The NR008 is a robust automobile GPS tracker designed for Green-Gps compatible deployments that need reliable real-time tracking and vehicle control. Built around a SiRFstar GNSS chipset and SIMCOM GSM/GPRS communications, the NR008 delivers continuous position updates, real-time alerts and remote control functions that integrate smoothly into Green-Gps-based fleet management and telematics workflows.
The NR008 is ideal for businesses and individuals requiring anti-theft protection, remote immobilization and in-vehicle voice monitoring. With SOS alerts, geo-fencing, over-speed alarms and movement detection, this GPS tracker provides the telemetry and control features fleet managers expect while remaining straightforward to integrate with Green-Gps via SMS or GPRS.
Key Highlights
- Green-Gps compatible GPS tracker for reliable real-time tracking and fleet management.
- Remote immobilizer and engine control (fuel shutoff via SMS/GPRS) for anti-theft response.
- SOS emergency alerts and voice monitoring—authorized numbers can call the device to listen inside the vehicle.
- Geo-fencing and movement alerts to detect unauthorized routes or tampering, including anti-dismantle alarm on power loss.
- Over-speed alarms sent to the server and authorized mobile numbers to enforce safety and compliance.
- Packaged with practical accessories (SOS button, microphone, GPS antenna, connection cable) for fast in-vehicle installation.
- SiRFstar GPS and SIMCOM GSM module combination provides dependable GNSS fixes and cellular connectivity for telemetry delivery.
How It Works with Green-Gps
When integrated with Green-Gps, the NR008 transmits location and event data to the Green-Gps platform over GSM/GPRS or via SMS. Green-Gps ingests that data to provide map-based real-time tracking, alerting, and historical reports. Fleet managers can issue remote commands (for example, to immobilize a vehicle) through Green-Gps using SMS or GPRS command channels supported by the NR008.
- Real-time location and telemetry updates delivered to Green-Gps via GPRS or SMS.
- Geo-fence boundary alerts and movement detection trigger immediate notifications in Green-Gps.
- SOS emergency alerts forwarded to Green-Gps and authorized contacts for rapid response.
- Remote immobilizer/engine control through Green-Gps-issued SMS/GPRS commands to perform fuel shutoff when supported by vehicle wiring.
- Voice monitoring (call-in listening) and anti-dismantle alarm notifications are relayed to Green-Gps-enabled alert channels.
- Green-Gps can also coordinate telemetry and reporting workflows alongside other peripherals; if your deployment uses Bluetooth sensors, Green-Gps can aggregate those readings alongside NR008 data when paired with compatible hardware.
