Video Conferencing Hardware and Technology
The technology and equipment needed for a professional video conferencing system varies depending on the users' needs and the different spaces being used. However, some foundational devices are essential to video conferencing:
- Internet Connections: A good internet connection is required to communicate with others in remote areas, especially while streaming video. According to a study by the University of Chicago, most video conferencing platforms require an average of 1-2 megabits per second (Mbps) of download bandwidth and 0.75-1.4 Mbps of upload bandwidth for a single video call.
- Wired vs. Wireless: Do you want people to enter your conference space and physically plug into the system, or would you prefer a seamless wireless interaction? You can go both routes; however, there are some notable benefits to going wireless.
- Conferencing Software: A few trusted video conferencing software platforms offer the features and functionality for almost any type of video call. The most popular of those are Microsoft Teams, Zoom, and Google Meet™ software.
- Cameras: At least one camera is required for video conferencing. Most laptops and phones have these built into the hardware. However, external webcams and professional video conferencing cameras work as well, with features like speaker tracking and auto-framing for more high-definition video calls.
- Microphone: Again, most PCs have a built-in microphone that works great. These can be upgraded with higher-quality external microphones ranging from noise-canceling headset microphones to in-ceiling microphones for conference rooms.
- Speakers: For a single user, a simple pair of headphones or built-in laptop speakers may get the job done. But for group conferencing in larger rooms, you’ll need to consider room speakers. These can vary from built-in ceiling speakers to more flexible solutions such as Crestron Flex Pods for spaces that may change from meeting to meeting.
- Displays and Projectors: Video conferencing requires displaying the video on a screen. This is especially helpful for larger group conferences and when sharing informative documents. In most smaller rooms, a simple wall-mounted LED display will suffice. For much larger spaces like lecture rooms or conference halls, projectors are far superior to ensure the content is large enough to see.
By combining the technologies and equipment listed above, you can create the foundation of your professional video conferencing system. Depending on your room size and layout, you may even be able to kill three birds with one stone and opt for an all-in-one video conferencing system. Crestron Videobar 70 combines cameras, microphones, and speakers into one product.
That said, different types of system applications may call for additional hardware and software. Here are the main types of video conferencing systems applications and the different equipment associated with each:
- Desktop Video Conferencing: This is the simplest form of video communication requiring the least equipment, planning, and configuration. All you need is a laptop or PC with a webcam. You may need to install additional video conferencing software as well. But once the software is configured, you can conference with nearly anyone worldwide, including individuals and large groups.
- Native In-Room Conferencing (Conference Room Systems): This is the most traditional approach to video conferencing. In this scenario, there is typically a conference room designated for the video conferencing system. This room will contain all the technologies outlined in the section above.
- VR Video Conferencing: Virtual reality companies are investing more in conferencing applications to create collaborative virtual spaces where users can use unique avatars to show up in a more fun and engaging way. The most popular of these systems is typically self-contained in the hardware, which includes a headset and hand controllers. Once the user logs into the conferencing application, they can talk, listen, and present information.
While these applications are possible, traditional video conferencing systems are still the most popular. Most users will use a desktop conferencing solution or an in-room setup.
When it comes to both of those types of systems, Crestron provides a complete end-to-end solution for video conferencing. From large meeting spaces to conference rooms or small huddle spaces and BYOD scenarios, Crestron specializes in creating flexible room solutions to power your video conferencing needs with one touch.
