In this video, we demonstrate the KZ-40 fixed UAV RID detection terminal in action — a wide-band drone spectrum detector covering 400MHz–6GHz with a ≥3 km detection range. Watch how it identifies up to 30 concurrent drones, parses RID data in ≤200 ms, and displays real-time position, altitude, speed, and flight trajectories. We also walk through Ethernet and 4G/5G backhaul, OTA configuration, and IP66-rated 24/7 deployment for airports, power stations, and critical sites.
