How Dísir Works
Quiet sensors, a private in-home network, and gentle helpers — working together in every room.
mmWave Radar Sensors
Discreet sensors watch over each room — sensing presence, motion, and falls through the air itself, never recording images.
Zero Cameras or Mics
No cameras. No microphones. No invasive surveillance — complete dignity, everywhere it matters most.
100% Local Processing
Everything stays on a small hub inside the home. Nothing is streamed to the cloud, so your family's life stays private.
Encrypted, End to End
Every sensor speaks to the home hub over an AES-128 encrypted mesh, and the link to your phone is sealed end-to-end — so no one, not even us, can read your family's day.
A Self-Healing Network
The sensors run on their own low-power mesh — never your home Wi-Fi. If one device drops, the others quietly re-route around it, so coverage simply never goes dark.
Door & Entry Sensors
Slim contact sensors note the rhythm of doors — the morning paper, a wander toward the front door at 2am — and let you know only when something is truly out of the ordinary.
Adaptive Smart Lights
Lights follow the person, not a schedule. A soft amber path lights the way to the bathroom at night, and warm light rises gently when it's time to be up — no fumbling, no glare.
Check In, Without Looking In
Open the app and breathe out. You'll see where they are and that their day is on track — never a video feed, never a listening device.
- ✓Routine tracking — know that medications are taken and meals are eaten.
- ✓Instant alerts — be notified gently and immediately if a fall is detected.
- ✓Peace of mind — the reassurance of glancing into the next room, from anywhere.
The Cloud · What They Don't Show You
Where Does Your Data Actually Go?
Most "smart" home care keeps your loved one safe by sending their most private moments out of the house — to company servers you will never see. Here is the journey your family's data takes the moment a cloud device is switched on.
- Your data leaves the home
- Stored on corporate servers
- Used for their own purposes
- Goes down with the internet
- Cameras & always-on microphones
Safety shouldn't cost you your privacy.
With Dísir, it doesn't.
Why We Created Dísir
In ancient Norse folklore, the Dísir (pronounced “DEE-sir”) were benevolent, invisible guardian spirits. They watched over households to protect families from unseen harm — working quietly in the background, never invading the privacy of the home.
We built Dísir Ambient Care to bring that protective spirit into the modern age.
Our Mission
We believe safety should not require surveillance. Dísir Ambient Care offers a local-first, camera-free system that monitors daily rhythms, spots unusual patterns, and alerts caregivers — all while keeping your family's data secure inside the home.
