The OTK02-4G Real Time 4G GPS Car Tracking Vehicle GSM GPRS OBD Tracker is a plug-and-play OBD II device designed for immediate installation and fast integration with Flotas control. As a Flotas control compatible tracker, the OTK02-4G delivers real-time tracking and OBD-level telemetry without wiring — ideal for fleet management, individual vehicle tracking, and anti-theft monitoring where quick deployment and reliable diagnostics matter.
Built around a 4G FDD LTE CAT1 cellular module with GSM/GPRS fallback and AGPS assistance, this OBD tracker reports location, mileage and engine status to the supplied web and mobile apps. The unit’s 2 MB offline logger and 150 mAh backup battery keep data flowing through GSM blind spots, giving Flotas control users continuous historical playback and event reporting for better operational control.
Key Highlights
- Plug-and-play OBD II installation: no wiring required — install in seconds to start real-time tracking on Flotas control.
- 4G LTE CAT1 with GSM/GPRS fallback: modern cellular connectivity for consistent telemetry and SMS reporting.
- OBD diagnostics and trip data: mileage, engine on/off status and remote diagnostic reporting via OBD interface.
- Robust offline capabilities: 2 MB flash data logger and a 150 mAh backup battery preserve data during network loss.
- Comprehensive alarms: geo-fence, towing/movement, overspeed, and battery-low alerts for anti-theft workflows.
- Fast positioning with AGPS: quicker time-to-first-fix and reliable route playback for fleet management use.
- Free web and Android app: lifelong access to tracking platform for monitoring, historical replay, and reports.
How It Works with Flotas control
When used as a Flotas control compatible tracker, the OTK02-4G sends GNSS positions and OBD-sourced telemetry to the Flotas control platform (via cellular data or SMS). Flotas control ingests location, event and diagnostic messages into dashboards and alerts so fleet managers and vehicle owners can monitor status, trigger alarms and generate reports in real time.
- Real-time location and telemetry updates delivered to Flotas control’s web and mobile apps for live monitoring.
- Engine on/off and ignition status detected through the OBD II interface — available in Flotas control event logs.
- Mileage and trip history reported via OBD for maintenance planning and utilization tracking.
- Alarms (geo-fence, towing/movement, overspeed, battery low) forwarded as instant notifications through Flotas control.
- Offline logging: 2 MB flash stores data during GSM/GPRS blind spots and syncs when connection resumes.

Why Choose This Tracker with Flotas control
The OTK02-4G combines simple OBD II plug-and-play deployment with robust telemetry and offline resilience, making it a practical Flotas control compatible option for both single vehicles and scaled fleets. Its OBD diagnostics deliver actionable data — mileage, engine on/off events and trip logs — while AGPS and the device’s offline logger reduce data gaps for reliable real-time tracking and historical playback. For fleet managers seeking dependable telemetry, anti-theft alerts, and easy integration into Flotas control’s dashboards, the OTK02-4G offers a low-friction solution backed by a free platform, OEM support and a two-year warranty. It complements broader monitoring strategies (including fuel monitoring workflows and Bluetooth sensor deployments available through Flotas control integrations) without requiring complex hardware installation.
