Awareness

Notice the little changes. Act when it really matters.

You can't call every hour. You shouldn't have to.

Anyone with a parent living alone knows the quiet arithmetic: the lunchtime call that goes unanswered, the counting back to when someone last spoke to them. Most days nothing is wrong - but you only ever know that afterwards.

sensea closes that gap. It learns what a normal day looks like in their home, and speaks up to the people they choose the moment a day stops looking normal. Nothing to wear, nothing to press, no camera watching.

How it works

What sensea actually does.

sensea is a small smart home-care device that sits in your parent's home and learns what a normal day looks like there. When the day starts to look different, the family members they choose get a clear message on their phone. That is the whole idea.

01 - Learning

It learns the rhythm of the home.

Every home has a rhythm. Up around seven. Living room by eight. Quiet in the afternoon. Lights off by eleven. sensea spends its first days simply learning that rhythm, without anyone doing anything.

Once it knows what normal looks like, it can tell you when something shifts. And it understands that not every shift is the same. Some things happen in a moment, like an odd or sudden movement. Others build slowly, like mornings that keep starting later, or movement through the home that gradually slows over weeks. sensea notices both, and treats them differently.

08:00Living room
14:00Quiet afternoon
23:00Lights off

In a momentAn odd or sudden movement that does not fit the rhythm of the day.

Over weeksMornings that keep starting later. Movement through the home that gradually slows.

02 - Sensing

How it senses without watching.

sensea uses four kinds of sensors. None of them is a camera. None of them is a microphone. Nothing needs to be worn or pressed.

MovementReads movement and position in the room as an abstract pattern. It knows the usual pace of the home, and it recognises when a movement is odd or sudden - the kind that does not fit the normal rhythm of the day.

WarmthA soft, low-resolution heat reading that confirms whether the radar saw a person. A curtain in the wind or a cat jumping off the sofa has no human heat signature, so it gets filtered out before anyone is bothered.

VibrationFeels sudden physical impacts in the room. When an odd movement also comes with a physical jolt the sensors can feel, that adds one more piece of evidence that something real happened.

EnvironmentLight, temperature and air quality add context. A kitchen that warms up at lunchtime tells its own story.

It knows what is happening outside, too.

The home does not exist in a vacuum. sensea also listens to weather, local conditions and regional alerts, so a heatwave changes what a warm living room means, a dark winter morning explains a later start to the day, and a normal January is not judged by the standards of July.

When conditions in your parent's area deserve attention - an extreme heat warning, say - the family knows without following the local news from two hundred kilometres away.

Designed with privacy in mind

Look out for them, without them feeling watched.

sensea senses the shape of the room and the warmth of the people in it. No faces. Nothing is recorded.

Giving you enough context to act. Nothing more.

The roomWhat sensea sees

Day to day, everything sensea reads is processed inside the device.
Only when something unusual is confirmed does a short piece of context leave the home, and only to the people your family has chosen.

03 - Verifying

Three checks before anyone is bothered.

The single biggest reason families abandon home safety products is false alarms. When sensea notices an odd or sudden movement, nothing reaches your phone until the evidence agrees with itself.

01 Radar noticesA movement that does not fit the normal pattern.
02 Thermal confirmsThere is actually a person where the movement happened.
03 Accelerometer adds evidencePhysical proof when an event came with a real impact.
People decideOnly when the picture holds together does sensea alert the trusted circle, together with a short heat clip that lets a person make the final judgement.

Radar detects. Sensor fusion confirms. People decide.

04 - Receiving

What your family actually receives.

Not a live feed. Not a dashboard to check obsessively. On a normal day, the app simply shows that things look normal. sensea speaks up in two different ways, because not everything it notices is the same kind of news.

When something sudden happensAn alert, right when it matters.

A sudden movement that does not fit the usual pattern comes with a short heat clip, roughly sixty seconds around the moment it noticed. This is not camera footage. It is the same soft warmth pattern the device sees: enough to understand what happened, never enough to see a face or what someone is wearing.

The home itself can also be the reason for an alert: a room that has stayed very hot for a long stretch, or air that has turned very poor. There is no clip here, because there is nothing to watch. The alert simply shows what sensea measured and for how long.

Either way, the person receiving it can judge the situation and decide what fits: a phone call, a visit, asking the neighbour to check in, a nudge to open a window, or nothing at all, because it turned out to be an ordinary moment.

When something shifts slowlyA quiet observation.

A day that starts unusually late, or a rhythm that has been changing over weeks. There is no clip, because there is no moment to look at. The family simply gets a quiet observation: here is what changed, here is when.

Often the right response is nothing more than a phone call that would have happened anyway, just a few days earlier.

