HIKMICRO AI56 Acoustic Imaging Camera

Key Features:

64 Low-Noise MEMS Microphones — High-density array enables precise, real-time sound source localization even in noisy industrial environments.

Wide Frequency Bandwidth (2 kHz – 65 kHz / up to 96 kHz adjustable) — Detects both audible and ultrasonic sound, suitable for gas leak detection and partial discharge monitoring.

Long Detection Distance (≈ 0.3 m to 100–150 m) — Enables safe inspection of large or hazard-prone assets like high-voltage systems or pressurized gas lines.

Leak Sensitivity — Detects very small gas leaks (e.g. > 0.008 L/min at 6 bar from 0.5 m; > 0.013 L/min at 5 bar from 1 m) for early detection and mitigation. 

Partial Discharge Detection Modes — Automatically identifies corona, floating, surface, and particle discharges in high-voltage equipment (50/60 Hz) for preventive maintenance. 

Large 4.3-inch LCD Touchscreen (800×480 resolution) — Overlay acoustic image onto visual image, with rich color palettes for better visualization.

Multiple Acoustic Palettes & Adjustable Digital Zoom — Use 8 different palettes (White/Black, Rainbow, Fusion, Ironbow, etc.), plus continuous zoom (1.0×–8.0× or up to 16× depending on firmware) to adapt to different inspection scenarios.
