GV55 Series

Mini Vehicle Tracking Device With Internal Battery
Product Description: 


The GV55 Series are a set of mini GPS trackers designed for a wide variety of vehicle tracking applications. The Series include two models based on either quad band GPRS/GSM subsystems or both GPRS/GSM and UMTS subsystems, allowing their locations to be monitored in real time or periodically tracked by a backend server or mobile device. The Series boast multiple I/O interfaces that can be used for monitoring or controlling external devices. Their embedded GPS receiver has superior sensitivity and fast time to first fix. The built-in 3-axis accelerometer allows motion detection and extends battery life through sophisticated power management algorithms. 

  • Extremely compact enclosure 63mm*50mm*21.8mm
  • Small size allowing easier installation
  • Driving behavior monitoring and incident notification
  • Designed for insurance and car leasing applications
  • Multiple I/O interfaces for monitoring and control
  • Internal u-blox chipset
  • Internal 3-axis accelerometer supporting driving behavior monitoring, power saving and motion detection
  • Embedded full featured @Track protocol
