The days of pixelated faces and choppy audio on video calls are behind us. Video conferencing has become the standard way businesses, schools and healthcare providers communicate across distances.

The global video conferencing market was valued at roughly $10 billion in 2025 and is expected to reach $12 billion in 2026, growing at around 12 per cent year on year (Precedence Research). Enterprise spending continues to climb as remote and hybrid work models become permanent.

Video conferencing saves time and money, improves collaboration and makes it possible to work with people anywhere in the world. This guide covers how the technology works, the main types, the benefits and the industries where it is having the biggest impact.

What is video conferencing?

Video conferencing is a real-time communication method that lets individuals or groups connect via audio and video over the internet.

Unlike a phone call, video conferencing lets you see the people you are talking to. That matters more than it sounds. Facial expressions, gestures and body language carry meaning that voice alone cannot. In practice, video conferencing works as a virtual meeting room where you can:

See and be seen. Facial expressions and body language add depth to conversations that text and voice calls miss.
Collaborate in real time. Share documents, presentations and whiteboards while talking, so decisions happen in the meeting rather than after it.
Connect across borders. Geography stops being a barrier. Teams in different countries, clients on different continents and students in different cities can all join the same call.

Whether you are running a team meeting, conducting a job interview, attending a virtual lecture or consulting a doctor remotely, video conferencing is the tool that closes the distance.

How does video conferencing work?

Video conferencing involves two steps: compressing and transferring.

Your camera and microphone capture video and audio. Codecs compress that data into small digital packets. Those packets travel over the internet, often through a cloud server that routes them to every participant on the call. At the other end, the data is decompressed back into visuals and sound, recreating the conversation in real time.

The result is something that feels close to being in the same room, with three advantages over a traditional phone call:

Engagement. Seeing facial expressions and body language helps you read the room, build trust and keep the conversation alive.
Visual aids. Sharing screens, documents and whiteboards in real time makes complex discussions easier to follow.
Remote participation. No travel, no commute. Anyone with a device and an internet connection can join.

Main components of video conferencing

You do not need expensive equipment to start. The basics are:

A device with a camera and microphone: a laptop, tablet or smartphone.
A display to see other participants (your laptop screen, an external monitor or a TV).
A stable internet connection with enough bandwidth for smooth video and audio.
A software platform that handles the call. Many options are available, from standalone apps to embeddable APIs like Digital Samba Embedded, which lets businesses build video conferencing into their own products. The key features of video conferencing software include screen sharing, recording, virtual backgrounds, breakout rooms and participant management; pick a platform that covers the features your team actually needs.

For better video quality, an external webcam can make a noticeable difference. See our guide to the best webcams for video conferencing for current recommendations, and our tips on home lighting for video calls for an easy upgrade that costs nothing.

Types of video conferencing

Video conferencing is not one-size-fits-all. Different setups suit different situations:

Point-to-point video calls

A direct video connection between two people. This is the simplest form: one-on-one interviews, quick check-ins, video banking or doctor-patient consultations.

Multipoint video conferencing

Three or more participants join the same call. This is the format most people think of when they hear 'video conferencing': team meetings, online classes, brainstorming sessions and client calls. Features like breakout rooms let hosts split larger groups into smaller discussions.

Room-based video conferencing

Dedicated conference rooms with specialised hardware: high-definition cameras, large displays and room-filling microphones. Used for executive meetings, boardroom presentations and situations where professional production quality matters.

Desktop video conferencing

Software that runs on a computer or laptop, letting individuals join calls from anywhere with an internet connection. This is the most common setup for remote workers and the format that grew fastest during and after the pandemic.

Telepresence video conferencing

High-definition visuals and spatial audio designed to create the feeling of being in the same room. Used for high-stakes negotiations, international collaborations and large-scale meetings where physical presence would normally be expected.

Benefits of video conferencing

Video conferencing is not just a substitute for in-person meetings. For many use cases, it is better. The role of video conferencing in business communication has grown beyond simple calls into a core tool for sales, hiring, training and customer support. Here is why organisations keep investing in it:

Flexibility and accessibility

Connect from anywhere, at any time. Remote workers, distributed teams and global organisations all depend on video conferencing to stay aligned without requiring everyone to be in the same building.

Cost savings

Travel, accommodation and venue hire add up quickly. Video conferencing removes most of those costs. For businesses with international clients or distributed teams, the savings are significant.

Time efficiency

No commute, no airport queues, no waiting for a meeting room. Meetings start on time and scheduling is simpler when nobody needs to travel. The time saved goes back into productive work.

Better collaboration

Real-time screen sharing, whiteboards, document co-editing and breakout rooms make video meetings more interactive than a phone call and, in some cases, more efficient than sitting around a physical table. Decisions happen faster when everyone can see the same information.

Lower carbon footprint

Fewer flights, fewer car journeys, less energy spent on office space. Video conferencing is one of the simplest ways for organisations to reduce their environmental impact without reducing their output.

Uses of video conferencing and applications

The applications go well beyond team meetings. Here is how different industries are using video conferencing:

Sales and marketing

Sales teams use video calls for product demonstrations, client pitches and account reviews without the cost or time of travelling to each prospect. Marketers run webinars, virtual events and video presentations to reach wider audiences.

For example, HubSpot, a global marketing software company, uses video conferencing extensively for sales demos, lead nurturing and customer support.

HR and remote recruitment

HR departments conduct remote interviews, onboard new hires and run team meetings across time zones, increasingly using AI tools for HR and AI in staffing to support these processes.

GitLab, one of the largest fully remote companies, conducts all interviews and internal meetings virtually by default.

Training and e-learning

Video conferencing platforms are used for virtual training sessions, workshops and educational seminars. Organisations can deliver interactive learning experiences to employees or students anywhere in the world, making continuous development possible without travel.

Coursera uses video conferencing to connect instructors with students globally, adding live sessions to its on-demand course library. For educators building their own virtual classrooms, Digital Samba offers a guide to virtual classroom equipment and the benefits of virtual classroom training.

Telehealth

Video conferencing has become a core part of healthcare delivery. Remote consultations, diagnostic assessments, patient monitoring and virtual therapy sessions are now standard in many healthcare systems. Telehealth platforms provide secure, confidential communication between providers and patients, improving access for people in remote areas or with mobility limitations.

Amwell, a major telehealth provider, offers virtual consultations for a wide range of conditions. For healthcare organisations building their own solutions, Digital Samba's telehealth video API provides GDPR-compliant, end-to-end encrypted video that can be embedded directly into patient portals.
