A call button tells you a room. It should tell you a response.

Nurse call, staff duress and resident safety for South African hospitals and private retirement villages — built so that every call leaves a record of who went, from where, and how long it took.

Almost every ward and care home in South Africa already has a call system. The bell rings, a light comes on above a door, somebody goes. What almost none of them have is the second half of that sentence — evidence of what happened next. This page is about closing that gap, and about the two other calls a facility has to answer: the resident who has left the building, and the staff member who needs help and cannot reach a wall.

The three calls a facility has to answer

1. The resident calls

The familiar one. A button at the bed, the bathroom, the pull-cord in the shower. The system knows the room. It does not know who answered, whether they arrived, or how long the resident waited.

2. The resident leaves

Nobody presses anything. A resident with dementia walks out through a door that was propped open in the heat. The first signal is an empty bed at a check — often hours later.

3. The staff member calls

A nurse alone at 02:00, a carer with a distressed resident, a receptionist facing an aggressive visitor. There is no button within reach, and if there were, it would not say where they are.

The first is a call system problem. The second and third are location problems — and that is the part the traditional bell-and-light installation was never built to solve. What has changed is that indoor location is now cheap enough and accurate enough to add to the same system, in the same building, without rewiring it.

Three calls, and only one of them is a call A facility has to answer three different events. The first is what a call system was designed for. The second and third begin with nobody pressing anything, which is why they were never solved by adding more buttons: they are location problems that happen to arrive through the same system.

The three calls named above, before any product is chosen. Two of the three begin with nobody pressing anything — which is why adding more buttons was never going to solve them, and why the table below is about location rather than about call points.

What "with location" actually adds

Question Bell-and-light system Call system with location
Where is the call from?The room the button is wired toThe room — and calls from residents who are not in their room
Who is nearest?Unknown — the call goes to everyoneRouted to the closest available staff member on duty
Did anyone attend?Inferred from the light being cancelled at the wallRecorded on arrival — presence in the room, not a button press
How long did it take?Not recordedCall-to-arrival time per event, reportable by ward, shift and hour
Can staff call for help anywhere?Only where a fixed button existsA wearable duress button that carries the wearer's location with the alarm
Has a resident left?No — nothing was pressedAn exit through a monitored door raises an alarm on its own

This is an upgrade path, not a rip-out. Existing call points, pull cords and door contacts keep working and feed the same event log.

Why this is a compliance conversation, not only a service one

For a hospital or clinic, the norms and standards regulations made under the National Health Act set obligations that a location-aware record speaks to directly. Regulation 17 requires systems "to protect users, health care personnel and property from security threats and risks". Regulation 21 requires a system to monitor and report all adverse events, with a register. Regulation 22 requires waiting times to be monitored. Regulation 20 imports the Occupational Health and Safety Act, whose section 8 places a general duty on every employer to provide a working environment that is safe and without risk to health, as far as is reasonably practicable. None of these say "install location". All of them are easier to evidence when arrival times and presence are recorded rather than remembered.

For a private retirement village or frail care facility, the anchor is different. Under the Older Persons Act, a residential facility may not be operated unless registered, and the operator must report to the Minister within 60 days of financial year end on compliance with the prescribed service standards and the prescribed measures to prevent and combat the abuse of older persons. A call system that records response times, checks completed and who attended turns that annual report from an assertion into a record. We cover the resident-safety half of this in detail on our wander management guide.

The technology, in one honest paragraph

Location comes from small radio tags — a badge, a wristband, or a fixing on a piece of equipment — and fixed reference points in the ceiling or on a wall. The category name for this is a real-time location system (RTLS), or indoor positioning; we avoid leading with the acronym because almost nobody buying one starts there. We use ultra-wideband (UWB), which measures the time a radio pulse takes to travel and so resolves position far more tightly than signal-strength methods like Bluetooth or Wi-Fi. Manufacturer specifications quote accuracy in the tens of centimetres under line-of-sight conditions; in a real building with walls, trolleys and people in the way, the honest planning assumption is room-level and door-level certainty, which is what these use cases actually need. You do not need centimetres to know that a carer entered room 12 at 02:14. You need to be sure it was room 12 and not room 14 — and that is a different, easier, more reliable target.

The system does not need to cover every square metre at the same resolution, and pricing follows that. A single reference point establishes presence in a zone. Two along a corridor track movement through it. Three or more give position within an area. Most facilities need presence in most places and full coverage in a few — which is the difference between a proposal that is affordable and one that is not.

