DR400-D
Portable FPV Drone Detection & Video Capture Device
The DR400-D is a portable FPV detection and analog video capture device that combines full-band RF detection, FPV image interception, and on-board video storage in one compact unit. It helps frontline teams quickly find, see, and record FPV and DIY drone activities for real-time response and post-event evidence.
Our handheld drone detection scanner is a portable RF drone signal detector and personal drone detection device that equips frontline teams with an on-person drone situational awareness tool and a dependable carry-on drone monitoring system with integrated FPV video interception capability. It functions as a hand-carried RF detection device and portable drone signal scanner, providing close-proximity drone detection through a human-portable RF sensing tool and a tactical personal drone alert system.
Designed for patrol officer operations, it includes a silent passive drone detection unit, a real-time handheld drone alert tool, a body-worn RF detection receiver, and a low-altitude drone awareness device that enhance responsiveness in fast-changing environments. As a frontline drone detection tool, it incorporates an operator-held RF signal monitor, a compact drone detection module, and a non-jamming portable detection tool that serves as an RF-based drone proximity detector.
The system leverages handheld passive RF signal acquisition, a wideband drone RF scanning receiver, and a tactical SIGINT handheld detector combined with an AI-assisted drone signal analysis module. With multi-band personal RF monitoring, an RF pattern recognition handheld platform, close-range UAV RF signature detection, and an operator-level drone awareness engine, it delivers accurate detection, FPV feed interception, and reliable monitoring for real-world field missions.
what makes us different
Key Benefits
Full-band FPV & control-link detection
Detects drone signals across 70 MHz–6.2 GHz, covering mainstream control, telemetry and FPV video bands for DJI, Autel, Hubsan, FPV racing and DIY drones.
Real-time FPV video interception & recording
Captures analog FPV video in the 500 MHz–6 GHz range, allowing operators to see the intruder’s first-person view and store footage to an SD card for evidence
Field-proven detection range
Provides up to ≥1.5 km detection and video capture radius in line-of-sight, clean RF environments, supporting early warning and situational awareness around critical sites.
Lightweight, single-operator design
Weighing ≤1.2 kg with a 7-inch touchscreen, built-in battery and shoulder/wrist options, DR400-D is optimized for mobile patrol and rapid deployment.
Team collaboration ready (1+N mode)
Supports a master–slave architecture with optional wrist receiver, enabling alarm linkage and team coordination during complex operations.
Intuitive touchscreen interface & quick setup
A 7-inch touchscreen, clear signal lists and simple mode switching let operators start scanning, lock onto FPV video, and begin recording within seconds — reducing training time and speeding up every deployment.

How DR400-D Works (Operation Workflow)
How It Works
01 Deploy & Power On
Remove the device from its case, install the three antennas (full-band capture, 5.8 GHz antenna, and full-band detection antenna), and turn on the power knob.
02 Scan & Detect
The DR400-D continuously scans the configured frequency bands. When drone or FPV signals are detected, they are displayed in the UI with frequency, signal type and strength, while alarms can notify the operator.
03 View FPV Video
When FPV-type signals are found, the operator taps the FPV icon to open the image capture interface, fine-tune the frequency, and see the intruder’s first-person view in real time.
04 Record & Export
Enable DVR, start recording, and save evidence to the SD card for later review and extraction via card reader or USB.
