Over 12 Years of Experience in GPS Tracking


CDMA 1X Micro Vehicle Tracking Device
As a cost effective micro CDMA tracking option, the GV55VC offers reliable tracking across multiple tracking applications.  Multiple I/0 interfaces allow for monitoring or operating external hardware, and the device's GPS receiver ensures greater sensitivity and faster fix times.

The device supports real time tracking and intermittent tracking options through dual band CDMA200-1x.  Supports additional features including panic alerts, geofence setting and monitoring, external power supply monitoring, and programmed GPS location reports.  Full documentation is provided.
