Selection workflow

Four questions to narrow the choice

A suitable acoustic camera is selected by the inspection workflow, not by one specification alone.

Handheld or continuous?

Choose route-based field inspection, fixed 24/7 monitoring, PTZ coverage, robot mounting or OEM integration.

What must be detected?

Define the primary target: gas leakage, partial discharge, methane, mechanical noise or temperature anomaly.

Where will it operate?

Confirm distance, background noise, weather exposure, hazardous-area requirements and mounting limitations.

What output is required?

Consider images, video, reports, alarms, RTSP streaming, HTTP/WebSocket integration and platform workflows.
