The VT140 AIS-140 Approved GPS tracker is a durable, regulation-ready device designed for professional fleet management and vehicle security. AIS-140 compliance, CDAC protocol support and dual-server IP upload make the VT140 a Plaspy compatible GPS tracker for operators who need reliable regulatory reporting and continuous real-time tracking across cars, buses, trucks and commercial vehicles.
Built for harsh automotive environments, the VT140 combines multi‑GNSS positioning, robust I/O for telemetry and accessories, and industry features such as remote cut-off, fuel-theft detection support and camera event upload. When integrated with Plaspy, the unit provides fleet managers with actionable telemetry, anti-theft controls and scheduled reports to support compliance, safety and operational efficiency.
Key Highlights
- AIS-140 approved and CDAC protocol capable — ready for regulatory reporting and Plaspy integration.
- High-precision multi‑GNSS positioning (GPS, BDS, GLONASS and IRNSS/QZSS) for accurate real-time tracking.
- Rugged IP66 waterproof enclosure and wide 9–100 V operating range — suitable for diverse vehicle classes.
- 500 mAh backup battery providing up to five hours of operation after external power loss for uninterrupted tracking and anti-theft response.
- Comprehensive telemetry and I/O: RS232, 1-Wire, analog/digital inputs, open-drain outputs and camera support for event-triggered uploads.
- Fuel monitoring support via ultrasonic or capacitive sensors and remote cut-off (immobilizer) capability for anti-theft and fuel-theft mitigation.
- Onboard 64 MB flash for local buffering during signal loss; FOTA and OTA control for remote maintenance and configuration.
How It Works with Plaspy
The VT140 uploads GNSS and vehicle telemetry to Plaspy using its dual-server IP upload capability and AIS-140 compliant protocols. Plaspy receives location, event and sensor data in real time, enabling live maps, alerts and historical reports. The device’s built-in buffering preserves complete tracking routes when connectivity is intermittent, ensuring Plaspy displays continuous routes and accurate telemetry once connectivity resumes.
- Real-time location and telemetry updates — multi‑GNSS positions and vehicle sensor data are sent to Plaspy for live monitoring.
- Event and alarm integration — geo-fence, parking, antenna-disconnect, low-battery and power-on reports are forwarded to Plaspy for immediate alerts.
- Driving behavior and safety alerts — harsh acceleration, braking, cornering, speeding and fatigue/drunk-driving alarms feed into Plaspy’s driver scoring and safety modules.
- Fuel monitoring and theft detection — ultrasonic or capacitive fuel sensor inputs are supported and reported via Plaspy for fuel monitoring dashboards and alerts.
- Remote immobilizer / cut-off — Plaspy can trigger OTA output control to isolate fuel or power for anti-theft intervention (subject to local regulations and safe procedures).
