KAIST's $7 LED Attachment Turns Smartphones into Hidden Camera Detectors
Smartphone LED detects hidden cameras with AI
Researchers at KAIST, with collaborators from NUS and SMU, have developed SweepLED, a smartphone-based hidden camera detector using a cheap LED attachment and AI. The system analyzes reflection patterns from camera lenses, distinguishing them from ordinary glossy surfaces, achieving 94% accuracy in under five seconds. The hardware costs about $7, promising an affordable consumer accessory to combat illegal cameras in hotels and restrooms.
By combining low-cost hardware with AI analysis, we have demonstrated the potential for a detection technology that even non-experts can use easily.

Until someone develops hidden cameras with AI that will be auto turned on couple of hours later after detecting presence at that time a scan was already performed and nothing was found.....

If this worked with IR, and so non visible, it might be even more useful.
Great idea though.

I wonder if it works with smart glasses.

Cool, but we need that for microphones.

Yeah I don’t think this will be effective, cameras can be put in certain angles that it can see with being seen, or how police do it, entirely behind clothes or similar fabric where it can see through and identify but not seen even if you’re looking straight at it.
