Sample Projects

Inventory Monitoring

  • Locate assets: Searching for assets by using the web or mobile app and get an overview of all locations with the asset map (street view or satellite) or drill down to locate an individual asset
  • Monitor asset journeys: Follow assets as they move from site to site by estimating routes and distances, logging visited locations, and monitoring stopping times.
  • Detect unusual occurrences: Log where each asset has been, and how long it stayed there to send a notification in case of an abnormality, then warn the asset if it has been stopped for too long at a suspicious place
