video communications
systems that allow two-way or multi-way calling with live video, essentially just a telephone system with an additional visual component. Primarily because of cost (but also compatibility problems), early use of video systems was primarily in advance-scheduled videoconference meeting rooms.
Video is advantageous when visual information is being discussed, but may not provide substantial benefit in most cases where conventional audio telephones are adequate. In addition to supporting conversations, video may also be used in less direct collaborative situations, such as by providing awareness of activities at a distant location.
