FlySpark Sentinel-X3 is a portable multi-band FPV drone signal detection system engineered for identifying and intercepting analog video transmissions used by FPV drones.
The device continuously scans across three primary drone communication bands — 1.2 GHz, 3.3 GHz, and 5.8 GHz — enabling operators to quickly detect active drone signals in the surrounding airspace.
Sentinel-X3 performs high-speed automatic RF scanning across a wide spectrum range and completes a full scan within 4–8 seconds. When a drone signal is detected, the system provides visual and audio alerts and allows operators to monitor intercepted video transmissions directly on the integrated display.
The device is designed for rapid deployment and requires no manual configuration. All scanning algorithms are pre-configured, allowing the unit to begin monitoring immediately after power-on.
FlySpark Sentinel-X3 is suitable for security operations, counter-drone monitoring, tactical surveillance, and electronic intelligence applications where early drone detection is critical.
