With the development of enterprises, there has been an increasing number of branches. This makes contacts and communication between the various branches and headquarters become more important. Although the means of communication now extremely rich, especially micro-channel, both video capabilities, a lot of our work is to communicate through it. But there are also micro-channel inconvenient place, that is if you need to share internal documents of a company, and to discuss in front of this document, the micro-channel can not do anything. At this time enterprise video conferencing system is well made up for this deficiency.
Currently popular on the market for corporate meetings system has two types, one is similar to the mobile phone of Apple hardware and software are doing, we need to use the complete set its own system, the benefits of doing so is that the effect is guaranteed. The leader of these companies represent Polycom, domestic Huawei, ZTE, fish easy even do such equipment. To be honest, as long as the Polycom equipment used, to achieve its effects are very stunning, basic and talk face to face is the same. Polycom may stunning effect, while disadvantages are also evident. If the meeting need to share documents such as PPT, the sender need to prepare a laptop as an input, and the conference terminal needs to support dual-stream functionality, Polycom's new terminal point of such HDX7000 support dual streams. 
If this disadvantage is the inconvenience of use, and that the entire system be installed for at least two terminal double support plus a MCU, the price of at least 10 million, which is the cost of the barriers.
Based on this, some of the video conference pure software came into being. Such software is basically based on open source video conferencing architecture webrtc secondary development, the domestic video conferencing software basically this kind. Although webrtc provides a good framework, but it has a fatal flaw, is basically no echo cancellation, which at the time of the meeting is unacceptable. While controlling the echo cancellation, it is the secondary development of each of the manufacturers skill. After the trial, is doing the best foreign zoom, its official website is: https://zoom.us/ . And its price is one of the domestic manufacturers a bit,
This is its official price. But it does not support domestic open invoices, and there are not officially recognized agency, this is a small reimbursement for business obstacle. General corporate election that pro edition is enough, the host is initiating party conference, at headquarters on the line. Long time no restrictions in the meeting, the participants party of 100 people, of which 90% are able to meet the needs of the enterprise. But more conscience is that you can use for a free account, although the long 40-minute limit, but as experience its effects and functions are sufficient. There are various mobile phone system and zoom clients, for individuals to participate in the meeting is also very convenient.
After the software is finalized, the following is the hardware. Said earlier, webrtc there is a drawback is basically no echo cancellation. Although the zoom echo cancellation done a good job, but still have the hardware echo cancellation, in order to achieve the desired results. For the microphone, in fact, have a choice of a shortcut is Microsoft's skype for business website up, on top of Microsoft-certified hardware is very good. After I try many domestic manufacturers of goods and found that domestic manufacturers do have a very good all-directional microphone, the sound envelope factory is 
here you say that I am not afraid to advertise, although I did a Mao relationship with the manufacturers, I just share I tried the product. Specific products can you recommend yourself to contact the manufacturer.
Get the microphone, the camera relatively good choice, you direct election of Logitech on the right, you pick a psychological price to buy on the line.
Well, this software plus zoom microphone plus camera down, within a ten thousand to get the effect Well, Polycom has about 8 percent. There are advantages and zoom, is easy to use, because it is installed in the computer software, shared screen operation, ah, ah share documents, it is a basic function, very convenient. Coupled with the end of the phone software, no matter where, anytime, anywhere can participate in the meeting. This is now rapidly changing needs of the times.
