The four common types of videoconferencing systems in use today are Telepresence conferencing systems, Integrated video conference rooms, Set-Top video conferencing systems and Desktop conferencing systems.
Telepresence
systems give the appearance of being present
(tele-present) in an actual meeting even though the
participants are geographically dispersed. Telepresence
systems can either be portable (roll-about) or Immersion
(room based). This type of group meeting system usually
consists of a high definition codec coupled with several
very large flat panel display devices and integrated hi
fidelity audio. Telepresence systems generally range
from $60,000 to $300,000 each, depending on the size and
capabilities of the equipment.
Integrated room
conferencing systems are group conferencing systems most
often used in conference rooms, board rooms, or
classrooms with multiple participants. This type of
system usually consists of a centralized location for
the codec and associated hardware. The main camera,
displays and peripheral video sources are usually
permanently mounted in the main conferencing area. These
customized configurations are normally equipped with
multiple features and also allow for the
videoconferencing room to be used for various other
functions as well. Room integrated visual communication
systems generally range from $10,000 to $100,000 each,
depending on the size and capabilities of the
equipment.
Set-tops are complete videoconferencing systems designed to sit on a monitor. They are useful in small conference rooms and other small group venues. Set-top video communication systems are often maintained on a cart, making it possible to roll them around for use in different rooms (roll-about). Set-top systems are typically priced between $3,000 and $20,000 each depending on the capabilities of the equipment.

Desktop
videoconferencing systems bring video communications
into your personal workspace. This technology can
deliver full-motion videoconferencing from your PC.
Desktop systems have been engineered to accommodate the
industry's requirements for standards-based
videoconferencing. Today, there are systems available
that deliver good quality at a low cost. These systems
provide H.323 voice and video, as well as applications
sharing. Desktop systems are typically composed of a
software package and USB or FireWire camera. Desktop
systems normally are priced between $250 and $400.
