Multi-purpose MiniAsset Tracker

The ST940 (with its holder) is a water resistant (IP66 compliant) rugged, hard-cased multi-purpose mini tracking device for a variety of uses such as asset tracking, vehicle/motorcycle tracking and personal tracking.

The ST940 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 ST940 into the box or carry bag where the object is to be contained. The ST940 can track the locations byreceiving alert notificationswhenever the object enters or leavesthe presetzones (Geo-fences)

In addition to the 3-axis accelerometer, the ST940 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 ST940 is suitable for covert tracking even in rainy and snowy weather conditions. The ST940 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 optionavailable for those who need a GPS tracker ofa longer operation(e.g. 2 to 6 weeks)ofcontinuous travel time, depending on the preset time of reporting intervals.
