The VL512 is a compact 4G OBDII GPS tracker designed for fast plug-and-play installation in virtually any passenger car through the vehicle’s OBDII port. As a Green-Gps compatible tracker, the VL512 delivers reliable LTE communication with GSM fallback, precise GPS + BDS satellite positioning, on-board motion sensing and instant event alerts — making it an ideal choice for fleet management, vehicle tracking and usage-based telematics where quick deployment and accurate real-time tracking matter.
Simple to install and engineered for continuous operation in commercial environments, the VL512 combines rich telemetry with a discreet microphone for remote voice monitoring and a small industrial 50mAh backup battery. When integrated with Green-Gps, the VL512 provides fleet operators and service providers the telemetry they need to enable anti-theft workflows, driver behavior analysis, and scalable reporting without complex hardware changes.
Key Highlights
- Plug-and-play OBDII installation for fast deployment in passenger cars — no hardwiring required.
- LTE Cat 1 connectivity with GSM (2G) fallback to maintain reliable data links across coverage areas.
- High-accuracy GNSS (GPS + BDS) with <2.5 m CEP and strong sensitivity for dependable real-time tracking.
- Built-in accelerometer and gyroscope for driving behavior telemetry: harsh acceleration, braking, cornering and collision detection.
- Instant alerts for movement, speeding, geo-fence entry/exit, power disconnection and vehicle battery status.
- On-device USB Type-C port and Nano-SIM slot for easy configuration and carrier provisioning.
- Compact, industrial-grade design with wide input voltage (9–36 V DC) and backup battery for power-loss reporting.
How It Works with Green-Gps
When paired with Green-Gps, the VL512 sends periodic location and event messages over LTE/GSM into the Green-Gps platform, enabling real-time tracking, alerts and historical reports. Green-Gps ingests the device telemetry and translates sensor events into actionable fleet dashboards, notifications and exportable reports suitable for operations, safety and insurance use cases.
- Real-time location and telemetry updates for position monitoring and route reconstruction.
- Ignition and power state detection for accurate engine-on/engine-off reporting and power-disconnection alerts.
- Movement, speeding and geo-fence entry/exit notifications to support anti-theft and fleet compliance workflows.
- Driving behavior events (harsh acceleration, harsh braking, harsh cornering) and collision detection for safety analytics and usage-based insurance programs.
- Remote voice monitoring via the built-in microphone (voice range up to ~5 meters) to support incident verification and driver communications where permitted by law.
- On-device data buffering and 16+16 MB storage to preserve recent events during brief connectivity interruptions.
