NGOs – The Unique Risks They Face and How Vismo Can Help
NGOs face a constantly shifting risk landscape, from disease outbreaks to political instability. Vismo, a GISF partner, helps protect staff worldwide.
Every employer has a legal duty of care to protect staff from foreseeable harm. For many organisations, the moment that duty is tested is a sudden and frightening one: an aggressive customer, a medical emergency in the field, or a lone worker who stops responding. In those moments, seconds matter. A duress button exists for exactly that moment: a fast, discreet way for someone in trouble to raise the alarm and get help on its way.
This guide explains what a duress button is, how a duress alarm system works, the difference between a duress button and a panic button, the main types available, and what to look for when choosing a solution for your workforce.
What is a duress button?
A duress button is a device, or a feature within a safety app, that allows a person to send an immediate and often silent alert when they feel threatened or are in danger. Pressing it signals to colleagues, a security team or a monitoring centre that the person needs urgent help, without drawing attention from whoever is causing the threat.
The word duress means being under pressure or coercion. That distinction matters. A duress alarm is designed to be triggered discreetly, in situations where openly calling for help could put the person at greater risk, for example a lone worker facing an aggressive individual, a receptionist confronted at a desk, or a member of staff being forced to act against their will.
At its simplest, a duress button does three things: it captures that a person is in trouble, it tells the right people where that person is, and it starts a response.
Duress button vs panic button: what is the difference?
This is the most common question we hear, and the honest answer is that the two terms overlap. Many providers, and many buyers, use duress button and panic button to mean the same thing. But there is a meaningful difference worth understanding.
A duress button typically implies a covert, silent alert raised under coercion, where the emphasis is on not alerting the aggressor. A panic button is often used more broadly for any emergency alert, and can be either silent or audible.
-
Duress: “I am in danger and I cannot let the person near me know I am calling for help.” Silent by design.
-
Panic: “I need emergency help now.” May be silent to avoid escalation, or audible to deter a threat and attract attention.
The right behaviour depends on the situation, which is why the best solutions let you configure whether an alert is silent or triggers an audible response. If you are evaluating options, do not get hung up on the label. Focus on what actually happens after the button is pressed.
How does a duress alarm system work?
A duress button is one part of a wider duress alarm system. The button is the trigger. The value is in the chain of events it sets off. A well-designed system follows four steps:
-
Trigger: The user activates the duress button, whether that is a physical press, a wearable device, or a discreet action within a mobile app.
-
Alert with location: An alert is sent instantly to the designated recipients, along with the user's real-time location so responders know exactly where to go.
-
Response: The right people are mobilised: a colleague, an in-house security team, a professional Alarm Receiving Centre, or the emergency services.
-
Escalation and audit: If the first responder does not acknowledge the alert, it escalates automatically to the next person. Every step is logged, giving you an audit trail for compliance and post-incident review.
The critical point: an alert with no location, or no guaranteed response behind it, is not protection. It is a false sense of security. When comparing solutions, scrutinise the response and escalation as hard as you scrutinise the button.
What makes up a duress alarm system?
A single button is not a system. A complete duress button system is the combination of parts that turns one press into a dependable response, and it is worth understanding those parts before you buy, because a weakness in any one of them undermines the rest.
The trigger
The device or feature the user activates: a fixed button, a wireless duress button, a wearable, or a discreet action inside a mobile app. This is the part most people picture, but on its own it does nothing.
The connection
The link that carries the alert from the trigger to the people who can help, whether that is a building network, a mobile data connection, or a satellite link where there is no coverage. A duress alarm system is only as reliable as the connection behind it.
The response
The people and process that receive the alert and act on it: an in-house security team, designated colleagues, or a professional Alarm Receiving Centre providing round-the-clock cover. Without a defined responder, an alert simply lands nowhere.
The audit trail
A record of every alert, who received it, how it was handled and how long it took. This is what lets you evidence your duty of care, review incidents honestly, and improve your response over time.
Types of duress buttons
Duress buttons come in four broad forms, and the right one depends on where and how your people work.
Fixed and hard-wired duress buttons
Physical buttons installed under a desk or on a wall, common at reception desks, bank counters and healthcare settings. They are reliable for static locations but useless the moment someone moves away from the fixed point.
