Backed by support from DJI, the world’s foremost drone manufacturer, the V-Line Pro seamlessly integrates with DJI’s newly launched enterprise-grade drone, the M400. Tailored for rugged environments and advanced payload management, this system takes the utility of the M400 to soaring new heights—quite literally.
Unleashing the Full Potential of the DJI M400
DJI’s Matrice 400 is the latest addition to its suite of commercial-grade aerial solutions. Designed to support up to seven simultaneous payloads, it’s built to handle complex tasks ranging from thermal imaging and LiDAR mapping to communications relays and multi-angle video surveillance.
But while the M400 has earned praise for its modular design and versatility, flight endurance often remains a limiting factor for drone missions—especially in operations such as emergency response, surveillance, and environmental monitoring. This is where Volarious’ V-Line Pro enters the picture.
"We developed the V-Line Pro with the vision of maximizing aerial uptime," stated Weiliang, CEO of Volarious. "Our tether system significantly reduces the need for battery swaps and enables continuous payload operation. With power supplied directly from the ground, pilots can focus on completing missions without interruptions."
V-Line Pro: The Technology Behind the Tether
At the heart of the V-Line Pro is a lightweight, aviation-grade tethering cable capable of extending up to 70 meters into the sky. The cable has been meticulously designed to be both durable and flexible, providing reliable power flow while maintaining resilience in outdoor conditions.
Equipped with a smart tension system, the V-Line Pro automatically adjusts cable slack to account for wind resistance and aerial dynamics. This not only ensures safety but also allows a single operator to deploy and manage the system with ease. The motorized reel delivers ascent and descent speeds of up to 7 meters per second, enabling quick redeployments with minimal downtime.
Crucially, the tether system can be powered by a variety of field-ready battery stations, including the DJI Power 1000, giving operators flexibility based on their specific mission profiles and logistics.
Enhanced Safety Through Thermal and Height Control
Volarious placed considerable emphasis on safety when designing the V-Line Pro, recognizing that both mission success and operator confidence rely on system stability and reliability.
One standout feature is the Advanced Thermal Control system. This internal monitoring unit uses six temperature sensors and nine strategically placed fans to regulate thermal conditions across the tether management system. Whether deployed in high-temperature zones or extended operations, this thermal oversight prevents potential overheating and ensures continuous operation under demanding workloads.
Another notable safety element is the Auto Limit Height system, which prevents the tether from overextension. The M400 drone and V-Line Pro engage in constant communication, and when the system detects the maximum cable length has been reached, it automatically halts ascent. This not only safeguards the tether cable from excessive stress but also protects the drone from altitude-related complications.
Integrated with DJI Pilot 2 for Seamless Control
Ease of operation is another cornerstone of the V-Line Pro’s design. Pilots using DJI’s Pilot 2 app will find an integrated widget that appears automatically when the V-Line Pro is connected. Through this interface, users can access real-time tether parameters, such as cable tension, power status, and system temperature.
By embedding these features into the Pilot 2 environment, DJI and Volarious eliminate the need for separate dashboards or complicated configurations, making flight operations smoother and more intuitive.
Built for Mission-Critical Applications
The pairing of the DJI M400 and V-Line Pro opens new possibilities for industries that depend on long-duration, high-stability aerial surveillance.
Firefighting units can deploy drones to monitor active wildfires or hotspots for extended periods without needing to rotate batteries mid-flight.
Search and rescue teams can maintain overhead situational awareness in disaster zones without losing precious time.
Security and defense operators can perform continuous surveillance or communications relay missions from a fixed aerial vantage point.
Broadcast teams can use the tethered M400 setup as a stable aerial cam, eliminating the risks of running out of battery during live coverage.
With drones increasingly viewed as critical tools across industries, tethered systems like the V-Line Pro are redefining how aerial operations are planned and executed.
For professionals considering tethered flight solutions, the DJI M400 offers unmatched compatibility and performance. If you're exploring DJI's broader lineup, you can browse available DJI drone models on Amazon for more options that suit your specific needs.
Volarious: Pioneering Tethered Drone Innovation
Volarious is no newcomer to the world of tethered drone systems. Based in Singapore, the company has built its reputation on developing mission-specific aerial hardware and software that cater to the unique demands of enterprise drone operators. With a portfolio that spans tethering systems, energy solutions, and software integrations, Volarious continues to demonstrate a commitment to innovation, security, and operational efficiency.
“We want to empower professionals in high-stakes fields,” Weiliang commented. “By working closely with DJI and aligning with their engineering standards, we’ve created a product that matches the robustness and capability of the M400 platform.”
A Glimpse Into the Future of Aerial Operations
As drone technology evolves, the demand for long-endurance, high-reliability flight systems is increasing. While battery technology has made remarkable strides in recent years, tethered power solutions are carving out a distinct niche—especially in situations where safety, compliance, and extended coverage are paramount.
The launch of the V-Line Pro signals a major step toward mature, scalable drone deployments that don’t depend on battery limits or multiple flight cycles. It also reflects a broader industry trend: pushing drone systems beyond their conventional roles and transforming them into persistent aerial platforms.
Conclusion
With the V-Line Pro, Volarious has not only extended the capabilities of the DJI M400 but also reimagined what’s possible in drone-supported operations. Offering a powerful mix of energy efficiency, safety, and operational control, the tether system empowers professionals across sectors to tackle complex challenges with greater confidence and clarity.
As industries explore new frontiers in data collection, surveillance, and real-time aerial insights, partnerships like that of DJI and Volarious may well define the next chapter of enterprise drone innovation.DJI
