A SENSOR THAT CAN HEAR WHAT YOU CANNOT SEE
The HARK sensor combines a high-precision microphone array
OUR TECHNOLOGY
Five integrated capabilities delivering passive, real-time acoustic detection across ground domains for defence and critical infrastructure.
"HARK" ACOUSTIC DRONE DETECTION SENSOR
Purpose-built for modern battlefield acoustics, the HARK sensor combines a high-precision microphone array with integrated edge processing to detect, classify, and localise drone and ground based threats in real time.
"LUPA" SENSOR MOBILITY
Arcani works with UGV manufacturers to provide a plug-and-play "living sensors" that enable the vehicle to understand where to optimally deploy the sensor, track alongside moving forces, manage C2 links, know when to return due to low battery, and track in GPS denied environments.
MANET INTEGRATION
We integrate with existing manet systems to ensure ease of use with existing nodes. Capable of transmitting very small packets of information, and therefore can be used on ultra-low bandwidth networks.
FORCE PROTECTION
Deploy distributed arrays of acoustic sensors for comprehensive area coverage and precise threat localization. Can be vehicle mounted or placed in high risk dead zones to plug gaps in detection capabilities (perfect for forested and urban environments with limited view of the horizon).
C2 INTEGRATION
Seamless integration with existing command and control systems for unified situational awareness. Experience integrating into ATAK (with a proprietary plugin, Lattice and other major C2 systems).

SWITCH ON,
DROP & GO
Designed to be deployed in a hurry, with as little complexity as possible. Portable sensor, vehicle or UGV mounted.
REQUEST A DEMOCONNECTED
the sensor is already connected to your existing mesh or MANET systems, passive until a detection is made.
LISTENING
the sensor will continuously listen for drone threats, trained on hundreds on drone airframes - even if it's not in our library, it will still identify the drone threat and give accurate elevation/cursor-on-target.
DETECTION
when a detection is made with sub-second latency C2 is notified with location of drone, Azimuth, height, drone group, drone model, speed, direction of travel among other meta data - updated 4 times per second.
LONG LIFE
Our sensors are designed to be able to run for days in harsh conditions, with hot-swap battery capability with no loss of power.
