Can Your WiFi Router Really See You Through Walls?

MIT and Carnegie Mellon researchers have turned WiFi routers into motion detectors and night vision cameras using AI models like DensePose and LatentCSI. Alex explains how WiFi signals capture body movement through walls and how similar “motion sensing” tech is already inside consumer mesh WiFi and ISP routers, how WiFi imaging works with MIMO antennas and RF tomography, why it’s becoming a privacy concern, and what your router might really be seeing. This creepy technology is starting to appear in consumer mesh WiFi 7 systems and ISP-provided routers from Linksys and Xfinity, under smart home “motion detection” or “presence sensing” features. While designed for smart home automation, these same systems use similar CSI-based signal reflection analysis to detect human presence and movement like radar, raising serious privacy and security concerns. Alex compares the WiFi DensePose and LatentCSI (based on Stable Diffusion 3) research tech with commercial router motion detection, breaking down how multipath signal processing, RF tomography, and MIMO antenna arrays enable these routers to see through walls. #techtalk #networkengineer #homenetworking #technews #security #wifi #homeautomation
