Squarehead Technology

What Squarehead Technology does

Squarehead Technology is a Norwegian defense and industrial technology company founded in 2004 that builds passive acoustic beamforming microphone array systems for threat detection and condition monitoring. Its core technology combines proprietary directional array hardware (128-microphone arrays with integrated optical cameras) with digital beamforming algorithms and machine learning to localize, classify, and track sound sources — including drones, RAM events, and industrial machinery anomalies. The company sells two main product lines: the Discovair G2+ passive sensor and Discovair C2 command-and-control software for defense and security (drone detection, Counter-UAS, Counter-RAM), and the HX128 industrial microphone array with OPC-UA feature streaming for industrial and maritime condition monitoring (engine rooms, pump rooms, process facilities, nuclear, LNG).

The company generates revenue through hardware sales (sensor arrays), software licenses and subscriptions (Discovair C2, array server), defense procurement contracts (Norwegian Armed Forces P5007, NDMA C-UAS framework via OSL), and managed services for maritime autonomous vessel operators (Fjord1, Reach Subsea). It goes to market via direct enterprise sales, its own subsidiaries (including Squarehead Technology LLC in Hickory, NC), distributor channels, and system integrator partnerships, with active presence at major defense shows (Farnborough, Eurosatory, MSPO, DSEI, AUSA) and maritime industry events. Customer segments span defense and military, industrial and manufacturing (pulp & paper, metal), maritime and offshore (including autonomous and remote-operated vessels), nuclear power, and energy/process industry, with employees distributed across four countries.

Core offering

Squarehead Technology designs, manufactures, and sells passive acoustic microphone array systems that combine proprietary digital beamforming algorithms with machine learning to detect, localize, and classify sound sources. The company operates two product lines: the Discovair system for defense and security (passive drone detection and acoustic Counter-RAM for rocket, artillery, and mortar events) and the Industrial Microphone Array (HX128) for industrial condition monitoring, predictive maintenance, and acoustic anomaly detection in maritime, manufacturing, and process industries.

Product overview

Squarehead Technology offers two main product lines: the Discovair system for defense and security applications, and the Industrial Microphone Array for industrial monitoring. The Discovair system consists of the Discovair G2+ passive acoustic sensor (128 microphones with integrated optical camera) and Discovair C2 command and control software. The Industrial line features the Squarehead Microphone Array with over 100 acoustic sensors plus optical camera. Both product lines leverage patented beamforming technology and machine learning for sound source localization, classification, and anomaly detection. The defense system provides drone detection and Counter-RAM capabilities while the industrial system enables condition monitoring, quality control, and acoustic asset management across maritime, manufacturing, and process industry applications.
