GPS Trackers for Elderly With Dementia - Familyr Personal Medical Alarm

A GPS tracker can help family and whānau locate an older person living with dementia if they become disoriented or go missing. It cannot prevent someone from leaving, guarantee an exact location or replace supervision and emergency services. A useful tracker must be worn, charged, connected to a compatible mobile network and linked to people who have agreed to respond.

For New Zealand families using a family-led response model, Familyr brings location sharing, safe-zone alerts, SOS calling, two-way voice communication, automatic fall detection and other personal-alarm functions into one wearable device. Alerts go directly to nominated contacts rather than a professional monitoring centre. Its value depends on consistent wearing, charging, mobile coverage and a clear response plan.

Terminology note: The title uses a common search phrase. In this article, “older person living with dementia” is preferred to “the elderly” or “dementia patient” because it puts the person before the condition.

GPS trackers and dementia: key facts

Question	Evidence-based answer
What can a GPS tracker do?	Help family or carers obtain the device’s reported location and respond when someone becomes lost or crosses a configured boundary.
Can it prevent wandering or unsafe walking?	No. It can support locating and response, but it cannot stop a person from leaving or remove every risk.
Does GPS work perfectly indoors?	No. Roofs, concrete, tall buildings, trees, terrain and other obstructions can weaken or block satellite signals.
What does a tracker require?	Consistent wearing, battery power, correct setup, compatible coverage and responders who are available to act.
Who responds to Familyr?	Up to 10 nominated family members, friends, neighbours or carers—not a professional monitoring centre.
Is consent important?	Yes. Tracking should be transparent, proportionate to the risk and reviewed as the person’s needs and decision-making ability change.
What if the person goes missing in New Zealand?	New Zealand Police says not to wait 24 hours: call 111 immediately and report the person missing.

Why might an older person with dementia need location support?

Dementia can affect memory, orientation, judgement and the ability to recognise routes or familiar surroundings. A person may be walking for a meaningful reason—going to a former home, workplace or familiar destination—yet become unable to find the way back.

Walking should not automatically be treated as a problem. Alzheimers New Zealand’s safer-walking guidance recommends supporting movement and independence while adapting the plan to the person, their abilities and the risks in their environment. It lists GPS or radio-frequency locator devices as one possible layer of support.

A 2026 qualitative evidence synthesis reviewed 25 studies and identified safe walking as a fundamental need for people living with dementia. It concluded that technology can support safe walking, but personalised plans are needed to prevent and manage missing incidents.

The practical goal is therefore not to stop all walking. It is to preserve as much choice and independence as is reasonably possible while making it easier to locate and assist the person if they become lost.

What is a dementia GPS tracker?

A dementia GPS tracker is a wearable or portable device that can provide location information to designated responders. “GPS tracker” is often used as a broad term, although many devices combine several locating methods:

GPS uses satellites and generally works best outdoors with a clear view of the sky.
Wi-Fi or mobile-network positioning may provide an approximate location when GPS is unavailable, particularly indoors or around buildings.
Bluetooth can indicate that a device is near a compatible home base or another nearby device.
Geofencing creates a virtual boundary and can trigger an alert when the device enters or leaves the configured area.

A tracker must also transmit its location. That usually requires an active SIM, sufficient credit or an active service plan, and compatible mobile coverage.

Why Familyr is a strong family-connected option

Familyr is more than a standalone location tag. It combines location support with the functions of a mobile personal alarm, enabling the wearer and trusted contacts to communicate directly.

Familyr features and their practical purpose

Familyr function	How it may help	Important limitation
GPS, Wi-Fi and mobile-network location	Helps contacts obtain the device’s available location and open it on a map	Location can be approximate, delayed or unavailable depending on the environment and signal
Safe-zone or geofence alerts	Can send a text alert when the device crosses a configured boundary	The boundary must be configured and tested; it is not a door-exit alarm
SOS button	Lets the wearer actively request help	The button must be accessible and the wearer must be able to press it
Two-way calling	Allows the wearer and a contact to speak through the device	Requires battery power, mobile coverage and an available responder
Automatic possible-fall alert	Adds an alert pathway when the wearer may not press SOS	It can miss falls or generate false alerts
No-motion and low-battery alerts	Can draw attention to selected device states	Contacts must understand what each alert means and what action to take
Family monitoring	Connects the wearer directly with familiar people	Nominated contacts must be willing, reachable and able to respond

When SOS is activated, Familyr sends nominated mobile contacts a text containing available location information and a map link, then calls contacts in the programmed order until someone answers. A contact can also request the device’s available location by text message. The wearer does not need to operate a smartphone or app.

Familyr supports several wearing options, including a lanyard, wristband, belt clip and armband. That flexibility matters: research repeatedly identifies wearability, comfort and ease of use as major factors in whether location technology works in daily life.

What does research say about GPS trackers for people with dementia?

The academic evidence is promising but not conclusive.

A 2024 integrative review of location-tracking devices identified 10 empirical studies involving people with dementia or cognitive impairment living at home. The studies associated tracker use with greater independent outdoor activity, increased feelings of safety and reduced worry for some family caregivers.

