What Is Video Conferencing and How Does It Work?
Video conferencing has become the norm in many sectors worldwide, especially in hybrid and remote work environments. It became essential during the COVID-19 pandemic – as teams were unable to meet in person or work in offices as usual – but has remained a common practice post-pandemic.
It’s easy to see why, as video conferencing offers convenience, flexibility and cost-saving compared to face-to-face meetings, while also fostering team dynamics and collaboration more than audio-only calls. The tools for video conferencing have also improved considerably over the last few years, in response to greater demand.
But what exactly is video conferencing and how does it work? Find out everything you need to know below, including the business benefits and which industries it’s commonly used in.
What Is Video Conferencing?
A video conference is a live, real-time audio-visual communication session between two or more people. It’s an online meeting, conducted over the internet using devices such as computers, laptops, tablets and phones. These make use of cameras and microphones so that everyone can see and hear each other.
Video conferencing platforms facilitate one-to-one and group meetings, as well as webinar-style broadcasting and conference room systems.
How Does Video Conferencing Work?
Video conferencing works by capturing audio and video, and transmitting it over the internet to other participants in real-time.
Hardware such as your laptop camera and microphone capture the data (video and audio), then the video conferencing platform software compresses it and sends it across the internet. The software installed on the receiving participant’s device decodes the data and displays it in real-time.
All of this happens in fractions of a second (provided there is a strong and reliable internet connection on both ends), so it’s just like having a real world, face-to-face meeting or conversation.
So how do you join a video conference? To set up or attend a virtual meeting, you need three key things:
- A device with access to the internet – such as a laptop, tablet or smartphone
- An account with a video conferencing platform such as Microsoft Teams, Zoom or Google Meet
- A way to invite participants – a common option is an email or message containing a link to the meeting, or a calendar invite.
There are also a number of key network requirements, such as a stable internet connection and sufficient bandwidth.
The main technologies involved in the process are codecs for compressing and decompressing video data, Voice over Internet Protocol (VoIP) for transmitting audio and media servers for managing group calls. A vital component to bring everything together is a cloud-based conferencing platform, which manages all the connections and provides a user-friendly interface.
Benefits of Video Conferencing for Businesses
Video conferencing offers a number of benefits for businesses, including:
Improved Communication and Collaboration
One of the biggest advantages of video conferencing is it offers real-time interaction compared to email or messaging. You don’t need to wait for an available meeting room, or manage the logistics of getting everyone to one physical location. You can simply send an invite link and within minutes, be collaborating on a project, making decisions and moving things forward.
Significant Cost Savings
Video conferencing enables businesses and employees to cut costs in a number of ways. This includes saving on travel expenses (including overnight accommodation for workers who live far away), as well as on office space and meeting room hire.
The software is relatively cheap to access, while it can even be free (if limited) for small teams or occasional meetings.
Support for Hybrid and Remote Working
Remote and hybrid working models simply wouldn’t be workable without video conferencing solutions. They help to ensure consistent communication across both in-office and at-home teams, keeping workers connected and preventing isolation.
Better Customer Engagement
It’s not just in-house business operations and teams which can benefit from using video conferencing technology. It can also be used to provide a better experience for customers and clients. For example, you can host virtual sales demos, consultations and support sessions.

Choosing the Right Video Conferencing Solution
It’s crucial to choose the right video conferencing solution for your organisation’s size, needs, and working style.
A good place to start is by looking at how your teams tend to communicate now. This may be one-to-one calls, large multi-site meetings or hybrid sessions requiring a more complex setup.
You’ll need essential features such as HD video and audio, screensharing, security, call recording and compatibility with your teleconferencing software of choice. In some organisations, extra meeting room hardware may be required – such as integrated cameras, microphones, and control panels.
Ease of use is key, so choose a solution your teams can adopt quickly. Finally, look for a provider that offers ongoing support and scalability to ensure your system performs reliably as your business grows.
