Every year, the popularity and variety of uses for audio-visual communication increases. Delivering services online has many benefits for industries like healthcare and others. The intensity of the shift towards online services accelerated when Covid-19 began affecting all our lives.

What’s the easiest way to implement a video-conference service in your product or organization?

WebRTC may be the answer to this question.

Many of the worlds largest technology firms, including Apple, Google, and Microsoft, endorse WebRTC as a global standard. Its a free, open-source technology that allows you to add audio-video capabilities to many types of products.

WebRTC offers voice calling , video conferencing and file sharing in real-time with no external applications or extra browser plugins.

Some of the most popular, high-quality products that use WebRTC are Google, Facebook, Amazon, BitTorrent and Discord. Our company,, also uses this technology. You can see an example of its use in our audio-video application called Captio (

Why is WebRTC good for businesses?

Use of the peer-to-peer connection model is what makes WebRTC a powerful technology.

Peer-to-peer connection (or P2P) is a communication model where every single device in the network is equivalent. Every user connected to the P2P network can send (as long as they have the appropriate permissions) and receive data.

Each device connected to the network may act as a server and a client too. This combination means its possible to download files and share them with other computers on the same network in parallel. Within the communication process, the external server role is minimised. The external server is only needed to establish a connection between two devices. Once thats done, the servers part is complete. Users then send data to each other directly , which minimises delays. WebRTC is a real-time communication technology because P2P reduces data transmission lags, and latency is almost imperceptible.

Peer-to-peer provides so much more in addition to this.

What are the advantages of this technology over the competition?

The benefits of WebRTC are so very numerous that, in the field of streaming audio-video, theres almost no legitimate competition. Now lets go through the WebRTC benefits and see what they provide in practice.

WebRTC is free

WebRTC is open source, which means that developers and companies worldwide support this technology by getting involved in its development. Due to this, WebRTC is getting better and better every year. After all, free and excellent quality means many providers - such as Twillio, Quickblox and Agora - use WebRTC to help deliver their services.

WebRTC has great support from the developer community

WebRTC is open source and that means that developers and companies around the world support this technology by getting involved in its development. For this reason, WebRTC is getting better and better every year. After all, free and very good quality means there are many providers like Twillio and Agora who can help deliver this service.

Any device with access to the most popular modern browsers can use WebRTC. The technology does not cut us off from Mac , Windows , Linux or mobile system users. We are also not limited to specific browsers. Although WebRTC does not need external applications or plugins, we can create them if we wish.

WebRTC is secure

WebRTC can uphold the highest security because there is no intermediary layer to access the transmitted data. After establishing a connection, data transfers between the connected peers only. Additionally, before using a physical device such as a microphone, WebRTC needs to get permission from the user. Finally, the entire connection is encrypted so only the conversation participants can read it. If you are interested in HIPAA , some WebRTC providers like Twilio will provide this as well. Get in touch with our team if you want to learn more about HIPAA compliance in audio-video products.

WebRTC offers a variety of features

WebRTC not only allows you to stream data such as video and audio. You can send messages , share a users screen , and even transfer files.

Low latency

Reducing lag between users is one of the primary challenges when creating a video chat. As WebRTC eliminates the intermediary during a conversation, lag is minimal and, in most cases, undetectable.

Adaptive to the internet connection

Stable, fast internet is not available everywhere. In the case of video chat, WebRTC can negotiate the size of the data sent. If the connection quality deteriorates, we can lower the data rate to avoid any interference.

High video quality

WebRTC uses codecs partly based on those used in Skype, such as iSAC, iLBC, Opus, and VP8. Consequently, 4k video and stereo audio streaming up to 48kHz are possible, meaning sound can contain the full human auditory range.

WebRTC provides great capabilities in times of online-first businesses.
That's why we decided to use it in Captio, our video-chat project.

How WebRTC is used in business products

Telemedicine is an approach that makes healthcare cheaper and more readily available to patients.

According to an Accenture study, 7 out of 10 patients prefer a health provider that offers interactions online.

Video appointments with a doctor are faster than an in-person visit. At the same time, they improve the options available to those for whom a regular doctors visit requires great effort or a long journey.

Telemedicine is especially valuable when life gets busy. Concerns can arise, such as wasting time in a physical or virtual queue or perhaps being near many unwell people. WebRTC means more patients get appointments, and the waiting times reduce.

Financial Services

Research shows companies that support customer relations via many contact channels can retain 89% of their customers.

Today, in the era of widespread digitalisation, it's unwise to neglect remote customer service.

