Comparison between VOIP and video intercom applications (1)

In recent years, with the gradual maturity of the IP video intercom technology, IP video intercom products have gradually been widely used. However, in order to save huge R & D costs, some manufacturers have transplanted the IP network telephone technology directly to the IP video intercom product, and consumers cannot identify the truth or false.

To this end, this article will elaborate on the IP network telephone technology and the IP video intercom technology respectively, and compare, to help consumers identify the authenticity of the IP video intercom products.

An IP network telephone refers to a system for Voice communication in a computer network with IP (Internet Protocol) as the network layer Protocol. The technology used is collectively referred to as VoIP (Voice over IP ), that is, the IP address transmits the voice. Because the computer network uses the group exchange technology, the data units transmitted by the computer are independent data packets encapsulated by the control part and the data part. Therefore, in a more general sense, VoIP belongs to the category of group voice communication.

Technically speaking, the IP network telephone is the result of the integration of the two mainstream technologies, IP-marked network segmentation and multimedia-oriented network service integration. With the development of group communication technology, integrated business communication technology, and IP communication technology, especially the Internet (Internet) with TCP/IP as the core protocol since 1990s) the extraordinary development in the world has led to the exponential growth of data services dominated by IP services. The exponential growth of data services has led to the vigorous expansion of IP networks and increased bandwidth, this effectively improves the quality of Internet transmission. In turn, it promotes the development of Internet services and the growth of the number of users.

Internet has moved from pure data services to multimedia communication, including sound and images. The boundaries between traditional computer networks and telecom networks have been broken. The first step for the Internet to enter the telecom service is naturally the most extensive IP-based group voice communication, that is, the IP network phone.
