Why invest in a dedicated emergency detection device when your smartphone already offers safety features?
It’s a valid question — and one we often hear at ADRESYS. After all, smartphones are everywhere and packed with smart technology.
But when it comes to workplace safety, especially in high-risk environments, the details matter. That’s why we’ve taken a closer look at both solutions: their strengths, their limitations, and what they really offer when seconds count.

Indoor positioning systems ensure that workers in an emergency can be located quickly by the ANGEL React System, even in large buildings or places without adequate GPS reception. To provide the highest possible safety, we have developed Location Beacons. However, for those who want to save on the cost and effort of acquiring and installing such beacons, we have good news: indoor positioning is now also possible via Wi-Fi access points.

The common belief is that emergencies in everyday (work) life are easy to detect. Even a smartphone can often determine whether a person is moving or motionless—and trigger an alarm if needed. But isn’t the smartphone often just lying somewhere out of reach, making it impossible to detect an emergency? And how well can such a device distinguish between motionlessness and focused, quiet work?
Why isn’t emergency detection always what it seems—and what does usability have to do with saving lives? Read our article to find out.
