How It Works with Net Domain Technologies
The VT-330 sends GNSS position data and vehicle telemetry over GSM/GPRS to Net Domain Technologies, enabling live maps, alerts and historical reports. Dual SIM support reduces data drops by allowing the device to switch between carriers; Net Domain Technologies receives continuous location and event updates for efficient fleet oversight and anti-theft workflows.
- Real-time location and telemetry updates via GSM/GPRS to Net Domain Technologies for live tracking and route playback.
- SOS button events are delivered to Net Domain Technologies so operators can trigger immediate responses.
- Digital inputs can report door, ignition or alarm status to Net Domain Technologies when wired to vehicle signals.
- Remote immobilizer control via the included relay/output — Net Domain Technologies can initiate immobilization when configured with vehicle wiring and platform permissions.
- Note on Bluetooth sensors: the VT-330 specification does not list Bluetooth; Net Domain Technologies can also accept Bluetooth sensor data from compatible trackers where available.
