RuView Enables Camera-Free Through-Wall Human Tracking

In late February 2026, open-source RuView (formerly WiFi DensePose) surged GitHub trending lists by demonstrating camera-free, through-wall human tracking using WiFi Channel State Information and inexpensive ESP32-S3 nodes. The system maps 17 body keypoints, senses breathing and heart rate, and runs locally on a Rust edge stack for as little as $54 in hardware. Security experts warn it enables stealth surveillance, prompting RF shielding and CSI-randomization defenses.
