Professional Acoustic Imaging Camera

About the product

The MPAC208 is a professional-grade acoustic imaging camera designed for fast, accurate detection of ultrasonic sound sources across industrial environments. It helps maintenance teams identify gas leaks, mechanical deterioration, and partial discharge (PD) in high-voltage electrical systems, without needing to interrupt operations. 
At its core is a 208 channel MEMS (micro-electromechanical system) microphone array offering sensitivity across 2 kHz to 100 kHz, enabling the MPAC208 to detect even very small leaks and subtle ultrasonic patterns. 
The acoustic data is fused with a 13 MP optical camera and displayed on an 8-inch capacitive touchscreen, presenting clear, real-time visual overlays that make sound sources immediately visible. 
The MPAC208-IECEx camera provides all the features seen in the standard MPAC208 but is certified for use in Class 2 explosive atmospheres.  
Designed for real industrial environments 
With a detection range up to 200 m, the MPAC208 is suitable for both close-proximity inspection and stand-off safety at substations, switchgear, or during overhead line work. 
The Focus function suppresses background noise, allowing operators to isolate target sound sources even in loud plants or workshops. SoundScan™ directional guidance assists in locating leaks that are outside the visible frame, helping technicians trace issues quickly  

Three core operating modes

• Gas Leak Mode: Automatically estimates leak rate, cost impact, and distance to the source, helping prioritise repairs and quantify energy loss.
• Partial Discharge Mode: Captures PD activity and provides PRPD (Phase Resolved Partial Discharge) analysis, supporting early detection and classification of discharge types.
• Mechanical Mode: Identifies bearing wear, valve leakage, cavitation, and vibration-related wear patterns through ultrasonic signatures.

Extend capability with thermal correlation

When fitted with an optional thermal imaging module, the MPAC208 enables side-by-side acoustic and thermal visualisation. This allows users to correlate heat signatures with acoustic anomalies for faster root cause assessment.

Built for field use

The camera is lightweight (1.4 kg), IP54 rated, and powered by interchangeable smart batteries providing up to 10 hours of operation (2× 5-hour packs included). 
Whether used in utilities, industrial plants, renewables, or manufacturing, the MPAC208 supports predictive maintenance, energy efficiency, and operational safety—all in one portable instrument. 

Camera Verification

The optional MPAC-V accessory is designed to allow field verification of the operational parameters of the MPAC cameras. An automated routine, built into the MPAC cameras, will verify the frequency response as well as the SPL (Sound Pressure Level) measured by the camera. In addition, it checks the visual location calibration of the microphones.
