Video Conferencing

Meetings often require long, expensive and tiring travel. With a network, cheap cameras and microphones, and perhaps email or fax, distant branches of an organisation can communicate 'face-to-face' with videoconferencing. It is immediate, cheap and convenient.

It allows immediate communication between neighbouring offices or distant countries. Law courts use videoconferencing to hear from witnesses who could never have attended personally because of time, distance, cost or health constraints.

Not having to travel is a boon for businesses. Workers do not have to stop work to travel to meetings, so business can proceed and workers do not have to return to find piles of work waiting on their desks.

With software such as Netmeeting, workers can:

  • Share ideas, information, and applications using video or audio.
  • Send and receive real-time video images using Windows-compatible equipment.
  • Send video and audio to a user who doesn't have video hardware.
  • Use a video camera to instantly view items, such as hardware devices, that are displayed in front of the lens.
  • Remotely make the trade-off between faster video performance and better image quality.
  • Add on services such as an electronic whiteboard which lets teams collaborate in real time with others via graphic information.

Some interaction will always still need personal face-to-face contact and a handshake, but for many other occasions video conferencing can be just as effective.
