Know they're okay without watching.
Beryl learns the rhythm of the home and turns quiet movement patterns into simple family insight. No cameras. No microphones. No wearable your parent has to remember.
Bathroom activity and morning movement match her usual weekday pattern. No check-in needed right now.
For families who want a camera-free way to check on aging parents without turning care into surveillance.
The space between "they're fine" and "something happened"
Cameras feel invasive
You can't put a camera in your dad's bathroom. You shouldn't have to watch your mom on a screen to know she got out of bed today. There has to be a better way.
Wearables get forgotten
Medical alert pendants only work if your parent agrees to wear them. Most don't. The device sits on a dresser, dead, while the people who need it pretend everything is fine.
Phone calls aren't enough
You can call five times a day. You'll still be guessing. You need real, ambient awareness — the kind you'd have if you lived next door. Not surveillance. Awareness.
What other tools miss
The riskiest moments often happen outside the frame.
Most families already have pieces of a safety plan. The problem is the quiet gap between check-ins, cameras, and devices your parent has to remember to wear.
Cameras can show a live feed, but they create privacy problems in bedrooms, bathrooms, and the very rooms where families worry most.
A button on the dresser cannot help during a quiet change in routine. The system depends on the person remembering and accepting it.
A parent can sound fine at noon and still have an unusual morning. Calling more often does not give you the rhythm of the home.
Beryl looks for missed routines, unusual inactivity, and meaningful shifts without cameras, microphones, or anything to wear.
A moment Beryl is built for
Hypothetical example for product demonstration. Beryl is not a medical device and does not diagnose, treat, or guarantee emergency detection.
Earlier context
Not more noise. A clearer reason to check in.
The emotional value of Beryl is not a dashboard full of data. It is the moment you know something changed soon enough to act with care.
Instead of watching a camera feed or hoping a pendant is being worn, Beryl gives your family a quiet signal when the normal rhythm of the home looks meaningfully different.
How Beryl actually works
Five small sensors. No cameras. No microphones. No wearables. Here's what's actually happening inside your parent's home.
Plug in five nightlights
Beryl comes as five small devices shaped like squirrel nightlights. You place them in key rooms — bedroom, bathroom, kitchen, living room, hallway. They look like decor. No drilling, no installer.
Beryl learns their normal
Using ambient WiFi signal patterns — not images, not audio — Beryl quietly maps the rhythm of the home. When the coffee maker runs, when the bathroom door opens, when someone moves between rooms.
You see what matters
A simple family dashboard, shared across siblings. You don't get blasted with notifications. You get a gentle alert when something genuinely changes from baseline — and the data to know what to do next.
Beryl uses Wi-Fi Sensing (a technology also known as WLAN sensing or 802.11bf), which detects movement and presence by measuring how WiFi signals reflect off objects and people in a space. No image is captured. No audio is recorded. The only data leaving your parent's home is a pattern of activity timestamps — no different than a smart thermostat reading temperature.
Everything you need to check in without hovering
Beryl gives families a simple way to see the rhythm of the home, spot meaningful changes, and know when to check in.

The honest FAQ
WiFi signals naturally bounce off everything in a room — walls, furniture, people. Beryl's sensors measure how those reflections change over time. When someone walks into the kitchen, the signal pattern shifts in a specific, detectable way. The sensors only see patterns, not pictures. There's no camera, no microphone, and nothing visual is ever captured or stored.
Beryl requires WiFi to function — it's the sensing medium. If WiFi goes down, you'll see "connection lost" on your dashboard within minutes.
Beryl is built to be quiet on purpose. It focuses on genuine deviations from the learned baseline — a missed morning routine, prolonged stillness in unusual places, dramatic changes in bathroom frequency. Most days you'll simply see the dashboard showing a normal pattern, which is the whole point.
Ring and Nest are camera-based security systems built around the assumption that you want to watch a feed. Beryl is the opposite philosophy: ambient sensing for care, not surveillance. There is no video to log into. There is no "live view." If your parent would refuse a Ring camera, that's exactly the person Beryl is for.
Only the family members you invite to the dashboard can see your parent's activity data. We don't sell data — we have a paid subscription specifically so we don't have to. Data is encrypted in transit and at rest. Your parent's activity stays between you and the family members you choose to include.
