BN-303G
The BN-303G is a compact vehicle-mounted GPS tracker engineered for reliable real-time tracking and robust anti-theft protection. Designed for concealed installation on cars and commercial vehicles, this Plaspy compatible tracker delivers high-precision GNSS positioning and flexible telematics data transport so fleet managers, rental operators, and private owners can monitor location, ignition state, alarms and basic telemetry in real time.
The BN-303G supports quad-band 2G GSM/GPRS communications and integrates seamlessly with standard tracking platforms such as Plaspy, offering TCP/UDP and SMS transport options. With a rechargeable backup battery, intelligent power-saving “smart mode,” and a wide set of alarms (SOS, overspeed, geo-fence, door open and more), the BN-303G is a practical choice for fleet management, anti-theft defense, and vehicle monitoring projects that require dependable telemetry and easy platform integration.
Key Highlights
- Plaspy compatible GPS tracker optimized for vehicle-mounted real-time tracking and anti-theft monitoring.
- High-sensitivity GNSS receiver (–165 dBm) with typical positioning accuracy around 5 meters for reliable location data.
- Quad-band 2G GSM/GPRS (850/900/1800/1900 MHz) with TCP, UDP and SMS transport for flexible back-end integration.
- Intelligent “smart mode” conserves power while parked and wakes on movement or predefined alarms.
- Comprehensive alarm suite: SOS, movement/shock, overspeed, geo-fence, door open, low battery and external power disconnection.
- Vehicle power operation (12–24V) plus internal 3.7V 300mAh rechargeable battery for backup and settings preservation.
- Remote telecommands including remote voice listening, one-way call and remote fuel/power cutoff (immobilizer-style control).
How It Works with Plaspy
When integrated with Plaspy, the BN-303G streams location and event data to the platform using TCP, UDP or SMS, enabling live tracking, alerting, and historical reports. Plaspy ingests the device’s telemetry and alarm messages to provide a unified dashboard for fleet management, anti-theft response and operational analytics. Installation is straightforward: the unit connects to vehicle power and uses its internal GNSS receiver to generate precise location fixes that Plaspy displays on maps and in reports.
- Real-time location and telemetry updates delivered over TCP/UDP or SMS to Plaspy.
- Ignition (ACC) state notifications and door/open alarms for event-driven workflows.
- Optional fuel monitoring integration (requires external fuel sensor) for fuel tracking and anomaly detection.
- Remote immobilizer-style control via remote fuel/power cutoff to support anti-theft response.
- Integrates into the Plaspy ecosystem alongside Bluetooth sensors and other telematics devices commonly used in fleet deployments.
