Fall Detection Without Wearables
Pendant alarms and fall-detection watches only work when four things line up: the device is being worn, it is charged, it is within reach, and the person is able to press it or trigger it. In real life, one of those four fails often. The pendant sits on the bedside table, the watch is charging in the kitchen, or the person who has fallen is hurt, confused, or unconscious and cannot press anything.
This guide explains why wearables fail in practice, how passive room-based fall detection removes each of those failure points, where wearables still make sense, and what each approach costs in Australia.

Why wearable fall alarms fail in practice
A wearable alarm is a good idea on paper, but it depends entirely on the person it is meant to protect. Every step in the chain is a chance for it to fail, and the failures cluster around exactly the moments when a fall is most likely.
The most common failure is the simplest one: the device is not on the person. Pendants get taken off for showers and left off afterwards, even though the bathroom is one of the riskiest rooms in the house. Watches get taken off to charge overnight, even though many falls happen on night-time trips to the toilet. Some older people find pendants stigmatising and quietly stop wearing them altogether.
The second failure is harder to talk about but just as important. Many falls leave the person unable to press a button. A fall can cause a loss of consciousness, a serious injury, or shock and confusion, and a press-to-alert device is useless in exactly those situations. Automatic fall-detection watches help, but they still need to be worn, charged, and fitted correctly to work.
Must be worn — Removed for showers, sleep, and charging, which are among the highest-risk times for a fall.
Must be charged — A flat battery means no protection, and charging routines are easy to forget.
Must be within reach — A pendant on the bench cannot help someone who has fallen in the bathroom.
Must be pressed — Serious falls can leave a person unconscious or too hurt or confused to press anything.
Falls were the leading cause of injury hospitalisations in Australia in 2024 to 2025, accounting for 253,800 hospitalisations, and the leading cause of injury deaths in 2023 to 2024. Australian Institute of Health and Welfare, Falls

How passive fall detection works with nothing to wear
Passive systems such as Vitara CarePilot move the responsibility from the person to the room. A 4D radar sensor is mounted on the ceiling and reads how low-power radio waves reflect off people in the room, which tells it where a person is, how they are moving, and whether their body position suggests a fall. Nothing is worn, nothing is charged, and nothing is pressed.
Because the sensing is radar rather than video, nothing is filmed or listened to, so sensors can cover private spaces like bedrooms and bathrooms. When a fall is detected, the system verifies it and alerts carers and family automatically within seconds. Vitara CarePilot's published fall detection accuracy is 95 to 97 per cent, with verified alerts to keep false alarms to a minimum.
Passive monitoring also catches what a button never can. The system monitors 24/7 and flags unusual inactivity, such as someone not getting up in the morning, so help is raised even when there was no dramatic fall to detect.
Dementia and memory: when wearables stop being realistic
For a person living with dementia or memory loss, a wearable asks for exactly the things the condition takes away. Remembering to put the pendant on, remembering to charge it, understanding what the button is for in a moment of distress, and choosing to press it are all cognitive tasks. Some people also find an unfamiliar device on their wrist or neck distressing and remove it.
Families in this situation often cycle through pendants and watches before concluding that no device that depends on the person will work reliably. Passive room-based monitoring is often the only approach left, because it asks nothing of the person at all. The home is simply protected, whether or not the person remembers the system exists.

When a wearable is still a reasonable choice
Wearables are not the wrong answer for everyone. Room-based sensors protect the home, and only the home. A wearable travels with the person, so for an active older person who walks to the shops, gardens away from the house, drives, or travels regularly, a pendant or watch with GPS covers situations that a home system cannot.
The honest way to decide is to ask where the risk actually is, and whether the person will reliably wear, charge, and use the device. If most of the risk is inside the home, or if memory, stigma, or dexterity makes reliable use unlikely, passive in-home monitoring is the safer foundation. Some families use both: room sensors as the always-on baseline at home, and a wearable for outings.
Choose a wearable when — the person is active outside the home, will wear it consistently, and can manage charging and pressing it.
Choose room sensors when — most time and most risk is at home, or when dementia, refusal, or forgetfulness makes a wearable unreliable.
Consider both when — an otherwise active person has high-risk rooms at home, such as the bathroom, where wearables are usually taken off.
What each approach costs in Australia
Pendant and watch services in Australia typically involve a device purchase or rental plus a monthly monitoring fee, and prices vary widely between providers. The recurring hidden cost is reliability: a service still being paid for while the device sits in a drawer is not providing protection.
Vitara CarePilot is subscription based. The Peace of Mind plan is $69 per month, sensors are $499 each once-off with a minimum of three sensors per home, and each additional room adds $10 per month to the plan. Installation is professional, carried out by licensed electricians, and there is no lock-in contract. Vitara CarePilot is a registered NDIS provider, so NDIS funding may apply for eligible participants. The pricing calculator gives a full estimate for your home, and the cost guide breaks down the numbers in detail.
Common questions
How can falls be detected without a pendant or watch?
Ceiling-mounted radar sensors read the reflections of low-power radio waves to track movement and body position in a room. They detect falls automatically, so there is nothing to wear, charge, or press.
What if the person cannot press a button after a fall?
That is exactly the situation passive monitoring is built for. The sensor detects the fall itself, verifies it, and alerts carers and family within seconds, even if the person is unconscious or unable to call out.
Is room-based fall detection suitable for someone with dementia?
Yes, and it is often the most practical option. It requires nothing from the person, so it keeps working even when a pendant would be forgotten, refused, or removed.
Do room sensors work outside the home?
No. Room-based sensors only cover the rooms they are installed in. For someone who spends a lot of time out and about, a wearable with GPS can be a sensible companion to in-home monitoring.
Does wearable-free fall detection mean cameras instead?
No. Vitara CarePilot uses camera-free 4D radar, so nothing is filmed or recorded. It monitors movement and falls while keeping bedrooms and bathrooms completely private.
