Hidden Camera Detector Sweep

Check a room in five minutes with the sensors your phone already has. Straight about what it can and cannot find.

Your phone already carries the sensors a hidden camera detector uses: a radio, a magnetometer and a camera. This app turns them into a five-minute sweep of any room — and tells you plainly what each check can and cannot find. It cannot prove a room is clean, and it does not claim to: a phone can only report what these five methods returned, and a camera that is offline, on another network, or well enough concealed will not appear in any of them.

FIVE CHECKS, EACH FINDING SOMETHING THE OTHERS CAN'T

Network scan — lists every device sharing the Wi-Fi you are on, and flags the ones answering on ports cameras use. Each device is shown with the reason it stood out, so you judge it rather than trusting a verdict.

Lens reflection — a lens sends light back along the path it arrived on. Under the torch it answers as a small, steady bright point that stays put while everything else shifts as you move.

Infrared viewer — night-vision cameras light a dark room with infrared your eyes can't see. The front camera can often see it as a pale violet dot.

Bluetooth scan — some cameras and trackers announce themselves over Bluetooth. Signal strength rises as you get closer.

Magnetic field — the magnetometer reacts to metal in a housing at very close range.

WHERE TO ACTUALLY LOOK

A room checklist walks you through the six places cameras genuinely turn up — smoke alarms, sockets and chargers, air vents, anything with a clock face, décor above eye level, and mirrors facing the bed or shower — with what gives each one away.

WHAT THIS APP WILL NOT DO

It will not tell you a room is clean. Every check here has limits and every screen says what its own are. The network scan cannot see a camera on another network, on mobile data, or recording to a card with no network at all. Bluetooth only finds devices actively broadcasting. The magnetometer reacts to any metal, so a screw reads the same as a camera. A sweep that finds nothing means these methods found nothing — no more than that.

Apps in this category that show you a green tick and call it safety are selling a feeling. This one is built to be useful instead.

PRIVATE BY CONSTRUCTION

Everything runs on your phone. Nothing is uploaded, no account is needed, and the infrared and lens checks only draw a preview on screen — no photo or video is recorded or saved.

FREE AND PREMIUM

Every check is free three times a day. Premium removes the daily limit, keeps your scan history so you can re-check a room later, and shows full device detail. You can also watch a short ad for one extra sweep instead.
