Around 900,000 people in the UK are living with dementia, and that number is expected to exceed 1 million by 2030. It's a condition that touches almost every family eventually — and one of the most frightening aspects for carers is wandering.
Around 60% of people with dementia will wander at some point. They may leave the house confused, disoriented, and at serious risk — often without a phone, without ID, and without any way to ask for help or tell someone where they are. In winter, the consequences can be devastating.
The good news is that technology has come a long way. GPS trackers, smart home sensors, and monitoring systems now give families a practical way to keep their loved one safe — whilst preserving as much dignity and independence as possible. This isn't about surveillance. It's about peace of mind.
We've spent over three months testing and researching the best dementia tracking devices available in the UK. In this guide, we'll walk you through the different types of technology, review the top five devices, and help you choose the right option for your family.
For most families, we recommend the Oysta Pearl+ — a purpose-built GPS tracker with fall detection, geofencing, and a 24/7 UK response centre. It's specifically designed for people with dementia and is used by police forces across the UK. If your mum or dad is at risk of wandering, this is the device we'd choose for our own family.
Why tracking matters in dementia care
Wandering is one of the most common and dangerous behaviours associated with dementia. It's not a choice — it's a symptom of the condition. Someone with dementia may believe they need to go to work, pick up the children from school, or visit a place from decades ago. They're following a logic that makes perfect sense to them, even if it puts them at risk.
Here's what the numbers tell us:
- 60% of people with dementia will wander at some point during their illness
- Wandering can happen at any time — day or night, in any weather
- People with dementia may not be able to ask for help or explain where they live
- If not found within 24 hours, up to half of wanderers will suffer serious injury or worse
UK police forces use the Herbert Protocol — a scheme where carers pre-register details about a person with dementia (photo, description, favourite places, daily routine) so that if they go missing, the police have the information they need immediately. It's a sensible precaution, and we'd encourage every family to complete one. But prevention is always better than a search.
This is where technology comes in. A GPS tracker can alert you the moment your mum or dad leaves the house — or leaves a defined safe zone. Smart home sensors can tell you if something is wrong before it becomes a crisis: a door opening at 3am, the cooker left on, or no movement detected for hours.
It's important to say this clearly: tracking technology for someone with dementia is not about surveillance. It's about safety and peace of mind — for the person with dementia and for their family. Used well, it can actually support independence, allowing someone to stay in their own home for longer rather than moving into residential care.
Types of dementia tracking devices
There's no single device that suits every situation. The right choice depends on your parent's stage of dementia, their daily habits, and your budget. Here are the main types of technology available:
Top 5 UK dementia trackers reviewed
We've tested and researched the most popular dementia tracking devices available in the UK. Here are our top five picks, each suited to a different situation and budget.
1. Oysta Pearl+ — Best Overall
The Oysta Pearl+ is a GPS pendant designed specifically for vulnerable adults. It combines real-time GPS tracking with automatic fall detection, geofencing alerts, two-way voice communication, and access to Oysta's 24/7 UK-based response centre. When the wearer presses the SOS button or a fall is detected, the response centre can speak to them through the device, contact family members, or dispatch emergency services.
- Purpose-built for vulnerable adults
- Used by UK police forces for locating missing people
- Automatic fall detection
- Geofencing with instant alerts
- SOS button with two-way voice
- Waterproof (IPX7)
- 24/7 UK response centre included
- Monthly subscription cost
- Pendant needs charging every 2–3 days
- Requires mobile signal to transmit location
2. AngelSense GPS Tracker
AngelSense offers the most detailed location tracking of any device we tested. Originally designed for children with autism, it's now widely used for adults with dementia. Features include detailed location history, route replay, voice monitoring (briefly listen in to check the person is safe), guard mode for real-time step-by-step tracking, and a non-removable strap option so the wearer can't take it off.
- Very detailed location tracking and history
- Voice monitoring feature for safety checks
- Complete route history and replay
- Designed for vulnerable adults
- Non-removable strap option available
- Geofencing with instant alerts
- More expensive than alternatives
- Requires smartphone app to manage

3. Buddi GPS Alarm
Buddi is a UK-designed GPS tracker worn as a wristband — making it feel more like a watch than a medical device. It offers two-way voice calls, automatic fall detection, geofencing, and an SOS button. Several local authorities across the UK fund Buddi devices through their telecare programmes, so it's worth checking whether your council offers subsidised access.
