Cam Finder

With Cam Finder, you can detect hidden cameras and devices in Airbnb homes or hotels you visit for vacation or business.

Cam Finder uses your phone's magnetic field sensor to calculate the stable magnetic field of your surroundings. When you bring it close to surfaces without electronic devices (places where there is no element that can emit a magnetic field, such as mirrors, etc.), you will receive a high magnetic field alert. You can then use the high-contrast camera in the Cam Finder app to view the area with the high magnetic field alert. Lenses from cameras and other devices will then be reflected in your high-contrast camera.

Cam Finder does not store any data and operates in real-time.