Wireless duress buttons
A physical button that communicates wirelessly, giving more flexibility within a building or site. Better than fixed buttons for staff who move around, but still tied to a defined area and dependent on additional hardware.
Wearable duress devices
Pendants, fobs or badges carried on the person. Useful in healthcare and social care, but they are another device to distribute, charge, maintain and replace, and they typically offer limited location accuracy beyond a single site.
App-based (mobile) duress and panic buttons
A duress and panic capability built into a smartphone app the employee already carries, such as the Vismo Locate & Protect App. This is the modern approach for mobile, lone, field-based and travelling workers. There is no extra hardware to buy or manage, it works wherever there is a mobile signal, and it can send the user's precise, real-time GPS location with every alert. It also enables features fixed hardware cannot offer, such as location-aware alerting and two-way communication.
How is a duress alarm triggered?
A duress button does not have to mean a single physical press. Modern duress alarm systems offer several ways to raise an alert, so the method can match the situation and the person's ability to act.
Manual activation
The classic press: a hardware button, or a clearly marked control within an app, that the user activates deliberately when they need help.
Silent or covert activation
A discreet trigger that raises the alarm without any visible or audible sign, for situations where letting an aggressor know help has been called would increase the danger.
Duress code
A pre-agreed word, phrase or PIN that signals danger without a button, useful when the person's hands are not free or a button cannot be reached.
Man-down and no-movement detection
A man-down alarm uses the phone or device sensors to detect a fall, impact or a prolonged lack of movement and raises an alert automatically, protecting people who are incapacitated and cannot press anything.
Missed check-in
Scheduled check-ins that escalate automatically if the person does not confirm they are safe, a safety net for staff working alone or in higher-risk locations.
Where are duress buttons used?
Duress buttons protect people wherever there is a risk of confrontation, coercion or isolation. The following sectors are among the most common, though any organisation with staff who face the public, handle valuables or work out of sight can benefit.
Healthcare and social care
Clinicians, community carers and reception staff regularly face aggression, and many work alone in patients' homes. A duress alarm gives them a fast, discreet way to summon help and gives employers a record that they took reasonable steps to protect them.
Retail and hospitality
Front-line staff deal with theft, abuse and occasionally violent customers. A discreet duress trigger lets them call for support without escalating a confrontation in front of other customers.
Banking and finance
Counter and branch staff are at risk of robbery and coercion, where a silent duress alarm is essential because any visible reaction could increase the threat.
Education
Teachers, campus and front-desk staff need a quiet way to summon help during an aggressive incident or lockdown, without alarming students or the individual involved.
Field and travelling teams
Engineers, surveyors, inspectors and staff working across multiple sites or overseas are often out of sight of colleagues. For these teams an app-based duress button, backed by travel security and real-time location, protects people wherever they go, which fixed hardware cannot. It is also the natural fit for lone worker scenarios.
The benefits of a duress button for your organisation
A duress button is a small investment against a serious risk. Beyond the obvious safety case, it delivers several benefits that matter to security, HR and operations leaders.
1.Meeting your duty of care: it gives you a concrete, evidenced control for the risk of violence and coercion, rather than a policy that exists only on paper.
2.Faster, better-targeted response: an alert with real-time location means responders go straight to the person, instead of losing minutes working out where they are.
3.Confidence and retention: staff who know they can summon help quickly feel safer and are more willing to take on front-line, field and out-of-hours work.
4.Deterrence: visible safety measures can discourage aggression in customer-facing settings.
5.Evidence and accountability: a full audit trail supports insurance, compliance and honest post-incident review.
Duress alarms, standards and compliance
There is no single law that mandates a duress alarm, but UK employers carry a general duty of care under health and safety legislation to protect staff from foreseeable harm, including violence, aggression and the risks of working alone. Where a risk assessment identifies those risks, a duress alarm is a reasonable and widely expected control.
When you evaluate providers, look for alignment with recognised standards, such as BS 8484 for lone worker service providers and monitoring through an accredited Alarm Receiving Centre. These give you assurance that alerts will be handled to a consistent, audited standard. This section is general guidance and not legal advice, so confirm the specific obligations that apply to your sector and location.
