KCA20H
Name:KCA20H HD conference camera (20x optical zoom) Type:KCA20H

  • Features:

  •  A new generation of ISP image processing algorithm provides more complete white balance and automatic exposure functions, which significantly improves the camera image output performance and makes the imaging effect better. It is widely used in educational recording and broadcasting, distance education, video conferencing, live broadcast, and broadcasting. and other industries

  • 1080P60 NDI®|HX (optional), which can achieve high-resolution video through lower network bandwidth transmission

  •  Full-interface low-latency technology, all video output interfaces meet low-latency indicators, support 4 ports at the same time and all support 1080P60

  •  Adopt advanced focusing algorithm to enable the lens to focus quickly, accurately and stably

  •  Exclusive audio processing algorithm

  •  It can eliminate reverberation, effectively reduce environmental noise, and supports EQ adjustment to optimize sound effects. The device supports dual mic sound pickup, and can also be connected to an external microphone, wireless bee, etc., to meet the sound pickup needs of most scenarios.

  •  Rich video interfaces

  •  Support SDI, HDMI, USB 3.0 and network audio and video output
