Researchers Build $7 Hidden Camera Detector for Phones

TechRadar reported that a phone accessory called SweepLED can spot hidden cameras in 5 seconds. The prototype uses LED reflections and could cost only $7. Tom's Hardware described how Korean researchers built a $7 smartphone clip-on that spots hidden cameras. It relies on AI and a dynamic LED grid to separate reflections from lenses for 94% accuracy. Both outlets presented the development as a practical use of AI tools for consumer security.
