Hidden Camera app uses your devices magnetic sensor to detect hidden cameras everywhere and makes your phone like a real Hidden Cameras detector.
App works best detecting metal cameras up to 15cm away, and working best detecting ferromagnetic materials, such as camera and can’t detect non-ferromagnetic materials such as aluminum.
The magnetic field of the cameras in nature ranges from 25 to 65 µT (0.25 to 0.65 G). Data is displayed in µT (micro Testla). 1µT = 10mG (milli Gauss). Any higher calculation is an indication of metal in the area. When there is metal in the area, magnetic field increases.
Hidden Camera detecting is simple to use, just open it and move it around the suspected objects . If the magnetic field values rise then there is a hidden camera or microphones in the area. Accuracy of the app is entirely dependent on the magnetic sensor in your device and is affected by electrical equipment such as TVs, PCs… due to electromagnetic waves.
Note : If the app does not work as it should then the problem is in your magnetic sensor of your device. Maybe your device does not have one. Or try to initialize the sensors by pointing your phone up and rotate it in a figure 8 pattern.
