Air Payload Drop Release Mechanism System air dropper for DJI M400

The DJI M400 4‑Hook air payload drop release System is an ultra‑light, multifunctional mechanism device designed for the DJI Matrice 400 series. Weighing only 180 g, it combines a four‑hooks airdrop mechanism, high‑visibility strobe warning lights, and multi‑mode sirens into a single compact unit, making it ideal for emergency response, public safety, inspection, and special operations.

Built on the DJI SkyPort V2 interface and deeply integrated with DJI Pilot 2, the system enables remote control and real‑time feedback directly from the ground station. With built‑in load detection and weighing capabilities, along with five‑color strobe lighting (red, green, blue, yellow, white), it significantly enhances mission safety, situational awareness, and operational efficiency—especially in complex or low‑light environments.

Features

1. Four‑Hook Airdrop System with Load Detection
   The module provides four independent mounting positions, allowing operators to carry and release multiple payloads in a single mission. Each hook position is monitored in real time, with its load status displayed directly in DJI Pilot 2, helping operators clearly understand whether each bay is loaded, released, or ready for deployment.
2. Integrated Weighing Module for Safer Missions
   An internal weighing module measures the payload on each hook and reports the weight back to the pilot interface. This real‑time load information supports safer flight planning, better weight distribution, and more precise control in scenarios such as material delivery, emergency supplies drops, or tactical airdrop operations.
3. High‑Visibility Multi‑Color Strobe Warning Lights
   The system features built‑in strobe lights supporting red, green, blue, yellow, and white. These high‑visibility warning lights can be used for aerial signaling, orientation marking, area indication, and safety alerts, greatly improving visual recognition during night flights, low‑visibility operations, or coordinated multi‑drone missions.
4. Multi‑Mode Siren for Audio Warning and Guidance
   Multiple alarm sound modes are integrated, including slow alarm, fast alarm, rescue alarm, patrol alarm, fire alarm, air‑raid alarm, and a customizable alarm mode. These sirens provide flexible audio warnings for a variety of use cases such as rescue coordination, law enforcement, evacuation guidance, perimeter warning, and scene control.
