Description

The DH-HAP201 from Dahua is a functional audio component whose task is to detect background noise, well suited for CCTV systems. It is equipped with a microphone embedded in an attractive, plastic housing, thanks to which it will work in any space. Particularly suitable for installation in suspended ceilings, as the part of the component protruding from the ceiling contour is small and goes unnoticed without disturbing the appearance.

We present HAP201 - an excellent audio sampling module for all your audio needs. Thanks to the built -in processor, this audio sampling module offers unparalleled performance and low hardware interference. In addition, it boasts intelligent protection against audio cracks and automatically lowering the microphone sensitivity to ensure a sharp, clean sound. HAP201 also uses the technology of processing a wide range of dynamics for the correct sound, and its high sensitivity microphone ensures highly reception for pure high resolution sound. In addition, this module also has a noise reduction function with a powerful algorithm, as well as automatic strengthening and compensation for the frequency of human voice. In addition, HAP201 contains a scream control function to strengthen the vocal tones, and its built -in fast processor offers real -time sound processing. Thanks to all these functions and more, HAP201 is the perfect choice for all your audio needs.
