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.
Features
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
