How Geofencing Improves Safety for People Living with Dementia
Walking can remain an important part of everyday life for a person living with dementia. Familiar routes, time outdoors and regular community activities may support routine, movement and connection. However, memory changes and disorientation can sometimes make it difficult for a person to recognise where they are, remember the way home or judge potential hazards.
Geofencing adds a digital safety layer around these routines. When used through a GPS-enabled personal alarm or safety watch, it allows a family member or carer to create a virtual boundary around a selected location. If the wearer moves beyond that area, nominated contacts can receive an alert and check whether assistance is needed.
Creation of a Virtual Safe Zone
A geofence is a boundary created on a digital map rather than a physical fence. It may be positioned around a home, retirement community, garden, familiar shopping area or another location that forms part of the person’s usual routine.
A compatible GPS watch or pendant monitors whether the wearer remains within that selected area. It can allow carers to set a perimeter around a chosen address and receive an alert when the wearer enters or leaves it.
These digital boundaries are highly customizable, allowing you to set a minimum radius of 10 metres for small, precise spaces like a house or garden, up to a maximum distance of 2.5 kilometres for wider neighborhood exploration. The boundary can be adjusted to suit the person’s routine rather than applying the same distance to every situation.
Earlier Alerts When a Routine Changes
Without an alert system, a family member may not realise that someone has left home until considerable time has passed. A geofence can provide an earlier indication that the person has moved beyond the expected area, allowing a trusted contact to call, check the GPS position or arrange support.
The person may have taken a different walking route, gone out with someone else or moved outside the zone for a planned reason. Even so, an early notification gives the support network information they can assess instead of relying on guesswork.
Support for Independence Without Constant Physical Supervision
Safety planning for dementia should not automatically mean removing every opportunity for independence. Some people may still enjoy walking in the garden, visiting a nearby location or moving around a familiar community setting. Their abilities, preferences and level of risk should guide the plan.
Geofencing can support this balance by operating quietly in the background. Rather than requiring someone to follow every movement physically, the technology can alert the chosen contacts when a boundary is crossed. This may allow the wearer to continue appropriate activities while giving family members a practical way to respond if the usual pattern changes.
Locating Someone Who Becomes Disoriented
When someone becomes lost, knowing where to begin looking can be difficult. Real-time GPS information can show the wearer’s current or recent position, helping family members, carers or responders narrow the search area.
Compatible watch settings can also provide live and historical location information. This can be particularly useful when a person has moved away from a familiar route or cannot clearly explain where they are.
GPS information is not perfect, however. Buildings, limited satellite visibility, mobile coverage and device settings can affect location accuracy. It should therefore be treated as a useful support tool rather than an absolute guarantee of the wearer’s position.
Alerts Across a Trusted Support Network
Caring responsibilities often sit across several people. A partner may be available at home, while adult children, neighbours, support workers or other carers may assist at different times. An alarm system can be configured so that alerts reach nominated contacts instead of depending on one person alone.
Set the System Up Around the Individual
A geofence works best when it reflects the person’s real habits. A boundary that is too small may create repeated unnecessary alerts, while one that is too wide may not provide enough warning. Families may need to review the person’s usual walking distance, familiar destinations, daily routine and known areas of risk before selecting the zone.
It is also important to involve the person living with dementia as much as possible. Explain the device in language they understand and consider comfort, dignity and willingness to wear it. A watch or lightweight pendant may feel less intrusive than a device that looks unfamiliar or medical.
Finally, check the practical details. The device needs to be worn, charged and connected to an available mobile network. Carers should test the alert process, know how to view the GPS location and understand what to do when a notification arrives.
Final Thoughts
Geofencing cannot remove every risk associated with dementia-related disorientation or walking. It can, however, provide earlier alerts, useful location information and a clearer way for family members and carers to coordinate their response.
The MediAlarm Watch combines geofence alerts with live GPS tracking, an SOS button, two-way communication, and fall detection. These features can be configured around the wearer’s needs and existing care plan.
When choosing a personal alarm for someone living with dementia, consider their usual routine, comfort with the device, mobile coverage, charging needs and who will respond to alerts. MediAlarm can explain the available watch and pendant options and help families arrange a setup that supports both safety and appropriate independence.
