Dronesurvey Asia is the Hong Kong and Macau Support Representative for Rosefinch Technology, maker of advanced tethered drone systems, suitable for most DJI drones and others. Rosefinch Technology is a leading provider of smart tethered systems for persistent unmanned aerial surveillance, monitoring, reconnaissance, and inspection. Tethered systems also provide additional security and safety for drone operations in highly sensitive locations like airports or over large crowd gatherings.
With Rosefinch powered tether systems, you can keep a drone in the air for hours or even days at a time. Rosefinch Tether systems provide power to the drone, a secure data link from drone to ground, and compatibility with a wide range of models.
The Rosefinch Advantage
Rosefinch tether units are deployed by armed forces, law enforcement, civil security, and private security in over 20 countries around the world. They are used for event protection, perimeter surveillance, border protection, radio communications, long-duration health monitoring, emergency communication, traffic management, environment inspections, scientific research and much more.
Rosefinch’s tether technology has a number of advantages over other tether products on the market: smaller size, lighter weight, very simple operation, along with high reliability and stability.
Powerful functions include cable auto reel in and out, keeping the correct tension at the drone ascends or descends, along with consistent and reliable voltage monitoring for the air module that powers the drone in place of the battery.
In short, this is a proven, practical, and cost-effective tethered UAV product range that comes in at at a lower price point than the competition.
