Indoor geolocation: protect your isolated workers where GPS stops.

Written by editor

In lone worker emergencies, precise location is decisive. In large buildings, underground parking lots or logistics warehouses, for example, you need to opt for a suitable solution.

Indoor geolocation for lone workers: what is it?

The indoor geolocation or indoor localization ensures the continuity of your lone worker's protection device on your premises. This system is necessary when GPS localization stops at your door and it's difficult to locate your lone worker once on site to rescue him.

Let's take Eric's example for a better understanding.
Eric is a technician and lone worker on a large production site. The walls strongly attenuate GPS signals. So, if he needs to, he can't be located inside the building he's working in.

Today's lone-worker protections give employees like Eric accurate geolocation outdoors. However, they are still approximate indoors. That's where indoor geolocation devices come in.

Indoor localization: the Scutum Premium Services solution.

Scutum Premium Services offers a complete PTI solution in response to this need. Our devices, coupled with indoor radio beacons, locate the lone worker in an area not covered by the GPS network.

The DATI used by the lone worker automatically recognizes and registers nearby beacons within a 10m radius. So, in the event of an alert, it communicates to the remote monitoring center the names of the last 3 beacons on its path. Rescuers can then pinpoint Eric's exact location and take swift action. They can then intervene quickly.
