Ⅰ. Product Overview
The DR400-A is a portable UAV detection system built on RF spectrum-sensing technology. It integrates detection, indication and control in a single unit. Using a proprietary, low-power digital receiver, advanced signal-detection algorithms and a dedicated UAV identification engine, together with an ultra-wideband external antenna, the device delivers an extremely low false-alarm rate even in complex electromagnetic environments. It accurately recognises multi-rotor, fixed-wing, DIY and FPV drones and immediately issues audio, visual and vibration alerts, making it an ideal solution for security, patrol and area-protection missions.
Ⅱ. Key Features & Selling Points
1. Dual-Mode Detection
Selling point: Two detection modes can be switched on the fly to match the scene and mission, balancing coverage and accuracy and improving adaptability in challenging RF conditions.
2. Full-Band Coverage
Selling point: Customisable sweep from 70 MHz to 6.2 GHz guarantees complete surveillance of all mainstream and newly released drones with no blind spots.
3. FPV Super-Early-Warning
Selling point: Unique base-band signal analysis enables rapid, reliable early warning of DIY and FPV drones that are normally difficult to detect.
4. Ultra-Low False-Alarm Rate
Selling point: Advanced signal-processing filters out environmental EMI, maintaining high detection reliability in urban and other cluttered RF scenarios.
5. Portable & Long Endurance
Selling point: Compact, all-in-one design with hot-swappable Li-ion battery provides more than six hours of continuous operation for extended field missions.
