Video Conference System

A video conference system is a telephone based system that allows participants in a telephone conference to communicate with each other through the use of two way communication devices. These systems allow people in various locations to connect to each other in real-time using telephone lines and computer networks. Videoconference technology is being used for more business and professional activities. A conference system provides a highly effective method for large groups of people to interact in a face-to-face manner, while reducing costs, and improving the quality of the interactions.
