COTT-CK07 Hemisphere Passive Pickup

main features
The COTT-CK07 hemispherical passive microphone is specially designed for network cameras and network video servers such as Hikvision, Dahua, and Yushi.
Adopting a honeycomb shape can eliminate reflective phase distortion, suppress echo, and provide clear and high-quality audio signal output.
Using KaBoni professional recording interview omnidirectional microphone, with high fidelity, high sensitivity, high bandwidth, and no noise within 50 square meters.
The device adopts two core signal transmission, with output mode of 3.5mm MIC JACK and transmission distance not exceeding 10 meters.
Adopting the principle of "Temple of Heaven Echo Wall", the 0.8mm pinhole design achieves the best accurate calculation of sound reflection angle.
The digital noise reduction signal processing circuit improves the signal-to-noise ratio and reduces distortion caused by phase shift, greatly improving sound quality.
