Описание Продукта: 


GV55 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 has multiple input / output interfaces that     
can be used for monitoring or controlling external devices. Based on the integrated @Track protocol, the GV55 can communicate     
with a backend server through the GPRS/GSM network to transfer reports of emergency, geo-fence boundary crossings, low     
battery, 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.
