Multi-funcional Vehicle Tracker

The ST300, designed and manufactured by Suntech in Korea, is a feature-rich and technologically advanced GPS vehicle tracking device targeted in usage mainly for high-end segment clients.

The ST300, the latest evolution version of vehicle tracking/telematics solution device of Suntech, functions accurately by collecting location data through a built-in high sensitivity GPS receiver and various vehicle conditions through 14-pin (i.e a 10-pin port plus another auxiliary 4-pin port) event lines, and interacts remotely in real time with its server by using GSM/GPRS technology.

Key advantage of the ST300 is that it has a wide range of features or variants to meet various needs of customers. Based on our plentiful telematics device manufacturing experience and intimate market knowledge about tracking devices, we have applied truly practical advantages of this product category into product concept of the ST300 such as free mounting DPA (Driving Pattern Analysis) and other useful functions.

Based on the functions available on the ‘ST300B’ (i.e. a standard version), more functions can also be optionally available to meet specific needs of the users requiring customization. In addition to the basic functions of the standard version, some of the following functions can be included as optional items:
