored or sent.

FREE AND PAID

The Wi-Fi check is free and always will be. A single payment unlocks the full device list, manufacturer identification, and the lens and night tools. No subscription, no adverts.
