There are one or two things that are sure when it comes to video conferencing that meets all the customers … no more needs, no ready-made solution! Once there is an ISDN codec within the rollabout system, and do everything with you. Today’s customers require you to do video conferencing, but not the only means of video conferencing standards H.323 and SIP. Sometimes Skype, Microsoft’s Lync, etc., other Google hangouts, speak the loudest name because of the unified communication platform so much.

If the customer needs to build a video conference room, the first thing to consider is that in this room, hopefully there is a system that allows him to communicate no matter what it will be for its interlocutors and the systems they use. So the best way is to deal with audio and video separately: good video conferencing based on whether it’s standard or platform, with video capture devices, visualization, microphone and stereo audio. Once the outline, will be enough to all converge, allowing you to communicate with the outside world, usually a dedicated codec and personal computer.

The key factor to be analyzed is:

video

Audio

interoperability

connection

video

In a small room configuration is simpler and more compact: good monitor integrated speakers are usually the best choice. size? If you look on the TV monitor, you will choose the same: there is a default rule. The installation is a professional booth video conference complete, such as ezTalks Onion, or on the wall. Camera, rigorous motorcycle, installed above or below the monitor. The ezTalks uses as well as the lines we offer for Sony EVI, which gives quality assurance. I personally prefer the monitor, it can be better eye contact under the installation.

Eye contact is indeed the key word when it makes the video conferencing: the interlocutor must have the feeling of eye contact, and more to connect the camera to the monitor, the better the effect. Even the shooting distance has an important role: positioning the camera at least three meters away to fully reduce the shooting angle, as the observer’s point of view, to ensure a good visual contact. In salt medium or large, you need to make a wide range of video recordings for one or more additional cameras, and simple monitoring is replaced by a large, multi-monitor or video projector. Note that the latter surrenders: customers often relate to the image quality of the interlocutor what comes when the news host is seen from the waist box on the TV connection. That is fair, and for this reason, because the results of understanding the high brightness and high contrast are necessary.

Hall: Speaking of the quality of video recording, the light plays a fundamental role: to avoid direct light to reduce the shadow of the face of the participants. The rooms in the ideal world should have no windows so that ambient light does not affect the quality of the economic recovery, but here we are in reality, often customers are reluctant to change has been destined for video conference rooms. Therefore, it is necessary to provide window processing, and in the case of power failure is not the total, the organization of the room, so that the camera never turn the window. Leave the theory aside, the key concept is to avoid as light as possible to compare: more uniform, higher quality. In this respect, the walls of the room are preferably opaque and colored (green and blue is the best). In a strong color? Including white and black and face, endanger the quality of the video.

Audio

Let the audio play a key role. Feel good, make you feel good to see, if the audio does not understand, the success of video conferencing is more important damage. Audio broadcasts follow the rules of any other type of room, with more equipment: if the sound comes from, you see the same level of user perceived quality improvement through video conferencing. In medium or large rooms, the uniform sound spreads in the ceiling of the speaker, it is a good choice.

When the room is small, the interlocator is small, sitting around the table, the dedicated microphone is more than enough. They are integrated at the vertex of an equilateral triangle, such as three directional microphones that are the preferred unit of the cooperative microphone and the Speaker on the three sectors of 120 °, for split coverage (360 degrees in total), rather than a single microphone in all directions , Because the former can reduce the background noise from where the speaker’s speech field does not come. This type of microphone unit also integrates echo cancellation, which is necessary to avoid audio feedback when connected.

When the number of speakers is increased, the connection to the first second unit allows expansion of the shooting area. In many cases, in order to ensure the use of greater flexibility and solutions to provide greater value, it is advisable to provide customers with specific audio processors, which can provide an echo to eliminate.

Go up and go to the end of the microphone system for business video conferencing and the horizontal beamforming of the microphone array into a wide area of ​​24 microphones to 30 square meters. What solutions you have decided to adopt, have a good communication quality that is important for the microphone system and / or the audio processor is provided with an echo canceller, one for each microphone provided in the lobby. Features reduce background noise, equalize the gate and are very useful.

interoperability

Now that audio and video have been resolved, we can go back to the primary goal, that is, to meet the needs of customers, need a complete video solution. This is the mystery you started writing:

If the customer does not use any video communication system, the first step is to find a good video conferencing codec to ensure interoperability with the H.323 and SIP standards. The line of collaboration between ezTalks onion and AV records and MCU (multipoint) up to nine 60fps sites offers a wide range of options from the SD system to full HD.

If the client has already used the software for video communication, we will be connected to the previous paragraph to find your AV device connected to the PC. The sound is no problem: a simple interface on a PC with a video conferencing microphone or an audio processor. As for the camera, it can be connected to the video capture card computer DVI2USB 3.0.

These two environments can coexist, however, by determining whether two video conferencing coders are connected to the AV device, either the PC.

connection

When it comes to video conferencing, the important aspect is the connection of all the above devices; wired, wireless or via cable CAT depends on the distance involved and the available pipes. The last room to connect to the outside world, some open IT department, or better IP: firewall, NAT, proxy server, VPN and MPLS is the world’s key words you need to know the meaning and role.