How to roll out a duress button across your workforce
Choosing a solution is only half the job. A duress button protects people only if it is deployed thoughtfully and actually used. A simple rollout follows five steps:
-
Assess the risk. Identify who is exposed, to what, and where, so the solution matches the real threat rather than a generic one.
-
Choose the right form factor. Match the trigger to how people work: fixed or wireless for static sites, app-based for mobile, lone and travelling staff.
-
Define the response and escalation. Decide who receives alerts, how they acknowledge them, and what happens if they do not, before anyone relies on the system.
-
Train your people. Make sure staff know how to raise an alarm, including silent and duress-code options, and that they trust it will work.
-
Test and review. Run regular tests, check response times, and review every real incident so the system improves over time.
How Vismo approaches duress and panic
Vismo takes a software-first, app-based approach to duress and panic. Rather than tying safety to a fixed device in one location, Vismo builds discreet duress and panic button functionality into the mobile app your people already carry, so they are protected whether they are in the office, out in the field, or travelling internationally.
When a user raises an alert, Vismo sends it instantly to your security or response team with the person's real-time location, and can escalate automatically if it is not acknowledged. Alerts can be monitored in-house through the Vismo Monitor App and Vismo Secure Portal, or routed to 24/7 monitoring. And because duress rarely happens in isolation, it connects to Vismo's wider safety platform, including geofencing and mass notification, so you can protect individuals and communicate with your whole workforce from one place.
The result: no hardware to manage, protection that travels with your people, and an auditable record that helps you meet your duty of care.
Duress button FAQ
How much does a duress alarm cost?
Cost depends heavily on the approach. Fixed and wireless hardware carries per-device purchase, installation and maintenance costs that scale with the number of staff and sites. App-based solutions are typically licensed per user, which removes hardware costs and makes them far easier to scale across a mobile workforce. Request a tailored quote based on how many people you need to protect and where they work.
Are duress alarms a legal requirement in the workplace?
There is no law that names duress alarms as mandatory, but UK employers have a general duty of care under health and safety legislation to protect staff from foreseeable risks, including violence and aggression. Where a risk assessment identifies that threat, providing a means to raise the alarm and summon help is a reasonable and widely expected control. This guidance is general and not legal advice, so assess your own obligations for your sector and location.
What is the difference between a duress button and a duress code?
A duress button is a physical or in-app control that a person presses to signal danger. A duress code is a pre-agreed word, phrase or PIN that does the same thing without a button, for example a code entered on a keypad or a phrase spoken on a call that quietly tells colleagues the person is being coerced. Many organisations use both: a button for a fast, silent press, and a code for situations where pressing a button is not possible.
What happens if there is no mobile signal when the alarm is triggered?
This is a key question for any app-based approach. A capable solution queues the alert and the location and sends them the moment connectivity returns. For people working where there is no mobile coverage at all, it can fall back to satellite devices so an alert can still get out. Ask any provider exactly how their system behaves with no signal before you rely on it.
Can a duress alarm system integrate with our existing security setup?
It should. Vismo takes a consultative approach to integration and can work alongside the hardware and systems you already have, feeding duress and panic alerts into your wider response and monitoring workflow rather than replacing everything. If you have specific devices or platforms in place, raise them early so they can be scoped into your setup.
How quickly does help arrive after a duress alarm is raised?
That depends on your response model, not just the device. The alarm itself is near-instant; what governs the real response time is who receives it and how they are set up to act. With a defined escalation chain, acknowledgement, and professional monitoring where needed, a duress alarm should reach a responder within seconds and trigger action without delay. This is why the response process behind the button matters as much as the button itself.
Can employees use their own phones for a duress button?
Yes. An app-based duress button installed on the employee's own smartphone is often the fastest and most cost-effective way to protect a mobile workforce, because there is no hardware to issue or maintain. The Vismo Locate & Protect App runs on the phone people already carry, so protection is always with them.
How often should a duress alarm system be tested?
Test regularly rather than once at installation. A common approach is a documented test on rollout, then periodic checks (for example monthly or quarterly) of the trigger, the alert, the location accuracy and the response chain. Testing after any change to staff, sites or the response team is just as important, so that the system is known to work before it is needed.
