TLW1-4 (4G LTE)

Basic Hardwired Tracker with BLE

TLW1-4 is the basic hardwired tracker for tracking powered assets and vehicles, with ignition detection and output for relay. It can also monitor the temperature, humidity, door status, etc, when working with BLE sensors. It’s a widely used model in fleet management, logistics, cold chain, etc, to increase work efficiency and save costs.


Real time and buffer locations

Real time location updates can be as frequent as 3s. Up to 60,000 location points can be saved in buffer if out of network coverage.

Driving behaviour detection

Detecting reckless driving events such as harsh acceleration, turning,braking, crash and speeding

BLE 4.0 for sensors

Compatible with TOPFLYtech’s BLE temp & humi senor TSTH1-B, temp & door sensor TSDT1-B, wireless relay TSR1-B and your own sensors

Compact size​

One of the smallest hardwired trackers in the market

Disconnection alerts​

Alerts for device disconnected from power

Backup battery

Backup power for sending disconnection alerts when power disconencted

Ignition on/off alerts

Alerts for engine is switched on or off

Output for relay

Compatible with wiring relay and BLE relay for vehicle immobilisation for anti-theft
