As is the case with all electronics, GPS tracking devices need a reliable power source. Wired devices draw negligible power from the vehicle or backup battery. When vehicle power isn’t available, wireless battery-powered devices are used.There’s nothing special about us offering wireless tracking devices. Every provider does. What’s unique are the capabilities of our wireless devices! Our clients can not only ping their devices on-demand, but also reboot their devices and change the tracking interval OTA! Simply amazing!
