The world is going through a time of social distancing and quarantine. More and more, people are reluctant to come near each other. Also, the rise of multinational enterprises has resulted in a global scale distribution of human resources. All of these and many more reasons have given birth to a new necessity to keep in contact with people remotely and securely. Fortunately, video conferencing technology has been available for quite a few years now and the technology is now progressing in leaps and bounds. As in any piece of technology this also requires a variety of components. This article provides an overview of the various video conferencing equipment you need.
Video conferencing refers to the communication between two or more users in both audio and video channels. The components of this could be categorized into 4 major categories viz. input components, output components, processing system, and network components.
Input devices include webcams or even your mobile cameras. They capture and transfer the video information to the system for transmission. High definition cameras are the most desirable video input devices.
Input devices are usually mics that record and transmit the audio of the speaker to the system for transmission. HQ audio mics are available in the market for quite a small sum nowadays.
Output components display the video feed from the incoming video transmission. Some examples are monitors, projectors and screens. 4K or HD screens are the best possible options for excellent conference quality.
Output components include speakers or headphones which deliver the audio part of the incoming feed. Surround sound technology has been available for quite some time now and is almost indispensable in a good video conferencing setup.
CODEC aka Coder Decoder is the most important component of a video conferencing setup. It compresses and transmits the audio and video input files as packets of data. It is also responsible for decompressing and outputting this data at the receiving end.
A successful video conferencing system cannot exist without high-quality network connectivity. A good network connection should be fast as well as with minimal packet losses. Also, the network should be secure to prevent possible data leaks and to deter any hacking attempts.
Good video conferencing equipment integrates all these components seamlessly to provide an excellent atmosphere where distance does not matter at all.
