Business Problems We Solve
Lack of Real-Time Fleet Visibility & Route Inefficiencies
Fleet operators unable to locate delivery vehicles in real time, leading to unauthorized vehicle detours, excessive idling, and delayed dispatches.
Un-monitored Harsh Driving & Accelerated Vehicle Wear
Drivers engaging in aggressive acceleration, harsh braking, and speeding without company knowledge, driving up fuel costs and accident risks.
Unexpected Vehicle Breakdowns on Highway Routes
Commercial trucks breaking down mid-transit due to un-monitored engine diagnostic trouble codes (DTCs) and battery voltage drops.
Cluttered, Distracting In-Vehicle Touch Interfaces
In-cab driver navigation and dispatch tablets featuring tiny text and complex menus that distract drivers while vehicles are in motion.
Who Benefits Most
Commercial fleet management and logistics transport operators managing 20 to 5,000+ vehicles
Electric vehicle (EV) manufacturers building companion mobile apps and telematics dashboards
Car rental and self-drive companies needing remote vehicle immobilization and geofence tracking
Cold-chain refrigerated transport operators monitoring cargo temperatures alongside vehicle speed
When to Consider Alternatives
Basic consumer personal car GPS tracking fully served by off-the-shelf consumer gadgets
Direct vehicle engine ECU reprogramming or performance chip tuning
Operations where vehicles lack cellular network coverage for months at a time

What hardware telematics devices do you support?
We support standard telematics hardware protocols from leading global manufacturers—including Teltonika, Queclink, Concox, CalAmp, and standard OBD-II ELM327 devices—as well as custom microcontrollers (ESP32/STM32).
Can the system track vehicles when they enter tunnels or areas without cellular signal?
Yes. Professional telematics hardware logs GPS coordinates and sensor readings to internal flash memory when cellular signal is lost. Once the vehicle re-enters network coverage, the device uploads the cached route, preserving complete trip history.
Can this system integrate with our existing ERP or dispatch software?
Yes! We provide complete REST and WebSocket APIs, allowing live vehicle locations, estimated arrival times (ETA), and trip completion events to flow directly into your ERP or warehouse management systems.
Can we track electric vehicle (EV) specific metrics like battery state of charge?
Yes. For electric vehicles, our telematics parsers extract battery State of Charge (SoC), State of Health (SoH), charging status, and motor temperatures directly from the EV's CAN-bus.
