This is a handheld radio-frequency detector that sweeps for hidden cameras, GPS trackers, listening bugs and wireless monitors. It works by picking up the radio signals those devices emit and alerting you with sound, light or vibration as you move it around a room. It suits travelers, renters and anyone worried about surveillance in a hotel, office or short-term rental. Compared with phone-based detector apps, a dedicated unit like this senses a wider band of transmissions, but it cannot see wired or fully offline cameras and it will react to ordinary Wi-Fi and Bluetooth traffic.
