Small 12v LCD GPS Device for Car Tracking and Auto Positioning Special design for car tracking/positioning, small size, wiring is easy. This model has the features like double channels of GPRS and SMS, voice prompting, remote listen in, trace storage, cut fuel/circuit, mileage record and others. Main Features: ● Based international newest chip, double core structure, powerful ● GPR Sand SMS double channels, TCP and UDP double working mode ● Positioning based GPS reflected wave, assist with base station, strong capacity to prevent blocking to reduce the blind area ●Three proofing design, Quadruple protection for power source, 4 levels watchdog ● Low power consumption ●Build-in high capacity backup battery. ● Build-in TTS voice module to achieve the function of voice report. ●It can update remotely, easy to maintain ● Approved by 3C, and approved by national grade quality authentication. Product Functions: 1.Signal detecting and control: 13 routes signal sensor, 17 vehicle status detecting, intelligence mode and forced mode to cut fuel/circuit, user-defined backup output control. 2. Alarm: 19 alarms, 3 modes of alarm. 3. Monitoring: vehicleautomatic tracking/monitoring, regions setting, geo-fence, GPS mileage statistics, vehicle mileage statistics, blind area supplementary report, traces storage, base station positioning. 4. Voice and phone call: hands free phone, remote listen in, voice reminding device, TTS voice report. 5. Fuel consumption detecting: build-in AD input interface, equipped floater attenuation cable can measure fuel consumption. 6. Remote update: main device’s program was support to remote download; user can renew the program remotely. 7. Protection: Power saving mode: in this mode, GPS device’s working current will drop to20mA@12V when vehicle was in flameout. Car battery over discharge protection: it will switch to supply power by backup battery if car battery’s voltage is very low (9.5V). Over voltage protection: it will cut the external circuit to protect GPS device if the voltage exceeds limit value (36V), backup battery can work for 3h.
