SafeTrx App Provides Automated Emergency Tracking With ‘Alert & Track’ Upgrade

Accurate and continuous position information is critical for Search & Rescue responders. SafeTrx is delighted to announce the release of ‘Alert & Track’ on the SafeTrx app, a new feature to continually monitor the casualty’s location from first alert to recovery.

The SafeTrx app activates automatic tracking once an alarm has been raised via an emergency call or an assistance call, even if tracking was not initially activated. The app will send a location update to the SafeTrx server every 5 minutes.

With the ability to continually track a person in distress, the Search and Rescue authorities will have all the vital information necessary to carry out the search phase, therefore reducing the overall response time.

This crucial feature inspired by members of the SafeTrx’s community resolves potential issues with GPS ‘time to first fix’ and the fact that the casualty could be drifting in the scenario where an alert has been activated on the app.

In designing the feature, the SafeTrx team spoke with Tim Fey, a participant in the PE2EL Surf Ski Challenge race in South Africa, who found himself in an emergency situation and was rescued with the aid of the National Sea Rescue Institute (NSRI) SafeTrx app. Tim shared his story with us , he said “Losing my surfski 2 km out to sea was a frightening experience. SafeTrx played a vital role in my rescue. Using SafeTrx meant my rescuers knew my exact position; it took the search out of the rescue. Seeing the rescue boat coming straight towards me was an incredible feeling.”

Speaking on behalf of the NSRI, Operations Manager Brett Ayres commented “Due to wind and current, your position on the water is always changing. Accurate and continuous position information in open waters is considered one of the most important safety facets. ‘Alert & Track’, for us as rescuers, gives us the critical information we need when every minute counts.”

The feature is now rolled out in Australia, South Africa, and Norway with additional countries releasing soon. Nessa Malone, SafeTrx Product Manager, explained “This release brings an important enhancement inspired by the SafeTrx community. Reducing risk and protecting people’s lives is our priority and a responsibility we take extremely seriously. All of our technological innovation is focused on this clear objective; to deliver the most effective, and protective tracking & alerting solutions available.”

SafeTrx IoT Wearable Sets New Safety Standard with 17km Range

SafeTrx capability as a long-range Search and Rescue device came into its own in recent testing by the Dutch Telecoms company KPN, who have been using the SafeTrx application on the mSafety wearable from Sony to test the range of its Cat-M1 network. The device’s ability to communicate over long distances in harsh conditions could be the difference between life and death for its wearer.

KPN’s tests showed exceptional results with the device continuing to transmit its location to a cell tower from 17km out to sea, long after the standard GSM mobile phone data signal was lost. The range is down to the IoT wearable’s antenna, which measured a signal strength of –140db during the trial. describes any signal weaker than -119db as the ‘dead zone’, with Teltonika citing ‘disconnection’ at anything weaker than -100db.

In an article on its website, KPN said it believed that by fine tuning ‘the innovative LTE-M and optimising the settings, an extension to 30, maybe 60, and theoretically 100 kilometres is possible.’

Extended range and signal reliability are central tenets of the improvements in Search & Rescue technology, both of which are dependent on the wearable’s antenna. As the KPN article explains, ‘This group of equipment is of the Cat-M1 type. But the most important thing is that the network also continues to work in places where a normal telephone no longer has a signal. This allows Cat-M1 devices to stay in contact at a much greater distance from the masts, but also in basements and crawl spaces, for example.’

SafeTrx application on the mSafety wearable from Sony is the evolution of the SafeTrx mobile app which was involved in more than 500 missions in the last year. On the wearable alerts can be raised from the device via large user-friendly buttons even with cold and wet fingers. The portable, rugged, water-resistant features of the wearable make it a much more user-friendly version of the mobile app. People who find themselves in very vulnerable situations now have a simple and easy way to call for help.

In alert mode the device will also transmit the user’s health data back to the emergency services. This means the right crew can be dispatched from the outset. It may be a rescue-only operation, or if needed a medical team can also be sent, improving the chances of a positive outcome for the person needing help.

‘We are delighted to see KPN use our wearable to test the strength of their LTE-M signal, and at –140db, the results are truly outstanding, with a current range of 17km, and according to KPN further distances, much further, are potentially possible.’ says John Murphy, CEO of SafeTrx. ‘Being able to accurately pinpoint the location of the person needing help, means that no time is wasted getting the help they need to them. SafeTrx takes the search out of search and rescue, and the extremely positive results from these tests, both in range and accuracy means that together we can save even more lives.’

The SafeTrx Application on the mSafety wearable platform from Sony will go on sale to enterprise customers in early 2020.
