Asset Tracking

Oyster3 is a light, rugged and powerful asset tracker with Over 10+ years of battery life on user-replaceable 3 x AA Lithium or Lithium Thionyl Chloride (LTC) batteries for extreme temperature operation

It boasts a lot of features such as – 

  • GPS and GLONASS position systems for high precision tracking. 
  • IP67 rated means that the device can withstand extreme conditions. 
  • Battery life tracking means that you can plan ahead and manage your batteries better. 
  • Configure the device to match your reporting needs (1 x, 3 x, 5 x a day …)
  • Adaptive tracking movement based tracking – tracks assets throughout the day and/or when movement occurs
  • Impact detection provides alerts whenever the impact crosses the user-defined G-Force level.
  • Run Hour Monitoring to understand and optimise asset usage.
  • Create custom geofences with speed zones to track assets.

  • Installation – Compact and concealable. Multiple installation options for covertly and easily securing the device to assets with screws, bolts, cable ties, rivets, and more. Stainless steel screws provided
  • Operating Temperature – -30°C to +60°C For operation in extreme temperatures use LTC Batteries
  • Cellular Antenna – Internal
  • GPS Antenna – Internal
  • 3-Axis Accelerometer – 3-Axis Accelerometer to detect movement, high G-force events, and more
  • Diagnostic LED – Diagnostic LED indicates operation status
  • Flash Memory – Store weeks of records if device is out of cellular coverage. Storage capacity for over 1 month of continuous 30-second logging
  • On-Board Speed & Heading – Current speed and heading is reported with each position update
  • On-Board Temperature – The device reports internal temperature which provides an indication of ambient temperature but may not always be precise
  • Auto-APN – Auto-APN allows the device to analyse the SIM card and select the correct APN details from a list that is pre-loaded in the device’s firmware
  • Battery Life Monitoring – ‘Battery Low’ and ‘Battery Critical’ alert levels
  • Geofence Alerts – The server can use device location to create geofences and alerts if an asset enters or leaves designated locations
