Description
FOTRIC H4mini Acoustic Imaging Camera
The FOTRIC H4mini is a lightweight device weighing only 770 g, designed for industrial performance. It empowers maintenance teams to locate leaks with clarity and speed—without the need for shutdowns or guesswork.
At its core is a 112-MEMS digital microphone array, which offers nearly double the density of typical compact imagers. This advanced acoustic engine provides sharper imaging, higher sensitivity, and faster localization during real-world inspections.
The H4mini does more than just find leaks; it also helps quantify their impact. Its Leak Evaluation Mode estimates the severity of leaks. This allows maintenance teams to prioritize repairs and reduce wasted energy using real data rather than assumptions.
Acoustic Image Delay (T-FFTD®)

The FOTRIC H4mini utilises a multi-modal transient acoustic matrix to enhance microsecond-level acoustic event retention.
You can boost signal retention and enhance inspection efficiency for intermittent sound sources.
Acoustic Image Focus

This combines adaptive dynamic noise reduction algorithms to achieve focused localisation of sound sources.
Source Mode Switching

The H4Mini Acoustic Imaging Camera supports multiple image modes, including single-source, multi-source, and holographic views, allowing users to adapt to varying noise complexities and detection targets on-site.
Flexible Capture Modes

The H4Mini camera supports holographic image capture, holographic video recording, and time-lapse capture, enabling inspectors to make comprehensive documentation on-site.
Precise SPL Measurement

Combining holographic imaging and decibel data measurement, the FOTRIC H4mini camera is capable of industrial-level sound source tracking and signal diagnosis, enhancing acoustic inspection efficiency and user safety.
