The increasingly easy access to mini/micro UAVs makes them a growing potential threat to national and commercial security. Easy to produce, cheap to buy, simple to fly, and hard to detect, commercially and non-commercially available drones are among the most quickly evolving technological threats to military and civilian interests. In the US, a commercial drone reportedly alarmed the Secret Service in March 2015 when the UAV flew too close to the President's golf resort.

AirWarden™ detects both the drone and the controller so you can find the pilot of known and unidentified drones and controllers.


AirWarden™ is able to locate drone fleets and their pilots. Even those that fly "hidden" between buildings, industrial plants or trees.


AirWarden™ is a fully legal, passive system that does not demodulate and decode signals.

Khepra offers this all-in-one solution for drone defense, whether mobile or for stationary 24/7 surveillance. DHS has awarded the AirWarden™ Drone Detection System with the Developmental Testing and Evaluation (DT&E) Designation under the Department of Homeland Security (DHS) SAFETY Act.

Detects in Seconds.
The AirWarden™ system detects Radio Frequencies (RF) in the environment and can detect potential drone and controllers in seconds. Once detected, the signal is analyzed and run through several filters to ensure that it is in fact a drone or controller signal, and to calculate its location.


Detects Both Known and Unidentified Drones

AirWarden™ can detect any drone that emits an RF signal. This includes popular, ready-to-fly consumer drones, commercial drones, custom “kit” or Do It Yourself (DIY) drones and even a swarm of tiny micro-drones. Because the system uses the physical signature of a signal to identify drones, it can detect both known and unidentified drones. This means that it will detect new drones on the market even if the system’s ‘drone library’ has not been updated.

Fully Legal System

If an RF detection solution “decodes” or “demodulates” the signal to extract the drone type, GPS coordinates or the “Return to Launch” GPS coordinates, it violates U.S. Federal Wiretapping laws. The AirWarden™ system is a passive system that uses physical characteristics of the signal to detect and locate. This means it is fully legal, and will not be affected when drone manufacturers start to encrypt the signal between their drones and controllers. In addition, decoding and demodulating signals takes more time than physical signal analysis. This means systems using this method take longer to detect and locate a device.

Detects in all Weather Conditions

Because AirWarden™ uses the physical signals from drones to detect and locate, it can operate in all weather conditions. It is unaffected by lighting, sound, rain, clouds, fog, background clutter (like leaves or trash being blown about by the wind), or line of site making it suitable for air, ground, and marine UAV detection.

Detection Range

The system’s detection range is equal to the connection range between a drone and a controller. This means that if a drone and controller can connect up to 1 km apart, AirWarden™ can detect at 1 km or slightly more. If a drone and controller can connect at 5 km, AirWarden™ can detect at 5 km or slightly more.

However, it’s important to note that the connection range of a drone and controller can vary greatly. A drone and controller that can connect at 5 km in a desert environment may only be able to connect at, say, 1km in an urban environments. This is because RF signals behave very differently in built up environments. It also means the drone can’t fly as far away from the controller in urban areas.

System Integration

The AirWarden™ open architecture allows communication to/from other systems such as your organization’s existing alarm monitoring or reporting system.

Single Sensor Type

The AirWarden™ system uses only one type of sensor. This means it has:

  • Lower maintenance
  • Fewer sensors required
  • Less points of failure
  • More system redundancy

This results in a lower total cost of ownership.

Mobile Sensor Options

While the typical installation consists of four or more fixed sensors, AirWarden™ offers several mobile options:

  • Single Sensor Trailer – This can be used to detect and evaluate drone threats at a facility before installing a full system
  • Multi-Trailer Network – Several trailer-based sensors can be networked to provide both detection and location
  • Marine Vessel Sensor – This can act as a standalone sensor or join a network of fixed or mobile sensors on land.
  • Mobile Vehicle Sensor – This can act as a standalone sensor or join a network of fixed or mobile sensors, either land or marine based.
