GPS

'Applications* The My Guard Mini Automatic Vehicle Locator integrates GPS and GSM. Its compact size and low power consumption can provide the vehicles multiple applications. My Guard can offer a variety of functionality and capability. The applications are for vehicle monitoring, tracking, remote site control and management. 'FeaturesCompact size / Easy Installation * Dimension : 105mm (L) x 75mm (W) x 35mm (H) Location and Speech Report on Request or Alarm * Built in E-map and voice processing circuit * To report the real location by voice through GSM when it is in request mode or the alarm system mode is activated, this feature makes the users quickly track the car, eliminate the data transfer process from the location expressed by the degrees of longitude and latitude, into the real location on map. With above speech report, it can quickly get the vehicle data and reduces the communicating expense by SMS. GSM Communication * With GSM voice and GSM SMS GPS Navigation * It is built in 12 channel GPS receiver to provide the users the synchronized message receiving service and the GPS navigation, including the information of user locator longitude, latitude, altitude and timing. 4 Digital inputs * The system provides 4 set digital inputs, they can be directly connected to the required sensors for communication use, the remote system can fully track the car status. 1 RS232 Ports With 1 RS232 serial port for full duplex communication, to provide GPS NMEA0183 data or software upgrading SOS button * Provide SOS button for emergency use. Intelligent Power Management & Battery low detection * The product is with software for power management, built in A/D converter to detect car battery voltage and provide the function of low battery warning. System backup battery (Optional) * Built in rechargeable NiMH battery pack as a back up power supply during the failure period of car power supply (such as low voltage or damaged by the external force). RTC (Real Time Clock) backup battery * It is built in back up battery to provide the real time clock during the failure period of car power supply.
