Hacking wireless security cameras with a laser: from 120 meters away with a 100% success rate! 🛜📹 🔫☠️🥷🏻
Security researchers Yan He, Guanchong Huang, and Song Fang presented their security research last month on PIR (heat-based) motion sensors in wireless security cameras - and how to trigger them remotely from up to 120 meters away!
The authors tested 15 different wireless cameras, including Arlo Pro 3, Blink XT2, and Ring. With a 100% success rate, they were able to generate fake motion detections using the setup described below.
The idea is simple and ingenious at the same time: PIR sensors detect heat differences instead of images. That’s why a laser heating a tiny spot can successfully fool them.
Turns out those “Mission: Impossible” tricks are actually legit. Who knew!
