Safety & Service Information

Last updated: 8 September 2026

This page explains, in plain language, what ALVIA can detect, what it cannot, and what to do when something happens. It is written to be read before you buy and again after the equipment arrives. It is not the contract — the binding version is in our Terms of Service — but nothing here is less true for being readable.

ALVIA is an assistive wellbeing and safety service. It adds a layer of attention to a home. It is not a medical device, not an emergency-response service, and not a substitute for the care people give each other. In an emergency, call 112.

1. Fall detection

The wearable watches for movement patterns consistent with a fall that may need attention, and can raise an alert without anyone pressing anything. That is the useful part. Here is the part that matters just as much:

  • Not every physical fall produces an alert. ALVIA does not simply record every time someone goes to the ground.
  • The system looks at what happens around the event, not only the impact. It considers movement before, during and after a possible fall.
  • Continued normal movement after a possible fall may mean no alert is raised. If the pattern suggests the wearer got up and carried on, the event may not meet the criteria for an alert — even though a real fall happened. This is deliberate. Without it, ordinary abrupt movements would produce so many false alarms that the real ones would stop being believed.
  • False positives and false negatives are both possible. Like any automated detection system, ALVIA will sometimes alert when nothing serious happened, and will sometimes stay silent when something did.
  • Silence is not evidence. The absence of an alert does not prove that no fall occurred, and it does not prove the wearer is uninjured or safe.
  • Movement data cannot tell us about injury. ALVIA cannot determine from movement alone whether someone has been hurt. Someone can get up and walk after a fracture.

If you are worried about someone, check on them. ALVIA is there to tell you about things you would otherwise miss — not to tell you when it is safe to stop paying attention.

2. Prolonged immobility

ALVIA also looks for prolonged inactivity that may be worth attention.

  • Sleep and ordinary rest are normal. A system that treated every quiet hour as an emergency would be useless within a week, so ordinary rest is not automatically treated as a concern.
  • Because of that, not every emergency produces enough detectable inactivity to be recognised as one.
  • As with falls, immobility detection cannot guarantee that every emergency will be identified.

3. The panic button

If the wearer needs help and is able to act, the Panic button does not rely on automatic fall classification: one press requests an alert.

Please make sure the person wearing it knows the button exists, knows what it does, and is not afraid of using it "for nothing". A button nobody dares to press protects nobody.

Like every other function, the button needs working equipment and a working connection to get its alert out.

4. Connectivity and equipment

ALVIA works when a chain of things works. The wearable must be worn and have sufficient battery power. The gateway must be plugged in and positioned so it covers the rooms actually used. The two must be within wireless range of each other. The gateway must have mobile coverage where it stands. Our systems and the networks in between must be reachable.

Any link in that chain can fail for reasons no one controls — a power cut, a mobile outage, a flat battery, a gateway unplugged to free a socket. When a link fails, detection may be delayed, incomplete or absent. Where the wearable stops talking to the gateway, ALVIA can alert you to the disconnection itself, after a short confirmation period so that a momentary radio glitch does not wake the household. That is a signal that something changed, not a location: ALVIA does not use GPS and cannot tell you where anyone is.

5. Alerts and who responds

When ALVIA raises an alert it notifies the contacts you designated. The contacts decide what happens next. ALVIA does not operate a staffed emergency centre and does not dispatch an ambulance, the police, a carer or a doctor.

Generating an alert is not the same as delivering it. Delivery depends on mobile networks, on the recipient's phone being on and reachable, on the contact details being correct, and on the message not being blocked or silenced. Keep those details up to date, and tell the people on the list that they are on it and what you expect them to do.

6. Emergency services

ALVIA does not replace 112. It does not call emergency services automatically, and it does not pass information to them, unless a separate service you have signed up to explicitly says otherwise. If someone is in danger, call 112 yourself — do not wait to see whether an alert arrives.

7. Getting the most out of it

  • Place the gateway centrally, not in a cupboard or behind a metal appliance.
  • Keep it powered. If the socket is needed for something else, find another socket rather than unplugging it.
  • Replace the wearable battery when the device warns you, and do not ignore warnings about the equipment.
  • Encourage the wearer to wear it during the hours they are alone, which are the hours it matters.
  • Review your designated contacts twice a year, and whenever a phone number changes.
