Fall detection for seniors: wristband, camera or sensors? — VitalKeep

Falls are the leading cause of injury among older people who live alone. So when a family starts looking for solutions, the first question is usually technical: what detects a fall best — a wristband, a camera or sensors? The honest answer is that each technology has its strengths, and that the real difference is not in the lab, but in everyday life. In this guide we go through the three most common options, with their real pros and cons, so you can decide calmly and without brochures in the way.

Wristband or pendant with fall detection

An accelerometer on the wrist or around the neck recognises the pattern of a fall and sends an automatic alert. Many models add an SOS button to call for help.

Pros:

• It goes with the person around the whole house, and even outside.
• It detects the fall at the moment it happens, without anyone watching.
• It is discreet: nobody needs to know they are wearing it.

Cons:

• It only works when worn. On the bedside table it detects nothing.
• Slow falls — sliding down while holding onto furniture, slipping off a chair — are hard for any accelerometer to recognise.
• Someone has to remember to charge it.

AI cameras

Cameras that analyse the image in real time and recognise postures: if the person is on the floor, they raise an alert.

Pros:

• Nothing needs to be worn.
• They can detect slow falls and people lying immobile on the floor.

Cons:

• They are invasive. A camera in the bedroom or bathroom — exactly where most falls happen — is a line many families don’t want to cross. Neither do many older people: they cover them or unplug them.
• They only cover the room they point at. Covering the whole home multiplies cost and intrusion.
• They create a feeling of being constantly examined that changes how the person lives in their own home.

Presence and activity sensors

Small devices — in VitalKeep’s case, smart plugs — that sense presence and movement room by room, with no image and no sound. They don’t “see” the fall: they detect its consequences, such as no movement where there should be some, or a routine that suddenly breaks.

Pros:

• Zero effort for the person: nothing to wear, press or charge.
• No cameras, no microphones: privacy stays intact.
• They cover what the other technologies miss: the fall nobody witnessed and the device left in a drawer.

Cons:

• They don’t detect the impact at the exact instant: they notice something is off minutes later.
• They need a few days to learn the normal routine of the home.

The real problem: the device that doesn’t get used

Here is the key that almost no brochure mentions. Industry studies keep finding the same uncomfortable pattern: a large share of the time, the technology isn’t where it should be. The wristband stays on the charger, the pendant in a drawer “because I’m not going out today”, the button unpressed so as not to bother anyone. It is estimated that around 80% of falls that were attended late didn’t fail because of the technology, but because the device wasn’t being worn or wasn’t pressed.

Put another way: the best fall-detection technology is the one that keeps working when the person doesn’t cooperate. That is the real bar to measure against.

The passive approach: a safety net that depends on no one

That is why VitalKeep combines two layers that back each other up:

• The wristband (€30), with automatic fall detection and an SOS button, for the immediate alert when it is worn.
• The smart plugs (€60 each), which passively sense presence and activity room by room. If the wristband stays on the bedside table, the home still tells you what matters: whether there is movement where there should be.

If something falls outside the normal pattern — a morning with no activity in the kitchen, a long silence where there was always routine — the app notifies the family, several caregivers. Only when there is something worth looking at: no noise, no daily reports, no alarmism.

And the SOS button is still there for the moments when your relative wants to ask for help actively: pressing remains the fastest route when the person can and wants to. The difference is that it stops being the only route. If one day they cannot press, or the wristband stayed on the charger, the home keeps telling you what matters.

So, which one should I choose?

If your mum or dad is happy wearing a wristband all day and charges it faithfully, a good wristband covers a lot. If you want maximum detection and privacy is not a concern in your family, cameras exist. But if you want a realistic safety net — one that also works on the days the wristband stays on the bedside table — the passive approach with sensors is today’s most sensible balance between care, privacy and cost.

One last piece of advice: whatever you decide, involve your relative in the choice. Technology chosen with the person gets used; technology imposed on them ends up in a drawer. And a fall detector in a drawer detects nothing.
