Tethered system for DJI Matrice 400 and Matrice 4 drones: what it is, how it works, and why it is an operational revolution
The field of enterprise drones is evolving rapidly, especially for long-duration professional applications and in critical scenarios. Among the most innovative solutions are the DJI Matrice 400 and Matrice 4 tethered drone systems, which transform a UAV into an aerial platform with unlimited range.
Using a ground-connected power cable, the drone can stay airborne for hours (or even days), maintaining power and data connection at all times. This opens the way for strategic uses in public safety, infrastructure monitoring and emergency management.
But what is a tethered system? How does it work? And why is it so useful for DJI enterprise drones?
What is a tethered system for drones
A tethered system is a system that connects the drone to a ground station via a fiber cable and power supply. This cable, which is lightweight and ultra-durable, has a dual function:
Provides continuous power → the drone no longer depends on on-board batteries.
Transmits data in real time → ensures a stable and secure connection with the operator.
The result? The drone becomes a persistent aerial platform, capable of remaining suspended for long periods without interruption, in total safety.
Why use a tethered system on DJI Matrice 400 and Matrice 4
The DJI Matrice 400 and Matrice 4 series are already drones designed for professional missions. With the integration of a tethered system, the advantages become enormous:
Unlimited autonomy: ability to operate for hours or days.
Increased safety: the cable ensures continuous power and control.
Stable connection: low latency data transmission without risk of radio interference.
Resistance to complex scenarios: ideal for missions in dense urban environments or critical areas.
In summary: the tethered system eliminates the biggest limitation of drones, which is range.
Operational advantages of tethered technology
Mounting a tethered system on a DJI Matrice 400 or 4 drone means turning it into an always-on aerial surveillance platform.
The main advantages are:
Extended autonomy: no need for battery changes or mission interruptions.
Continuous H24 operations: ideal for long-term monitoring (events, borders, infrastructure).
Reduced logistics costs: fewer staff and less equipment to handle reloads.
Increased safety in flight: the cable also acts as an anchor, reducing the risk of losing the drone.
Secure data transmission: communications via fiber, less vulnerable to interference and attacks.
Practical applications of tethered systems
The applications are numerous, especially in settings where constant and continuous monitoring is needed:
Public safety and major events
Persistent aerial control over concerts, stadiums, events.
Monitoring flows of people in real time.
Law enforcement and defense
Surveillance of borders and sensitive areas.
Support tactical operations with constant aerial eye.
Civil defense and critical infrastructure
Surveillance of power plants, ports, airports.
Continuous monitoring of dams, bridges, industrial plants.
Emergencies and natural disasters
Constant aerial observation of affected areas.
Support in rescue operations and crisis management.

Legal and regulatory aspects
Unlike other more controversial technologies, tethered systems have no particular legal restrictions:
They are operational support devices, so they can also be used by private companies.
However, ENAC and EASA flight regulations (line of sight, authorized airspace, maximum altitudes) must be followed.
Missions must be planned with public safety in mind.
👉 In summary: Tethered systems are legal and usable by government agencies, companies, and certified operators.
