RuView – See through walls with WiFi

Why This Matters

π RuView leverages WiFi signals and CSI data from ESP32 sensors to enable camera-free, non-invasive sensing through walls, providing insights into occupancy, vital signs, activity, and environment changes. This technology offers a privacy-preserving alternative to traditional cameras, with applications in security, health monitoring, and smart environments. Its development highlights the potential of WiFi-based spatial intelligence to transform how spaces are monitored and understood without additional hardware or intrusive methods.

Key Takeaways

π RuView

Beta Software — Under active development. APIs and firmware may change. Known limitations: ESP32-C3 and original ESP32 are not supported (single-core, insufficient for CSI DSP)

Single ESP32 deployments have limited spatial resolution — use 2+ nodes or add a Cognitum Seed for best results

Camera-free pose accuracy is limited (PCK@20 ≈ 2.5% with proxy labels) — camera ground-truth training targets 35%+ PCK@20; the pipeline is implemented, but the data-collection and evaluation phases (ADR-079 P7–P9) are still pending, so no measured camera-supervised PCK@20 has been published yet Contributions and bug reports welcome at Issues.

See through walls with WiFi

Turn ordinary WiFi into a spatial intelligence / sensing system. Detect people, measure breathing and heart rate, track movement, and monitor rooms — through walls, in the dark, with no cameras or wearables. Just physics.

π RuView is a WiFi sensing platform that turns radio signals into spatial intelligence.

Every WiFi router already fills your space with radio waves. When people move, breathe, or even sit still, they disturb those waves in measurable ways. RuView captures these disturbances using Channel State Information (CSI) from low-cost ESP32 sensors and turns them into actionable data: who's there, what they're doing, and whether they're okay.

What it senses:

Presence and occupancy — detect people through walls, count them, track entries and exits
