Spotting Hidden Cameras: Practical Techniques and Their Limits
Hackaday collects practical methods for detecting hidden cameras in rooms, noting that standard RF detectors can miss wired or unusual-camera setups, while optical tricks like shining light (or using a smartphone camera to spot retroreflective lenses), IR scans, and even thermal imaging can reveal cameras—even when they’re off. The BBC case shows how tiny devices can be hidden behind everyday objects, but no single method is foolproof, and readers are invited to propose new approaches.
