Sentinel Stem – Concealed Handlebar Tracking Plug + Platform Access

The Sentinel Aura Stem is a compact, concealed BLE tracking device engineered for discreet long-term placement inside a bicycle handlebar or stem cavity. Designed to support theft prevention and recovery initiatives, the device operates using BLE proximity intelligence and global crowdsourced detection, enabling location awareness without requiring a SIM card or conventional cellular connectivity. 
 
Built for harsh conditions, the Aura Stem features a rugged enclosure with an IP66 environmental protection rating, supporting dependable performance across outdoor, high-vibration, and wet-weather applications. 
 
Powered by an internal 500mAh non-replaceable/disposable battery, the unit delivers an estimated service life of at least 2 years, providing operational consistency with minimal user maintenance. 
 
Platform access is included for 24-months. During this period, users gain proactive monitoring capabilities, including geofence alerts, movement notifications, BLE detection mapping, event history, and device-health visibility. This stands in contrast to reactive consumer tools such as Apple “Find My” or Google “Find My Device,” which rely solely on last-known location and user-initiated searches.
