Sentinel Cube – Compact Long-Life BLE Asset Tracker + Platform Access

The Sentinel Cube is a compact BLE tracking device engineered for discreet placement within vehicles, luggage, protective cases, operational kits, and portable high-value items. With a small 48 × 38 × 13.7 mm footprint and ruggedised construction, the Cube offers long-term, low-maintenance proximity intelligence while remaining nearly invisible in daily use. 
 
Powered by a 1100 mAh non-rechargeable battery, the Cube provides up to 30 months of continuous operation with no charging required. Throughout this period, it connects via BLE signals detectable through the global BLE crowdsourced detection method, allowing the device to be identified by nearby smartphones and BLE-enabled devices. This supports proximity-based awareness, last-seen location visibility, and movement insights without requiring GPS, SIM cards, or cellular infrastructure. 
 
The integrated audible buzzer enables rapid on-site asset recovery, helping users locate items in vehicles, storerooms, offices, or cluttered environments. 
 
Platform access is included for 30-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. 
 
After the original battery lifespan ends, users can replace the battery and maintain uninterrupted platform access by subscribing to a monthly Platform Access Plan at R10 per month, enabling continued digital oversight. 
 
Designed for discreet deployment and long-duration performance, the Sentinel Cube delivers reliable BLE-based proximity intelligence for personal, commercial, and security-focused applications.