- Wristband form factor (less stigma than a pendant)
- Two-way voice communication
- Automatic fall detection
- Some council funding available
- UK-designed and supported
- Needs charging daily
- Wristband can be removed by the wearer
- Smaller company than some competitors
4. Canary Care Activity Monitor
Canary Care takes a completely different approach. Instead of tracking a person with GPS, it uses passive motion sensors placed around the home to monitor daily routines. Sensors can detect movement in rooms, fridge door openings, toilet use, and more. Over time, the system learns what's normal and sends alerts when patterns change — for example, if your mum hasn't left the bedroom by 11am, or the fridge hasn't been opened all day.
- No wearable to remember or charge
- Detects early changes in routine
- Simple setup — sensors just stick in place
- Affordable monthly cost
- Respects dignity — completely invisible monitoring
- No GPS — home monitoring only
- Won't help with outdoor wandering
- May not suit all home layouts
- Requires broadband internet
5. Samsung SmartThings Door Sensor
The Samsung SmartThings door sensor is a budget-friendly option that alerts you via the SmartThings app whenever a door or window is opened. You can set up automations — for instance, only receive alerts when the front door opens between 10pm and 7am. It's not a dementia-specific device, but for families on a tight budget or those wanting a simple first step, it does the job surprisingly well.
- Very affordable — around £20
- Easy to install (peel and stick)
- Instant push notifications
- Works with other SmartThings devices
- No monthly subscription required
- No GPS tracking at all
- Requires a smartphone and WiFi
- Basic functionality only

Smart home sensors for dementia
GPS trackers are essential for wandering outdoors, but inside the home, smart sensors can create a safety net that catches problems before they become emergencies. Here's what's available and how it all fits together:
Door and window sensors
These are the simplest and most affordable smart home sensors. A small magnetic sensor on the door frame detects when the door opens, and sends an alert to your phone. The real power is in scheduling — you can set them to only alert you at unusual times, such as between 10pm and 7am. That way you'll know immediately if your mum opens the front door at 2am, but you won't be pestered every time she pops into the garden during the day.
Motion sensors
Passive infrared motion sensors can be placed in key rooms — the kitchen, living room, bathroom, hallway. They track general movement patterns throughout the day. If your dad usually makes tea by 9am and the kitchen sensor hasn't triggered by 11am, you'll get an alert. Over time, they build a detailed picture of daily routine that can reveal gradual changes you might not notice during a weekly visit.
Bed sensors
A pressure pad placed under the mattress that detects when someone gets into or out of bed. Particularly useful for night-time wandering — you can be alerted the moment your parent gets up at 3am, giving you time to check in before they leave the house. Some bed sensors also track sleep quality, which can be a useful indicator of overall wellbeing.
Flood sensors
A small sensor placed beside the bath, sink, or washing machine that detects water on the floor. People with dementia sometimes leave taps running and forget about them. A flood sensor won't prevent this, but it will alert you quickly so you can call a neighbour or pop round before the ceiling comes through.
Cooker shut-off devices
Products like the StoveGuard or Stove Hob Guard automatically turn off the hob after a set period — or if smoke or excessive heat is detected. Kitchen fires are a real risk for people with dementia, and these devices provide an important layer of protection. Some models work with gas hobs as well as electric.
Medication reminders
Automatic pill dispensers with alarms and locked compartments ensure the right medication is available at the right time — and alert you if a dose is missed. The Pivotell range is widely used in the UK and can be set up for multiple daily doses. Some models connect to a monitoring service that will follow up if medication isn't taken.
Building a safety net
The real power of these sensors isn't in any single device — it's in how they work together. A door sensor tells you someone has left the house. A motion sensor tells you they haven't moved all morning. A bed sensor tells you they've been getting up repeatedly at night. A GPS tracker tells you where they are right now. Individually, each device fills one gap. Together, they create a comprehensive picture of wellbeing and safety that can help your parent stay in their own home for longer.
What to look for when buying
Choosing the right tracking device can feel overwhelming. Here are the seven most important things to consider:
-
Battery life
How often does the device need charging? GPS pendants typically last 1–3 days, wristbands 1–2 days. A device that needs daily charging means building it into the daily routine — can your parent manage that, or will you need to visit? Door sensors and activity monitors usually run on coin cell batteries that last 1–2 years.
-
Geofencing
Can you set a safe zone around the home (or any other location) and get an alert the moment they leave it? This is one of the most important features for dementia care. Check how easy it is to set up and adjust — and whether you can have multiple geofences for different locations.
-
SOS button
Is there a simple, clearly marked button the person can press if they feel lost or scared? Even in the later stages of dementia, many people can still press a big button when they need help. The simpler the better — one button, one action.
