What's the difference between hardware and software of video conference system?

The difference between the two is mainly manifested in the following aspects:

Audio and video quality

1. Hardware video conference system: The audio coding adopts G.7xx audio coding specification of H.320 standard organized by ITU. The sound is lossy compressed.

2. Software video conferencing system: With the rapid improvement of PC CPU processing capacity, as long as users have a certain bandwidth, they can achieve clearer sound effects than hardware video conferencing systems.

convenient to use

1. Hardware video conference system: The hardware solution conforms to users' traditional usage habits, but with the popularity of the network, it is no longer dominant.

2. Software video conference system: On the one hand, with the popularization of computer and Internet applications, people are more and more familiar with and accustomed to computer applications; On the other hand, the software video conference system fully considers the convenience and friendliness of the product in technical design and function realization, so that most users can use it without special training.

price

1. Hardware video conference system: One-time purchase is expensive, and users will pay bandwidth access fees for a long time because they need certain bandwidth.

2. Software video conferencing system: The product price is only a fraction of that of hardware video conferencing system, or even lower. Renting is more affordable, and enterprises can make use of existing network conditions without paying high bandwidth fees.

Technology upgrading

1. hardware video conference system: the life cycle of hardware video conference system is about 3 years, and the technology is updated every day, so the special hardware equipment can't keep up with the development of hardware technology. Updating hardware or replacing a new upgrade module will be very expensive and inconvenient to implement.

2. Software video conference system: The application and function enhancement of any new technology can be updated for users anytime and anywhere, which is very convenient. The product upgrade price is much lower than that of hardware video conferencing system.

Network bandwidth adaptability

1. Hardware video conference system: It requires high bandwidth, and generally requires an independent line or private network above 384kb. Solving the firewall problem is too complicated.

2. Software video conference system: You can use the user's existing network environment. It is suitable for various network environments, various proxy servers and firewalls, and can meet the requirements of different network environments.

Data collaboration

1. hardware video conference system: the early hardware video conference system did not provide data collaboration function; At present, some high-end hardware manufacturers need to add special modules to the system and need additional PCs to support this function, so the system connection is complicated.

2. Software video conference system: with integrated data collaboration function, it can provide multiple functions such as document sharing, electronic whiteboard, * * annotation, text exchange, etc.

System deployment and expansion

1. Hardware video conference system: According to the requirements of MCU, the number of deployment points of hardware video conference system is relatively limited.

2. Software video conference system: According to the requirements of server and bandwidth, the number of users can reach hundreds.

Firewall support

1. Hardware video conference system: the ability to support firewall is very weak. It is strictly required that each terminal must have an external IP, which can directly access the Internet without going through a firewall.

2. Software video conference system: NAT firewall, proxy server and packet filtering firewall all have corresponding solutions. In most user environments, users can use it without any configuration.

light

1. Hardware video conference system: Most hardware video conference systems are used in fixed meeting rooms. At present, some video conferences on the market support desktop terminals, but these have great limitations in use, function and efficiency.

2. Software video conference system: You can use your laptop to hold video conferences through the Internet (or IP network) anytime and anywhere in your office, home, hotel or even Internet cafe.

Conference management

1. Hardware video conference system: the conference management function is simple.

2. Software video conference system: it can provide rich conference management and control functions, such as user database management, conference reservation, conference notification, conference statistics, conference agenda, voting, etc. According to various conference requirements, different conference types and conference control modes are provided.

Customization

1. Hardware video conference system: it can hardly meet the individual needs of any user.

2. Software video conference system: it can provide customized interface, function and customer brand according to user's needs.