Thanks to easy screen sharing, consultants can now give customers a live demonstration to familiarise them with the financial organisations products and services. Whats more, one-to-one video calls help engage customers, build trust and provides a personalised experience with a human touch. For people who liked in-branch customer service, this goes a long way towards making up for whats missing. Its also appreciated by people with a preference for digital interaction. Video support sessions are a convenient way to fill gaps in understanding financial self-serve tools offered by banks, mortgage brokers, insurers, investment managers and other financial sector businesses.

The premium service standards, vital to banks and other financial businesses, disappear when connections lag and become unstable. WebRTC helps eliminate latency and provides the best connection quality possible, so these companies can continue to deliver a high level of customer service.


Nowadays, in times where remote schooling is widespread, a WebRTC-based solution can help students participate in their classes. However, remote teaching can lead to feelings of isolation, and video classes often bring welcome relief from this experience. Additionally, feelings of isolation disappear when video conferencing

allows for meetings between students and teachers located further apart. Such an opportunity is much less easy to arrange when gatherings must take place in a physical location.

With WebRTC, students can focus on the topic of the lesson without being distracted by technical glitches. The great video quality allows you to see whats on the school blackboard and, for the teacher, what a student is pointing to in their notebook.

The ability to stimulate engagement and collaboration between students and teachers is perhaps the most significant benefit of video conferencing in education. As a result, students may become more motivated and interested in their studies.

In addition to audio and video, screen sharing is a valuable option. This capability enables creating a virtual class with additional features such as a virtual blackboard or a worksheet in a web browser where the instructor can monitor the progress of the students.

Customer service video calls

Customer service sessions over video give the customer a great feeling. After all, they have just had one-on-one attention, even if just for a few minutes. Also, if it's needed, both parties can present using screen sharing or a video camera. This raises the customer's sense of the quality of the service and can p;rovide a feeling of empowerment.

It is much easier to solve these problems when a specialist can visit in person. Unfortunately, this support comes at a much higher cost. Also, discovering when the client is home, and the specialist is available is often inconvenient.

Once again, real-time video conferencing reduces costs and makes it much easier to locate the problems source and then provide solutions.

Field Services

Production processes run smoothly only when the machinery involved works as intended. Picture an oil rig or a sophisticated manufacturing plant. Often, complex mechanised processes like these need constant attention from specialists who fix problems as they arise. Usually, there are fewer specialists than is

necessary to keep production optimal the whole time.

A few years ago, Google released a product named Google Glass. The manufacturing sector embraced it and, combined with WebRTC technology, it allowed experts to instruct technicians in real-time as complex manufacturing processes were performed. Google Glass is well-suited for those who want a hands-free computing assistant in industrial settings. Google Glass is ideal for picking up items and doing intricate assembly tasks. Other suitable settings for hands-free work that smart glasses can boost are quality assurance and in-person instruction.

Of course, Google Glass is not an essential element. New applications created using WebRTC alone allow less experienced staff to solve comparatively complex problems.


People love playing games and sharing emotions with friends and acquaintances. Games are fun and big business too. Nowadays, the gaming industry is associated with large amounts of money, and competitive games are the focus of much of it.

The games typically feature high-speed, dynamic gameplay involving many participants, where a technical delay is unacceptable. Competing groups routinely perform coordinated actions while relying on delay-free communication, especially by voice. That is why real-time communication with WebRTC is the standard for this industry.


There are two different ways to implement WebRTC. The first one is through a browser and the second one is within a mobile application.

The browser is the default implementation of WebRTC, and it works with all the most popular internet browsers.

What browsers is WebRTC compatible with?

For desktop:

webrtc browser support


For mobile:

mobile browser support

Mobile platforms support browser-implemented WebRTC, with some limitations. The default way of consuming content on mobile devices is through applications.

The mobile application has many more possibilities than the web application. It can use components such as navigation, notifications and more. Moreover, even though all of the browsers listed officially support WebRTC, not all of them fully exploit the potential of the technology.

If we want our product to offer the highest standard on a mobile platform. In that case, the best solution is a mobile application. Additionally, you can take advantage of WebRTC vendors like Twilio, Agora or Quickblox, which greatly facilitate the implementation of such a service in your application.


WebRTC is a fantastic technology that has proven its effectiveness many times. It is an incomparable tool offering the highest security standards and perfect connection quality. In addition, WebRTC has been on the market for many years, so many solutions are available to help you use this technology to the best effect.

Having read this article, we hope you can now see the benefits of using this technology in your business.

Part one ends here but the subject continues in part two. I invite you to the second part where I look at WebRTC using a more technological perspective.
