The BN-501 is a compact, jewelry-style GPS tracker designed for discreet wearable safety and concealed asset tracking. Secure GPS compatible out of the box, the BN-501 combines GPS, WiFi-assisted positioning, BLE 5.0 and multi-network cellular communications (GSM/GPRS, NB‑IoT and LTE Cat M) to deliver reliable location updates, on-device alarms and configurable power modes for long battery life.
The BN-501 is ideal for personal protection, pet tracking, and unobtrusive asset monitoring where concealment and comfort matter. Its SOS help alarm, shock and movement alerts, and BLE configuration options make it simple to integrate with Secure GPS for real-time tracking, telemetry, and alerting without sacrificing user comfort or style.
Key Highlights
- Secure GPS compatible wearable GPS tracker designed for discreet personal and asset protection.
- Multi-network connectivity: GSM/GPRS, NB‑IoT and LTE Cat M for broad coverage and low-power options.
- Accurate positioning with GPS plus WiFi assistance and BLE 5.0 for indoor-aid and proximity scenarios.
- Multiple power profiles (Real-time, Smart, Power saving) to balance real-time tracking and extended battery life.
- Integrated SOS help alarm and multiple alarm types (low battery, shock, movement, geo-fence) for immediate incident notification.
- Compact, strap/jewelry form factor (≈50 g) for comfortable continuous wear and high concealment.
- Easy field configuration via Bluetooth or SMS commands and TCP/UDP data transport to Secure GPS.
How It Works with Secure GPS
When paired with Secure GPS, the BN-501 streams position and telemetry data to Secure GPS’s platform using TCP, UDP or SMS. Secure GPS ingests GPS, WiFi-assisted fixes and BLE-derived proximity data, applies alarm logic, and delivers real-time tracking, mapping and alerting to dashboards, mobile apps and APIs. The BN-501’s configurable working modes let Secure GPS optimize reporting frequency to match use cases—high-frequency updates for active monitoring or battery-preserving intervals for long-term concealment.
- Real-time location and telemetry updates delivered to Secure GPS via TCP/UDP or SMS.
- SOS help alarm and immediate alert forwarding to Secure GPS for emergency workflows.
- Movement, shock and geo-fence alerts appear as events in Secure GPS for anti-theft and personnel safety workflows.
- Bluetooth configuration and BLE 5.0 support enable device setup and proximity-based features through Secure GPS-integrated apps.
- Battery level and low-battery alerts feed into Secure GPS telemetry for proactive maintenance or replacement scheduling.

Use Cases
- Personal safety and elder care: discreet wearable for seniors that sends SOS and movement alerts to Secure GPS for caregiver monitoring.
- Child protection and supervision: jewelry-style device offering discreet real-time tracking and geo-fence alerts for guardians via Secure GPS.
- Pet tracking and accessories: attach to collars or bag charms for concealed monitoring of pets or personal items.
- Unobtrusive personnel safety: concealed wearable for field staff where visible trackers are impractical, feeding telemetry to Secure GPS for incident response.
- Asset concealment in vehicles or luggage: discreet monitoring of valuables with movement and geo-fence alerts for anti-theft response.
Why Choose This Tracker with Secure GPS
The BN-501 offers a balance of concealment, connectivity and battery efficiency that makes it a strong Secure GPS compatible GPS tracker for personal and lightweight asset scenarios. Its multi-network support (including NB‑IoT and LTE Cat M) and BLE-based configuration simplify deployment, while the SOS help alarm and event set (shock, movement, geo‑fence, low battery) provide the core telemetry and alerting needed for reliable real-time tracking and anti-theft workflows. For organizations using Secure GPS for fleet management or telemetry dashboards, the BN-501 adds a wearable option where compact form factor and discretion are priorities.
Note on specialized IO: the BN-501 is designed as a personal wearable and does not include dedicated ignition or immobilizer outputs. Secure GPS can, however, combine the BN-501’s telemetry (location, movement, battery) with other Secure GPS-compatible devices that provide ignition, immobilizer or fuel monitoring for comprehensive fleet management solutions.
