RF detection · DR400-D
DR400-D is a portable FPV detection and video-capture device for patrols, critical-target protection, and individual and team operations. It scans 70 MHz to 6.2 GHz, identifies mainstream, FPV and DIY drones, and captures analogue FPV video for evidence.

7-inch handheld RF scanner with FPV analogue video capture and vibration, sound and light alarms.
Custom scanning across 70 MHz to 6.2 GHz; default bands 400 MHz, 800 MHz, 900 MHz, 1.2 GHz, 1.4 GHz, 2.4 GHz, 5.2 GHz and 5.8 GHz.
Detection of all analogue video links from 500 MHz to 6 GHz.
Intercepts analogue video in real time and stores it on the memory card as evidence.
Alerts the operator without needing to watch the screen.
1+N master-slave design for alarm linkage; a wrist receiver is optional.
Figures are taken from the DR400-D specification sheet (January 2026). Performance depends on site, target and environment.

FAQ
The DR400-D is a handheld RF drone detector with a 7-inch touchscreen. It scans 70 MHz to 6.2 GHz, identifies mainstream, FPV and DIY drones, and captures analogue FPV video for evidence. It weighs 1.2 kg or less.
The detection radius and the video capture distance are both 1.5 km or more, in line of sight with a clean electromagnetic environment.
Yes. It intercepts analogue FPV video in real time and stores it on a memory card of 32 GB or more, up to 256 GB.
By sound, vibration and light, so the operator does not need to watch the screen. Detection response time is 3 s or less with 8 bands and 5 s or less with 12 bands.
Yes. A 1+N master-slave design links alarms between units, and a wrist-worn receiver is available as an option.
