SPHEAR: acoustic drone & threat detection for security and defense

Overlapping acoustic detection zones of a SPHEAR sensor network around an industrial site

A passive acoustic dome around your site

SPHEAR is the security and defense brand of ASAsense. It deploys intelligent sensor networks that continuously listen to the acoustic environment and turn it into actionable intelligence, in real time.

Around any protected site, SPHEAR creates a passive acoustic perimeter dome that identifies every inbound or outbound acoustic signature, day or night, regardless of weather or lighting conditions.

More than drones

Drones are only the start. Ground vehicles, (under)water vessels and other incidents are identified by their unique vibro-acoustic signatures, then localised and tracked.

SPHEAR is built on ASAsense technology: the same smart sound capturing and AI models that power PAVEsense and AMBIsense.

From a single microphone to distributed arrays

  • Individual microphones: easy to deploy and low cost, for detection at 100 to 200 m.
  • Small arrays: localisation and better noise handling, at five to ten times the range.
  • Distributed arrays: a synchronised sensor network for very wide area coverage, precision localisation and tracking.

SPHEAR protects military sites and operations, airports and harbours, industrial sites and critical infrastructure, borders, detention centres, and government buildings.
