This document describes an Intelligent 4K All-in-one Video Bar, a comprehensive solution for video conferencing. It integrates a 4K UHD camera, microphone array, high-fidelity speaker, and an electric privacy cover into a single device. The video bar is designed to enhance communication with advanced features like face recognition, voice localization, voice tracking, and intelligent noise reduction.
Function Description:
The primary function of this device is to provide a high-quality, all-in-one video conferencing experience. It automatically adjusts image size based on the number of participants to ensure optimal framing. It can detect and track the speaker in real-time, providing close-ups for a hands-free operation. The integrated 6-array MEMS microphone system, coupled with advanced 3A audio algorithms, delivers exceptional full-duplex communication. The device also functions as a Bluetooth speaker and microphone, allowing connection to mobile phones and other Bluetooth-enabled devices.
