Ultra-long Standby Time Tracking Device
Product Description: 

The GPS locator GL300A is a perfect fit for monitoring multitude temporarily-dispatched, outsourced vehicles and containers in logistics industry. It boasts ultra-long standby time with large-capacity internal battery and low power consumption. Its power button is pressed for direct usage, while no installation is required at all. GL300A also functions to monitor the real-time environmental status as it is designed compatible to high-accuracy temperature and humidity sensor and optical sensors. The embedded @Track protocol supports abundant reports and allows GL300A to be easily incorporated into existing tracking systems by integrators.
