Video conferencing 

Video conferencing
- a type of online meeting where two or more people engage in a live audio-visual call.
With a strong internet connection, the participants can see, hear, and talk to each other in real time, no matter where in the world they are.

In business, people typically use video conferencing to communicate and collaborate within and outside an organization.
You just need to set up the necessary hardware and software to get the most out of the experience.

What are the basic components of a video conferencing system?

Video conferencing brings people working from different places together in a virtual meeting room. To make that possible, you’ll need:
A stable internet connection
A video display device (laptop, desktop monitor, or a television screen)
A computer or conference phone
Other peripherals (webcam, microphone, headset, speaker, etc.)
Video conferencing software

Some offices have dedicated video conference rooms where they keep high-definition cameras and video displays as well as top-quality audio systems designed specifically for meetings.
This amplifies the experience, of course—but the truth is, you can have effective video meetings with just a laptop and the right software.

Types of video conferencing

Multipoint conferencing
Point-to-point conferencing

Point-to-point conferencing
In point-to-point video conferencing, there are only two participants communicating from different locations in real time.

One-on-one customer support
Most modern businesses are equipped to provide personalized customer experiences. With the right equipment and software, they can address concerns and inquiries in an instant.

Job Interviews
Employers can speed up the hiring process by conducting job interviews online. This has become a pretty common practice especially for companies that offer remote flexibility.

Multipoint conferencing

Multipoint video conferencing involves three or more participants; that’s why it’s also called “group video conferencing”. This is different from the three-way calling that comes as a feature with many business phone systems.
With multipoint conferencing, you can host or join meetings with larger groups. This makes it ideal for businesses with several office locations and remote workers. In cases like this, a conference bridge comes in handy.

Multipoint conferencing

A conference bridge is basically software or hardware used as a hub for a large conference call. Think of it as a way for different groups of people to join a single meeting.
There are many ways for you to conduct a multipoint video conference, typically depending on the number of active speakers in the meeting and the total number of participants.

Multipoint conferencing

Team meetings

Workers conduct team meetings to achieve a specific objective.
It calls for higher-quality cameras to capture a room full of people and an expansion microphone to make sure your audio is clear.

Multipoint conferencing

Webinars

A webinar is an online presentation that aims to educate participants.
Unlike team meetings, which are open discussions, webinars put the focus on the speaker or facilitator.
Businesses typically use this format for product launches and demos.

How does video conferencing work?

Video conferencing is powered by VoIP, the technology that makes voice communications over the internet possible.
In order to transfer audio and video signals between two locations, VoIP relies on special algorithms called codecs (coder-decoder).

Data compression (coding)

Imagine an ongoing video meeting. The camera captures analog video signals and, when someone speaks, the microphone captures their audio signals.
VoIP turns these signals into data packets for the internet to understand and for the transfer to begin.

Data transfer and decompression (decoding)

The packets of data travel over the internet. When they reach their destination, they change back into analog video and audio signals for the attendees on the other side to see and hear.

Conferencing solutions typically come with echo cancellation to eliminate sound delays.
This way, the audio and video remain in sync.
Depending on the provider you choose, you’ll find that there are numerous other features that make video conferencing such a powerful business tool.

Key features of video conferencing software

Screen sharing
Device switching

Video conferencing benefits

Improved productivity
Humanized conversations
Superior communication
Time and cost savings
Well-structured meetings
Remote workforce support

Improved productivity
Video conferencing software typically comes with screen sharing, file transfer, group chat, and other features that enhance collaboration.
None of that is possible with other forms of communication like audio conferencing, SMS, or email.
When everyone is in sync, they make informed decisions faster and work more efficiently.

Humanized conversations
The visual component humanizes the conversation, making video conferencing much more engaging than other forms of communication.
It allows you to see body language and facial expressions even without engaging in face-to-face interactions.

Superior communication
Humans process visual data faster than they do text or audio.
Compared to an audio meeting, it’s more likely for meeting attendees to understand and retain information more effectively when video is involved.
Visuals can also help keep them alert and focused on the discussion.

Well-structured meetings
The start and end time of video conferences are usually predefined.
This way, attendees have less time for idle talk and are more likely to stick to the agenda.

Time and cost savings
In most cases, the goals of an in-person meeting can also be accomplished through video conferencing.
Job interviews, webinars, and business meetings—all these can be done without having to spend gas money and endure insane traffic just to get to a specific place at a specific time.

Remote workforce support
The rise of video conferencing made the possibility of having a completely remote workforce even more valid.
Proof of this is the fact that businesses can now operate without a physical office and hire staff from all over the world.
