A video conference allows two or more locations to communicate via live, simultaneous two-way video and audio transmissions. A video conference system is generally costlier than a videophone and deploys greater capabilities.

 This is often accomplished by the use of a multipoint control unit (a centralized distribution and call management system) or by a similar non-centralized multipoint capability embedded in each videoconferencing unit. 

Technology improvements have circumvented traditional definitions by allowing multiple party videoconferencing via web-based applications.
