The powerful waterproof GPS tracker is 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, then returning to a dormant state. Optimally configured, it will operate autonomously for 1800 days. Its built-in 3-axis accelerometer and temprature sensor allows the device to detect asset movement/temperature change and transmit an alert message.
