GF22 GPS tracker is a small, and portable device. It is used to track the location of people or objects or vehicles. It uses GPS technology to determine the precise location of the device and shares the location via GPRS network to the user’s phone or web tracking software. The GF22 is designed to be discreet and easy to use, making it a popular choice for tracking vehicles, assets and kids.

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.
