SonicEye is an acoustic UAV detection system: a network of high-sensitivity probes and real-time signal analysis. Fully passive — it emits nothing and reveals no position.

Technology

Precision at the signal level

The outcome of acoustic detection depends on the entire chain: from the microphone membrane to the classification model. That is why we design every link as a coherent whole — mechanics, electronics, and processing.

CHAIN 01

High-sensitivity probes

Proprietary measurement electronics and a construction that limits mechanical and environmental interference.

CHAIN 02

Spectral and temporal analysis

Extraction of harmonic signatures from very low signal levels, in complex acoustic scenarios.

CHAIN 03

ML classification at the edge

Machine-learning models running locally (edge computing) — an alert is raised only after detection is confirmed.

Sensitivity and reliability

Detection often precedes visual identification

The system identifies unmanned objects at a stage where they are still invisible to an observer. The priority is not a single result, but repeatability over a long horizon.

Optimized for

  • very low signal levels
  • environmental interference
  • changing weather conditions
  • complex acoustic scenarios

Design priorities

  • long-horizon operational stability
  • measurement repeatability
  • environmental resilience
  • clear alerting and reporting
System variants

Two environments. One technology.

Civilian version · fixed installation

Permanent site protection

Permanent installation at the protected site. Continuous monitoring with no operator on location.

  • edge terminal + SIM router in an IP67 enclosure
  • one-time installation, autonomous operation
  • mobile app with push notifications
  • web panel for site security staff
Access and monitoring Security staff receive information on activity near the probe in real time — phone, push, web panel.
Specialist version · mobile

Field detection, zero RF emissions

For environments where radio emission is unacceptable. No network connectivity — no risk of revealing position.

  • ruggedized laptop in an armored case
  • wired connection up to 100 m
  • foldable sensor masts, probe on a tripod
  • processing and monitoring locally, offline
Operational scenario The probe outside a shelter, the operator with the laptop inside. Full awareness of the surroundings without exposing the team.

Probe construction

Form follows function

In acoustic detection, the result depends not only on algorithms but on the quality of the input signal. We designed the probe as a coherent whole: mechanics, electronics, processing.

Design assumptions

  • limiting the impact of mechanical and environmental interference on the measurement chain
  • minimizing signal degradation in field conditions
  • measurement repeatability in a changing acoustic environment

Effect in practice

  • more stable input data for the detection algorithms
  • fewer artifacts and spurious triggers
  • greater long-term predictability of operation

Pilot program

Don't take our word for it. Test it.

We enable partners to verify the system in real operating conditions. The goal is an objective assessment of effectiveness and adaptation of the system to a specific environment.

Applications

From a single probe to a distributed network

The system architecture scales from single installations to distributed sensor networks. Two variants cover both permanent site protection and mobile field operations.

Integration with existing infrastructure

SonicEye does not have to be yet another separate screen. Available APIs and integration tools allow acoustic detection to be embedded in the systems already running on site.

  • alarm systems and monitoring centers
  • security management platforms
  • SCADA and industrial systems
  • dedicated customer solutions
