Interval checks for lone workers via smartphone app
The MultiBel lone worker solution offers several features to ensure the safety of employees working without direct supervision, including:
- fall detection
- emergency button
- motion detection
- check in intervals – interval control
Why use interval checks?
In some work situations, it is sufficient to periodically confirm that everything is fine with the lone worker. For example, some organisations require lone workers to check in by phone every hour. If a check-in is missed, action is taken.
Another method is active monitoring by a colleague or regular patrols by security personnel. However, this approach can be burdensome, especially with short intervals or multiple employees to monitor simultaneously.
The MultiBel solution
MultiBel’s interval check offers an efficient and automated alternative. Within the lone worker app, you can configure how often the employee must confirm their status. If the employee does not respond within the specified interval, an alert is automatically triggered through the MultiBel notification system.
This method allows employees to work safely without the need for constant manual monitoring, while still giving the organisation peace of mind.
Schematic overview of the interval check
Curious how the interval check works? Below is a step-by-step illustration of how this feature is applied in practice.


Periodic check in lone worker app without a connection
A critical aspect of lone worker apps is often a reliable internet connection. If your employees work in areas where connectivity cannot always be guaranteed, MultiBel can still trigger alarms reliably and notify the right people. MultiBel does not rely solely on an internet connection but uses alternative communication channels to ensure maximum availability and to support lone worker patrols reliably.
In addition, the AI-Positioning System (AI-PS) provides accurate indoor location tracking within buildings. In the event of an alarm, the exact location of the person involved is automatically included with the alert, down to floor and room level.
Further development of MultiBel periodic check
Please note: our system is always under development, and the schematic representation in this blog and the screens on our website show a simplified picture of the real possibilities. There are many (choice) elements on which MultiBel can be adapted to your specific wish/ situation.
