DD400-E Drone Detection System: Portable Full-Frequency Team Alerting
A Closer Look at Portable Drone Awareness
The DD400-E drone detection system gives mobile security teams a practical way to monitor nearby airspace. It combines a portable detection host with an information-receiving wristwatch. Therefore, personnel can receive alerts without remaining beside the main device. The system uses spectrum scanning, spectrum feature identification, signal detection algorithms, and drone identification algorithms. As a result, it can identify mainstream drones, quad-rotors, fixed-wing aircraft, FPV drones, and most DIY drones. In addition, its customizable scanning range extends from 70 MHz to 6.2 GHz. The default bands include 400 MHz, 800 MHz, 900 MHz, 1.2 GHz, 1.4 GHz, 2.4 GHz, 5.2 GHz, and 5.8 GHz. This broad coverage supports drone detection across multiple operating environments. Meanwhile, sound, light, and vibration alarms provide clear notification when a potential signal is detected. The 1+N team collaboration function can synchronize alerts across linked devices. The wristwatch adds a low-power ultra-wideband digital reception channel for mobile operators. Consequently, the DD400-E suits patrols, restricted airspace, sensitive sites, public events, and other situations where early warning and coordinated communication matter. Detection distance depends on visibility and the surrounding electromagnetic environment, so teams should evaluate local conditions before deployment.
Key Advantage
The host and wristwatch work together. Thus, mobile personnel can receive synchronized drone alerts while operating away from the main unit.

The specification graphic presents two field-portable components. The rugged black handheld host includes a vertical external high-efficiency ultra-wideband antenna, a color display, physical controls, and a segmented protective housing. By comparison, the wristwatch receiver has a rectangular display, side buttons, and an adjustable perforated strap. Both displays use blue-toned interfaces, which reinforce the system’s field-oriented design.
Full-Frequency Detection and FPV Early Warning
The DD400-E supports customized scanning throughout the 70 MHz to 6.2 GHz range. Moreover, its default frequency set covers eight listed bands. This gives operators a flexible starting point while allowing other bands to be customized. The system also emphasizes early warning for FPV drones. Consequently, teams may gain more time to assess a signal and follow their established response procedures.
- Identifies mainstream, quad-rotor, fixed-wing, FPV, and most DIY drones.
- Supports dual-mode detection for different operating requirements.
- Uses spectrum and drone-identification algorithms.
- Provides sound, light, and vibration notifications.
- Allows frequency-band customization within the stated range.
Aiming for Fewer Unnecessary Alerts
The product description highlights a low false-alarm rate. Therefore, the system is designed to help personnel focus on meaningful drone signals rather than excessive notifications.
1+N Team Collaboration in the Field
The 1+N collaboration feature links multiple devices into a coordinated monitoring network. When one unit identifies a possible drone signal, connected team members can receive synchronized alarms. Furthermore, the wristwatch reception distance is rated at least 500 meters in open, unobstructed conditions. This arrangement supports patrols, observation posts, access points, and distributed security teams.
Military and Law Enforcement
Security personnel can use shared warnings while protecting sensitive locations and high-security zones. In addition, synchronized alerts can improve communication between mobile team members.
Patrol and Surveillance
The portable host suits field patrols and mobile observation. Meanwhile, the wristwatch keeps alerts accessible when an operator is positioned away from the host.
Public Safety and Event Security
At public events and crowded venues, early drone detection can give security teams additional time to evaluate possible airspace concerns.
Why Choose the DD400-E?
The DD400-E brings together broad frequency coverage, FPV early warning, portable hardware, and team synchronization. As a result, it offers a focused solution for organizations that need mobile drone awareness and rapid notification.
