What You'll Need (Detailed)
Exactly what you'll need to
start videoconferencing:
A Functioning Computer with an Internet Connection
The title of this requirement is slightly
misleading: you need a good working computer, not just one that functions.
Depending on your goals, you may need a more or less powerful computer.
This guide recommends at least a Pentium III computer running Windows2000
or WindowsXP. However, most of the implementations in this guide
will probably run competently on a Pentium II computer running Windows95
or above.
For the internet connection, there are many satisfactory
options. Any user with a high speed internet connection (T1, T3
or DSL lines) should have no problems at all. Users with medium speed
connections (ISDN lines, Cable modems) should be alright, but might not
get the highest quality conferences. Dialup modems, while they are
capable of transmitting and recieving audio and video, will severely
limit the quality of the conference. For a more detailed discussion
of connection options, click here.
Speakers and a Microphone
In order to hear the videoconference, you
must have properly configured speakers of some type. In order to
speak to the conference, you must have a properly configured microphone.
A headset with microphone is recommended, since it effectively isolates
the speakers and microphone in order to minimize feedback. Speakers and microphones
can be easily purchased from any computer store for a low price (a good
headset can be obtained for under $20). Don't know where
to get one? Try www.jandr.com

A Digital Videocamera
The videocamera is what makes for a videoconference
rather than just an IP phone call. In order for you to be seen
by the other conference participant(s), you must have a functioning videocamera.
Computer videocameras run the gamut from cheap and bad to expensive
and great. Luckily, there is a very good middle ground. Many
companies sell perfectly suited USB
videocameras in the $40 to $100 range. To set the camera up
for videoconferencing, just follow the manufacturer's instructions. Don't

or www.amazon.com.
Client Software
The requirement of client software is where
most of the variance in videoconferencing setups arises. There are
many clients available; some for free, some for very high prices. While
some are compatible only with themselves, many use the same standard.
Your choice of client is entirely dependent upon your needs and
budget. For a detailed discussion of different clients, click here. Keep in mind that the majority of
stand-alone units use the H.323 protocol, so if you'd like to be able to communicate
with one, you'll need an H.323 compatible client.
Time
Like most projects, IP videoconferencing takes
time to set up. With no problems (while highly unlikely, it does
happen sometimes...) the process can take only an hour or two. However,
since things rarely run as smoothly as they should, plan on spending at
least a day getting everything running.