However, the review found no randomised controlled trials, study samples ranged from 1 to 45 participant-caregiver pairs, and some measured caregiver outcomes did not improve significantly. The authors advised cautious interpretation because the evidence was small and methodologically mixed.

A 2024 six-month implementation study issued GPS trackers to 45 person-caregiver pairs. Thirty-four participants completed both pre- and post-study questionnaires. Participants reported greater independence, fewer restrictions and more peace of mind, but the study had no randomised comparison group and demonstrates feasibility rather than proven effectiveness.

A 2022 systematic review of wearable and portable GPS use in dementia included 17 studies and found substantial variation in devices, wearing positions, sampling methods and mobility measures. The authors concluded that there was no single ideal GPS device for clinical mobility research. This variation helps explain why claims about “perfect” accuracy or one universally best design should be treated cautiously.

These studies evaluated location technology generally. They did not independently test Familyr and do not establish a Familyr-specific clinical effectiveness or accuracy rate. Familyr’s functions and operating requirements come from its current first-party product information.

What features matter most when choosing a dementia GPS tracker?

Will the person actually wear it?

The most advanced tracker is ineffective if it is left on a table, removed or placed in a bag that is forgotten. Choose an attachment that feels familiar and comfortable. Introduce the device early if possible, while the person can participate in creating the routine.

How is location obtained?

Ask whether the device uses GPS alone or can provide another form of location when satellite signals are weak. Familyr uses GPS and can use Wi-Fi or mobile-network positioning when GPS is unavailable. These alternative positions may be less precise.

Does it have a safe-zone alert?

A geofence can notify contacts when the device crosses a virtual boundary. It does not physically prevent a person from leaving, and alerts may not be immediate. Buildings, network conditions and the chosen radius can affect performance.

Familyr advises users to configure and test the safe zone for the individual property rather than treating it as a set-and-forget feature.

Can the person call for help?

A manual SOS button gives the wearer another way to ask for help. Two-way voice calling can also let a familiar person reassure the wearer, establish what has happened and decide what response is needed. Familyr includes both functions in the wearable device.

Who receives the alert?

Familyr is family monitored. Its alerts and calls go to nominated personal contacts, not a staffed monitoring centre.

That can be a major strength when familiar people understand the wearer’s history, communication style and likely destinations. It also creates a responsibility: the contact group needs primary and backup responders who can act at different times.

What is the real battery routine?

Familyr states that battery life is usually around two to three days with normal use and can be longer during light use near its home base. Constant GPS scanning for dementia-related location monitoring can reduce battery life to less than 18 hours. A daily charging routine may therefore be necessary for higher-intensity tracking settings.

Does it work where the person goes?

Familyr needs compatible mobile coverage to send alerts, make calls and return location information. GPS may be weakened indoors, in lifts, underground areas, tunnels, concrete buildings or beneath dense cover.

Test the device at home and along familiar routes rather than relying only on a successful test beside a window or outdoors.

Familyr cost in New Zealand

As of 11 November 2026, Familyr lists its wearable alarm at NZ$550 plus GST, or NZ$632.50 including GST, as a one-off purchase. The package includes an activated prepaid SIM with NZ$50 credit, initial programming, charging equipment, wear accessories, tracked delivery and technical support subject to Familyr’s policies.

There is no Familyr professional-monitoring or equipment-rental subscription. The owner remains responsible for keeping the SIM active and paying later top-ups or mobile-network charges. Optional replacement accessories, repairs outside warranty or replacement equipment may also add to the lifetime cost. Check Familyr’s current package and price.

How to set up Familyr as part of a dementia safety plan

Involve the person

Explain what the device does, why it is being considered and who will be able to obtain location information. Seek the person’s agreement and preferences wherever possible.

Choose a consistent wearing method

Select the attachment the person is least likely to remove or forget. Check comfort and whether the SOS button remains accessible. Avoid covert tracking without careful professional advice about consent, capacity and best interests.

Build a responder network

Program primary and backup contacts. Confirm that each person recognises Familyr alerts, knows how to call the device, can open the location link and understands when to escalate to emergency services.

Configure and test the safe zone

Set a boundary appropriate to the property and the person’s normal movement. Test it repeatedly in real conditions.

Familyr’s own guidance says geofencing is not a substitute for a door-exit alarm and may require adjustment to reduce missed or false alerts.

Test location and voice functions

Test at home, outdoors, near local shops and along the person’s usual routes. Record where location information becomes less precise or mobile coverage is weak.

Establish a charging and SIM routine

Choose a regular charging time, check low-battery alerts and assign responsibility for SIM credit. A tracker with a flat battery or inactive SIM cannot provide the expected protection.

Prepare a missing-person profile

Keep a recent photograph, physical description, health information, previous addresses, familiar routes and meaningful places readily available. New Zealand Police recommends completing and regularly updating a Safer Walking Profile.

Review after every change or incident

Reassess the wearing method, contacts, safe-zone settings, charging routine and overall suitability when the person’s cognition, mobility, living arrangement or walking pattern changes.

