Our tethered drone solutions are critical asset for security operations. The continuous and global aerial view enables long, risk-free and efficient surveillance for both night and day use.

Using tethered drones as virtual ‘Surveillance Towers’ is a simple and efficient solution for semi-persistent applications, with a serious cost advantage over helicopters or manned aircraft. Tethered UAVs can be deployed for long-term operations in order to cover a large area for several hours. Compact, lightweight and quick to deploy for a single operator, tethered UAVs make little noise from a high position, ensuring discreet surveillance.

Our tethered systems are best suited for police forces, public safety operations, firefighting, crisis monitoring or military operations.



  Powered from the ground through our patented micro-tether, connected drones are able to fly for hours, allowing long duration surveillance operations, for day and night missions.


  Thanks to the micro-tether, communications are unjammable, immune to interferences and enable real-time high-speed data transmission.


  Robust and easily transportable, our tethered systems are designed for the field. Quick to use and deploy, it is the simplest and most effective solution for persistent aerial surveillance.


  • Police operations
  • Facility and asset protection
  • Emergency First Responder situational awareness
  • Firefighting
  • Special Operations Police Forces situational awareness
  • Border surveillance
  • Crowd control
  • Harbour observation



    Due to an increasing number of vehicles on roadways, better traffic management and planning have become imperative.

Our tethered solutions offer continuous and real-time aerial video-stream, allowing persistant data collection and analysis. A tethered drone is a compact tool, easy to transport and deploy, that gives access to various valuable traffic data (trajectories, behaviors, vehicle types etc…), which are crucial information for individual end user (drivers), networks and transport operators or public authorities, to answer mobility challenges.

Count, measure and analyse in order to understand road-user behaviour, analyse trajectories and detec anomalies. With the deployment of a single UAV during several hours, continuously, get a more comprehensive look at traffic nodes.

Unlimited valuable data

These persistent aerial platforms provide real-time information over long durations. Persistent aerial video-streams offer access to valuable data: trajectories, type of vehicles, behaviors…

Wide coverage and discrete operations

Our tethered systems offer a wide coverage of traffic areas, enabling data collection and real-time monitoring. The small size of UAVs and the flight height (100m) prevent the driver’s behaviors to be affected.

Quick deployment

Our tethered systems are easily deployable, therefore allowing a better efficiency during traffic monitoring operations.


  • Enhancement of daily traffic, freeway conditions and road safety
  • Response to traffic congestion and car accidents
  • Sampling of vehicle speed
  • Automatic trajectory extraction and analysis
  • Estimations of OD flows
  • Analysis of vehicle types
  • Optimization of car park utilization



   Tethered UAVs are powerful tools for telecommunications, acting as airborne antennas. They enable the creation of temporary, wide-range networks: cellular, wifi, high-frequency radio and 3G/4G signals.

Thanks to their high-speed data transfer, our tethered systems are particularly suited for pop-up telecommunications.

They have many applications, such as emergency situations, crisis monitoring, firefighting, large events coverage and humanitarian missions.


Unlimited hovering

Our tethered systems grant unlimited autonomy, as they power the drone from a ground source. It enables the easy creation of temporary telecommunications antennas and networks for hours or days.

High-speed data transfer

Data transfer is a primary concern when using telecommunication devices. Our micro-tether technology allows secured communications, thanks to a physical link, at a high-speed rate.

Cost and time effective

Tethered drones represent a cost advantage compared to expensive towers. They are also easy to set up and use, which allow a better time response in case of emergency communications establishment.


  • Emergency management, on-demand network
  • Temporary ad-hoc networks
  • Cellular signal coverage
  • Emergency communications establishment
  • Connectivity (BTOB or BTOC) in remote areas



   Remote inspections of industrial structures and facilities are often costly, hazardous and sometimes impossible to achieve. While the fast growth of unmanned systems soutions is offering an answer, free-flying drones are still limited to a fraction of their potential in industrial maintenance, because of their limited flight time and their low safety level.

Elistair tethering solutions dramatically increase the safety of drone operations through a reliable power supply and secured communications. Immune to interference and scrambling, battery failures and fly-aways, our systems allow safe and efficient commercial inspections, in a variety of demanding industrial environments as airports, wind farms or refineries.

Operating in a volume of operation mastered by the micro-tether, industrial companies and drone operators now beneficiate from a full-control on their flights, facilitating the maintenance and the protection of their assets.

With our tethered systems, drone inspections are safer: full-control on the drone volume of flight, safe communications and reliable power supply.

Time efficiency

Your tethered UAV will be able to fly for unlimited durations. Therefore, long inspection operations will be done faster, at a better cost.

Real-time 4K video streaming

The micro-tether technology allows high-quality continuous data collection, like 4K video-stream, enabling real-time data processing and analysis, or on-site expertise.


  • Wind power stations
  • Telecom Towers & Antennas
  • Airports
  • Oil refineries and drilling rigs
  • Energy infrastructures
  • Viaducts and dams inspection



    Perfectly suited for sports broadcasting, Elistair tethered systems provide a rich aerial perspective to live filming. Tethered UAVs can revolutionize the entertainment industry by allowing unlimited aerial coverage with high quality aerial live shots, and the best safety standards.

  Tethered UAVs are key assets for increasing your audience through immersive aerial filming on large outdoor events like concerts and sports competitions. By offering a safer and unlimited aerial video-stream to producers, our systems bring innovative and visually rich aerial perspectives to live productions.


4K video-streaming

Secured 4K aerial video-stream is made possible thanks to Elistair’s micro-tether. Our tethered systems allow continuous and interferences-proof high-quality video-stream.

Unlimited Aerial Filming

Our micro-tether technology, which provides unlimited power from the ground station, enables continuous streaming of the entire event.


In crowded entertainment events, safety is essential, as your tethered UAV is likely to operate near populated areas. Elistair tethered technologies ensure secure operations through a full-control system.
