Video Conferencing

Your company is growing, offices are expanding across the world and your employees are asking for flexible work schedules, online meeting tools and more modern and effective collaboration spaces. While you know video conferencing can help address these requests and create better communication and collaboration across dispersed sites, the idea of implementing it seems a bit overwhelming.

This page breaks down the basics of video conferencing — from where it all started, reasons it’s worth the investment and some tips and tricks on choosing the right video conferencing solution for your business’s unique needs.

Video conferencing by the numbers

  • 80% of executives say turning on video for internal communications is becoming the norm; 84% say the same for external meetings 1
  • 87% more people use video conferencing today than two years ago
  • 75% of remote workers experience increased productivity and an enhanced work-life balance
  • 64% of companies have video conferencing setups in small huddle rooms 2

The Evolution of the Conference Call

The single most compelling reason to invest in communication technology is to be more productive. No one ever bought a fax machine to save on postage. Email wasn’t designed to save money on paper. Advances in technology for the office have always been about speeding up business.

The history of video conferencing takes us back to the late 1950s — early conference calling technology provided a way to host multiple people on a telephone call. The conference call was great for reducing air travel and speeding up decision making, but it relied entirely on audio and lacked the human element of an in-person meeting. Today, you can see the evolution of the conference call has taken two major forms:

Web Conferencing vs. Video Conferencing

Web Conferencing

On one side, web conferencing takes the traditional conference call and adds a layer of visual enhancement through a shared presentation. This offers meeting attendees the ability to view the same presentation slide deck and helps create the illusion that people dialing in are in the same room.

Video Conferencing

The other enhancements to the conference call came by way of video conferencing. Video technology focuses more on the face-to-face human connection and nonverbal communication to give everyone in the meeting both a voice and a face around the table.

As the evolution continued, we started to see the best aspects of web conferencing merge with the best aspects of video conferencing. Screen sharing was built into video conferencing services. Expensive on-premise infrastructure and telepresence rooms faded out in favor of more scalable, cloud-hosted huddle room solutions. And personal devices like laptops with built-in webcams and smartphones provided an easy way for anyone to join a video call.

Why Businesses Prefer Video Conferencing

Utilizing a simple, unified video conferencing solution within your organization not only enables you to communicate just like being there in person (minus the travel expenses), but it also enhances the face-to-face communication necessary for productive and authentic collaboration. Check out this guide for the top five reasons why businesses use video conferencing for their mission-critical meetings.

Video Conferencing Solution Breakdown

Today’s video conferencing solution comprises a central cloud-hosted infrastructure routing calls between personal device clients and meeting room device endpoints. But not all video solutions are created equal:

  • Some operate via a single data center, while others offer redundancy and reliability through a network of interconnected data centers.
  • Some design and build purpose-built meeting room hardware, while others offer recommended hardware kits of select third-party vendors.
  • Some are regionally focused solutions, while others operate a global scale for global communication and reach.

Meeting Room Video Conferencing Solutions

Cloud-based delivery models make it easy to turn just about any room with an internet connection and a power outlet into a high-quality video-enabled collaboration space. Here’s the equipment you need to hold a video conference:

Meeting Room Display

The availability of a display to connect people over video and enable screen sharing conference calls is critical. The general rule of thumb is, the bigger the room, the bigger the display. Many solutions will also support dual displays, allowing you to separate video participants to one display and presentation or content sharing to a second display.

Video Conferencing System

Composed of a high-definition camera and codec, a video conferencing system sends and receives encrypted video information and decodes it as live video on the meeting room display. The conference room webcam and codec can be integrated as an all-in-one system or separated for more customized integrations.

Conference Phone

A touchscreen conference phone is used to navigate your directory, control camera pan/tilt/zoom options and bring essential conferencing functions to your fingertips. Conference phones and conference call microphones purpose-built for video will feature echo cancellation, automatic gain control and automatic noise reduction to give meeting room participants crystal-clear audio.

App-Based Video Conferencing Solutions

People aren’t just meeting in conference rooms anymore. Video conferencing technology enables remote participants to work from home or join meetings on the go. Luckily, some video conferencing solutions offer a mobile app as well as WebRTC–enabled desktop and web apps for easy dialing. Today, a video conferencing application on your personal device with a camera and a microphone will give you everything you need to make and receive video calls on the go.

Video Conferencing Best Practices

From streaming social video content to real-time video chatting with loved ones, the new normal is the consumerization of video. But, like any technology, there are still human and environmental elements that can affect the success of a video call. Whether you’re joining your team’s weekly video standup or meeting with a job candidate for the first time through a video interview, here are a few remote employee best practices to ensure that your video call is as effective and productive as possible:

Use a Headset in Crowded Spaces

While you can meet through video anytime at any place, sometimes life’s distractions can get in the way. Wearing a headset in noisy, crowded spaces can virtually eliminate distracting echoes and help other participants hear you more clearly. When you don’t have access to a quiet space, use a headset so you and your colleagues can focus on what matters most: the meeting.

