Building intercom is a security system. In a multi-storey or high-rise building, a management system that allows visitors, residents and property management centers to communicate with each other, exchange information, and control access to the community's safe access routes is commonly referred to as a building intercom system.
Domestic development trend
1. The building intercom system is forming a relatively independent industrial sector
Although the development of the building intercom system in China is not long, its market prospects are promising. So far, manufacturers have soared to about 250 companies. Building intercom and television monitoring, anti-theft alarm, access control management, intelligent parking, etc. together constitute the security industry. Due to the progress of society, changes in human life patterns and thinking patterns, coupled with the economic development, the differentiation of social strata has intensified, and social security conditions are not optimistic, all of which have a great role in promoting the development of the security industry.
2. Increased sales volume, serious bidding industry, reduced profit margin
A company in the building intercom industry declined sharply at the beginning of the year. Although the bidding behavior can increase the overall sales volume, the profit reduction rate is also very large. Some manufacturers are aware that the bidding industry will bring serious consequences without any living space. Therefore, they are committed to improving product quality, increasing investment in after-sales services, and accelerating the progress of product development. The building intercom market segment gradually takes shape.
The building intercom system has been used in Europe and the United States, Hong Kong, and Taiwan for nearly 20 years. Since 1992, manufacturers of building intercom systems in foreign countries have successively opened up markets in China. So far, there have been nearly 10 foreign brands on the mainland, and domestic building intercom companies have developed rapidly. The market share of domestic building intercom systems is about 80%.
