Lone Worker Monitoring

Automatically sends messages at specific time intervals to confirm workers are safe

Lone worker monitoring for your mobile workforce


  • MOTOTRBO Radios
  • Cell phones

Teldio’s Lone Worker (LW) periodically pings workers to verify their well-being. The app automatically sends messages at specific time intervals to confirm workers are safe. If a worker fails to respond to an ‘alive check’ request within the allocated time frame, an emergency alarm is raised to notify emergency personnel, who receive the alarm directly on their radio or mobile device.

Proactive Lone Worker Monitoring

Lone Worker (LW) is a cost-effective solution to periodically monitor the safety of your mobile lone workers. The application piggybacks on your MOTOTRBO digital radio network to send ‘Alive Check’ messages to your employees directly on their radio handset. Should a worker not respond to an ‘Alive Check’ message, LW triggers an emergency alarm and notifies the appropriate emergency response team or individuals.


LW Customization

Not every working environment is the same, that is why you can configure LW’s settings via the web interface to better monitor your employees.

Time: Define the intervals in which employees
receive ‘Alive Check’ messages.

Response Group: Specify which employee(s) should be
notified if a LW alarm is activated.

Retry Messages: Specify the number of unanswered ‘Alive
Check’ messages are permitted before an
alarm notification is sent to response group.

Enhanced Worker Safety

If a lone worker does not respond to an ‘alive check’ message LW will retry by sending a preset amount of retry messages at shorter intervals. If LW fails to receive an answer, it triggers an emergency alarm and notifies the appropriate emergency response team. This automatic trigger ensures a quick and streamlined response time to the unresponding lone worker.


Frequent Use Cases

  • Workers repairing broken heavy machinery
  • Security guards on patrol during the night shift
  • Maintenance engineers completing their rounds in the facility
Increased Situational Awareness

With LW’s flexible activation and deactivation options, workers, supervisors, and administrators are reassured that lone workers are never left to their own demise. It is a cost-effective solution to ensure that response personnel are notified when a lone worker fails to respond. Individuals responsible to respond to these alarms are contacted on the device of their choice: cell phone, email or radio.


Frequent Use Cases

  • Campus security guards on patrol need backup
  • Construction workers completing jobs in hazardous site need help
  • Workers in lab completing tests with hazardous chemicals have a chemical spill
System Architecture

LW is a software application installed on a Teldio Gateway. The Teldio Gateway interfaces to a radio system using control station(s). The system design allows to periodically monitor mobile workers by sending them ‘Alive Check’ messages directly to their MOTOTRBO™ radios. LW automatically signals for emergency response via AMS when a LW alarm is triggered.

Teldio’s LW is compatible with all DMR display portables & mobiles that support text messaging. The following MOTOTRBO radio network modes are supported:

  • Simplex Mode
  • Repeater Mode
