Advanced Asset Tracker
Описание Продукта: 


GL300 is a powerful GPS Tracker designed for asset, vehicle, and pet tracking. With superior receive sensitivity, fast TTFF (Time to First Fix) and Quad band GSM frequencies 850/900/1800/1900, its location can be continuously monitored or periodically reported to a backend server or other device. Based on the embedded @Track protocol, the GL300 can communicate with the backend server through the GPRS/GSM network (or SMS) to report emergency alerts, Geo-Fence boundary crossings, low battery and scheduled GPS positions along with several other advanced reporting features. System integrators can easily setup their custom tracking platforms to communicate with the GL300 based on the @Track protocol.
