Developed & manufactured in Slovakia, EU

The independent European alternative to DJI AeroScope®

A passive drone detector, developed and manufactured in Slovakia, EU: it receives Remote ID and DroneID up to OcuSync 4+ and shows you where every drone is — and where its pilot is located. No forced updates — you control what gets deployed and when. No recurring subscriptions. Optionally fully air-gapped.

The 250-gram blind spot

AeroScope is discontinued and unsupported. Drone incidents at airports, prisons and stadiums keep climbing.

The official answer is Remote ID — but in the EU, drones under 250 g don't have to broadcast it, and DJI's entire sub-250 g lineup doesn't: Mini, Neo, Flip, Lito. To a Remote ID receiver, the most popular drones in the sky don't exist.

What they do broadcast is DJI DroneID. The DroneWard detector reads both — open Remote ID and DJI DroneID — and puts every drone, including the "invisible" ones, on your map with the pilot's position.

Detect. Locate. Act.

Detect

The sensor passively receives every Remote ID and DJI DroneID broadcast in range — encrypted included, up to OcuSync 4+. It transmits nothing, so it's silent, legal to operate, and invisible to the drone's operator.

Locate

Every detection appears live on your dashboard: aircraft type, position, flight path, home point — and the pilot's location.

Act

Alerts fire the moment anything enters your airspace, so your team moves on live coordinates — to the drone, or straight to the person flying it. Every track is logged as evidence.

Can't process the detection? It's not lost. The detector stores raw detection data on the device. If a drone broadcasts something the software can't parse yet, the packets are saved — and when a software update adds support, the device re-interprets the stored records. A drone it couldn't identify last month gets identified retroactively — on the update you chose to install, when you chose to install it. Raw records are kept as long as storage allows, typically a few months.

Demo video — 90 seconds, live detection with pilot localization

Built for the sites that can't have surprises overhead

Airports & heliports

Monitor approach paths and the airport perimeter for unauthorized drones, including sub-250 g models that don't broadcast Remote ID.

Energy & utilities

24/7 stationary monitoring of power plants, substations and pipelines. Suitable for nuclear sites.

Stadiums & public events

Portable unit for temporary deployments. Monitor the airspace over the venue and locate pilots in real time.

Critical infrastructure

Detect every drone over your site and locate its operator, around the clock. Stationary sensors cover the perimeter, run on your hardware, and can operate air-gapped.

Frequently asked questions

Talk to us. Then see it in action.

Book a short call — you'll talk directly with our CEO or CTO, not a sales team. We'll go through your situation, answer the technical questions, and agree on the next step.

If you're in Slovakia, Czechia, Poland, Hungary or Austria, that usually means we come to you and demonstrate the detector on your site, with a real drone in the air. Anywhere else, we'll figure out the best way together.

If it fits both of us, we'll put you on the list for the first units.
