Digital video camera auto-track Conference System

With the videoconference is more and more popularization, the requesting of the
meeting equipments are higher for the multi-functional meeting room, it need the
function of video camera auto-track in lots of the discussion meeting situation. Our
company developed the multi-functional meeting control system on the base of
summarizing the experience of videoconference and speaking system for many years.
The system control software have soft keyboard function may replace various kinds
of video-controlled keyboard, it’s more convenient to operating.

Please see the figures of Video Camera Auto-track System, before the meeting
begins, set each microphone corresponding the video recording position of the
camera. When some delegate press the speaking button to make a speech, the annular
red indicator lamp glimmers on the microphone, and the camera aims at the
spokesman automatically according to the position settled in advance. After the
delegate’s speaking, the system is turn to tracing other spokesman’s position
automatically.
