GL500

Hibernating Asset Tracking Device
Product Description: 

 

The GL500 is a powerful GPS tracker designed for fixed asset tracking applications. It is powered by user replaceable CR123A lithium battery pack. Configuration allows it to wake up on a preset schedule to check if it needs to shift from dormant to active status and/or send update of its current location, and then return to a dormant state. Optimally configured, it will operate autonomously for 1800 days. Its built-in 3-axis accelerometer allows the GL500 to detect asset movement and transmit an alert message. The integrated @Track interface protocol allows the GL500 to communicate with a customer mobile phone or a backend server via GPRS/SMS and transfer reports like GPS position. System integrators can easily incorporate the GL500 into existing tracking systems based on this full featured protocol.
