Ambient sensing — nothing to wear, nothing watching

Presence,
without a single camera.

Your home is already full of signal. We read the way it bends around people and turn that into awareness — for family, elderly care, and the quiet hours nobody's watching.

How it works

Three steps, no cameras, no wearables.

Emit

Every room you're in is already full of signal — your router never stops talking, thousands of times a second.

Reflect

When a person moves, those radio waves bend and scatter around them. We measure that distortion — the channel state — not the content of any signal.

Infer

A small on-device model translates those subtle changes into presence, motion, and stillness. Nothing leaves the home.

Sees through walls, not into your life

It knows you're home. Not what you're doing.

Most of what a home needs to know is structural — which room, how long, whether anything changed. Spectr reasons about your space the way a floor plan does: walls, zones, presence. Never a face. Never a frame.

Structure in. Presence out.

Built for

The moments that aren't emergencies — but matter anyway.

Family

Know who's home, without watching.

A glance tells you the kids are back, the dog's awake, the house is breathing. No notifications screaming at you — just presence, when you want it.

Elderly care

Quiet check-ins, dignity intact.

See that grandma got up at 7:14, made it to the kitchen, and is back in the living room — without a single camera in her home. She doesn't have to wear anything, push anything, or remember anything.

Nursery

Movement, breathing, stillness.

The signal picks up the smallest motion — even breathing patterns from across the room. Calmer than a baby monitor, more private than a camera.

Away mode

The hours nobody's watching.

Out of town? The system shifts. Any movement in the house becomes a quiet alert — not a siren, just a heads-up with context.

Built for the people, not just the building

Everyone you live with, in one quiet view.

Not a tracker. Not a feed. Just the shape of a normal day — who's home, who checked in, who's still asleep — held lightly, the way you'd actually want to know it.
