A new tool called RuView claims it can sense humans through WiFi signals alone. Developed by Cognitum, the product promises to detect presence without traditional cameras or sensors. The concept caught attention on Hacker News, where developers quickly debated whether the technology is technically feasible or just marketing hype.

The headline "Sense Humans with WiFi" strips the idea down to its core promise: perceiving people through wireless signals. Privacy and accuracy concerns dominated the Hacker News thread, with commenters questioning what data the system actually captures and how reliably it distinguishes humans from objects.

For developers building smart home or office systems, RuView represents an alternative to camera-based presence detection. Whether it delivers on that promise remains an open question until independent testing proves otherwise.
