"Teltonika FMC920 is a small and intelligent tracker with Bluetooth connectivity, internal GNSS and high-gain GSM antennas, and a built-in backup battery. The 4G Cat 1 technology provides significantly higher bandwidth, lower latency, and improved spectral efficiency.
The model is compact, reliable, accurate, and durable. All its interfaces are more than sufficient for basic tracking. The digital input can be used for monitoring ignition status, door status, or alarm button, while remote vehicle immobilization can be achieved using the device's digital output."
