Over 12 Years of Experience in GPS Tracking


CDMA 1X Tracking Device
The GV300VC is a compact GPS tracker designed for a broad range of vehicle tracking applications, including monitoring driver behavior.  Multiple I/O interfaces allow the device to be used for controlling or monitoring external devices.  A GPS receiver offers superior sensitivity and faster fixes times, and CDMA2000-1x capabilities provide real time and intermittent tracking through a backend server and mobile devices.

The GV300VC is equipped with a 3-axis accelerometer for motion detection and conserving battery life, and is compatible with a wide range of reporting options, including panic alerts, geo-fencing alerts, harsh driving notifications, low battery alert, and intermittent GPS position reports.
