Video conference system purchase considerations
As an important part of a complete videoconferencing system, the performance of the videoconferencing terminal plays a decisive role in the application effect of the videoconferencing system. At present, there are various video terminals on the market, ranging from high-performance products for professional markets to low-end products with prices. Facing the complicated video market of the brand, users can choose what they want to buy and sell at a reasonable price. Simply speaking, they can be considered from the three aspects of product audio and video effects, their own application requirements, and the system application environment.
Audio and video effects are the most direct performance of a video conferencing product. It is also the most intuitive experience for users to use the product. Currently, there are "software" products and "hardware" products on the market. Although the two are similar in function, there are still some differences in audiovisual effects.
In terms of video and audio decoding capability, whether it is based on a closed platform or a development system platform, "hardware" products use dedicated DSP processors to perform corresponding codec operations, and their coding and decoding operation efficiency, especially coding efficiency is better than simply relying on The "software" product of the CPU is one of the biggest differences between "software" and "hardware" products. In addition, the current pure "software" products generally only support the application in the IP environment, and the general professional "hardware" products also support applications under various network environments such as ISDN, DDN, and satellite on the basis of IP.
Whether a product can be used satisfactorily by the user, in addition to the product's own performance, there is an application environment. In practical applications, due to the differences in the application industry and the environment, the user's focus on the terminal products should also be different. Generally speaking, excellent audio and video effects and stability should be the primary considerations for users when they are applied in government offices; when they are applied in the field of education, interactive real-time, abundant multimedia courseware transmission capabilities, and hypermedia Accessibility functions such as information interaction should be the focus of attention of users; in enterprise-level applications, due to the diversity of enterprise network environment and video products, the interoperability of products in enterprise-level applications and the richness of network interfaces should be highly regarded by users. .
In addition to environmental factors, users should also fully consider their actual application needs when purchasing products. With the maturation of videoconferencing technology, the industry trends that followed are overwhelming. However, some users have blindly pursued the trend in purchasing products, ignoring their own actual needs and causing a waste of capital. In order to ensure the value of the selected products, users should follow the following principles when purchasing products:
1. It is necessary to specify the application purpose, select the type of product that meets the demand on the basis of its own professional needs, and simply considering the cost or catching up with the trend is not desirable.
2. Considering existing equipment comprehensively, if the user already has certain communication facilities, the purchased products should be compatible with the existing equipment as far as possible, and make full use of the existing facilities so as to save input costs;
3, in addition to paying attention to the quality of the product performance, but also pay attention to product after-sales service, especially in the construction of a certain scale of the system, the product selection must consider the selected product manufacturers technical support capabilities, a variety of network engineering Networking experience, spare parts size, etc., to minimize maintenance troubles in daily applications.
