DR400-D Handheld Drone Detection Scanner
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.
- Handheld
- Patrol
What it does
7-inch handheld RF scanner with FPV analogue video capture and vibration, sound and light alarms.
FPV analogue coverage
Detection of all analogue video links from 500 MHz to 6 GHz.
Video capture and storage
Intercepts analogue video in real time and stores it on the memory card as evidence.
Sound, light and vibration alarms
Alerts the operator without needing to watch the screen.
Team mode
1+N master-slave design for alarm linkage; a wrist receiver is optional.

FAQ
DR400-D: frequently asked questions
What is the DR400-D?
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.
What is the detection range of the DR400-D?
The detection radius and the video capture distance are both 1.5 km or more, in line of sight with a clean electromagnetic environment.
Can the DR400-D record FPV video as evidence?
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.
How does the DR400-D alert the operator?
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.
Can several DR400-D units work as a team?
Yes. A 1+N master-slave design links alarms between units, and a wrist-worn receiver is available as an option.