-
Waterproof rating
Will the device survive a shower, a bath, or getting caught in the rain? Look for an IPX7 rating at minimum. People with dementia may forget to remove a wearable before bathing, so waterproofing isn't optional — it's essential.
-
Comfort and stigma
Will they actually wear it? This is the most practical question of all. A pendant that looks clinical may be refused. A wristband that feels like a watch may be accepted happily. Some people prefer a clip-on device attached to clothing. Consider what your parent would be most comfortable with — and what they're least likely to remove.
-
Response service
Does the device connect to a 24/7 monitoring centre, or does it just send alerts to your phone? A monitoring centre means someone is always available to respond — even at 3am, even when you're on holiday. This is a significant advantage but does add to the monthly cost.
-
Coverage
Does the tracker work indoors? In rural areas? GPS needs a clear view of the sky, so accuracy drops indoors and in built-up urban areas. Good devices use WiFi and mobile cell triangulation as backup. If your parent lives in a rural area, check the mobile coverage map for the specific network the device uses.
Carer support & resources
Caring for someone with dementia is physically and emotionally exhausting. Technology can help with safety, but you also need support for yourself. Here are the key resources available in the UK:
- Alzheimer's Society: Free support line on 0333 150 3456 (open seven days a week). They offer information, advice, and emotional support for anyone affected by dementia — including carers. Their website also has a brilliant online community called Talking Point.
- Dementia UK: Home of the Admiral Nurses — specialist dementia nurses who provide free, expert support to families. Their helpline is available on 0800 888 6678 and they also offer virtual clinics.
- Local council telecare: Your local authority may fund GPS tracking devices, personal alarms, or smart home sensors through a social care needs assessment. Contact Adult Social Services directly, or ask your parent's GP for a referral. Some councils provide Buddi or similar devices at reduced cost or free of charge.
- Carers UK: The UK's largest carers charity. They offer a helpline (0808 808 7777), a carers' rights guide, and information about financial support you may be entitled to — including Carer's Allowance and council tax discounts.
- Herbert Protocol: Register your family member's details with your local police force in advance. If they go missing, the police will already have their photo, description, medication details, and a list of places they might go. Ask at your local police station or download the form from your force's website.
- Respite care: Don't forget to look after yourself. Respite care — either at home or in a care home — gives you a break while your loved one is looked after by professionals. Your local council can arrange this, and it may be partially or fully funded depending on your circumstances.
If you're feeling overwhelmed, please reach out. The Alzheimer's Society and Dementia UK helplines are staffed by people who genuinely understand what you're going through. You don't have to manage this alone.
Frequently asked questions
Yes, in most cases. Under the Mental Capacity Act 2005, if someone lacks the capacity to consent to a particular decision, that decision can be made on their behalf in their best interests. GPS tracking to keep someone with dementia safe is generally considered a proportionate best-interests decision — especially when the alternative is residential care or the risk of wandering and coming to harm. If you're unsure, speak to their GP or a social worker, who can help you make and document a best-interests decision.
This is the biggest practical challenge with wearable trackers. The key is choosing a device they're comfortable with. A wristband that looks like a watch is often accepted more readily than a pendant. AngelSense offers a non-removable strap option, which is particularly useful for people who persistently remove devices. Some families sew a small GPS tracker into a coat lining or attach one to shoes. Activity monitors like Canary Care avoid the problem entirely — the sensors are placed around the home, not on the person.
It varies significantly by device type. GPS pendants like the Oysta Pearl+ typically last 1–3 days between charges. GPS wristbands like the Buddi need charging roughly once a day. Door and window sensors run on small coin cell batteries that last 1–2 years with no intervention. Activity monitors like Canary Care are usually mains-powered, so battery life isn't a concern. When choosing a GPS tracker, think about whether your parent (or someone who visits regularly) can manage a charging routine.
The NHS doesn't directly fund GPS trackers, but your local council may provide subsidised or free telecare equipment after a social care needs assessment. Some councils loan GPS devices like the Buddi at no charge, while others offer a reduced rate. The process starts with a referral — ask your parent's GP, or contact your local Adult Social Services team directly. Separately, Attendance Allowance (a non-means-tested benefit for people over State Pension age who need help) can be used to pay for tracking devices and other care technology.
GPS is less accurate indoors because the satellite signal is weakened by walls and ceilings. Most dedicated dementia trackers compensate for this by using WiFi positioning and mobile cell triangulation as backup. Outdoors, you can expect accuracy of 5–10 metres. Indoors, this may drop to 20–50 metres — enough to identify which building someone is in, but not which room. For indoor monitoring, activity sensors and door sensors are far more effective than GPS and work perfectly regardless of signal strength.
