How does Mobile Lone Worker Protection Work?

  • Lone Worker On Live Mapping
  • Lone Worker Panic Alarm


MobileLWP from Crystal Ball utilises GPS, GPRS & NFC technology that is already built
into most modern smartphones
in order to monitor the location & welfare status of lone workers in real-time. Support teams can view realtime information on our web based portal and review historical events with our comprehensive audit trails.

Addresses Health & Safety legislation

automates processes that allow organisations to demonstrate a duty of care towards lone workers and address legislation such as the Corporate Manslaughter Act 2007.

Automated welfare protection

full visibility of lone workers on live mapping, together with detailed reports, reduces administrative burden.

One device, lower costs

no additional devices are required, just one discrete everyday device to carry and your employees will only need to remember to re-charge one device.

Lone Worker Protection FAQs

What is a Lone Worker Timed Welfare Session?

Our timed routine welfare check-in sessions (RWC) are our pro-active approach to lone worker monitoring. A lone worker places themselves into a RWC session on the smartphone by choosing a set time which they need to check-in by to tell the monitoring team that they are ok. If the lone worker fails to check in once set the clock counts down and the timer runs out, then an alarm is automatically raised.  

How does MobileLWP's Panic Alarm work?

Panic alarms are raised with a simple and discreet press on a set button (usually volume or standby buttons) on the lone worker's smart phone. This will automatically raise an alarm to head office via our web based monitoring portal with the name, location and time of the alert. It will also dial a emergency telephone number (set by the company or lone worker) so that they can listen into the situation and understand the severity.
