【 Weak current College 】 purchase experience video conference equipment
Difficulty analysis
And medium-sized enterprises as an important component of the national economy, economic development and social stability of the pivotal role. In competitive pressure, the SME has begun to realize that effective communication on the importance of improving operational efficiency. However, due to the large number of domestic SMEs, the varying degree of information, and their IT investment cost sensitive, its system selection is limited by many factors.
According to a survey of China IT lab, small and medium-sized enterprises use video conferencing system exists in several aspects.
1. the "racking our brains," the problem is serious
IT projects of small and medium-sized enterprises and large enterprises are very distinctive compared to features, they usually pay more attention to production and sales, underestimate internal management of IT investments will have different considerations.
In recent years, the SME market maturing, the rapid development of industry and enterprise information level is low, the management behind a striking contrast, this does not suit to compel SMEs increased information technology hardware and software investments. In the information construction boom, some SMEs due to their business needs and not enough precise positioning, video conferencing system is not enough to know that result in investment behavior irrational.
2. cost control difficulty
Video conference system as a long-term investment, the need for business-to-use cost for a good control. Compared with large enterprises, SMEs and limited scale, the structure of a single, large enterprises often do not have the internal resources such as scheduling capabilities, lack of funds use strict comparison, randomness.
On the other hand, compared to large enterprises, small and medium-sized enterprises use video conferencing system less frequently, often dealing with some unexpected events, therefore the video conferencing application cost control difficult.
3. the system difficult to effectively safeguard
Through our investigation, many SMEs are not satisfied with the video conference system provider of the service, especially after the system online. This behavior is by video conference system provider strong psychological "alone". Because when a user in promoting the project, some video conferencing vendors to get orders in project negotiations initially very positive. But once the system is on the line, the system provider on the user system follow-up support maintenance service consciousness is not enough.
With the advance of Informationization construction, SMEs are increasingly aware of the importance of the service, the service has gradually shifted from the hardware maintenance, system maintenance, IT consulting, etc. Importance of SMEs, through advisory services determine the enterprise's own management status, current problems and create suitable for enterprise information construction process itself.
Selection procedure
Understanding of technical standards
And medium-sized enterprises in the selection of video conferencing system, you must rely on video conference system technical standards.
Currently, video conferencing vendors generally take the International Telecommunication Union (ITU) video coding standards, which efficiently saving video conferencing application valuable bandwidth resources has great advantages.
Where the MPEG4 and H.264 can not only be applied in a narrow band (bandwidth is less than 64Kbps), you can flexibly extend to high-quality, high-definition of broadband, this ensures that you can meet different needs of the actual application.
With the continuous development of the network technology, based on the MPEG4 and H.264 compression standard application has become increasingly common, incontestable become video products.
Inspection system architecture
Enterprise video conferencing system schema determines the stability of the system and can easily support extended bulk users. In General, the video conferencing system is composed of multiple function modules, whether the user wants to inspect the system adopts the international advanced distributed, modular, the bulk of the schema.
This distributed, modular system architecture features for future application provides powerful scalability and high configuration flexibility. SMEs in project planning and implementation can according to their own network size and business function needs to make a video conference system configuration deployment.
Furthermore, SMEs characteristics determine their system scalability, higher demand exists.
Consider network adaptability
Based on the IP network and the network of video communication quality varies widely. In General, small and medium-sized business users running mainly based on the IP network, so there is a higher network packet loss rate and a larger network jitter. These are in the process of using the quality of video conferencing especially sound quality have a greater impact. [fenye]
Therefore, the basic network features of small and medium-sized enterprises requires manufacturers to provide a network environment is highly adaptable product, instead of always requires the user to expand the network bandwidth and improve the quality of the network.
Video Conferencing vendors provide products are suitable for up to 10% packet loss rate of the network environment; changes in network bandwidth, ensuring the continuity of the sound, and supports a variety of file transfer, making the entire Conference intact; can allow multiple bit rates co-exist in the Conference. These are medium-sized enterprises in the presence of the product performance of factors must be taken into account.
In addition to the above factors, enterprises also need to know the following situation.
Manufacturers of video conferencing products can be compatible with other brand products; video conferencing vendor can offer the level of service is to provide stable audio and video transmission, videoconferencing systems in IP standard series, such as H.323 standard; video conference system supports multipoint Conference video conferencing multipoint join, whether users need additional investment in hardware and software; video conference system on the market the length of time, and the future of systems and technology integration, system provider is doing a more strategic planning. These SMEs video conference system selection is also important.
Specialists: choose the video conferencing equipment experience at seven
According to the domestic video conference system of practical application, we summarized the following seven experience for video conferencing systems engineering enterprise reference selection.
1. the network bandwidth to achieve 1M above
SMEs useHouseholds in the selection of former must confirm their network bandwidth enough run video conference communication. In General, SMEs to video conference system must achieve exclusive bandwidth 1M above.
2. in a real experiment in a network environment
In General, the programme providers in a specific environment for enterprise users of technology demonstration, almost all companies have the ability in exceptional circumstances make your own video products behave is watertight. Therefore, the user must be in their network environment to verify product performance.
3. understand the scheme of technology maturity
At present, the comparison of the leading on the market is based on standard solutions and H.320 is based on the H.323 standard solution. From the time perspective, the programmes based on H.320 standard technology relatively mature, wider, more full conference features, but its a one-time investment. The H.323 and H.320 programme compared to the investment is small, and the ability to easily transition to broadband or other, more convenient and efficient communications network. So the cost is relatively sensitive to small and medium-sized enterprises in the selection of programmes should be select support H.320/H.323 duplex mode products, so that in the existing infrastructure and future development can be balanced, could be longer protection of the established investment.
4. whenever possible, choose the simple operation of equipment
Small and medium-sized network environments generally not too complex, so the choice is simple, user-friendly video conferencing will be able to meet user needs. But it also can minimize business-to-video conferencing equipment use training costs.
5. focus on the practical use of equipment
Most manufacturers claiming that their video conferencing terminal can synchronize open dozens or even hundreds of road road video image, but this feature is not practical. The user session is not possible to listen to a lot of people talking at the same time, it can use spokesman video switch manner and different people video interactive, open multiple video screen is really just a waste of bandwidth.
6. the pros and cons of scalability concerns programmes
For small and medium-sized enterprises, the video conferencing system is a long-term investment, so you have to consider options for its scalability. Manufacturer independent development of video conference system based entirely on the implementation of software in General, you can easily create components or middleware products for secondary development and transplantation, and hardware products upon inputs expandable range are much smaller. Determined according to the needs of enterprises.
7. seek third-party agencies help
For small and medium sized enterprises Informationization, the enterprise itself is difficult to ensure that policy makers to make the right decision. Therefore, seeking external brain is to solve the problem.
Enterprises are to targeted advance information application, may wish to contact some professional advice, or looking for a video conference system expert help, so you can process the entire selection to better understand the needs, clear objectives, make the right decisions.
