While many companies are starting to return to the office after a year of telecommuting, many employers and employees are striving to make working from home a permanent condition. The main reason both parties think this will work is that video conferencing systems have worked hard to improve session quality and ease of use.
Video conferencing system has been around for some time in various proprietary formats. Companies specializing in enterprise solutions have usually built these systems to connect conference rooms. Connections were made over a local network, and then, as a rule, over leased communication lines, if the connection was between different buildings. Network traffic was processed using mostly proprietary protocols and codecs, which are still the underlying architecture in use today.
What gadget needs to build a video Conferencing System?
Protocols handle streaming network traffic, while codecs handle encoding audio and video images into digital bits and bytes on the transmitting side, and then back to video and audio on the receiving side. This typically required proprietary cameras and microphones, dedicated servers, and server and often client applications that were also proprietary to the conferencing system.
Today’s cloud video services basically work the same way, except that they use TCP / Ip as their primary network protocol and a small list of standards-based codecs for conversion. Plus, their hardware support is usually open-source, which means you can use any webcam or microphone that works with your computing device.

SmartFrame captures everyone in seconds
Boost your productivity by instantly starting meetings. The Aver VC520 Pro 2 handle facial recognition to capture everyone on-screen in seconds and automatically changes frames when someone enters or leaves the room.
Match the System to the Room
Start with the room. A small huddle room for one to four people needs only a webcam and a small speaker. A medium room needs a wider camera and a better microphone. A large conference room needs a camera that can pan, tilt, and zoom, so it can show the speaker and the whole room. A camera that pans, tilts, and zooms is called a PTZ camera. Check the camera’s field of view. A wide field of view fits more people in the frame. Check the resolution. Full HD 1080p is the standard for most rooms. A higher resolution helps in a large room, but it needs more internet speed.
Sound Matters More Than Picture
Audio matters more than video. If people cannot hear, the meeting fails, even if the picture is clear. Pick a microphone that can hear everyone in the room. A table microphone works for a small room. A ceiling microphone or a set of microphones works for a large room. Echo cancellation stops the sound from bouncing back. A good speaker should fill the room without distortion. Test the audio before the meeting. Ask someone on the other end if they can hear everyone clearly. If the room has hard walls and floors, add soft furnishings or acoustic panels to cut echo.
Check Compatibility and Internet
Make sure the system works with the platform you use. The main platforms are Zoom, Microsoft Teams, and Google Meet. Some systems work with all of them. Others work with only one. Check before you buy. Check your internet connection too. Video calls need a stable connection. Zoom suggests around 1.5 Mbps up and down for an HD video call. A wired connection is more stable than Wi-Fi for a fixed room. If the room uses Wi-Fi, put the access point close to the room. Test a call at the time of day you usually meet, because the network may be slower when many people are online.
Set Up the Room Well
Place the camera at eye level. A camera that looks down at people feels distant. Face the light. Sit facing a window or a lamp, not with a bright window behind you. A bright window behind you turns you into a dark shape. Keep the background tidy. A plain wall or a bookshelf works well. Test the system before an important meeting. Check the camera, the microphone, and the speaker. Have a backup plan. If the video fails, join by phone. Keep the dial-in number and the meeting link where everyone can find them.
Frequently Asked Questions

Why is audio important?
If people cannot hear, the meeting fails, even if the picture is clear. Pick a microphone that can hear everyone in the room, and use echo cancellation to stop sound from bouncing back.
How fast does my internet need to be for video calls?
Zoom suggests around 1.5 Mbps up and down for an HD video call. A wired connection is more stable than Wi-Fi for a fixed room.
