Where acoustic cameras are used

Handheld acoustic cameras are suitable for mobile inspection teams that need quick, visual and repeatable diagnosis.

Substation Inspection

Locate partial discharge, corona and abnormal ultrasonic emissions from electrical assets.

Oil & Gas Facilities

Find pressurized gas leaks, methane-related leak sources and pipeline valve leakage points.

Factory Utilities

Detect compressed air leakage, vacuum leakage and abnormal sound sources in production facilities.

Monitoring Architecture

From acoustic sensing to remote alarm workflow

Online acoustic cameras combine microphone arrays, optical imaging, acoustic source localization, edge analysis and communication interfaces to build a continuous monitoring workflow.

One system for sound source localization, visual verification and platform integration.

The camera captures audible and ultrasonic signals, overlays the acoustic source on the visual image, analyzes abnormal events and sends video, alarm or diagnostic data to the monitoring platform.

Sensor Layer MEMS microphone array, optical image and optional thermal imaging.

Analysis Layer Beamforming, sound source localization, leak localization and PD-related acoustic analysis.

Alarm Layer Event alarm, acoustic image, visual evidence and historical trend support.

Integration Layer Ethernet, HTTP, WebSocket, RTSP, robot system or third-party monitoring platform.

Key Applications & Demos

Partial Discharge Detection

Precisely locate PD sources (±15cm) from 200m away. Automatically classifies discharge types (Corona, Surface, Internal) and assesses severity using PRPD mapping to prevent failures.

Gas Leak & Cost Analysis

Detects leaks in Compressed Air, Hydrogen, SF6, and Natural Gas (20-100 kHz). Built-in AI estimates leakage volume and calculates annual energy loss costs in real-time.

Mechanical Fault Diagnosis

Visualize sound maps to identify bearing damage, blade imbalance, and misalignment in motors and fans. Pinpoints the exact location of faults to shorten troubleshooting time.
