Video conference system selection should pay attention to six points

All along, companies rely on traditional face-to-face meetings for information transfer, business negotiation, and employee training. Due to the geographical distribution of business scope, the carbon emissions caused by frequent annual trips have caused global panic. The low-carbon concept thus came into sight. How to make reasonable use of resources and reduce the number of trips at the same time while ensuring work efficiency without causing cost burden is an urgent problem for companies to implement low-carbon office.

With the rapid development of science and technology, in recent years, video conferences have rapidly “growthed”, replacing traditional corporate office models, which have greatly promoted the efficiency of corporate offices and helped companies embark on the road to digital informationization. The video conference replaces traditional inefficient business communication modes such as business trips, telephone calls, and E-mails by means of real-time, remote, and cross-regional communication. It breaks through the limitations of remote communication and enables “face to face” communication. Achieve realistic close-range communication. The emergence of videoconferencing saves the company's high travel expenses on the one hand, and on the other hand, it makes the company's meeting mode more flexible and also improves the office efficiency of the company and truly meets the "green office" requirements. So how can we build a videoconferencing system that suits them? Then you may wish to start from the following aspects.

1, select the industry's mainstream manufacturers, improve after-sale maintenance protection

Due to the huge number of “cakes” in video conferences and the variety of products of various manufacturers, the quality of products varies, and it is difficult for ordinary users to identify “authenticity”. Therefore, users should carefully consider the choice of manufacturers and should select mainstream manufacturers with stronger industry strength.

As we all know, video conferencing products are expensive, and in the event of a product system failure or secondary development of the system, it is generally difficult for users to handle it themselves. Therefore, it is particularly critical to select mainstream vendors. First of all, mainstream manufacturers have a relatively strong after-sales system that can quickly provide technical support, do a good job of product maintenance, help users solve problems, and ensure the normal operation of products. Secondly, mainstream manufacturers have the strength to continue to develop, help users to quickly upgrade their products, do a good job in product upgrades, eliminating the user's trouble in the process. Once again, mainstream manufacturers have done a great deal of successful cases and can provide companies with the most suitable solutions to help users better implement related applications.

2, according to their own network environment to choose the right product
At present, high-definition is no longer just a slogan, but has become the application trend of the current market, but if you want to achieve good video effects, you need to understand their own network environment. Any video conference needs a suitable network environment. However, in practical applications, most users' network broadband cannot meet the operating conditions of HD products at all, and achieving high definition requires at least 1 Mbit/s of bandwidth to achieve clear and smooth results. Not only that, users need high-definition display terminals while using high-definition products, which will increase the user's investment costs. Therefore, users do not blindly pursue high-definition in the purchase of products, according to the actual situation of their own bandwidth, choose the right product.

3, with clear and smooth audio effects to meet international standards

In addition to clear video effects, smooth audio effects are also critical. At present, most videoconferencing companies adopt the G.7xx audio coding specifications of the H.320 standard of the International Telecommunication Union ITU. However, because of their different environments and product differences, noise will be generated in the actual application process. In addition, techniques such as echo suppression, automatic gain control, and noise cancellation are also required to ensure clear and smooth audio effects. For large-scale communication vendors, GIPS audio technology is the best choice. This technology can automatically adjust the coding bit rate according to the bandwidth status, provide low-bit rate high-quality audio, and its core technology network adaptive algorithm, packet loss compensation algorithm and echo Eliminating the algorithm can solve the problem of voice delay and echo, providing users with perfect sound quality and bringing a clear voice call effect.

4, pay attention to the product's network adaptability and good compatibility

Usually when the user selects a product, if the video conferencing system and the supplier or the client's system are not the products of the same brand, it will cause many troubles in the convergence. Therefore, whether the video conference can be interoperable with other manufacturers' products becomes more and more people. Focus of attention. To have good compatibility, videoconferencing systems should adopt industry-unified protocols and standards, be open, and easily integrate with other vendors' products, including compatible applications such as VoIP, PSTN, SIP, and H.323. Not only that, users also need to pay attention to whether the product has good bandwidth adaptability when purchasing, even under low-bandwidth conditions, it can ensure the smooth and clear audio and video, packet loss compensation, RUDP technology, to solve the North-South network interconnection screen neck .

5, consider whether there is a powerful data function

All along, people are only paying attention to their "externality" in choosing videoconferencing products. They do not know that "inner" is also crucial, and they cannot be neglected. In the actual application process, users can provide rich data collaboration functions in addition to audio and video communication, and can conduct electronic whiteboard, file sharing, collaborative browsing, desktop/program sharing, text exchange, file transfer, electronic voting, and comprehensive recording of conferences. Remote camera control and other functions, and can support more than one person at the same time, this meeting mode can make the participants more convenient and thorough communication.

6, should fully consider whether the product has a strong confidentiality

Due to the complexity of current network operating environments, hackers and viruses are flooding, and product security should also be valued by users. In general, the product should have multiple encryption technologies to prevent malicious data attacks, support one-click recovery, and be able to meet the 7×24 hours unattended stable work, not easy to infect the virus, and will not cause a crash. Moreover, in the face of various types of firewalls, routers and other devices on the network, the system must be able to traverse the firewall and transmit data normally. Only with a high level of security can the meeting be conducted safely and smoothly.
