Hidden camera detectors work by detecting the radio frequency signals that are emitted by the camera’s wireless transmitter. These detectors typically have an antenna that can pick up these signals and alert the user to the presence of a hidden camera. Some detectors also use infrared light to detect the lens of a camera, which will reflect the light back and reveal the location of the camera.
In addition to detecting hidden cameras, some detectors can also detect other surveillance devices, such as audio bugs or GPS trackers. These detectors work by picking up on the radio frequencies or other signals that these devices emit. By using a hidden camera detector, individuals can protect their privacy and ensure that their personal space is not being monitored without their consent.
