The sound is subject to loss of compression, in addition to technical indicators, but also need to have echo suppression, automatic gain control, noise cancellation and other voice processing functions to ensure that the system’s voice is more smooth and natural.

2, combined with real needs

In the purchase of video conferencing system, to the combination of the actual work needs of the unit and the network status of the branches and other factors to consider.Large conference room using high-definition conference equipment, medium-sized conference room using standard definition conference equipment, desktop users use software terminals, office users can use the software terminal, 3g mobile phone or telephone to participate in video conferencing. At the same time pay attention to the purchase of equipment and existing equipment compatibility, not too advanced can not simply save some of the outdated technology to save costs, should try to choose the mainstream technology on the market.

3, the election quasi-strength manufacturers

People in the pursuit of brand name is not without reason, because many times the brand is synonymous with quality, so in the choice of video conferencing system will often encourage you to pursue brand names, so manufacturers often represent the technical strength, rich experience, excellent after-sales service and other content, and video Conference system of computer technology updates soon, if there is no strong comprehensive strength, product replacement is slow, the user will not be able to get the service and security, this way can also be said to be in a sense increased the cost.
