The Logitech® BCC950 ConferenceCam combines HD 1080p 30 fps video with high-quality full-duplex speakerphone clarity for professional video conferencing. This cam features the UVC H.264 onboard technology which helps to ensure plug-and-play functionality on both PCs and Macs, with no software to install. Also, you can easily control your meetings with the remote - answer/end calls, set volume up/down, pan, tilt, zoom and mute. Plus, the built-in, full duplex speakerphone and noise-cancelling microphone allow all meeting members to hear and be heard clearly up to 8-feet away from the base. Additionally, its camera height extender and 8-foot USB cable allows you to adjust camera height and distance for the flattering video angles so they can make the fine impression during meetings. Furthermore, a 78-degree field of view and 180-degree remote-controlled video pan, tilt, zoom ensures each member of the small group is seen. Enjoy razor-sharp images from a glass lens designed with the help of Carl Zeiss® allowing detailed documents, whiteboards, or visuals to be shared close up during calls. Moreover, the omni-directional sound and echo cancellation audio makes it seems like conversations are happening in the same room. With all these features and more, this ConferenceCam is an ideal way for professionals to meet face-to-face, without leaving the desk.
