You control the conference via a desktop keypad that easily turns the system on
or off, dials the call, adjusts the audio volume, selects the video source, and posi-
tions the camera. The camera in most models has an auto-focus lens, plus zoom,
pan, and tilt capabilities that let users move the camera to follow conferees as
they move around the room. Optional capabilities include remote control of the
far-end camera and camera presets that let conferees set up to eight camera
positions — four local and four remote — each accessible at the touch of a button.
An automatic feature of most Group Video System models is the use of a window
(picture in a picture) for previewing, so you can see what your camera sees as
well as what the far-end camera sees. The window also permits simultaneous
viewing of far-end video and still-image graphics.
Group Video Systems are available in a variety of models that can accommodate
an office, small meeting room, or even a spacious board room. All models have
color monitors, with dual monitors available on most of them for simultaneous
viewing of video and high-resolution still images. The systems available are as fol-
lows:
■ PictureTel Venue
■ PictureTel 4000ZX
■ PictureTel Concorde 4500
■ PictureTel 4200ZX
■ Swiftsite 740/760/763
■ Polycom 4000
■ Polycom EX
■ Polycom Viewstation 1287/512/MP/V.35/DCP (H.320 and H.323 video over
IP)
■ Polycom Showstation IP (H.320 and H.323 video over IP).
Telephone add-on is an option on all models. This enables you to add a voice con-
feree to the video conference. Other options include security encryption,
freeze-frame graphics, and VCR recording — each providing additional benefits to
your video conference.
The monitors can accommodate both the U.S. National Television System Com-
mittee (NTSC) standard and PAL, the European 625-line standard, providing glo-
bal compatibility for your visual communication needs.
MultiPoint Conferencing Unit
When connecting more than two video endpoints, you can use the MultiPoint
Conferencing Unit to set up and conduct multipoint video conferences. This is a
stand-alone unit that provides easy-to-use multilocation video conferencing.
