Video conferencing refers to all online video communication tools that aim to replicate the experience of face-to-face meetings while removing the need to travel.
Originally developed to work only between two sites, modern systems can bring together a number of people at different locations.
Systems vary between small scale desktop technologies using simple web cams to state of the art so-called telepresence suites that use large high resolution screens in special meeting rooms to closely replicate the experience of face-to-face meetings.
Low resolution screens and slow internet connections initially hampered adoption of video conferencing systems, but demand for the technology has soared in recent years as more and more businesses have signed up to an approach that promises to both cut carbon emissions and travel costs while boosting staff productivity.
