Researchers from KAIST, formerly known as the Korea Advanced Institute of Science and Technology, who collaborated with the National University of Singapore (NUS) and Singapore Management University (SMU), have developed a clip-on LED light that works in tandem with an AI app to detect hidden cameras. According to The Chosun Daily, the team, led by Professor Han Jun of KAIST’s School of Computing, called the technology SweepLED [PDF], and it used an LED light grid that magnetically snaps to your power and an AI-powered app to analyze the image taken.
There are many ways to detect hidden cameras using your smartphone — this includes shining a flashlight around the room to spot tiny reflections coming from tiny lenses, using your phone’s camera to detect infrared emissions from hidden cameras, or using camera apps with reflection analysis. However, the first two methods require manual scanning, meaning you’re likely to miss something small and unnoticeable, while the last method is prone to false positives. Because of this, the research team decided to make their own solution using artificial intelligence.
