Weight 180g
Housing Non-branded housing for optional white-labeling.
IP/IK Rating Ultra-rugged and waterproof IP68 and IK07-rated housing ensures the Oyster3 LoRaWAN can withstand impact, fine dust, and brief submersion
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 supplied.
Operating Temperature -30°C to +60°C – for operation in extreme temperatures use LTC batteries
GPS Antenna Internal
RF Antenna Internal
3-Axis Accelerometer 3-Axis Accelerometer to detect movement
Diagnostic LED Diagnostic LED indicates operation status
On-Board Speed and Heading Current speed and heading is reported with each position update


Battery Life Monitoring Periodic battery status uplinks give a breakdown of power use
Geofence Alerts The server can use device location to create geofences and alerts if an asset enters or leaves designated locations
Periodic or Movement-Based Configure parameters to send updates based on set time intervals or when movement occurs. Adaptive tracking technology detects when the device is on the move and increases the update rate, providing detail when you need it while conserving battery when stationary.
Sleep Mode Stationary devices enter sleep mode until movement occurs to conserve battery life and optimize data usage
Theft Recovery Reduce or minimize asset loss and theft


Flexible Configuration Configure device parameters such as position update rate, movement and accelerometer settings, and more to fit any tracking application.
Configuration App Manage device firmware updates and parameters via DM-Link provisioning tool. Some parameters can be changed via downlink.


Third-Party Integration Easy integration with comprehensive documentation and a flexible and open payload format


Data Security LoRaWAN® networks use AES-128 Encryption so your data is protected


Manufacturer’s Warranty Two-year manufacturer’s warranty. Exclusions apply.
