18 video conferencing statistics for 2021

Remote work is on the rise. With growing need to stay in touch with and manage distributed workforces, organizations have greatly ramped their use of video conferencing solutions. This trend is clearly reflected in recent video conferencing statistics.

Video conferencing and remote work statistics

As remote work has expanded, so has company investment in video conferencing software to support effective meetings and collaboration:

1) There was a 500% increase in search impressions for web and video conferencing software in the first four months of the COVID-19 pandemic, per TrustRadius. (Source)

2) 60% of respondents to an Owl Labs survey reported participating in video meetings more often in 2020 than in 2019. That’s a bigger rise than reported for other workplace staples like email (50%). (Source)

3) A Boston Consulting Group survey found that 75% of respondents felt like they had maintained or increased their productivity after going remote. This trend is in part due to the convenience and efficiency of virtual conference rooms and video calls. (Source)

4) Per Buffer, 44% of employees say that at least some members of their teams now work remotely full time. Video conferencing enables the real-time, in-depth collaboration necessary for sustaining extended remote work. (Source).

5) 50% of people told Owl Labs that they will not return to jobs that don’t offer remote work options post-COVID-19, underscoring the importance of investing in the software and hardware necessary for holding virtual meetings with numerous participants. (Source)

6) Almost 80% of video conferencing participants join from a laptop or desktop computer, with phones and dedicated conferencing equipment the next most popular options. Tablets are less commonly used for remote collaboration and meetings. (Source)

Video conferencing and collaboration statistics

Video conferencing software provides the perfect platform for employee collaboration that boosts engagement and productivity.

7) 77% of remote workers say they are more productive when they work from home, according to CoSo Cloud. Fewer distractions plus the ability to interact with colleagues and clients via video conferencing software help explain this feeling. (Source)

8) Remote work is so good for focus that 76% of people say they avoid the office entirely (if possible) when they have something important to finish, according to Atlassian. (Source)

9) Over 80% of workers also say that remote work, with web conferencing software and video conferencing solutions for real-time communication, has increased their job satisfaction, per Velocity Global. The right video conferencing platform for collaboration helps strike a balance between productivity and happiness. (Source)

10) Buffer found that a majority (59%) of companies are within 2 to 5 time zones, which is a range that lends itself well to synchronous collaboration via video and web conferencing for real-time meetings. Asynchronous modes of communication like messages and email can fill in the gaps. (Source)

11) The same report revealed that having a flexible schedule (36% of respondents) was the most cited benefit of working remotely in the wake of COVID-19, followed by the ability to work from any location (26%) thanks to technologies like virtual conference rooms and web conferencing software. (Source)

Video conferencing productivity statistics

Video conferencing technology isn’t just good for employee morale and retention — it’s also a time and money saver for their employers.

12) Businesses save an average of $11,000 per half-time telecommuter per year, according to Global Workplace Analytics. The savings come mainly from reduced real estate footprints, higher productivity, and lower absenteeism and turnover. (Source)

13) The growth of video calls and web conferencing has made a lot of business travel nonessential, with 43% of frequent business travelers telling Oliver Wyman they expect to travel less even after the COVID-19 pandemic. That reduction represents big savings in company budgets (Source)

14) Nearly 9 in 10 employees state that video conferences reduce the time it takes to complete their projects, resulting in operational savings thanks to more efficient collaboration. (Source)

15) Companies that support remote work through solutions such as web conferencing see 25% less employee turnover and associated replacement costs, per Owl Labs. Considering it costs an average of $15,000 to replace just one person according to the Work Institute, turnover reduction is one of the best cost reduction strategies. (Source, Source)

Video conferencing growth statistics

Video calls won’t be going away any time soon, despite companies eyeing “return to the office” initiatives. Remote work is here to stay, and a distributed workforce will continue to need robust, dependable video conferencing software to support collaboration.

16) Global Video Conferencing Market Analysis noted that the video conferencing market was already on a high growth trajectory pre-pandemic, and has been forecast to grow at a compound annual growth rate (CAGR) of 12.1% between 2018 to 2023. (Source)

17) Global Market Insights now predicts CAGR growth of 19% between 2020 and 2026, reaching a value projection of $50 billion USD by 2026. (Source)

18) According to UpWork, almost one-quarter (22%) of the U.S. workforce, or over 36 million people, will work remotely by 2025. (Source)

The future of work will be remote, at least in part.

