About SPHEAR

Security and defense brand SPHEAR operates through sound, deploying intelligent sensor networks that continuously monitor the acoustic environment and extract actionable intelligence in real time.

As a pioneer in vibro-acoustic detection technology, SPHEAR specializes in advanced sound recognition models for security, defense, transport, and industrial applications. The technology continuously "listens" to the environment, enabling real-time detection, classification, and interpretation of events based on acoustic data.

SPHEAR creates an passive acoustic perimeter dome around any protected site — identifying every inbound or outbound acoustic signature, day or night, regardless of weather or lighting conditions.

In addition to drone detection, inbound and outbound movements of ground vehicles, (under)water vessels,... as well as other incidents can be identified by their unique vibro-acoustic signatures.
