Analog intercom competition is heating up

The intercom system is a dialogue system for residents and visitors from residential communities, which is of great significance to the standardized management of the community and the security of the community. With the improvement of the residents' living standards, the management of the community is more and more standardized and rigorous. The community intercom system can fully improve the simplicity, convenience, and security of management.

After more than ten years of technology accumulation and development, voice intercom systems have become more and more fierce. The mainstream analog video intercom system manufacturers have become more and more fierce, with TCP/IP technology and With the gradual maturity of wireless digital technology, many manufacturers have applied such advanced technologies to building intercom products. Some manufacturers have introduced new digital audio consoles. The problems of traditional analog intercom systems are mostly concentrated in the networking part, and in the dong In part, its audio and video quality is still recognized by most users.

The design and development of digital systems is based on these advantages and disadvantages of analog systems, with targeted development of next-generation video intercom systems. The building still uses mature analog technology, while the networking part uses the mature TCP/IP networking technology. The main features of the digital system are as follows:

First of all, traditional analog buses are used in residential buildings and in the entrance line. Since the distance within the ridge is limited, the audio and video quality of this part can be well ensured, and this part of the technology is relatively Mature, easy to form a stable system.

Secondly, taking into account the use of TCP/IP digital transmission in the networking part of the cell, this solves the problem that the image and sound caused by the analog system's transmission distance are prone to interference. At the same time, the advantages of the digital system have been obtained in the networking part, and the performance has been greatly enhanced with higher cost performance.

In addition, due to the adoption of mature TCP/IP switching technology, the use of star-shaped structures and optical fibers effectively avoids the damage caused by lightning strikes, and the networking part is more stable and reliable, and maintainability is greatly enhanced. It is easy to solve the problem of setting up a multi-level management center in a large-scale community and locating a management center.
