Tevity Sense uses the WiFi you already have to detect presence, motion, and room-by-room occupancy — through walls, in the dark, with zero cameras. Just physics.
How it works
Start with the hardware you already own and scale into a full multi-floor sensing mesh — every layer runs on-premise.
Monitor signal-strength fluctuations from your existing router to detect presence and coarse motion in a single room.
Low-cost ESP32 nodes passively extract per-subcarrier Channel State Information from your router for room-accurate sensing.
Every WiFi device already emits packets. Nodes sense them all at once — more transmitters means more spatial diversity and accuracy.
Signals fuse into presence, motion, and zone occupancy across every room — all processed locally, privacy first.
Capabilities
A single sensing layer that replaces a stack of cameras, motion detectors, and access logs.
Know which rooms are occupied in real time — through walls, in the dark, with no line of sight.
Detect movement and motion levels across zones from the disturbances bodies create in WiFi signals.
WiFi passes through walls and furniture, so a small mesh of nodes covers rooms a camera never could.
Count how many people are in each zone for utilisation, capacity, and safety — no identities, ever.
Flag intrusion, loitering, and after-hours presence in sensitive zones with severity scoring.
Per-zone occupancy, dwell time, traffic flow, and peak-period insights across every floor of your building.
Use cases
Building-wide intrusion, loitering, and after-hours presence detection across multi-floor offices.
Room presence and occupancy awareness in wards and clinics — without invasive cameras.
Footfall, dwell time, and zone heat maps to optimise store layout and staffing.
Occupancy-aware HVAC, lighting, and space utilisation that pays for itself.
Dignified, camera-free monitoring with inactivity and night-time movement alerts for assisted living.
Book a consultation and we'll map your building, scope a deployment, and show you a live sensing pilot — no cameras, no cabling.
