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.

<1kg

Lightweight handheld design for field maintenance teams.

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.

Specifications

What type of lines is HZ-TWF-30 designed for?

HZ-TWF-30 is designed for medium-voltage overhead distribution lines. It is suitable for overhead distribution network monitoring, fault localization and remote line diagnostics.

How does traveling-wave fault localization work?

When a fault occurs, high-frequency traveling-wave current signals are generated. The system captures these transient signals and uses synchronized timing analysis and traveling-wave algorithms to calculate the fault position.

Can HZ-TWF-30 be installed without power interruption?

Yes. The system supports live-line installation, making it suitable for distribution line deployment without interrupting normal operation.

What fault types can the system detect?

The system supports ground fault, short circuit and open conductor fault detection, and can also support abnormal discharge, hidden hazard monitoring and lightning vs non-lightning event discrimination.

How does the system communicate with the platform?

Field devices transmit data through 4G / APN private network communication to the HERTZINNO cloud-based monitoring platform.