In both cases, sensea never decides for the family. It gives the people who care enough context to decide well. Who gets access is entirely the family's choice. A daughter, a son, a neighbour two doors down, a close friend. Every family builds its own trusted circle, and nobody outside it ever sees anything.

05 - Beyond the room

It understands more than it sees.

sensea directly senses everything within its view. But the rhythm of a home is bigger than any one room, and sensea understands that too.

A home tells its story as a whole. When someone spends the evening in a room the device cannot see, the device still knows how the day usually winds down: when the living room goes quiet, when the bedroom is usually entered, when the home settles for the night. If that pattern breaks - if the bedroom stays empty on a night it never does, or the day never winds down the way it always has - that change shows up in the rhythm, even though it happened out of view.

So being out of sight does not mean being out of the picture. The routine itself carries the information.

Where it belongs

The living room, the bedroom, or both - wherever daily life happens most. One device covers its own room and reads the rhythm of the wider home; a second, typically bedroom plus living room, covers the day and the night. Most families start with two.

To be clear

What sensea is not.

Not a camera.Nothing is filmed. The only thing ever shared is a soft heat pattern, and only when something sudden and unusual happens.
Not a microphone.It cannot hear conversations.
Not a wearable.There is nothing to remember, charge or press.
Not a medical device.sensea gives families awareness, not diagnoses.
Not surveillance.Your parent lives exactly as before. The device learns quietly and speaks up only when something is different.

A sense of home, restored.

Why we built sensea

Built from years

inside care homes.

The care home system has long held insufficiencies, and we wanted to make a product that meets people where they are and truly relieves them of their worry. sensea exists to close that space. Quietly, and on the family's terms.

"sensea has created a technology solution that I can be confident works when we need it and unobtrusively maintains the dignity of independence when all is well." - The Henley on Broadwater

FAQs

Is my loved one being watched or recorded?

sensea has no camera and no microphone. It doesn't record video or audio of daily life, and it never builds an image of a person or a room. It senses movement, presence, and the conditions of a space - not identity. The one moment any visual exists is a brief, event-triggered thermal view (a heat outline, not a recognizable image) sent to a trusted contact, available only briefly and never stored. In normal daily life, there is nothing to see and nothing being kept.

What happens when something goes wrong - and who decides?

When sensea notices something unusual, several independent layers check it before anyone is alerted - radar detects it, thermal and impact confirm it. If the moment still needs judgment, a trusted contact receives a notification and decides whether to reassure, ignore, or escalate. sensea doesn't call emergency services on its own or make medical decisions. A person who knows your loved one makes the call.

Does my parent have to wear or charge anything?

No. sensea is entirely contactless. There is nothing to wear, nothing to press, nothing to remember to charge, and nothing that depends on your parent doing anything at all. It works quietly in the background of the home - which is exactly why it keeps working on the days a pendant or a smartwatch would have been left on the nightstand.

Will this feel intrusive - or make my loved one feel surveilled?

sensea is designed to protect independence, not supervise it. Because there's no camera, no microphone, and nothing to wear, there's no sense of being filmed or monitored going about a normal day. Most of the time it does nothing visible at all. It's meant to give your loved one privacy and a family peace of mind at the same time - presence in the background, not a watchful eye.

What is sensea - is it a medical or emergency device?

sensea is a home awareness device, not a medical or emergency-response product. It helps families stay quietly connected to the rhythm of an independently living relative's day and notice when something is out of the ordinary. It doesn't diagnose, doesn't provide medical advice, and isn't a substitute for emergency services or professional care.

Our Story

The team behind sensea

Three founders, three stories. What we saw, why we built this, and what we want families to feel.

Sebastian Wünsche

Co-Founder & CEO

Before sensea, we worked closely with care homes and care providers. We saw how impossible it is for caregivers to be everywhere at once, even at their absolute best. Unusual inactivity, isolation, a quiet change in someone's routine - these are so often noticed only after the fact. Not because people don't care, but because the system is stretched and the tools aren't good enough. So we went from care homes to the home environment: sensea brings that awareness into the place people most want to stay - their own home.

Tobias Borlinghaus

Co-Founder & CTO

Like so many people I've spoken to since starting this journey, my story begins with someone I love. My wife's grandfather lives alone in the beautiful Provençal countryside - far from family, far from us. Not knowing how he was doing, while feeling deeply responsible for his wellbeing, was a quiet but constant pain the entire family carried. The only solutions we could find were cameras or smart home sensors - neither of which felt right.

Damian Mavrudis

Software Engineer

We identified significant demand for smart sensor solutions in the private elderly care sector. While working with other smart sensors in this sector, we became increasingly frustrated by their limited features, poor usability and unreliability. So, we decided to address these issues and develop our own solution.
