FPV drones – why the threat is different
Updated:
In short
An FPV drone is flown through goggles showing the drone's camera feed. It is often custom-built, very fast, has no factory geofencing and typically broadcasts no ID. Sensors that rely only on commercial drone protocols easily miss it – wideband RF detection and radar are needed.
What is FPV?
FPV (First Person View) comes from drone racing and action filming. The pilot sees the drone's camera feed in goggles and flies manually, with little or no stabilising automation. Many of these drones are assembled from components.
How it differs from a commercial camera drone
- No factory geofencing – nothing stops it entering restricted areas
- Usually no Remote ID, or an unreliable one → Remote ID
- Non-standard protocols – commercial "fingerprints" don't help
- Wide frequency range – control and video can run outside 2.4 and 5.8 GHz; wideband detectors and effectors therefore cover roughly 840–5850 MHz → Frequencies
- Speed – over 100 km/h is possible, drastically shortening reaction time
Lessons from the war in Ukraine
In the war, FPV drones became cheap, mass-produced devices. Two lessons matter for civilian drone protection too: frequencies and protocols change fast, and fibre-optic-controlled drones have appeared that emit no radio signal at all. A system bought today must be updatable and must not depend on a single detection principle.
What it means for detection design
- Wideband RF detection that recognises signal energy and characteristic video signals, not only known protocols
- Radar for non-emitting targets → Radar
- Shorter reaction time – automated alerts, a simple decision chain
- Update guarantees in the procurement contract
In civilian settings
Most FPV drones seen at events are filming official sport or show footage – whitelist them. An unidentifiable FPV drone, however, deserves a higher-priority alert than a commercial camera drone.
