    "prose": "Researchers at KAIST developed a new tool called SweepLED that detects hidden cameras in under five seconds with approximately 94% accuracy. [^1]\n\nResearchers from the Korea Advanced Institute of Science and Technology (KAIST) developed SweepLED, a portable phone accessory designed to detect hidden surveillance cameras. [^2]\n\nSweepLED works by moving an LED light source while keeping the smartphone camera fixed to capture video of light reflections and deformations. [^3]\n\nTesting on 30 everyday items found in hotels or rental accommodations revealed the tool identifies hidden cameras with 94% accuracy. [^4]\n\nThe SweepLED device transforms a smartphone into a detector using a custom LED housing that costs less than seven dollars to manufacture. [^5]\n\nProfessor Jun Han from the KAIST team stated that SweepLED can spot hidden cameras 94% of the time with a processing period of just five seconds per object. [^6]\n\nThe SweepLED prototype combines 15 LED lights, a cable to attach to a phone, and AI processing to analyze reflection patterns. [^7]\n\nThe KAIST team tested the prototype on 30 different objects, reporting a high level of skill at identifying where hidden cameras are embedded or not. [^8]",