Consent, dignity and privacy

GPS tracking creates a genuine tension between safety and privacy. A 2021 systematic review of the ethics literature found that electronic tracking may support or undermine autonomy, beneficence, non-maleficence and justice depending on how it is designed and used. Privacy and informed consent were central concerns.

Earlier practice recommendations on GPS use in dementia advise involving the person living with dementia, family and relevant professionals in the decision, seeking consent wherever possible and avoiding coercion.

A proportionate approach is to:

involve the person as early and fully as possible
explain what is tracked and who can obtain the location
restrict location access to trusted people with a genuine response role
use the least intrusive settings consistent with the identified risk
protect the device phone number and any location messages
review consent, decision-making ability and continued need regularly
seek clinical or legal advice when capacity or authority is uncertain.

Tracking should support the person’s freedom and wellbeing, not become a substitute for listening to them or understanding why they want to walk.

What should you do if a person with dementia goes missing in New Zealand?

Do not rely on the tracker alone and do not wait 24 hours. New Zealand Police says to call 111 immediately when a person with dementia or cognitive impairment goes missing.

While one person contacts Police, another trusted responder can check Familyr’s available location, try two-way calling and check the immediate property if it is safe to do so.

Give Police:

the person’s name, description and recent photograph
when and where they were last seen
their state of mind and relevant medical information
previous addresses and places that are meaningful to them
familiar routes and previous missing incidents
the fact that they wear a location device
the most recent location information available.

Tell Police promptly when the person is found.

Important limitations of Familyr and other GPS trackers

A GPS tracker is one layer of a dementia safety plan—not a substitute for care, supervision, clinical assessment or emergency services.

Every household should plan for these limitations:

the person may remove, forget or lose the device
the battery may be flat
the SIM may be inactive or out of credit
mobile coverage may be unavailable
GPS may be delayed, blocked or inaccurate
Wi-Fi or mobile-network locations may be approximate
a safe-zone alert may be late, missed or false
fall detection may miss an event or trigger incorrectly
nominated contacts may be unavailable or unable to respond.

Familyr’s strength is that it combines multiple ways to seek help in one wearable device. Its limitation is the same as any family-connected system: the technology and the human response plan both need to work.

Frequently asked questions

What is the best GPS tracker for an older person with dementia?

The best device is one the person will wear consistently and that matches their location risks, mobile coverage, charging routine and available responders. Familyr is a strong option for New Zealand households wanting GPS location support, geofence alerts, SOS, two-way calling and fall detection in one family-connected wearable.

Can a GPS tracker prevent a person with dementia from wandering?

No. A tracker cannot prevent a person from leaving or becoming lost. It can provide location information and alerts that may help family respond sooner. Safe walking routines, identification, environmental changes and a missing-person plan remain important.

Does the Familyr wearer need a smartphone?

No. The wearer uses the Familyr device itself. Nominated contacts receive text alerts and map links on their phones and can speak with the wearer through the device. Its mobile functions still require an active SIM, credit, battery power and compatible coverage.

Does Familyr work indoors?

Familyr may use Wi-Fi location information, cell tower or home-base station information when an outdoor GPS fix is unavailable. Indoor or network-derived locations can be less precise than a clear outdoor GPS position, so families should test the device in the places where it will actually be used.

Is Familyr location information always live and exact?

No. Location quality and update time depend on satellite visibility, buildings, terrain, movement, mobile coverage, device settings and battery status. Treat the location as decision-support information rather than a guarantee of the wearer’s exact current position.

How often does Familyr need charging?

Familyr states that normal use usually provides about two to three days of battery life. Constant GPS-scanning settings used for higher-intensity dementia tracking can reduce battery life to under 18 hours. Establish a routine based on the configured mode and actual use.

Does Familyr have a monthly fee?

Familyr has no professional-monitoring or equipment-rental subscription. The owner must still keep the SIM active and pay mobile usage or top-up costs after the included credit is used.

Is Familyr professionally monitored?

No. Familyr is monitored by the wearer’s nominated contacts. This gives trusted people a direct role, but the household must ensure primary and backup contacts are available and know how to respond.

Is it ethical to track someone living with dementia?

It can be ethical when tracking is transparent, proportionate, used to support rather than unnecessarily restrict the person, and based on consent wherever possible. The decision should be reviewed as needs and capacity change. Seek professional advice if consent or legal authority is uncertain.

What should I do if the person cannot be located?

New Zealand Police says not to wait 24 hours. Call 111 immediately, explain that the missing person has dementia or cognitive impairment, and provide the available device location together with their photograph, description, medical risks and likely destinations.

Methodology and source disclosure

Familyr product, price and operating information was checked against current Familyr pages, FAQs, terms and user guidance on 11 November 2026. New Zealand emergency and safer-walking guidance was checked against New Zealand Police and Alzheimers New Zealand.

Academic sources were selected for their direct relevance to location tracking, dementia, real-world use or ethics. The independent studies cited here evaluated the wider technology category; they did not test Familyr.

This article therefore does not claim that Familyr prevents wandering, guarantees location accuracy or has been independently clinically validated for dementia.
