Wandering Detection in Senior Care: Protecting Residents Without Locking the Doors

In a care home or day centre, the most frightening report is one sentence. We cannot find her.

What happens next is much the same anywhere. Staff scatter to check the dining room, the programme room and the toilets, then the entrance and the car park, and if she still does not turn up they start rewinding CCTV. Meanwhile the remaining residents still need watching, so the available staff is halved.

Most of the time she is found within a few minutes. The difficulty is that on some days those few minutes become tens of minutes, and by then she is already outside the building.

Wandering is not an accident. It is a symptom. For a resident living with dementia, the will to walk is natural, and walking itself is good for health. Which is why approaching this problem as "how do we stop them getting out" tends to break things instead.

I. Locking the Door Is Not the Answer

The fastest remedy looks like a physical barrier. Lock the entrance, control the lift, lock the stairwell.

But that approach sacrifices two things at once. The first is the evacuation route. In a fire or a power failure, a locked door becomes a door that traps residents. The more residents with limited mobility a facility has, the greater that risk. The second is the range of daily life. Locking doors one by one for safety keeps shrinking the space a resident can move through. There is a garden but they cannot go out to it, walks disappear, and anxiety and wandering get worse.

There is an opposite direction. Instead of blocking, knowing. If the facility knows which zone someone is in now, which line they crossed, and when they crossed it, it can respond without locking anything. It is a design that keeps both safety and freedom rather than trading one for the other.

II. Zones Are a Translation of the Care Plan

Location based wandering detection is generally designed around three kinds of line.

The first line is outside the facility. The entrance, the back door, the car park, the area in front of the lift. A signal that this line has been crossed takes priority over any other alert. It is usually set to notify immediately.

The second line is hazardous areas inside the facility. The kitchen, the laundry, the plant room, the medicine store, the stairwell. Here the alert condition is not "went out" but "came in". Distinguishing whether a staff member was accompanying reduces unnecessary alerts substantially.

The third line is the permitted range for each individual. This is the heart of it. Applying the same rule to every resident guarantees the system will fail. One resident is fine going out to the garden alone, another needs checking if they leave the floor, another needs a narrower range only at night. It is the work of translating what is already written in the care plan into zone and time rules, and when that translation is done well the system goes quiet.

Dividing zones is closer to operations than to technology. ORBRO's integrated monitoring platform ORBRO OS is structured so that you draw zones on a facility floor plan and attach conditions and actions to each zone, so when care policy changes you edit zones and rules on screen. It is not a matter of rebuilding the structure of the facility.

III. What Happens After the Alert Sounds

Where these systems fail is not detection performance. It is what comes after detection.

Start by deciding where the alert goes. If only the nursing station monitor sounds, the staff member who is away from that station at that moment does not know. In a facility with one or two people on at night it has to reach a phone, and which phone has to change with the shift.

More important is managing false alarms. If the alert sounds thirty times a day, staff turn it off or ignore it. Then the system might as well not exist. The way to reduce alerts is not to lower sensitivity but to combine conditions. Do not fire merely because someone entered the entrance zone; fire when the time spent there exceeds a threshold or they actually go outside, or when no accompanying staff tag is in the same zone at that time.

Search time falls too. When the last confirmed zone and direction of travel appear together, several staff members go to one place rather than dividing the building between them. That difference changes the outcome of the day.

IV. The Problem of Keeping It Worn

This kind of system only works if the device is on the body. And residents often take it off.

Choose the form first. A wristband is light to wear but easy to remove; a pendant type stays on better but is uncomfortable when lying down. Attaching to shoes, a walking frame or a wheelchair avoids touching the person, but if they move without that aid you lose them. The right answer differs by facility, and rather than standardising on one type, facilities usually mix by resident.

Next is operation. If the charging cycle is daily, the system will not last. Whose routine includes putting the device back on in the morning after it was taken off at night also has to be settled in advance. Water resistance matters more than expected, because devices really do die during washing or showering.

If an accelerometer is included, one more thing becomes possible. When a device stays completely still in one place for a long time, non wear can be inferred. Mistaking a device that has been taken off for the person and displaying them as safe is the most dangerous failure mode of this system, so it is worth confirming before deployment whether non wear is flagged separately.

V. Why the Record Matters

Reviewing wandering detection, it is easy to look only at real time alerts, but in actual operation the side that keeps paying out longest is the record.

It is not simply a log of who was where. If a resident has started moving around at night more often over the past month, that can be a signal of a change in condition and grounds for revisiting the care plan or seeking medical review. When there has been a fall, being able to replay the movement immediately before lets you explain to the family what happened and where. Being able to explain and not being able to explain sit in completely different places in terms of trust.

One thing should be made explicit here. What this system sees is position, not video. In shared areas such as living rooms and corridors, video functions like fall detection are sometimes added as a supplement, but designs that put cameras into living spaces are usually refused on site first. And the measurement target is not staff work performance. Staff tags are used to judge accompaniment and thereby cut unnecessary alerts. Fail to make that line clear at the start of deployment and the floor turns its back first.

Five Things to Check When Reviewing

1. Within how many seconds does it report an exit from the facility. And which device, belonging to whom, does that alert reach.
2. Can rules differ per resident. A product that only supports one blanket rule gets switched off before long, killed by false alarms.
3. Are time based rules supported. The permitted range by day and by night cannot be the same.
4. Does it distinguish non wear. A system that counts a device left on a table as a person is telling you it is safe when it is lying.
5. How do you get the record out. Retention period, how it is queried, and whether it comes in a form you can use to explain things to a family.

Closing

Think of wandering detection as a surveillance device and deployment will almost certainly meet resistance. Yet the change this system actually produces is closer to the opposite. If you can know where someone is, the facility can leave more doors open. Going out to the garden is fine, and walks can go back into the programme.

Safety and freedom are usually treated as inversely related, but the moment you know position, that trade off loosens. Because you can protect without locking.

ORBRO builds everything from wearable location tags through the edge server placed on site, up to ORBRO OS, the monitoring platform where zones and alerts are designed on a floor plan. Facility scale, floor composition, and how you currently detect wandering is enough for us to begin.
