Visualize the electromagnetic environment of your home in real time. Know what signals are passing through your walls and where they go.
Passive RF sensing · Counter-surveillance · Open source

WiFi signals pass through every wall in your home. With the right tools, anyone can detect movement, presence, even posture from outside — and that's just ground level. Consumer drones now carry RF sensing payloads that map activity from above. Robots.fm builds the technology to detect surveillance from every direction — and defend against it.
WiFi-based motion detection through solid walls is published research and shipping in commercial products. Using nothing but existing WiFi signals, these systems detect presence, movement patterns, breathing rate, and posture — from outside your home, without your knowledge.
Consumer drones are cheap, autonomous, and increasingly carry RF sensing payloads. A $500 drone can loiter above your home and map activity using the same WiFi signals passing through your roof. Swarm coordination makes this scalable. The threat isn't hypothetical — the hardware already exists.

Required for RF-based surveillance. No line of sight needed.
WiFi-through-wall sensing is real and advancing fast. Research labs and commercial products already use RF signals to detect people through solid walls. Autonomous drones extend that reach to airspace — mapping activity from above using the same signals leaking through your roof. Robots.fm exists to put detection and defense in the hands of the people being watched — walls, sky, and everything between.
Real ethical AI means transparency, open source, and building tools that protect people rather than surveil them. Every model we ship is inspectable. Every algorithm is published. Privacy isn't a feature — it's the founding principle.
democratize.io handles software and AI ethics. Robots.fm handles hardware, sensing, and consumer security. Same founding team, shared mission.
Every algorithm, every model, every detection method — open source and inspectable. If it runs in your home, you should be able to read the code.
Not enterprise surveillance repackaged. Built for people who want to understand and control the RF environment in their own space.
RF signals from your WiFi router bounce off walls, furniture, and people. When something moves, the signal changes. Robots.fm captures those changes and turns them into a spatial awareness map — showing you exactly what's happening in and around your space.

The system builds a continuously updated model of activity across every room. Not cameras. Not microphones. Just the RF signals already passing through your walls — turned into awareness you control.


Consumer RF security that puts you in control of your own space. No subscriptions. No cloud dependency. Hardware you own, software you can read.
Visualize the electromagnetic environment of your home in real time. Know what signals are passing through your walls and where they go.
Movement detection without cameras. Know when something enters or moves through your space using only passive RF observation.
The core defense: if someone is using WiFi signals to watch through your walls, make yourself harder to see.
No black boxes. Every detection algorithm is open source. Verify exactly what the system does and doesn't do.
Detect drone activity and aerial RF surveillance in your airspace. The same sensing that finds movement through walls detects autonomous platforms overhead.
Deploy multiple nodes for spatial triangulation. Cover your full environment — walls, yard, airspace — with coordinated volumetric awareness.
Robots.fm and democratize.io share a commitment to building in the open. The RF sensing algorithms, detection models, and visualization tools are all open source — because security you can't inspect isn't security.
