Multi-purpose Mini Asset Tracker

The STU690 (with its holder) is a water resistant (IP66 compliant) rugged, hard-cased multi-purpose mini 3G tracking device for a variety of uses such as asset tracking, vehicle/motorcycle tracking and personal tracking.

The STU690 works autonomously by using its own built-in battery and its superior internal antennas for both of GSM and GPS which eliminate the need for wired antenna.

If you want to track an object, simply place the STU690 into the box or carry bag where the object is to be contained. The STU690 can track the locations by receiving alert notifications whenever the object enters or leaves the pre-set zones (Geo-fences)

In addition to the 3-axis accelerometer, the STU690 has many functions: motion detection and industry leading low power-consumption algorithms that use less than 8uA in sleep mode of no-network status.

This non-wiring device is so small that it can be hidden after being placed. The dust proof and water resistant STU690 is suitable for covert tracking even in rainy and snowy weather conditions. The STU690 is ideal for tracking various objects such as lone workers, kids, vehicles, motorcycles, snowmobiles, boats and fixed/moving assets like valuable merchandise, computers, electronic equipment, outdoor machinery, and other valuable items and cargos.

The external battery 18.2Ah of longer battery-life is an option available for those who need a GPS tracker of a longer operation(e.g. 2 to 6 weeks)of continuous travel time, depending on the preset time of reporting intervals.
