The nights you can't be there,
WhitSentry is.

Small sensors in the rooms where someone you love sleeps and lives. No camera. No microphone. Nothing to wear. WhitSentry alerts when breathing motion is no longer detected or a fall is detected, and a professional monitoring center can dispatch 911.

Starter kit $299. Monitoring from $34.99 a month. Coming soon.

Why WhitSentry exists

Whitney Allen was 22 and healthy. She went to sleep one night and did not wake up. No one knew until morning.

Her father built WhitSentry so that no one should die at home because no one was watching. It carries her name.

Whitney's story is told at whitneyallen.org.

Why WhitSentry

The tools we trust have a gap

Every product built to protect someone at home fails in the same quiet way. It needs something from the person it protects.

An adult daughter and her father share coffee and a quiet laugh at his kitchen table in warm daylight.

Wearables come off.

Watches, rings, and trackers only work while they are worn. People take them off to sleep, to shower, to charge, or just to get comfortable. The device ends up on the nightstand on the one night it mattered.

Pendants need a conscious hand.

A help button only works if the person can press it. The emergencies that matter most are the ones that take that ability away first. A button cannot help someone who is unconscious.

Cameras do not belong in bedrooms.

A camera in a bedroom is a trade most families will never accept, and they are right not to. Protection should not cost someone their privacy in the most private room of the house.

WhitSentry asks nothing of the person it protects. Nothing worn. Nothing filmed. Nothing to press.

The setup

How it works

Three steps. You can set it up in an afternoon, in your own home or your parent's.

A calm bedroom at night, lit only by the soft amber glow of a small wall sensor.
  1. A small warm-white sensor the size of a credit card plugged into a wall outlet, glowing soft amber.

    Plug in the sensors.

    Each sensor is about the size of a credit card and plugs into a wall outlet. One per bedroom, plus the rooms where your family spends the day. The sensors use the WiFi signal already in the home to sense the small motion of a chest rising and falling. No camera, no microphone, nothing to wear.

  2. Calibrate each room.

    The app walks you through calibration, room by room. First the room sits empty for about a minute. Then the person who lives there follows a few simple prompts, so the sensor learns their signal in that space. The app tells you exactly what to do the whole way through. If you rearrange the furniture later, the app prompts you to recalibrate so the system stays accurate.

  3. A woman sleeps peacefully under a linen duvet in a dark blue bedroom, a soft amber night light on the far wall.

    WhitSentry stands watch.

    From then on, WhitSentry is on duty around the clock. The hub runs on your home internet with cellular backup and its own battery, so it stays reachable if the power or WiFi goes out. If breathing motion is no longer detected or a fall is detected, WhitSentry responds in a ladder:

    1. A voice alarm in the house and a push alert to your phone, with a 60-second window to cancel if everything is fine.
    2. If no one cancels, calls, texts, and emails go to the contacts you chose, in the order you set.
    3. If no one responds, a professional monitoring center verifies the event and can dispatch 911.

You choose who gets called and in what order. The monitoring center steps in only if no one on your list responds. See it for yourself in the demo.

WhitSentry is not a medical device. It does not diagnose, treat, cure, or prevent any disease or medical condition. It alerts when breathing motion is no longer detected or a fall is detected. It is not a substitute for calling 911 directly when you or someone present is able to call.

Nothing you type here is stored or sent anywhere.

Privacy

Private by design

There is no camera. There is no microphone. There is no image of anyone, ever, because none is ever created.

The sensors read the WiFi signal already moving through the home to sense breathing motion. By default, WhitSentry ships in privacy mode: the biometric numbers are stripped out on the sensor chip itself, and only one simple state leaves the house: someone is breathing in this room. Nothing more granular leaves the house unless you turn it on.

We built default privacy mode this way because it is the only design a family should accept in a bedroom.

By default, the only thing that leaves the house is "someone is breathing in this room."

Honest limits

What WhitSentry will not do

A safety product that hides its limits is not one you should trust. Here are ours, stated plainly.

One sleeper per sensor, per room.

A single sensor reads one person in a room. Two people in the same bed read as one. A shared bedroom needs a bedside radar pod for each sleeper. We tell you this up front, before you buy.

A small fabric-wrapped hub the size of a deck of cards on a wooden bookshelf, one soft amber light.

The sensors need wall power.

Sensor nodes plug into outlets and stop sensing the moment the power goes out. The hub has its own battery and cellular backup, so within seconds of an outage it tells you and every contact that monitoring is down. It never goes silent without telling anyone. But sensing does not resume until the power does.

We prove our thresholds before we trust them.

Every detection threshold in WhitSentry is validated through a bench gate against explicit targets we hold ourselves to, then a live pilot in real homes, before it is allowed to trigger a real alarm. We do not ship a life-safety alert on a lab guess.

If a limit ever changes, we will say so just as plainly.

FAQ

Questions, answered plainly

A man in his seventies pours coffee in his sunlit kitchen, relaxed and at home.
Is WhitSentry a medical device?

No. WhitSentry is not a medical device. It does not diagnose, treat, cure, or prevent any disease or medical condition. It alerts when breathing motion is no longer detected or a fall is detected. It is a home safety product, in the same spirit as a smoke detector: it alerts on a physical signal so people can respond. It is not a substitute for calling 911 directly when you or someone present is able to call.

What exactly does WhitSentry detect?

Two things. It alerts when breathing motion is no longer detected for a person present in a covered room, and it alerts when a fall is detected. That is the whole claim, and we keep it that narrow on purpose.

Does it use a camera or microphone?

No. There is no camera and no microphone in any WhitSentry device. The sensors read the WiFi signal already in the home to sense breathing motion. No image or audio of anyone ever exists.

What happens when an alert fires?

First, a voice alarm in the house and a push alert to your phone, with a 60-second window to cancel if everything is fine. If no one cancels, WhitSentry calls, texts, and emails the contacts you chose, in your order. If no one responds, a professional monitoring center verifies the event and can dispatch 911.

What about false alarms?

The 60-second cancel window exists for exactly this. Rolled over in an odd position, sensor got confused, all fine: cancel with one tap from your phone. And a trained human at the monitoring center verifies every event before 911 is ever dispatched. No one sends an ambulance on a sensor reading alone.

Does it keep working if the power or internet goes out?

The hub does. It has a battery and cellular backup, so if the power or WiFi goes out, it alerts you and your contacts within seconds that monitoring is down. The room sensors plug into wall outlets, so sensing itself pauses until power returns. We would rather tell you that plainly than let the system go quiet without a word.

Can it cover two people in the same bedroom?

Yes, with one addition. A room sensor reads one sleeper per room, so a shared bedroom needs a bedside radar pod for each sleeper. The pod is $79.

Does my mom or dad need to wear anything, press anything, or learn an app?

No app for them, no wearable, and nothing to press. There is a one-time guided setup you do together in their home, room by room. After that, you manage everything from your own phone. Day to day, WhitSentry asks nothing of the person it protects. It is just their home.

Who sees the data?

Almost no one, because by default almost none exists. WhitSentry ships in privacy mode: biometric numbers are stripped on the sensor chip itself, and the only state that leaves the house is "someone is breathing in this room." Nothing more granular leaves the house unless you turn it on. You see household status in the app. The monitoring center sees an event only when the ladder reaches them.

When can I buy it?

Soon. WhitSentry is finishing validation and certification before launch, because a life-safety product has to earn its alarms before it ships. Join the waitlist and you will be first in line when it launches.
