Video conferencing is a technology that enables two or more people in different locations to meet face-to-face online, in real-time, using live video and audio over an internet connection. It’s how distributed teams collaborate across time zones, how companies run training without flying anyone anywhere, and increasingly, how business gets done as a default rather than an exception. This guide covers everything you need to know: what it is, how it works, what to look for in a platform, and how to run meetings people actually find useful.

What is video conferencing, and how is it different from a regular call?
This technology lets people in different locations see and hear each other in real-time, using a camera and microphone on any internet-connected device. At its most basic, it is a live video and audio link — sometimes called a video conference call — between participants who could be in different cities, countries, or continents. What separates it from a phone call is the visual layer: real-time video that allows participants to read body language, share screens, and collaborate on documents as if they were in the same room. 
The term itself covers a wide range. It can refer to a quick one-on-one video call, a structured business meeting between distributed teams, or a large-scale virtual event with hundreds of attendees. It is sometimes referred to as a video call, web conferencing, or virtual meeting — the terminology shifts depending on context, but the underlying technology is the same: audio and video streams captured, compressed, and transmitted over the internet in real-time. This is a technology used to connect people without geography getting in the way.
Video conferencing has become the default communication layer for most professional organisations. What started as a niche tool for multinationals managing people in different locations is now standard practice for teams of every size — from two-person startups to universities running virtual classes for 200 students simultaneously.
Why do organisations use video conferencing — and what does it actually solve?
Organisations adopt online meetings primarily because they save time and money. A recurring business meeting that used to require air travel now happens in a browser. The cost savings compound quickly — fewer flights, no hotel bookings, no venue hire, and no time lost to travel. For teams that span multiple time zones, this reduces the need for travel significantly and fundamentally changes how distributed work gets done.
But efficiency is not the whole story. The use of video conferencing also enables real collaboration — not just information broadcast. You can walk through a live document, see someone’s reaction to a proposal, or run a quick decision-making session together. This technology allows people in different locations to do all of that, and the use of video specifically (rather than audio-only calls) increases engagement and accountability in a way that is well-documented in workplace research.
Solveta, an international knowledge platform, uses ClickMeeting for everything from 1:1 sales meetings to masterclasses with 25 participants to webinars with 150+ attendees from over 75 countries. Their experience illustrates what scalable reach actually looks like: a small company reaching an audience that would be impossible to serve with in-person events, without an enterprise budget.
The benefits of these tools also extend to training and onboarding. Rather than repeating the same session six times across six offices, you record once and distribute widely. That is why this technology is now used to transmit everything from employee onboarding programs to live client education and product demos — it is a genuinely versatile communication layer.

How does video conferencing technology work?
This format is built on several core components of video and audio capture, compression, and delivery. Understanding how they fit together helps you choose the right equipment and troubleshoot problems when they arise.
The hardware side is what most people interact with first. You need a device with a camera and microphone — a laptop, desktop with webcam, or mobile device. The camera captures the video feed; the microphone captures the audio input. These are encoded into data by the platform software, which then uses the internet to transmit real-time audio and video to all participants. What arrives at the other end is decoded and played back instantly, creating the live experience of a shared room.
Modern platforms use adaptive protocols that adjust quality based on available bandwidth. When internet connectivity is strong, you get HD video and crisp audio. When it weakens, the system reduces the quality of the video rather than dropping the call. The video and audio streams are typically encrypted end-to-end. It is also worth knowing that video and audio streams used to transmit meeting content are separate from the platform’s signalling data — each is handled differently in the platform’s architecture.
The shift from hardware-based video conferencing systems (purpose-built rooms with dedicated equipment) to cloud-based, browser-accessible platforms is what made this technology genuinely accessible to businesses of all sizes. You no longer need specialised hardware — a mobile device or laptop is enough to join or host a call. AGH University of Science and Technology uses ClickMeeting for classes with up to 200 students, but also maintains two fully equipped webinar studios with professional audio-video systems for higher-production events. That shows what the ceiling looks like when you invest in dedicated video infrastructure.

“ Something we see regularly is that organisations pick a platform based on the video experience alone, and then discover they needed the infrastructure around it — registration, reminders, analytics, recording. The meeting itself is one part of the picture. At ClickMeeting, we have built the entire event workflow around the live room so that teams are not stitching together four separate tools to run one session. That integration is where real communication and collaboration at scale comes from. Tomasz Bołcun, Brand Manager @ ClickMeeting |
What should you look for in video conferencing software?
Not all platforms are built the same, and the features that matter depend on what you are doing with them. But there is a core set of video conferencing features every serious platform should cover — and some key differentiators that separate basic video tools from platforms built for professional events.
Start with the fundamentals. The core features include the ability to deliver high-quality video, handle the number of participants you need, and work without requiring attendees to install software or create accounts. Ease of use matters enormously: if people receive video links that require a download to work, you will lose a portion of your audience before the session even starts. Browser-based tools solve this.
