The DS-QAAI264G1-P 64 Mic Acoustic Imager is a high-performance device that combines an advanced microphone array and a camera component to achieve sound source localization and visualization. It visually maps acoustic patterns, making it highly effective for identifying leakages and electrical faults.
Features sound source localization and visual imaging with a positioning accuracy of within 1Ā°. It accurately identifies gas leakage or discharge points and presents them visually through an HD camera.
Supports a wide frequency response range of 2 kHz to 72 kHz, and a localization range of 5 kHz to 72 kHz. This allows localization of sounds from audible range up to ultrasound, effectively filtering out background noise.
Designed with an IP67 waterproof rating, enabling stable deployment in both indoor and outdoor environments for continuous equipment health monitoring.
Supports decibel threshold detection, frequency threshold detection, sound source localization anomalies, microphone exception, and video tampering. Triggers can upload reports to a memory card, notify the surveillance center, or initiate recording and image capture.
Ideal for partial discharge detection and diagnostic troubleshooting of electrical equipment.
Designed for gas leak detection and isolating abnormal equipment noise locations.
Applicable in server rooms and storage hubs to monitor hardware operation status.