While many employees will undoubtedly return to office environments post-pandemic, the benefits of remote work are becoming clearer all the time. Tools such as video conferencing software enable employees to collaborate in real time without sacrificing productivity. On the contrary, video calls and web conferencing can make their users even more effective at, and satisfied with, their jobs.

Holy cows! (XoWS) Delivering the art of possible with video devices

Connecting video devices with XoWS

Cisco manufactures, hands down, best of breed Collaboration Video Devices in the world. Around April of this year, one of our Technical Leaders, Magnus Ohm, published a fantastic blog about xAPI-over-WebSockets (XoWS). It got our Python developers stoked! Connecting to our award-winning video devices using persistent web socket connections opened tremendous opportunities into delivering some fantastic use cases.

At Cisco, Technical Marketing Engineers help demystify complex architectures. We build out-of-the-box demonstrations and often times, we develop highly specialized proof of concepts. In this blog, I’ll discuss how the XoWS feature was used to articulate the “art of the possible” for one our customers.

The problem

While preparing for Cisco Live US in June, I was asked to help solve an interesting customer problem; manage multiple integrator video devices from a single pane of glass. If you’ve been surrounded by Cisco Collaboration as long as I have, then you may already be considering our Telepresence Management Suite application as the viable solution – remember Conference Control Center? What was so unique about this challenge then? Well, for one, the solution needed to manage several on-premises registered video devices, with the potential to control cloud registered (Webex) video devices as well; some potentially registered to different organizations or perhaps no call controller at all. Of course, these devices would be deployed across disparate networks and “Swiss cheesing” firewalls to access every codec’s web-based user interface was out of the question! The users needed a “bulk management” or “white-glove-service” portal of sorts.

Delivering the best solution

To get started, I was provided a handful of requirements –

(1) The users need to Dial / Answer / Hang-up / Transfer calls on the video devices

(2) They would like a preview of the Remote participant currently on a call

(3) 10 or more users would concurrently access this web page

(4) 15 or more video devices would need to be controlled from this web page

(5) Users would access this web page from different locations

(6) The video devices are hosted in different data centers

(7) There may be a mix of on-premises or cloud registered video devices

Surely, I could have wired up a single page application that could connect to every video codec the customer needed to control, but where’s the fun in that? How would you scale gracefully when you’re told ten or more users would tinker with fifteen, maybe twenty or more video devices from different physical locations – concurrently? Now before we go any further, let’s all keep in mind that this was a Proof-of-Concept to be built, not a TAC supported product. Just a creative yet scalable way to solve a problem. If you’re familiar with our XAPIs, or may have used the jsxapi library, your mind may already have connected the dots and creatively “solutioned” the problem, but wait! We had just released support for XoWS with CE 9.7.1! Wouldn’t that theoretically provide a scalable way to accomplish the mission?

Project scoping

Let’s dive into those requirements I mentioned earlier:

Requirement #1 (Need to Dial / Answer / Hang-up / Transfer calls ) – Whether you use the jsxapi library and connect over SSH, or decide to POST over HTTPS, this requirement can be easily fulfilled by understanding the codec’s xCommands. See API Reference Guide

For example, xCommand Dial Number: “12345” Protocol: H323

Eine Minute Bitte! Hold up! Requirements #3 (10 or more users with concurrent access) and #4 (15 or more video devices) suggest we would need a way to send these xCommands to multiple video devices and somehow avoid multiple users from sending redundant commands to the same codec from separate sessions!  Does that mean I need to consider managing user sessions, and, communication between these sessions?

Any web server with the right network access would address requirement #5 (Access web page from different locations) and if the video devices are on a routable customer network, requirement #6 (Video devices hosted in different data centers) would be met by this web server as well.

Requirement #7 (Mix of on-premises or cloud registered video devices) sounds tricky. At the time of writing this blog, we did not have the Cloud xAPI feature generally available for our cloud registered video devices. However, since we would deploy a web server for the user interface, why not develop “agents” or “connectors” that could access these video devices using the Integrator or Room Control roles!! Let’s also de-centralize the architecture for scale while we’re at it!

