TopFly - TLW2-12BL

The TLW2-12BL is a hardwired 4G LTE vehicle GPS tracker designed for fleet management, anti-theft protection, and advanced telemetry. Green-Gps compatible out of the box, this unit brings high-frequency real-time tracking (position updates as fast as every 3 seconds), robust GNSS performance and integrated Bluetooth Low Energy for external sensor support, making it a versatile choice for operators who need reliable location intelligence and vehicle control through the Green-Gps platform.

The TLW2-12BL is built for global deployment with CAT-M1 4G connectivity and 2G fallback, extensive I/O for ignition detection and relay-controlled immobilization, and on-device buffering of up to 60,000 location points for operation across intermittent networks. When paired with Green-Gps, fleet managers gain instant access to live location, telemetry, fuel monitoring, crash and driving behavior alerts, and BLE sensor data for cold-chain or door/temperature monitoring.

Key Highlights

• Green-Gps compatible GPS tracker with real-time tracking down to 3-second updates for precise fleet management.
• Global 4G CAT-M1 coverage with 2G fallback and a comprehensive set of supported bands for worldwide roaming.
• Integrated BLE 5.0 for TOPFLYtech accessories — temperature, humidity and door sensors, plus wireless relays.
• Extensive I/O: ignition detection, multiple digital/analog inputs, digital outputs for remote immobilizer and buzzer control.
• Robust GNSS using Qualcomm Gen 8C (GPS+GLONASS+Galileo+BeiDou) with autonomous accuracy under 2 m CEP and fast TTFF.
• Large offline buffer (up to 60,000 points) and telemetry over TCP/UDP/MQTT/SMS for resilient tracking and reporting.
• Vehicle safety features including crash detection, towing detection, driving behavior monitoring and jamming detection.
• Compact, IP65-rated housing and wide operating voltage (DC 7V–60V) for diverse vehicle installations.

How It Works with Green-Gps

The TLW2-12BL streams vehicle position and telemetry directly to Green-Gps using standard telematics channels (TCP/UDP/MQTT/SMS). Green-Gps ingests GPS/GNSS coordinates, accelerometer-based events, input/output state changes and BLE sensor readings, and then presents them in dashboards, maps and reports. Device-side buffering ensures no loss of history during temporary network outages — buffered points upload automatically when connectivity returns.

• Real-time location and telemetry updates (as frequent as every 3 seconds) — visible in Green-Gps maps and live views.
• Ignition and digital input status for trip detection, PTO and door alarms — integrated into Green-Gps alerts and reports.
• Analog fuel sensor input for fuel monitoring and event-based reporting to Green-Gps.
• Remote immobilizer/relay control via Green-Gps commands supported through the device’s digital outputs.
• Bluetooth sensors (BLE 5.0) such as temperature, humidity and door sensors — sensor telemetry relayed to Green-Gps for cold-chain and security use cases.

Technical Overview

Use Cases

• Fleet management — live vehicle tracking, driver behavior monitoring, scheduled reporting and route replay in Green-Gps.
• Anti-theft and immobilization — ignition detection, relay-controlled immobilizer and remote output control via Green-Gps to prevent unauthorized use.
• Fuel monitoring — analog fuel sensor input and telemetry reporting to manage consumption and detect fuel theft.
• Cold-chain and asset condition monitoring — BLE temperature/humidity sensors paired to the tracker deliver environmental telemetry to Green-Gps for refrigerated trucks and trailers.
• Mixed asset installations — robust I/O and wide voltage range support installations across trucks, buses, vans and industrial equipment.

Why Choose This Tracker with Green-Gps

The TLW2-12BL is a purpose-built GPS tracker for operators who need dependable real-time tracking, rich telemetry and flexible I/O in a Green-Gps compatible package. Its global CAT-M1 connectivity with 2G fallback and a high-performance GNSS receiver deliver precise positions and resilient tracking. Integrated BLE 5.0 expands monitoring to temperature, humidity and door sensors, enabling cold-chain visibility alongside traditional fleet and anti-theft features. With FOTA, remote output control and standard telematics protocols, the TLW2-12BL integrates smoothly into Green-Gps installations to provide scalable fleet management, remote immobilization and comprehensive telemetry without complex custom integration.
