What is Video Conferencing ?
A video conference is a live real time, visual communication session between two or more users residing in separate locations. This technology enables business meetings, routine meetings, business deals, and even interviews between different offices/branches located at far locations. Its use cases are endless as it saves a lot of time, cost and hassle associated with business travel.
Lately, many organizations have also implemented Video Conferencing to such an extent that it has become their preferred mode of communication over a direct telephonic call or audio conferencing.
Benefits of Video Conferencing
- Increase in productivity and efficiency of employees
- Lower travel costs (No need for physical presence)
- Reduce time to market by connecting stakeholders instantly for more productive discussions
- Engage more productively with the remote workers by seeing them more frequently
- Communicating face-to-face sends an indirect message before you say a word. By watching emotions, hand/body gestures and body language people tends to connect more deeply and it is also a very effective way to emphasize on key messages
- Opens a new era of smart classroom concept for the new generation and also provides education to remote areas.
- Host informative/educative sessions and provide employees training through materials visually and more quickly
Video Conferencing vs Video Collaboration
Nowadays, these two terms are often overlapped but when we talk about Video collaboration, it is one step ahead of Video Conferencing. While video conferencing is all about enabling video and audio communication between two or multi-parties, video collaboration is video call along with sharing of documents, presentation materials, whiteboards and similar group presentation visual aids.
Basic Components of Video Conferencing Infrastructure
- Display: Choosing the right display for your video conferencing system is the first step towards building an ultimate VC experience. It all depends upon your requirement, size of your conference room, usage frequency, surround lighting and your budget. Different variations are available for selection like Single Display vs Dual displays(one for video meeting and other for Data sharing), 4K option(Nowadays some VC systems also supports 4K resolution).

- Mic: Here also OEMs provide their own Mic with different specs like 360-degree coverage, 22 kHz of high-fidelity audio. There are two types of mic available:
- Table Top(Unidirectional)
- Ceiling Mic
- Processor (Codec): A processor/codec is a device or algorithm for encoding or decoding a signal with the help of pre-defined protocols. There are 3 main categories of protocols: Audio, Video and Data & Control. These codecs are necessary to encode and decode audio, video and data streams to network. For more info regarding protocols and codecs read here All about video conferencing protocols and video codecs
- Network: It includes all possible networks to send and receive video and audio streams from your system to remote one e.g. ISDN, Broadband, 3G/4G Network, Lease line, MPLS.
