Professional RF Detector NI-S3000+ with AOA+Interferometric Technology for Accurate UAV Tracking

We're looking at the NI-S3000+ and its siblings SC-S3000, S5000, and S8000 — passive RF detection gear that listens rather than shouts, so no one knows you're watching.

Detection range varies by model form 3km to 8km, which is basically enough to cover a conference center or secure a perimeter before the drone gets close enough to be a real problem, and since it's passive, you're not broadcasting your position to every cheap quadcopter with a spectrum analyzer.

Frequency coverage from 70MHz to 6GHz catches most common control links and FPV video feeds, though you'll want to confirm it sees teh specific bands your threat profile uses because some niche long-range systems operate just outside that window.

Accuracy is within 3 degrees RMS at the antenna — that's tighter than most basic interferometric setups, and with the 360° horizontal plus vertical phased scanning you can track something climbing out of a valley or coming over a ridgeline. Power draw sits between 20W and 75W, so a small solar panel or battery pack keeps it running for days without grid power.

It's IP65 rated, which means rain and dust won't kill it, but don't submerge it — we've had buyers mount these on vehicles and fixed poles, and the LAN interface makes networking multiple units straightforward for triangulation of both the drone and the controller.

Anyway, MOQ is usually 2 units but our company can do a single if it's a demo or evaluation — lead time runs about 30 days or so, and we can provide COAs with raw sweep data if your compliance team needs to verify detection thresholds.