Beyond the basic video call, here is what to look for:
- Screen sharing — for walkthroughs, demos, and collaborative document work. Present in virtually every professional session.
- Chat and Q&A tools — features that help manage participation without disrupting the session flow, especially as groups grow larger.
- Recording — lets people who missed the live session watch later, and gives you a permanent record of training content or decisions.
- Closed captioning — automated live transcription makes sessions accessible to more people and is increasingly expected in professional contexts.
- AI-powered features — smart noise cancellation, automated meeting summaries, and real-time translation are appearing in many platforms. Worth evaluating if productivity and accessibility are priorities.
- Advanced features for external events — registration pages, automated reminders, analytics, and payment integrations matter if you are running events for audiences outside your organisation.
- Scalability — some tools cap at 100 participants; others handle thousands. Make sure the platform fits your current needs and has room to grow.
Many video conferencing services draw a practical line between tools for internal team chats and platforms built for structured, external-facing events. Top video conferencing options like Microsoft Teams, Zoom, and Google Meet handle the former well. Platforms like ClickMeeting are built for the latter — where you need the full event infrastructure, not just a video room. Running client-facing programs, training series, and webinars calls for a different class of tool.
Is your online meeting setup secure?
Security concerns around online meetings became very visible in 2020, when uninvited participants began disrupting open calls — a phenomenon widely covered in tech press. It exposed something real: platforms that prioritised ease of access without matching it with proper access control created genuine security concerns for hosts.
The practical fix is straightforward. Protect every session with a password or a unique token — a single-use link that cannot be shared or reused. This eliminates most uninvited access. Strong platforms also let you control what participants can do: whether they can make video, share files, or turn on their audio. For any conference call involving sensitive information, those controls matter.
For EU organisations, there is a separate compliance question. Most well-known online meeting tools originate in the US and host their infrastructure on American soil. After the invalidation of the EU-US Privacy Shield in 2020, this created a GDPR compliance gap that organisations in regulated industries need to address. The practical solution is to choose a platform that stores and processes all data within the European Economic Area. ClickMeeting hosts everything in the EU and is fully GDPR-compliant — which matters both legally and for the confidence of your participants.
What equipment do you actually need for video calls?
Good news: the barrier to entry is low. Most modern laptops and mobile devices have a built-in camera and microphone adequate for standard calls. You do not need advanced video systems or a dedicated studio to get started with basic video calls.
That said, a few targeted upgrades make a real difference if you are hosting regularly or running client-facing sessions:
- External microphone — audio quality matters more than video quality. A poor microphone makes calls exhausting to follow. Even a basic USB microphone dramatically improves clarity over a built-in laptop mic, and is one of the best single upgrades you can make.
- Webcam — a dedicated webcam gives better resolution and framing than a built-in camera. For client-facing or high-stakes sessions, the difference is noticeable. Some external webcams also deliver high-quality video at 4K resolution for larger display environments.
- Lighting — a ring light or desk lamp in front of you (not behind) is a cheap fix that significantly improves how you appear on camera.
- Wired internet connection — stable is more important than fast. Ethernet eliminates the variability of Wi-Fi and is strongly recommended for hosts.
- Mobile phone as backup — for participants joining while travelling, a mobile phone with a browser-based join link requires no app installation and is all that is needed to attend.
Advanced video setups — like AGH University’s professional studio with multibeam microphones and background-changing systems — are built for consistent high-quality production at scale. For most teams, a good external microphone, a decent webcam, and a quiet space gets you 90% of the way there.
What are best practices for running productive video meetings?
Best practices for video meetings start before the session itself. Send a clear agenda in advance. This filters out people who do not need to be there, gives participants a chance to prepare, and keeps the call on track once it starts. Structure compensates for the things that are genuinely harder in a virtual meeting: reading the room, managing crosstalk, maintaining energy over a long session.
Think carefully about the number of participants. A call with 3–5 people works well as a working session. Add 15 and you need active moderation. Add 100, and the format is closer to a webinar — participants should submit questions via chat rather than speaking directly, and the host needs to manage the floor deliberately. Remote work contexts often blur these lines, which is why it helps to choose your format intentionally before sending invites.
Use video — and encourage others to as well. Research consistently shows that visible faces increase engagement and accountability. Calls where everyone has cameras off drift; people multitask and lose the thread. Make cameras-on the default rather than the exception.
Use the features that help. Run a poll for quick group input. Use chat for questions without interrupting the speaker. Collaborate on shared documents in real-time. Record important sessions so absent participants get the same content. And send video links rather than dial-in codes — every unnecessary step costs you attendance and arrival time. The best video experience is one where joining is frictionless and the session itself delivers enough value that people want to come back for the next one.
How does ClickMeeting compare to Zoom, Microsoft Teams, and Google Meet?
