There is a wide variety of peripheral equipment, such as
cameras, document cameras and microphones, which can enhance
videoconferencing systems and support many different
applications. Some examples are described below.
- Auto-tracking Cameras can follow the
speaker and are particularly useful in classroom
environments.
- Document Cameras are used to show live
images of hard copy documents and 3D images to the remote
end.
- Scan Converters take a VGA computer
display and convert it to NTSC (video) format for display on
a video monitor. Participants can have collaborative work
sessions through document sharing and PC applications.
- Video Printers print the television
monitor screen image.
- Videoconference Lighting makes a
dramatic difference in how you look to people on the other
end of conferences. These are special color temperature
lights that attach to your ceiling or can be tripod mounted.
The correct lighting illuminates your face, providing the
camera with a more accurate color rendition of your skin
tone. You will appear more 3-dimensional, rather than flat.
(Normal fluorescent office lighting can make you appear
green in a videoconference.)
- Videoconference Furniture will be
necessary if you are planning to convert your existing
conference room into a videoconference room. It might be
time to replace the old table and chairs with new, more
videoconference-friendly furniture. Proper videoconference
tables are wedge-shaped so that the maximum number of people
can be seen on camera. In addition, you will want to place
your conferencing equipment on appropriate carts and stands.
- Video Processors are needed to
manipulate video signals from multiple sources. A typical
unit allows for multiple image displays on a single screen.
It can also alter the video levels and contrast to correct
for differences in video signals from different sources.
