20 MP | SONY 1-inch CMOS | Super-Wide 133° Field of View
20 MP camera with SONY 1-inch CMOS brings UHD 4K video conference with delicate
details. With super-wide 133° field of view, everyone in the conference can be seen
without adjusting the camera. Moreover, the image brightness can be automatically
optimized even in a dim or backlight environment, ensuring the participant faces can be
seen clearly.
Sound Localization for Full-Duplex Mode
8 MEMS microphone arrays make MeetingEye 400 have stronger ability of noise proof
and dereverberation. The new upgraded audio algorithm, together with the technology of
post-processing on acoustic echo cancellation and the dereverberation algorithm, brings
high quality full-duplex call and realizes more precise voice pickup.
Smart Video Conferencing with AI Technology
Featuring AI technology, including Auto Framing and Speaker Tracking, MeetingEye 400
can not only automatically adjust the image size according to the number and the
position of the participants, but also automatically zoom in the speaker without adjusting
the camera, making the participants more focus on the conference.
Secure Conference with Auto Camera Privacy Shutter
The camera privacy shutter automatically opens when the video conference starts and
remains closed when not having video conferences. The lens status is visible at a glance,
eliminating “lens anxiety” in daily conferences.