Built for buildings that cannot be rewired

  • No-cable reference points. Where a ceiling cannot be opened — a heritage building, an occupied wing, a village where the disruption is the real cost — battery-powered reference points with a five-year cell and an IP68 housing mount on a wall and report back over a long-range radio link. No conduit, no ceiling voids, no ward closures.
  • Cabled where cabling is easy. New wings and refurbishments take Power-over-Ethernet units on one cable per point, which is cheaper to run and simpler to maintain where the ceiling is already open.
  • It has to survive the cleaners. Wearable tags are specified IP67 or better so they can be wiped down with the disinfectant your infection prevention and control programme already mandates. A tag that cannot be cleaned will not be worn.
  • It has to survive the grid. Reference points, gateways and the server all sit behind backup power, and the system keeps recording locally through an outage rather than losing the shift. In South Africa this is not an optional extra — see our load shedding protection guide.
  • The data stays on your premises. The positioning engine and database run on a server in your own comms room. That is a design decision with a legal purpose, which the next section explains.

Privacy is a design input, not a disclaimer

Under POPIA, "location information" is named in the Act's own definition of personal information. Tracking staff and residents is therefore processing personal information from the first day, and in a health setting it touches the special category that includes health. That is manageable — the Act expressly permits healthcare institutions and facilities to process such information where it is necessary for treatment and care or for the administration of the institution — but only with a confidentiality obligation attached, a defined purpose, a retention limit, and staff who have been told what is collected and why.

It also drives the engineering. Room-level resolution rather than centimetre-level, retention measured in weeks rather than years, and reporting that answers "was this call answered in time" rather than "where was Sister Ndlovu at 14:32" are all choices made at design time. We build to them by default. The full treatment — which lawful basis applies to staff versus residents, what happens when an employee objects, and what a defensible retention policy looks like — is in our POPIA guide to location tracking.

One boundary we hold firmly: this is a location and safety system, not a medical device. Some wearable tags can sense a wearer's pulse or detect that they have not moved, and that is useful as a trigger to send someone to look. It is not clinical monitoring, we do not present it as clinical monitoring, and it does not replace any clinical observation or device your clinicians rely on.

How a project runs

  • 1 · Site survey. We walk the building with you, mark which areas need presence and which need full coverage, identify where cable can and cannot go, and agree what evidence the system has to produce. This is also where the privacy design decisions get made, before anything is bought.
  • 2 · Design and reference cases. You get a layout, a bill of materials, and a written scope — plus comparable deployments to interrogate, such as our retirement village case study. We would rather show you a facility of your shape than hand you a demo kit that proves nothing about your building.
  • 3 · A first area, proven. One ward or one wing goes in and runs live, against the acceptance criteria agreed at survey. If the response-time record is not trustworthy in that area, it will not be trustworthy in twelve.
  • 4 · Phased rollout. The rest follows at the pace your operations and budget allow, on the same server and the same design.
  • 5 · Handover you own. Documentation, API access to your own event data, and training for the people who will run it. Your records are yours.

Hardware is within our quoting scope: we supply the tags, reference points, gateways and server as part of the delivered system, and we quote per project against the survey. On radio compliance, two things are worth keeping separate in South Africa. UWB equipment of this class falls within the licence-exempt schedule of the radio frequency spectrum regulations, so no per-site spectrum licence is needed to operate it. Separately — and regardless of that exemption — the Electronic Communications Act requires radio apparatus supplied and used here to hold ICASA type approval. Make it a written term of supply, of any supplier you deal with. Our hidden costs guide explains why that line item catches so many buyers out.

Weighing this against what you already have? Nurse call vs location systems compares the five options and what each one cannot tell you, and installing in old buildings covers the engineering that decides whether the record is trustworthy.

Looking for something adjacent? Tracking equipment rather than people is covered in hospital equipment tracking — usually the sensible first project, since it proves the same infrastructure and processes no personal information — and in asset tracking. Monitoring temperature in a pharmacy fridge or a vaccine store is environmental monitoring. Managing the building's plant, energy and access as a whole is building management.

FAQ

Nurse call and staff safety — common questions

What is a nurse call system?

A nurse call system is the summoning layer in a ward, clinic or care home: fixed call points at the bed, the bathroom and the pull cord in the shower, wired back to a panel that lights up and sounds when one is pressed. It tells staff that someone in a given room wants help — reliably and cheaply, which is why nearly every facility has one. What it does not do is identify who responded, confirm that they arrived, measure how long the person waited, or notice a call from anybody who is not in a wired room. Those are the gaps a location layer closes.

How does a nurse call system work?

In its traditional form: a resident presses a button or pulls a cord, a circuit closes, a light comes on above the door and at the nurses' station, a tone sounds, and the alert clears when somebody presses reset at the wall. Everything is tied to the room the hardware is wired to. With a location layer added, the same press also routes the call to the nearest available staff member on duty, records arrival when that person is actually present in the room rather than when a light is cancelled, escalates on a timer if nobody acknowledges, and writes a call-to-arrival time for the event.

