We designed and patented the Sentinel Anchor to offer precise indoor location tracking and ambient sensor data collection. The Sentinel Anchor is installed on physical infrastructure like dock doors, racks, storage locations, offices, trucks, delivery vehicles and anywhere in between, and will tell any Sentry or Sentinel devices nearby exactly where they are, along with the ambient conditions in the areas. Sentinel Anchors automatically talk with any Sentinel Logger or Sentry that comes nearby. Location, dwell time and sensor information are automatically exchanged between the devices with zero configuration required – it just works.
