Argus – Hidden Camera Detector
Four ways to check a room for hidden cameras, in one iPhone app.
Argus combines four scans in one app: a Wi-Fi scanner, a Bluetooth scanner, an infrared and lens-reflection camera finder, and a magnetometer scanner, so you are not relying on a single sensor. Use it in a hotel room, an Airbnb or a rental car. It works on any iPhone running iOS 16 or later.
Every scan runs on your iPhone and is never uploaded. There is no account to create and no ads. The Camera Finder is free to use in full; Argus Pro, an optional weekly or yearly subscription, shows which device is which and unlocks the Magnet Scanner.
No app can find every hidden camera, and Argus says so plainly: a clean result is a reason to keep looking, not proof that a room is clean.
