Building intercom has been developed in China for more than 20 years, with rich and perfect product types. Although the semi digital and full digital TCP / IP products have been vigorously promoted in recent years, the mainstream products are still analog products, and the digital products are still expected incremental projects for various manufacturers, but more userhave accepted and used this more powerful product. At the same time, the trend of customer demand integration is obvious, building intercom products will achieve more functions.

Development characteristics of building intercom，So, what are the more obvious development characteristics of today's building intercom market?

Black and white video intercom is still the mainstream of the market, and the market growth of color video intercom is slow

The product life cycle of building intercom system in China's coastal developed provinces is in the transition from the growth stage to the mature stage, while the inland underdeveloped areas are still in the introduction stage. Due to the imbalance of economic development, the life cycle of building intercom is located in different stages in various regions of China, which also determines the mainstream of building intercom market. At present, black and white visual ordinary intercom has huge market potential in the underdeveloped regions in the market introduction stage, while color visual intercom has a suspicion of excess function due to its high price and slow market growth. However, the color visual intercom will be on the rise in the high-end residential or villa supporting. Generally speaking, the building intercom system has a promising future in the national market. The overall market is gradually developing from the East and south coastal areas to the West and North inland areas.

The general trend is from professional to civil, but the development of civil market is slow

In the early stage of building intercom system, the specialized and large-scale market with financial institutions, enterprises and institutions as the main force has become saturated. Moreover, the popularity rate of cities developed earlier in coastal areas has reached nearly 50%. Building intercom products have been used in newly-built communities without exception. The market has become saturated. The overall market has gradually developed from the East and south coastal areas to the West and North inland areas, and the professional market to the people Market expansion. As far as the current situation is concerned, the demand response of civil market only accounts for about 10% of the total market. Although the market potential is huge, its development is extremely slow. In addition, when the state cancels welfare housing distribution, the construction of residential quarters will devour part of the original share of the civil market. There is still a long process in the development of civil market, which can not be developed on a large scale only by one enterprise.

The buyer is not the user, the user is not the buyer

The building intercom system is mainly aimed at the connected communities, and the investors and builders of each community, i.e. real estate developers and engineering companies, are its target customers. The characteristics of "the buyer is not the user, the user is not the buyer" of the building intercom system are determined by the characteristics of its products. Although the single family building intercom market has a certain market 

potential, the main channel of the whole building intercom is still the real estate developers and engineers.

The way of building intercom purchase

In addition to the above five tips, we also need to know the following eight points to choose a high-performance access intercom system.

1、 Very strong stability

"Stability" is the primary principle for the selection of access control system. Mature products in the leading position in the world should be considered as much as possible. They have been certified by many authorities, have many typical users, operate normally for many years, and are highly recognized in the industry.

In terms of hardware, from controller to terminal identification equipment are mature and stable products. As the core of the system, the access controller needs to support the offline working mode. It must use flash and other non-volatile memory chips, and the information will not be lost in case of power failure or impact. Server and terminal identification equipment failure does not affect the normal operation of the system

As the management software that the system relies on, it should have a stable and reasonable database structure design. The real-time polling mode should be adopted between the system and the hardware to maintain and monitor the communication connection and address inquiry of the hardware and complete the integrity, reliability and consistency of the data.

2、 Very strong resistance to damage

Access control system is used to protect the safety of people and property, so the system itself must be safe. The high security here refers to the natural or quasi natural properties of the product or system, which should ensure the safety of the equipment and system operation and the safety of the operator. For example, the equipment and system itself should be able to resist high temperature, low temperature, damp heat, static electricity, interference, etc.; on the other hand, the access control and security system should also have the function of preventing man-made damage, such as: Anti disassembly alarm, etc.

3、 Excellent compatibility

In order to facilitate future upgrade, expansion and anti-interference considerations, it is recommended to select terminal identification equipment that conforms to international standards, rather than the wider the compatibility, the better. Some formats have some advantages locally, but they do not conform to international standards, which will bring troubles for future upgrading, capacity expansion and anti-interference. We should adhere to the principle of "practical, stable and in line with standards".

4、 Flexible scalability and economy

It is suggested that the authority of registration card should reach 30000, which can meet the requirements of most customers for storage capacity, facilitate attendance statistics and enterprise scale expansion. The main equipment shall adopt

modular design and advanced wiring mode. The future system expansion can be realized by upgrading the software and hardware, without making too big changes to the system, to maximize the economic principle, and the product shall be cost-effective.

5、 Powerful software management function

With the wide application of access control system, it is required to cooperate with attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage and online patrol。
