4G OBD-II GPS Tracker

The 4G LTE OBD-II GPS tracker is a plug-and-play telematics device engineered for rapid installation across commercial fleets, transmitting real-time GNSS positioning, ignition status, and vehicle telemetry directly over cellular networks. Designed for fleet operators and telematics service providers (TSPs), the unit draws operating power from the standard under-dash diagnostic interface while housing an internal backup battery to sustain alerts during power disconnects.

Zero-Wire Installation: Inserts directly into the standard 16-pin diagnostic port without wire splicing or specialized electrical tools.

Real-Time Telemetry: Streams location, speed, mileage, idle duration, and harsh driving events based on customizable time or distance intervals.

Offline Data Buffering: Automatically stores tracking logs in internal flash memory when cellular coverage drops, seamlessly re-transmitting buffered data once signal is restored.

Smart Power Management: Enters deep sleep automatically upon ignition shutdown, eliminating parasitic battery drain on parked vehicles.

Tamper Protection: Triggers instant server notifications if the device is disconnected from the diagnostic port.

Port Location: Locate the 16-pin diagnostic port beneath the driver-side dashboard near the steering column.

Device Insertion: Align the connector pins and push the unit firmly into the port until retention clips engage.

Status Verification: Check internal LED indicators-red for cellular registration, blue for GNSS lock, green for server transmission.

Concealed Routing: Use an optional under-dash extension harness to hide the tracker behind dashboard panels against tampering.

Live GNSS Tracking: Delivers continuous positional updates with tracking accuracy under 2.5m in open-sky environments.

Driving Behavior Analysis: Logs harsh acceleration, sudden braking, sharp cornering, and speeding events to evaluate operator safety.

Diagnostic Trouble Codes: Pulls engine fault codes and health telemetry directly from the vehicle computer for predictive maintenance.

Geofencing & Playback: Establishes virtual boundary perimeters for automated alerts while storing historical route data for review.

Firmware & Protocol Integration: Custom protocol adaptation for proprietary servers; configurable data heartbeat intervals from 10s to 24h.

Enclosure Branding: Laser-engraved housing, custom casing colors (MOQ: 1,000 units), and bespoke retail packaging box artwork.

PCB & Sensor Modifications: Hardware adjustments for specialized telemetric requirements or localized frequency band tailoring.

Open API & Platform Support: Full documentation provided for seamless integration into third-party tracking platforms and commercial software servers, with out-of-the-box compatibility for popular platforms such as Traccar, Wialon, and Navixy.

Passenger Sedans & SUVs: Compatible with gasoline and diesel passenger vehicles manufactured from 1996 (US) and 2001 (EU) onward.

Light Commercial Vehicles: Supports delivery vans, utility trucks, and light transport vehicles utilizing 12V electrical architectures.

Heavy-Duty Limitations: Not intended for 24V heavy-duty trucks using J1939 pinouts unless paired with a dedicated stepdown adapter harness.

Unit Packaging: Individual retail box containing one 4G OBD-II tracking device, port cover, and quick-start reference guide.

Master Carton Specs: 100 units per master carton; carton dimensions: 45 x 35 x 30 cm; gross weight: 6.5 kg per carton.

Global Fulfillment: Anti-static and shock-absorbent protective inner packaging suitable for air freight, ocean cargo, and express courier shipping.
