Videoconferencing equipment
The term videoconferencing covers everything from a webcam to
a group videoconferencing system. A webcam, which sits on top of
a computer, enables two people to communicate with each other reasonably
effectively, although the quality can be variable. A group videoconferencing
system, which links to an interactive whiteboard, plasma screen
or television, enables larger groups of people to communicate using
higher quality audio and video.
Schools wanting to videoconference will need to acquire the necessary
equipment.
- A webcam will cost around £50. Used with a headset and
a piece of software like Polycom PVX, this will provide a surprisingly
good quality one to one link.
- With a USB mic/speaker costing about £50 this
system can support small group work. You could also use
your school’s camcorder instead of a webcam if you wanted
a better quality picture.
- Add a pan/tilt/zoom camera like
this one and link it to a whiteboard or plasma screen and
you have a pretty sophisticated system suitable for group and
whole class work.
- A basic, ‘standalone’ group videoconferencing
system like this one will
cost between £2000 - £2500.
- There are also ‘refurbished’ group systems on
the market which are well worth considering at around the £1000
mark. The DMEC is currently offering a ‘package’ which
includes a Polycom Viewstation EX,
with installation and training for £1300.

Group videoconferencing systems are produced by a range of manufacturers
including:
Videoconferencing systems are not sold directly by the manufacturers,
but by authorised resellers. A search on Google will come up with
dozens. The key is always decide which system you want and then
to get at least three quotations for it. As well as the price make
sure you find out how long the manufacturers warranty is and what
after-sales service the reseller is offering free of charge. Some
resellers also offer packages of support for sale which you need
to look at very carefully before purchasing.
If you would like some advice on which systems are the best for
classroom work and where to go for quotations, you’re welcome
to contact the dMEC.
