Detect Hidden Cameras

Source: https://static.makeuseof.com

Through the use of the Hidden Camera Detector app, your Android smartphone’s magnetic sensor can detect hidden surveillance cameras. Upon selecting the magnetometer scanning method, an alert will be made if there’s a fluctuation in the magnetometer reading when you move the phone closer to the direction of suspected hidden cameras. However, if your device does not have a magnetic sensor, you will have to rely on the detect infrared camera mode to find cameras in the location.