What does a nurse call system cost in South Africa?

There is no useful single figure, and a supplier who quotes a nurse call system price before walking your building is guessing. Five things drive the number: how many call points and rooms; whether existing wiring and call points can be retained or the system is at end of life; how much of the building needs a location layer and at what resolution, since presence in a zone costs a fraction of full area coverage; whether reference points can be cabled or must be battery-powered because ceilings cannot be opened; and how many wearables staff and residents need. We quote per project against the survey, with hardware included in the scope — our nurse call system price guide sets out the full line-item model and what to make every supplier itemise. The cheapest quote you receive is usually the one that has assumed the least about your building.

Do you supply nurse call systems for care homes as well as hospitals?

Yes, and private retirement villages and their on-site frail care units are a core focus rather than an afterthought. The obligations differ from a hospital's: a residential facility must be registered under the Older Persons Act, and its operator reports annually to the Minister on compliance with prescribed service standards and measures to prevent and combat abuse of older persons. The system design differs too, because a village is cottages, gardens and gates rather than wards and corridors — which is where battery-powered reference points and outdoor boundaries matter far more than they do in a hospital.

Do we have to replace our existing nurse call system?

No, and usually you should not. Existing call points, pull cords, bed leads and door contacts keep working; the location layer is added alongside them and both feed one event log. The upgrade is what happens after the button is pressed — routing the call to the nearest available staff member, recording arrival by presence rather than by someone cancelling a light at the wall, and producing response-time reports. Facilities that are replacing an end-of-life system anyway can do both at once, but that is a budget decision, not a technical requirement.

How accurate is the location, really?

Manufacturer specifications for ultra-wideband quote accuracy in the tens of centimetres under line-of-sight conditions. That figure degrades when walls, trolleys and people sit between the tag and the reference point, so we plan to a more honest target: certainty about which room, which corridor and which door. That is what these use cases need. Knowing a carer entered room 12 at 02:14 — and not room 14 — is both sufficient and reliably achievable; promising centimetres in an occupied ward is not.

Can this be installed in an old building we cannot rewire?

Yes. Battery-powered reference points with a five-year cell and a sealed IP68 housing mount on a wall and report over a long-range radio link to a single gateway, so no conduit is run and no ceiling is opened. It is the normal answer for heritage buildings, occupied wings and retirement villages where the disruption of cabling costs more than the cabling. New wings and refurbishments generally use Power-over-Ethernet units instead, because when the ceiling is already open, one cable per point is cheaper and simpler to maintain.

Is tracking our staff legal under POPIA?

It is lawful if it is done properly, and POPIA sets out what "properly" means. Location information is named in the Act's definition of personal information, so the system processes personal information from day one. You need a lawful basis, a defined purpose, a retention limit, security safeguards, and staff who have been told what is collected and why. A point most employers miss: where processing rests on legitimate interests, a data subject may object, and once they do the Act says processing must stop — so the design, the purpose and the conversation with staff all matter more than the technology. Our POPIA guide works through staff and residents separately.

Does the system keep working during load shedding?

It should, and ours is specified to. Reference points, gateways and the server sit behind backup power, and the system continues recording locally through an outage instead of losing the shift — which matters most because emergencies do not politely coincide with grid availability. Battery-powered reference points are inherently unaffected. This is a specification item we raise at survey rather than an accessory sold afterwards.

Where is the data stored — and who can see it?

On a server in your comms room. The positioning engine and the event database run on your premises, under your access control, which keeps personal information inside the institution and makes the confidentiality obligation POPIA attaches to health information far easier to honour. You get documented API access to your own event data so it can feed your existing reporting, and you are not dependent on us to read your own records.

Can the wristband monitor a resident's vital signs?

Some wearable tags can sense a pulse or detect that the wearer has not moved for a period, and that is genuinely useful — as a trigger to send a person to go and look. We are careful about the claim: this is a location and safety system, not a medical device, and it neither performs nor replaces clinical monitoring. Anything presented as clinical measurement in South Africa falls under medical device regulation, which is a different regime with different obligations. If a facility wants clinical monitoring, that is a conversation with a medical device supplier, not with us.

Does UWB equipment need a spectrum licence in South Africa?

Equipment of this class falls within the licence-exempt schedule of the radio frequency spectrum regulations — the 6–8.5 GHz entries covering this type of device are listed there, so no per-site spectrum licence is needed to operate it. Licence exemption is not the whole compliance story, though, and the two are easy to confuse: under the Electronic Communications Act, radio apparatus supplied and used in South Africa must hold ICASA type approval, and that requirement applies regardless of any spectrum exemption. It is worth writing into the supply agreement rather than assuming it, whoever you buy from.
