Supplier's note

  1. Technical Breakthroughs:

    • Accelerometer Integration: Enables motion-triggered alerts (e.g., vibrating when keys are moved out of range).
    • Extended Battery Life: The Pro model’s 24-month battery outperforms industry averages by 30%.
    • Enterprise API Access: Allows seamless integration with asset management systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for personal use (e.g., tracking keys or wallets).
    • Advanced Model: Suitable for frequent travelers or small businesses needing IPX7 water resistance and longer range.
    • Pro Model: Best for enterprise asset tracking or outdoor use, with IP68 rating and API compatibility.

With the Pro Model’s 100-meter range and triple the battery life of competitors, it ensures reliable tracking in large facilities. Pair its accelerometer with the app’s geofencing to automate alerts when items enter/exceed predefined zones.
