There are several key components required to succeed or participate in a video conference. This:

1) Video In – Video conferencing by definition requires video in. This is usually done using a webcam or, less often, a camcorder.

2) Audio In – To accompany the audio-video, there must also be an audio input. This is mostly done using a microphone, although DVD / CD players are also a source of audio

3) Video Output – For a video to be interpreted, there must be a platform for video output. This can be done through many elements, but most often through a computer monitor, television, or projector

4) Audio output – similar to video output, but for sound. Audio is usually output through speakers.

5) Data transmission – video/audio data is usually sent over telephone networks (analog or digital), Internet, or LAN (local conference time).

6) Computer – A computer is required to connect other components of the conference. Computers also compress and decompress data using codecs and maintain connections between data over the network.

On the whole, these are the components that make up a video conferencing system. There are two types of systems; dedicated and desktop. A custom system is a device in which all the necessary components are custom made and manufactured.
