Smart Asset tracking on remote

The Calculus platform offers tools for complete control in the most diverse areas. Like Smart Assets, asset tracking via a GPS Tracker for monitoring and securing vehicles and mobile or fixed equipment. Or Smart Buildings, for controlling and optimizing, among other things, energy and water consumption, the indoor and outdoor climate and CO2 monitoring via Private LoRa.
Remotely following, monitoring and operating all these things results in profit, both in terms of time and money. Plus: the system leads to a more accurate deployment of (maintenance) staff. 


The Calculus platform has been developed for use in a wide variety of fields. The plug-and-play system is very easy to operate – wherever you are – and you can share insights with third parties in real time.
