Rechargeable Trailer Tracking Unit
Product Description: 
The GV600W Series are a series of compact waterproof GPS trackers designed for a wide variety of vehicle tracking applications. They have multiple I/O interfaces that can be used for monitoring or controlling external devices, including a 1-wire interface used for temperature monitoring. Their built-in GPS receiver has superior sensitivity and fast time to first fix. Their different models allow the GV600W Series’ location to be monitored in real time or periodically tracked by a backend server and mobile devices. System integration is straightforward as complete documentation is provided for the full featured @Track protocol. The @Track protocol supports a wide variety of reports including emergency, geo-fence boundary crossings, external power supply monitoring and scheduled GPS position.
