Fixed acoustic and thermal imaging for continuous monitoring.

HZ-FA-371T captures acoustic signals through a 128-channel MEMS microphone array and temperature information through a 640×512 infrared thermal module. Acoustic imaging algorithms locate sound sources, while infrared imaging identifies temperature anomalies. Fusion imaging helps operators correlate sound-based faults with thermal patterns for more reliable online diagnostics.
