How does GF22 Work?

GF22 GPS tracker works by using a combination of GPS (Global Positioning System) and cellular network technologies. The device has a built-in GPS module and antenna so it can receive coordinates from satellites. Once the device gets the coordinates, it sends them to a remote server by using the cellular GPRS network.

The server then processes these coordinates (geo-coding) and makes it available to access through a smartphone app or web tracking software. The user can view the location of the GF22 tracker in real-time and set up geofencing alerts to receive notifications when the tracker enters or exits a specified area.

GF22 GPS tracker also has a built-in rechargeable Li-ion battery. Depending on tracking interval or usage, it can last for several days. The device is charged by a USB cable when power is low. With the SOS button, the user can send out a help message and call by pressing the button. With a microphone, the caller can listen to the voice around GF22, as well user can control the device to record the audio around the device.
