GV55 Lite

Ультратонкий и Высокотехнологичное Автомобильное Устройство Слежения
Описание Продукта: 


GV55 Lite is a powerful GPS tracker designed for vehicle tracking applications. With superior receiving sensitivity, fast TTFF (Time to First Fix )  and Quad-Band GSM frequencies  850/900/1800/1900,  its location  can be monitored  in  real time or periodically tracked by  a backend server or other specified terminals .The GV55 Lite has multiple input / output interfaces that can be used for monitoring or controlling external devices. Based on the integrated @Track protocol, the GV55 Lite can communicate with a backend server through the GPRS/GSM network to transfer reports of emergency, geo-fence boundary crossings, GSM Cell ID, or scheduled GPS position as well as many other useful functions. System Integrators can easily setup their tracking systems  based on the full-featured @Track protocol.
