GL3000W Series

WCDMA/GSM Advanced Asset Tracker
Product Description: 


The GL3000W Series are a series of water resistant GPS trackers designed for lone worker, vehicle, pet and asset tracking applications. The thumb sized button makes the series ideal for applications requiring rapid notification of emergency alert or regular setting of geo-fence based on current locations. Their built-in GPS receiver has superior sensitivity and fast time to first fix (TTFF). Their WCDMA allows the GL3000W Series' location to be monitored in real time or periodically tracked by a backend server or other specified terminals. Their built-in 3-axis accelerometer allows motion detection and extends battery life through sophisticated power management algorithms. 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, low battery and scheduled GPS position.
