DOCK 3 Tether SYSTEM - Autonomous BVLOS Persistent Surveillance System for DJI Matrice 4D / 4TD

The DOCK 3 Tether SYSTEM is an autonomous beyond visual line of sight persistent surveillance system designed for teams that need continuous aerial visibility without the limitations of standard battery-powered drone operations. Built around the DJI Dock 3 and compatible with the DJI Matrice 4D and Matrice 4TD, this tethered autonomous RPAS solution supports long-duration overwatch, autonomous patrol, remote monitoring, and persistent surveillance from fixed, mobile, or on-premise deployments.

By combining autonomous flight capabilities with a hardened tether power supply, the DOCK 3 Tether SYSTEM enables the aircraft to remain airborne for extended operations while receiving stable 310V DC power through a 50m tether cable. The Dock 3 manages autonomous launch, landing, charging, data relay, and remote mission execution, allowing teams to fly drones remotely from a dock and support BVLOS operations where approved.

Designed for public safety, security, infrastructure, industrial, and critical-site monitoring, the system gives operators a persistent aerial perspective with AI-enabled detection and counting functions, including people counting, vehicle counting, car counting, boat counting, and target tracking. Video feeds can be streamed through RTSP or RTMP for integration into existing surveillance systems, command centres, or on-premise security infrastructure.

The system is designed to reduce on-site pilot workload and support compliant autonomous RPAS operations, with remote mission management through DJI FlightHub 2. Operator certification, training, and approvals may vary by jurisdiction and mission type.

Operational Advantages

The DOCK 3 Tether SYSTEM supports autonomous flight and autonomous RPAS workflows while enabling persistent surveillance without frequent battery changes. By reducing the need for continuous manual piloting during long-duration monitoring, the system helps teams maintain reliable aerial visibility from a fixed dock, mobile platform, or on-premise installation. Live aerial video can be streamed to command centres and surveillance teams through RTSP or RTMP integration, helping improve situational awareness for public safety, security, and industrial operations. The system is also designed for scalable deployment across multiple sites or remote locations.