ClickMeeting, Zoom, Microsoft Teams, and Google Meet all deliver live video — but they are built for different primary use cases, which shapes what they are actually good at.
Zoom is the most widely recognised name in this space. It delivers high-quality video conferencing, handles large numbers of participants well, and has a feature set familiar to most professionals. Many video conferencing applications have converged on Zoom’s basic interface as a reference point. Its limitations for structured event hosts: limited built-in registration and automation, and US-based infrastructure that creates GDPR complexity for EU organisations.
Microsoft Teams is primarily a workplace communication platform integrated with Office 365. It is the default for organisations already in the Microsoft ecosystem — strong for internal collaboration, less suited to external events where your audience does not have Teams accounts.
Google Meet is the free option within Google Workspace — accessible, browser-based, and fine for small internal calls. For anything requiring registration, custom branding, or sophisticated audience management, it quickly reaches its limits.
ClickMeeting is built specifically for structured, external-facing events: client training, webinars, product demos, and educational programs. It delivers structured online events with registration pages, automated reminders, attendance analytics, recording, polls, and payment integrations via Stripe and PayU. All data is hosted within the EU. AGH University has used it for remote work and virtual classes with up to 200 students since 2016. Solveta runs international events with participants from 75+ countries on it. If you need more than a basic video call, it is a different category of tool.
Frequently Asked Questions
Here are answers to the most common questions about online meetings — from definitions and setup to security and platform choice.
What is video conferencing in simple terms?
Video conferencing is a technology used to connect two or more people over the internet with live video and audio, in real-time. It is also sometimes referred to as a video call, virtual meeting, or web conference. Think of it as a phone call where you can also see the other person, share your screen, and collaborate on documents — without anyone needing to travel to the same physical location.
What equipment do I need to make video calls?
To make video calls you need a device with a camera and microphone — a laptop, mobile phone, or tablet — a stable internet connection, and access to a platform. Built-in hardware is sufficient for most calls. To deliver high-quality video and crisp audio as a host, an external microphone and a dedicated webcam are worthwhile upgrades. A wired connection reduces the risk of quality issues during important sessions.
What’s the difference between a video conference and a webinar?
A video conference is typically a collaborative meeting where all participants can speak and interact freely — best for small groups. A webinar is a structured event where one or a small number of hosts present to a larger audience, who participate via chat or Q&A rather than speaking directly. Webinars include registration, automated reminders, and recording — features designed for external audiences at scale.
Is video conferencing secure?
Security depends on the platform and how it is configured. Every session should be protected with a password or a unique token. Good platforms encrypt the audio and video streams end-to-end and give hosts control over participant permissions. For EU organisations, GDPR requires that personal data is processed within the EEA — which rules out several major US-based platforms unless additional legal agreements are in place.
What is multipoint conferencing?
Multipoint conferencing refers to a video call with more than two endpoints — three or more participants connecting simultaneously from different locations. Modern cloud platforms handle this automatically through their servers. You do not need any special hardware; a browser and an internet connection are enough to join and contribute your real-time audio and video to the session.
What does “web conferencing” mean?
Web conferencing is a broader term that covers any online meeting conducted via a browser or internet application — including audio-only calls, screen-sharing sessions, and full video conferences. In practice, most web conferencing today involves live video and audio. The term is sometimes used interchangeably with online meetings, though technically it covers a wider range of formats.
What are the main benefits of video conferencing for businesses?
The main advantages for businesses are primarily practical: cost savings from reduced travel, faster decisions, and scalable content delivery for training and onboarding. The use of video rather than audio alone increases engagement and retention. For external events, it extends reach to audiences that would be impossible to serve in person. Solveta, for example, runs events via video with participants from over 75 countries — something that simply was not viable as an in-person model for a small company.
What should I look for in an online meeting solution?
Prioritise reliability, ease of joining, quality of the video and audio, and the specific features your use case requires: screen sharing, recording, polls, and chat for professional sessions; registration, analytics, and payment integrations for external-facing events. Also check internet connectivity requirements, the maximum number of participants supported, and whether the platform complies with your data protection obligations.
How many people can join a video conference?
This varies significantly by platform. Free video conferencing tools typically support up to 100 participants. Mid-range plans on major platforms go higher. ClickMeeting supports up to 10,000 participants in a single session. The right number also depends on format: a working call of 5 is very different from an event with 500 attendees, and different platform features are needed for each.
How does ClickMeeting handle online meetings and external events?
ClickMeeting is a browser-based platform built for both team meetings and structured external events. It delivers reliable video and audio with screen sharing, live chat, polls, Q&A, closed captioning, and recording — plus registration pages, automated reminders, attendance analytics, and integrations with Moodle, Zapier, Stripe, and major CRMs. All data is EU-hosted and fully GDPR-compliant. AGH University has used it for remote work and virtual classes with up to 200 students since 2016. Try it free for 14 days — no credit card needed, no download required.
