How it works
Presence from invisible signal.
Spectr turns ordinary WiFi into a real-time sensing fabric — pose, breathing, heart rate, and room occupancy from radio signals alone. No cameras, no microphones, nothing to wear.
01 — The signal is already there
Your home is never truly still.
Wi-Fi signals move through walls, around furniture, and across every room, thousands of times a second. Spectr doesn't create a new signal or install cameras throughout your home. It simply observes how the space affects what already exists.
02 — People change the space
Presence leaves a pattern.
When someone enters a room, sits down, walks past a doorway, or lies quietly in bed, the radio environment shifts. Signals bend, scatter, and reflect differently around the human body. Spectr measures those tiny changes over time and learns the difference between an empty room and a living one. Movement has a pattern. Stillness has a pattern. Occupancy has a pattern.
03 — Understanding happens locally
The intelligence stays at home.
Those signal patterns are processed by a small local model that infers presence, motion, and room activity. No images are captured. No audio is recorded. No visual representation of your home is ever created. The system understands that something changed — not what you look like.
That's the whole idea.
One home. One signal environment. One private layer of awareness. No cameras. No wearables. No compromises.
See without cameras. Sense through walls.
Cameras break privacy. Sensors miss context.
Most “smart spaces” either record you or guess at you. Spectr does neither. It reads the radio signals that are already saturating every room and turns them into structured, on-device intelligence — no lenses, no microphones, no cloud.
Cameras & Wearables
- Lenses capture faces, skin, identity
- GDPR / HIPAA exposure by default
- Dead zones behind walls and furniture
- Fail in smoke, dust, darkness
- Wearables assume willing, charged users
The Spectr Approach
- Radio signals only — no images captured
- Physics-based: Fresnel zones, multipath
- Through walls, furniture, rubble, fog
- Works in the dark, through smoke
- Zero user compliance — ambient by design
A camera in the bathroom is a liability. A camera in a rubble field is a ghost.
Not just “someone's here.” Exactly where.
A single sensor tells you a room is occupied. A mesh tells you where.
Full-room coverage
Multiple sensors working as one. A small group of nodes talk to each other and figure out exactly where every person is standing — not just whether the room is occupied.
Through rubble
The Spectr rescue kit spots survivors buried under collapsed concrete and marks each one with a 3D position and an urgency score — all without needing to see or hear them.
Based on real science
Radio waves bend around people and objects in predictable ways. Spectr reads those bends and reconstructs what's in the room — like how your eyes know something is close by how light focuses, but with radio instead of light.
Plays well with others
If you already have cameras, radar, or lidar, Spectr plugs in and merges its view with theirs. One combined map — Spectr covers the dead zones and privacy-sensitive spots, the other sensors handle the rest.
A single sensor can tell you someone is breathing in the room. A mesh of a few sensors can tell you a 1.7m adult, seated, 3.2m from the south wall, heart rate 68 — without a single camera. The difference is simply that multiple ears hear the same sound from different angles, and geometry does the rest.
CSI at 20 Hz across 56-192 subcarriers becomes pose, breathing, and heart rate — all inside a 55 KB model.
Built for every space
One sensing fabric. Six industries.
Healthcare
Elderly care & apnea
Fall detection with sub-2-second alert latency. Contactless breathing and heart rate during sleep — no wearable to forget or charge. Ideal for aging-in-place and non-critical bed monitoring.
Retail & Hospitality
Queue and dwell analytics
Queue length, table turnover, dwell heatmaps, occupancy counts — all without a single camera in the space. GDPR-clean by design.
Smart Buildings
HVAC & lighting automation
Room-level occupancy drives HVAC setpoints and lighting. Works behind walls, no door sensors, no PIR blind spots.
Industrial Safety
Cobot & confined spaces
Proximity alerts for cobots, exclusion-zone enforcement, worker monitoring in confined spaces. Works through smoke, dust, and fog where cameras fail.
Search & Rescue
Survivors through rubble
Spectr's disaster response kit detects vital signs through 30 cm of concrete. START-triage classification and 3D survivor localization without opening the wreckage.
Smart Home & Office
Ambient presence automation
Lights that follow you room-to-room. Meetings that book themselves when occupancy changes. No motion sensors, no cameras — just physics.
Technical capabilities
What the model sees.
Every capability runs on-device as a small, focused model. No cloud, no upload, no raw signal leaves the node.