I’ve saved the best for last! Requirement #2 (Remote snapshots) – we do not officially support any way of providing snapshots of the “Remote” participant on a call, unless the call is “unencrypted” – full disclosure, this is a caveat and as such, I will not dive deeper into this topic. The objective here is to highlight the benefit of WebSocket support on our video devices!

Enter Project Codec Commander! A proof-of-concept powered by NodeJS, Redis and leveraging the XoWS feature available exclusively on Cisco Video Devices. For folks new to Cisco Collaboration, the word “codec” is often used to describe a video device.

NodeJS provides us the flexibility to consume it as a web server as well as an “agent”. It’s extremely easy to get started with NodeJS over just an Internet connection; check out Glitch! NodeJS also has several well-documented and mature packages for developing WebSocket client and servers, drivers for datastore connectivity, and your script can also be easily packaged or run as a “forked” process.

Redis is an absolutely fantastic in-memory data structure store. Some readers may argue a case for Kafka, RabbitMQ or others, but when asked to deliver a quick solution, I believe one should do so with the method they are most comfortable executing. In this case, Redis was used for storing JSON objects containing information about the code, but the real magic of commanding numerous video devices was best experienced when Redis was also utilized a message broker! (Illustration below):

What? Message broker? Yes! Think back to the requirements. We need a way to transmit commands from a user’s browser session, across and over to an individual video device, racked in a remote data center somewhere. This system would also need to accept xEvents from every video device, transmit the information back over to every active user’s browser, and manipulate the user interfaces. “Proof-of-concept” by definition is proof that a solution is viable in a very short amount of time and Redis provides the best-fit “Message Broker”, easy to consume on-premise, or inexpensively sourced from a cloud provider like Redis Labs.

Let’s get to the nitty gritty

Now that you have a view into the high-level architecture, let’s dive into some of the design details. (Refer to above illustration)

(A) Client Commander – This is a NodeJS web server that provides the following:

  1. Renders the web based user interface on any web browser that supports Web sockets, HTML5, Javascript with async/await and CSS
  2. Web socket server to orchestrate communications to/from and between multiple user sessions
  3. Redis Publisher to update data and send commands to video devices
  4. Redis Subscriber to receive notifications from video devices and other systems

(B) Message Broker – this is a Redis server that provides the following:

  1. Data store containing information about every video device (e.g. Serial #, Name, SIP URI, Display Name, Status etc)
  2. Pub/Sub broker sending/receiving data payloads across (A) Client Commander and (C) Codec Commander

(C) Codec Commander – These are individual NodeJS scripts that act as “agents”. Each agent is assigned to a particular video device for scalability and resilience. These scripts provide the following:

  1. Web socket client that connects to the codec and queries configuration data
  2. Subscribes to assigned codec’s xEvents and xStatus JSONRPC messages to monitor various states
  3. Sends xCommand and xConfig JSONRPC payloads to it’s assigned codec
  4. Redis Publisher to update codec data and send events/notifications from video devices
  5. Redis Subscriber to receive commands destined to the assigned codec
  6. 3 second preview snapshots using fetch()

The deliverable

In less than 2 weeks, XoWS provided us the ability to build a functional demonstration. Here’s a glimpse of an early release of the web interface:

Note: I was lucky to have Lauren & Peter help design and develop the user interface.! That’s not my area of forte and I cannot express enough, the importance of partnering with interface designers! No software demonstration or PoC can communicate its value proposition without an effective user interface! Thank you Lauren & Peter!

Deliver the art of possible

In conclusion, the XoWS feature provides developers with exceptional control and scale over Cisco video devices. Starting from release CE 9.7.1 and above, WebSocket connectivity on Cisco video devices  will provide persistent connection capabilities for your client applications. It’s availability as a protocol on our Collaboration Endpoint ecosystem creates invaluable opportunities for our customers and partners. XoWS is an extremely powerful differentiator that enables highly scalable and secure ways of codec management, control and transformative workflow integrations.
