The TLW2-12BL has multiple I/Os that can be used for ignition detection, relay, SOS button, analog fuel sensors, or other accessories. When working with BLE sensors, it can monitor temperature, humidity, door status, etc. Real-time location updates can be as frequent as 3 seconds and up to 60,000 location points can be stored in the buffer if out of network coverage. It supports global 4G CAT-M1 network bands with 2G backup and detects reckless driving events such as harsh accelerations, turns, braking, collisions, and speeding.
