Internal or external antennas allow for a variety of mounting options, while input and output options allow users to add different sensors for integration with the many alert and reporting options through REDGPS tracking software. GTX7 is a powerful tracking device with security features. It features a super-sensitive GPS module (low-power Sirf star III chipset) and a four-band GSM/GPRS modem. The GPS and GSM/GPRS antennas are integrated into the device, allowing for easy installation and reducing the possibility of the device being found by not finding antennas connected to the device. Its low power consumption and backup battery allow the GT400 to continue operating even if the vehicle's power is removed.
