HA3 handheld acoustic camera for field inspection.

HA3 is a handheld acoustic imaging camera designed for industrial inspection. It uses a 144-channel MEMS microphone array and AI beamforming algorithms to visualize ultrasonic sound sources and help engineers locate gas leaks, partial discharge and abnormal mechanical noise. It is suitable for power, oil and gas, manufacturing, data center and heavy industry inspection workflows.

144

Digital MEMS microphones for high-density acoustic imaging.

2kHz–150kHz

Wide frequency bandwidth for audible and ultrasonic inspection.

0.3–210m

Operating distance for close-range and long-distance inspection.

Product Family

Acoustic Imaging Cameras

Compare HA3 with HA3T, HA3LX and fixed online acoustic cameras for different inspection workflows.

From ultrasonic sound to visual inspection evidence.

HA3 series acoustic camera combines a high-density MEMS microphone array, beamforming algorithms and optical image overlay. The camera captures sound arrival differences, calculates the sound source direction and displays the result as an acoustic heatmap over the visual image.
HOW IT WORKS

01

Sound Capture
144 digital MEMS microphones capture audible and ultrasonic sound signals from the target area.

02

Beamforming
AI beamforming algorithms suppress background noise and focus on target sound sources.

03

Visual Overlay
Acoustic heatmaps are displayed over HD optical images for intuitive source localization.

04

Inspection Output
Engineers can capture images, videos, annotations and inspection records for maintenance reporting.
