Sentinel Node – Ultra-Compact BLE Air-Tag + Platform Access

The Sentinel Node is a compact, energy-efficient BLE micro-tracking module engineered to deliver persistent proximity intelligence across the Sentinel ecosystem. Designed as an embedded component, the Node is integrated into multiple Sentinel solutions, to enable pro-active digital oversight in both personal and professional environments. 
 
Using the global BLE crowdsourced detection method, the Sentinel Node allows supported devices to be detected by nearby smartphones and BLE-enabled devices in urban, suburban, and high-traffic areas. This provides broad detection coverage without GPS, SIM cards, Wi-Fi, or cellular connectivity, making the Node ideal for covert, low-profile, and power-efficient tracking applications. 
 
With its ultra-small footprint, low power consumption, and highly configurable broadcast parameters, the Sentinel Node can be integrated into a wide range of applications and form factors. This flexibility enables deployment across Sentinel’s solution-driven product ecosystem, including our dedicated pet range of collars, specialised keyring housings, luggage holders, magnetic holders, and other purpose-built enclosures designed to support specific operational and lifestyle tracking requirements. As the core proximity broadcast component across these platforms, the Node serves as the technological foundation for proximity-based intelligence throughout the broader Sentinel ecosystem.
 
Platform access is included for 12-months. During this time, users benefit from proactive digital oversight, including geofence alerts, movement notifications, BLE detection logs, event history, and device-health monitoring. Unlike reactive consumer tools such as Apple “Find My” or Google “Find My Device,” which provide only last-known location after loss, the Sentinel Platform offers pro-active monitoring and real-time alerting to prevent loss before it occurs.
