Over 12 Years of Experience in GPS Tracking


Advanced Vehicle Tracking Device
The GV300 vehicle-tracking device is ideal for a broad variety of vehicle tracking applications.  With multiple I/O interfaces, the GV300 has the capability to monitor and/or control external devices.  The device offers professional-grade tracking through greater sensitivity and faster times to first fix.

The GV300’s Quad band GPRS/GSM allows for real time tracking or periodic tracking reports through a backend server or mobile devices.  A 3-axis accelerometer provides accurate driver behavior monitoring and motion detection to preserve battery life.

The device offers multiple reporting options, including geo-fencing, monitoring driving habits, low battery alert, scheduled GPS location reporting, and panic alert.  Complete documentation is provided.
