The TLD2-L 4G LTE is a compact, plug-and-play OBDII GPS tracker built for easy, maintenance-free vehicle tracking and rapid integration with Green-Gps. Designed to be inserted directly into the vehicle’s OBDII port, the TLD2-L delivers frequent real-time tracking updates, crash and aggressive-driving detection, and Bluetooth Low Energy (BLE) accessory support — making it ideal for fleets, light commercial vehicles, and connected asset programs that require reliable telemetry and driver behavior insights.
As a Green-Gps compatible GPS tracker, the TLD2-L brings reliable GNSS performance, LTE-M/NB-IoT cellular connectivity with GSM fallback, and on-device buffering for extended offline operation. Its built-in accelerometer, ignition alerts, disconnection detection with backup battery support, and FOTA capability let fleet managers deploy at scale while retaining remote control and firmware management through Green-Gps’s platform.
Key Highlights
- Plug-and-play OBDII installation: no tools or wiring—install in seconds for fast field deployment.
- Real-time tracking as often as every 3 seconds with large offline storage (up to 60,000 points) for reliable telemetry when coverage lapses.
- 4G LTE Cat M1 and Cat NB2 connectivity with GSM/EDGE fallback for broad network compatibility.
- Built-in 6-axis accelerometer for harsh acceleration, harsh braking, sharp turns, collision and crash detection.
- BLE (4.0/5.0 compatible) for temperature/humidity sensors, door/contact sensors and wireless relays to enable remote immobilizer or control functions.
- Ignition on/off alerts, disconnection alarms, low-battery warnings and an internal buzzer for driver alerts or reckless-driving notifications.
- FOTA support and TCP/UDP/MQTT/SMS transport protocols for remote management and robust data delivery to Green-Gps.
How It Works with Green-Gps
When paired with Green-Gps, the TLD2-L feeds continuous location and telemetry to the platform using secure transport protocols. Green-Gps ingests GNSS fixes, accelerometer events and BLE sensor data to present live maps, behavior analytics and actionable alerts for fleet management, anti-theft response and condition monitoring. The device’s buffering and scheduled reporting ensure data integrity even through network gaps.
- Real-time location and telemetry updates (configurable reporting intervals, down to every 3 seconds).
- Driving behavior events from the 6-axis accelerometer: harsh acceleration, harsh braking, sharp turns and collisions for fleet safety analytics.
- Ignition on/off alerts and disconnection alarms with backup battery support for anti-theft and tamper detection.
- BLE sensor integration for temperature, humidity and door/contact status; wireless relays can be driven for remote immobilizer or control actions.
- Scheduled reporting by time, angle or distance and transport over TCP/UDP/MQTT/SMS for flexible integration and telemetry delivery to Green-Gps.
