CAREU - U1 Lite+ LTE

The CAREU U1 Lite+ LTE GPS tracker is a compact, cost-effective vehicle telematics device purpose-built for fleet management and video-enabled telematics. Green-Gps compatible out of the box, the U1 Lite+ brings reliable GPS/GLONASS/QZSS position tracking together with OBD II/CAN diagnostics, fuel monitoring and advanced sensor integration so operators can get real-time tracking and telemetry from mixed fleets with minimal integration effort.

Designed for use in commercial vehicles, heavy trucks and refrigerated fleets, the U1 Lite+ LTE family supports LTE Cat 4/Cat 1 plus 3G/2G fallbacks and optional internal Wi‑Fi hotspot for video transmission (Cat.4 version). The device also supports remote configuration and FOTA firmware updates, making it a practical, Green-Gps compatible solution for operators focused on anti-theft measures, detailed engine telemetry and scalable fleet tracking.

Key Highlights

• Green-Gps compatible GPS tracker providing continuous real-time tracking and fleet management data.
• Multi-network connectivity: LTE Cat 4/Cat 1 plus 3G/2G support for broad coverage and fallback.
• Built-in GPS/GLONASS/QZSS GNSS reception and 3‑axis accelerometer for harsh event and impact detection.
• Integrated OBD II/CAN interpretation (J1939/J1708) for engine telemetry (fuel level, RPM, odometer, engine temperature).
• Advanced fuel monitoring with ultrasonic and external sensor support for accurate fuel reporting.
• Video telematics-ready with optional internal Wi‑Fi hotspot for video transmission (Cat.4 models).
• Anti-theft features including remote engine immobilization and GSM jamming detection.
• Remote configuration and FOTA via FTP for simplified device management at scale.

How It Works with Green-Gps

The U1 Lite+ connects to Green-Gps to deliver position, diagnostics and sensor data in real time. Once installed in a vehicle, the tracker uses its cellular link (LTE/UMTS/HSPA/GPRS/EDGE) to stream GNSS fixes, CAN/OBD telemetry and sensor inputs to the Green-Gps platform for live monitoring, alerts and historical reporting. Green-Gps reads the device’s standardized messages and makes telemetry available in dashboards, geofence rules, and automated reports.

• Real-time location and telemetry updates transmitted over LTE/3G/2G or via SMS/FTP where available.
• Engine data from OBD II/CAN (fuel level, odometer, RPM, engine temperature) visible within Green-Gps dashboards.
• Geofence reporting (circular and polygonal) with configurable alerts for arrivals, departures and violations.
• Fuel monitoring integration: ultrasonic and external fuel sensor readings feed fuel reports and consumption analysis.
• Remote immobilizer support for anti-theft workflows; Green-Gps can trigger immobilization according to operator policies.
• Video-ready connectivity: Cat.4 models with internal Wi‑Fi hotspot support video transmission for dash cams and surveillance (video handled through Green-Gps-compatible ingest or third-party integrations).
• Optional Bluetooth configuration and peripherals can be paired and surfaced to Green-Gps where supported.

Technical Overview

Use Cases

• Fleet anti-theft and immobilization — remote engine immobilizer and GSM jamming detection help protect assets and enable rapid response.
• Video telematics and surveillance — Cat.4 models with Wi‑Fi hotspot support dash cam connectivity and live video for security and incident review.
• Fuel management optimization — ultrasonic fuel sensors and CAN/OBD data enable accurate fuel monitoring and consumption reporting.
• Cold-chain monitoring — 1‑Wire and analog temperature sensors support refrigerated transport and compliance tracking.
• Smart city and heavy-vehicle telematics — suitable for garbage truck tilting control, school buses, international logistics and heavy-truck diagnostics.

Why Choose This Tracker with Green-Gps

When integrated with Green-Gps, the CAREU U1 Lite+ delivers a balance of cost-efficiency and capability for fleets that need more than basic GPS. Its support for OBD II/CAN diagnostics brings engine telemetry (odometer, RPM, engine temperature, fuel level) into Green-Gps’s fleet management workflows, while the device’s multi-network connectivity and optional Wi‑Fi video hotspot make it a practical choice for video-enabled telematics. Anti-theft functions including remote immobilizer control and GSM jamming detection add security layers that fleet managers can automate through Green-Gps policies.

Green-Gps compatible by design, the U1 Lite+ minimizes integration overhead: standardized telemetry feeds, geofence reporting and FOTA via FTP allow operators to scale deployments across vehicles and regions. Whether your priority is real-time tracking, detailed telemetry for maintenance and fuel monitoring, or video telematics for security and compliance, the U1 Lite+ provides the interfaces and remote management features needed to keep total cost of ownership low while delivering actionable data.