Mute When You’re Not Speaking

If you’re in a loud area and you don’t have access to a headset, one best practice is to mute yourself when you are not speaking (especially if you are on a call with more than two participants). This will significantly reduce background noise for everyone on the call.

Avoid Window Backdrops

Windows are wonderful for adding natural light to your office, but when used as backlighting on a video call, they can negatively impact the quality by giving you a harsh silhouette effect. Whenever possible, try sitting with your back to a wall rather than a window or try lowering the shades.

Opt-in for Meeting Recording

Recording online meetings usually leads to fewer side conversations and tends to allow teams to progress through their agendas more smoothly. Just make sure you let your colleagues know before you start recording a video call and share the recording with anyone who was attending.

Don’t Forget Your Far-End Etiquette

While video conferencing might make you feel like everyone is in the same room, remember to not turn your back to the screen(s) or block the view of the camera for “far-enders.” And remember to always say good-bye to the on-screen participants as you would to anyone else before leaving a meeting. It’s just common courtesy!

The Human Element

Just like talking face to face or through chat, video conferencing is just a normal part of your everyday workday. It isn’t rocket science — video technology is just another way you can communicate with people at the office. Put your best foot forward and focus on your meeting and your colleagues, not how you look on camera.

Optimizing Your Meeting Rooms for Video Conferencing

Many organizations have shifted toward more “open plan” offices and are investing rapidly to maximize office real estate by embracing modern technologies in their flex-use and standard meeting rooms. With the new affordability of video conferencing technology, many organizations are integrating video connectivity into every sized meeting room around the office.

The Mini Room

Mini rooms are among the fastest-growing meeting spaces today as businesses add inexpensive video conferencing solutions to their existing phone rooms and quiet rooms in search of a better return on these underutilized spaces. Mini rooms are the perfect place for one or two people to work together on a project or meet with an extended team over video.

Video Requirements: Look for a solution with a wide-angle field of view that is compact to fit the small space. Affordability and scalability are key components for organizations that will deploy five to ten mini rooms for every one full-sized conference room.

Room Size: 6’ x 6’ Seating: Up to 2
Display: Single display

The Small Huddle Room

Small spaces and huddle rooms are designed for smaller teams and subteams to meet for real-time collaboration. Add a smart video conferencing system, and you have a smart room for teams of up to six people to congregate for an unparalleled real-time meeting experience.

Video Requirements: Ease of use is critical for spontaneous collaboration in small meeting rooms. Look for a video solution with a small form factor and plug-and-play installation. Prioritize a wide-angle lens over zoom capabilities for small spaces.

Room Size: Up to 10’ x 10’ Seating: Up to 6
Display: Single display

The Medium Conference Room

Your typical conference rooms and boardrooms are ideal for larger groups to meet and build relationships through regular, face-to-face business conversations. Seating can range from as few as 6 to upwards of 30 people. Conference rooms generally require reservations to ensure availability.

Video Requirements: The increased size of the conference room adds a requirement for dual-screen setups that let you view video participants on one screen while sharing a presentation on the other. Larger rooms may also require more microphone pickups in addition to high definition cameras with optical zoom.

Room Size: 15’ x 30’ Seating: Up to 30
Display: Dual display

The Large All-Hands Room

Large meeting spaces like auditoriums, classrooms and all-hands multipurpose rooms are the largest forms of meeting rooms. Rather than a conference table, a typical layout will have seating positioned toward a dedicated podium or stage.

Video Requirements: Deploying a video solution that is rack-mountable and includes multiple device inputs and outputs — from cameras and laptops to DVRs and microphones — are key elements to look for in a video conferencing solution for the large all-hands room. Integration with panel manufacturers and third-party, integrated audio solutions may also be beneficial.

Room Size: 50’ x 50’ and larger Seating: 30+
Display: Dual display or larger

Selecting a Video Conferencing Solution

Before seeking out vendors and pricing options, the first step in any technology investment is to evaluate your own unique needs. When it comes to selecting a video conferencing solution for your company, it’s important to consider both your core team needs as well as the scalability and security requirements for your organization. The nice thing about a cloud-based video conferencing solution is that as those needs change, you can easily scale up or down to match.

Top 10 Questions to Ask:

  1. How many locations do we need to connect?
  2. Do we have remote or work-from-home employees?
  3. How many total employees will use the service?
  4. How many meeting rooms need to be video-enabled?
  5. What types of devices does the solution need to support?
    • Meeting room camera system
    • Mac
    • PC
    • Mobile/tablet
  6. Are security and encryption important factors?
  7. Can we replace audio-only and web conferencing subscriptions with video?
  8. How will employees use the service?
