FOTRIC H4Mini Acoustic Imaging Camera
- Advanced Mini Acoustic Imaging Technology
FOTRIC H4Mini Acoustic Imaging Camera is a compact, professional inspection tool equipped with 112 high-sensitivity MEMS digital microphones and a 66°×52° acoustic field of view. It covers a wide frequency range of 2kHz–100kHz to detect ultrasonic signals beyond human hearing, paired with a 13MP industrial-grade digital camera for clear visual reference, enabling accurate and fast sound source localization.
- Fast & Non-Contact Leak & Fault Detection
This lightweight acoustic camera quickly identifies compressed air leaks, vacuum system leaks, equipment loose joint vibration, and tire air leaks without shutdown or contact. It visualizes abnormal sound sources in real time, helping maintenance teams locate hidden faults in seconds, reduce downtime, and avoid costly equipment failures.
- Multi-Mode Imaging & Professional Diagnostic Tools
Supports single-source, multi-source, and hologram imaging modes for flexible adaptation to on-site noise conditions. It features exclusive T-FFTD® acoustic image delay to capture instantaneous sound signals, acoustic image focus for targeted localization, and precise SPL measurement for industrial-grade sound signal diagnosis.
- On-Board Intelligence & Easy Data Management
The H4Mini supports on-device acoustic report generation to export inspection data directly. It includes QR code/barcode scanning for quick annotation, gray-scale background display, and a favorites function for efficient image sorting and management, streamlining on-site inspection workflows.
- Ultra-Compact & Rugged Portable Design
Weighing only 770g for one-handed operation, this camera features a 3.5-inch IPS LCD touchscreen (640×480) and an IP54 rugged rating. Equipped with a 5000mAh field-replaceable lithium battery for ≥4 hours of continuous use, it is ideal for long-duration field inspections in industrial, HVAC, manufacturing, and utility scenarios.
