64 Mic Acoustic Imager

High accuracy localization: Sound source localization and visual imaging, high accuracy positioning of gas leakage or discharge positions, and visual presentation through HD cameras. The positioning accuracy can reach within 1 °
Ultra wide frequency: It can locate sound sources in the frequency range from audible sound to ultrasound (5 KHz to 72 KHz)
24/7 real-time monitoring: Supports IP67 waterproof level and can be used in various outdoor and indoor scenarios
Free selection of the localization frequency range
