FM4100 is a GPS terminal with GSM connectivity, capable of obtaining coordinates and transferring them through the GSM network. This device is perfectly suitable for applications where remote object location acquisition is needed. So you can track your remote objects (trucks, cars, boats, etc.) quickly and easily. It has the option of a rechargeable battery inside and a special controller for power management. There is also the option to use an external backup battery. Therefore, it can operate for a maximum of 48 hours in normal mode (GPRS transmission) with an external backup battery. FM4100 can perform tasks on remote objects, such as monitoring temperature, engine status, fuel consumption, truck door control, etc. In case of connection loss, FM4100 can store up to 8,000 records (optionally 64,000 records), and once the device connection is established, it will send stored data via GPRS. So you won't lose your data (coordinates, sensor data, etc.). The aluminum casing of the device is very robust and perfectly suitable for installation in rough environments.
