What Is WebRTC?

They use this technology more than you know

Web Real-Time Communication, or WebRTC, enables a standard that allows browsers to exchange audio and video. If you’ve heard of Hangouts or Hangouts Meet, Facebook Messenger, Dialpad, UberConference, Appear.in, and many other apps, you’ve probably heard of apps that use WebRTC to deliver voice and video. your browser.

WebRTC defines how a device’s browser can establish, manage, and terminate remote peer connections. The system includes support for cryptographic security standards and bandwidth management.

WebRTC Makes Web Conferencing Easier

If your browser supports WebRTC, you do not need to install plug-ins or download special applications to communicate with others. Don’t waste time downloading, double-clicking on files, or waiting for installation. Web audio and video conferencing becomes easier when your browser supports WebRTC.

Grant microphone and video access

However, to join a meeting, you must first allow access to your device’s microphone or video camera. If the real-time conferencing system needs access to one of these devices, it will ask you to “allow access” to the microphone or camera. You should only allow this access to trusted websites and services.

Which browsers support WebRTC?

Chrome, Firefox and Opera all support WebRTC. The team developing these three browsers is actively working to expand support for WebRTC. If you want a browser with WebRTC, one of these three would be a great option. Apple and Microsoft are also expanding support for WebRTC in new versions of Safari (macOS and iOS) and Microsoft Edge (based on Chromium). The website iswebrtreadyyet.com provides a quick visual overview of browser support for WebRTC.

How to test WebRTC

For a quick test of video conferencing using Web RTC, you can try the AppRTC video chat client powered by Google App Engine at https://apprtc.appspot.com/. Choose or create a random room name by following the link in your browser, then select Join to start the meeting. To see an example of how WebRTC works, join the same room name from a browser on another device. You can also adjust several settings using AppRTC parameters. Keep in mind that this is a demo and test application, not a complete web conferencing solution!

WebRTC Leak Privacy Issues

A WebRTC connection can expose a device’s web address. This is often referred to as a WebRTC leak because remote viewers can use the device’s Internet Protocol (IP) address. Even if you use a virtual private network (VPN) to hide your device’s internet address, in some cases a WebRTC leak can reveal your real IP address. This can be a potential problem as IP addresses are often used to identify a region, city, or internet service provider.

If your browser does not require WebRTC audio or video communication services, you can disable WebRTC. Otherwise, you can use a VPN to prevent WebRTC IP address leaks. Google provides a WebRTC Network Limiter extension for Chrome browser that gives you the option to protect your privacy.

For many, the benefits of fast, secure, real-time, browser-based communication that WebRTC provides may outweigh the privacy concerns associated with potentially leaked Internet addresses.

What Is WebRTC?

Web Real-Time Communication, or WebRTC, enables a standard that allows browsers to exchange audio and video. If you’ve heard of apps such as Hangouts or Hangouts Meet, Facebook Messenger, Dialpad, UberConference, Appear.in, among many others, you’ve heard of (or maybe even used) apps that rely on WebRTC to convey voice and video in your browser.

WebRTC defines ways that a browser on your device can establish, manage, and end a remote peer connection. The system includes encryption security standards, as well as support for bandwidth management.

WebRTC Makes Web Meetings Easier

When your browser supports WebRTC, that means you don’t have to install a plug-in or download a special application to communicate with other people. No more time wasted downloading a file, double-clicking on it, or waiting for it to install. If your browser supports WebRTC, web voice and video meetings become simpler.

Granting Microphone and Video Access

You will, however, need to allow access to your device’s microphone or video camera before you can conference. When a real-time conferencing system needs access to either of these devices, you’ll see a prompt that asks you whether you want to “Allow access” to your microphone or camera. Be sure to approve this access only for sites and services you trust.

Which Browsers Support WebRTC?

Chrome, Firefox, and Opera all support WebRTC. The teams that build these three browsers have worked actively to build out support for WebRTC. If you want a browser that includes WebRTC, any of these three would be an excellent option. Apple and Microsoft are also both building out support for WebRTC in Safari (on macOS and iOS) and the new version of Microsoft Edge (based on Chromium), respectively. The site, iswebrtcreadyyet.com, provides a quick visual overview of browser support for WebRTC.

How to Test WebRTC

For a quick test of video conferencing with Web-RTC, you can try an AppRTC video chat client powered by Google App Engine, at https://apprtc.appspot.com/. Follow the link in your browser, choose or create a random room name, then choose Join to start a conference. Join the same room name from a browser on another device to get a sample of how WebRTC works. You can also tweak several settings with AppRTC parameters. Keep in mind this is intended to be a demo and test application, not a full-fledged web conferencing solution!

WebRTC Leak Privacy Concern

A WebRTC connection has the potential to reveal the internet address of your device. This is often called a WebRTC leak, since your device’s IP (internet protocol) address is then potentially available to a remote viewer. In some cases, even if you use a virtual private network (VPN) to hide your device’s internet address, a WebRTC leak could reveal your actual IP address. This could be a potential problem, since an IP address often may be used to identify your region, city, or internet service provider. 

If you don’t need WebRTC voice or video communication services in your browser, you can disable WebRTC. Otherwise, you may prefer to use a VPN to prevent a WebRTC IP address leak. Google offers a WebRTC Network Limiter extension for use in the Chrome browser that offers you options to protect your privacy.

For many people, the benefit of fast, secure, browser-based real-time communications that WebRTC delivers may outweigh privacy concerns associated with a potentially revealed internet address.
