What are lone worker devices?
Lone worker devices are wearable or portable safety devices that let an employee working alone call for help and be located quickly in an emergency. A lone worker device typically combines a one-touch panic alert or red alert, man down detection that raises an alarm automatically if the wearer falls or stops moving, and GPS tracking so responders know exactly where the person is. Alerts are sent to a monitoring team, an alarm receiving center or your own security team, who can escalate to emergency services if needed.
What is man down?
Man down is a feature that raises an alert automatically, without the worker having to press anything. Using motion and tilt sensors, the device detects when someone has fallen, been knocked over, or has stayed motionless for too long, and then triggers an alarm and shares their location. It is designed for the moments a panic button cannot cover, when a lone worker is injured, unconscious or otherwise unable to call for help themselves. Man down detection is one of the most important capabilities in any lone worker device, and it is built into the Vismo Lone Worker Badge.

How our lone worker devices work with the Vismo platform
Lone worker devices and your duty of care
US employers have a duty to provide a safe working environment, reinforced by the OSHA General Duty Clause, and that responsibility extends to employees who work alone. Providing a suitable lone worker device, backed by monitoring and a clear escalation process, is a practical way to meet that duty and to evidence it, with a record of alerts raised and responses made. For the wider picture, see our
complete employer guide to lone working.
Who uses lone worker devices?
Choosing the right lone worker device
The best lone worker device is the one your people will actually carry and that matches their risk. A discreet badge suits community and customer-facing roles; a Bluetooth button is a simple, low-cost add-on for app users. When comparing lone worker devices, look for man down detection, reliable GPS tracking, a battery life that fits the working pattern, professional monitoring, and a platform that ties alerts, location and escalation together. Vismo can help you match the right device to each team.
Lone worker devices FAQ
What is man down detection?
A feature that automatically raises an alarm when the device senses a fall or a lack of movement, so a worker who is injured or unconscious still gets help even if they cannot press the button.
Do I need a device or is an app enough?
It depends on the risk. An app suits lower-risk, phone-carrying roles; a dedicated device or the Alert V2 button suits higher-risk or hands-busy work where a discreet, reliable trigger and man down detection matter.
Is GPS tracking on lone worker devices private?
Vismo’s location features are consent-based and designed for safety, so employees understand when and how their location is shared, typically when an alert is raised or a check-in is missed.
How quickly is an alert acted on?
Alerts and location are delivered in real time to the Vismo Secure Portal and monitoring service, so your team or a monitoring center can respond and escalate to emergency services immediately.
Is a lone worker device the same as a panic button?
Not quite. A panic button is pressed to raise the alarm; a lone worker device adds automatic man down detection and GPS tracking on top of that. For the software panic button that turns any smartphone into an SOS device, see our
mobile panic button page.
