Beijing building intercom \ Shaanxi video intercom doorbell \ Principle wiring Guangxi building intercom system from a market perspective, the mainstream development of intelligent building intercom industry to a large extent subject to the real estate market, which caters to the real estate market throughout demand. In this area, although we can see some of the demand for professional intelligent intercom systems, such as medical call management system, as well as hotels and other service industries for interactive intercom system, but has been unable to form a scale of market demand intelligent building intercom industry for the majority of the newly developed residential district of the fact that the decision of the limitations of the development of intelligent building intercom industry. Intelligent building intercom system products and general consumer electronics appliances, such as home appliances, mobile phones and other products there is a difference in nature. Computers, mobile phones and other communications products have a common platform for information transmission and management, and home TV but there is a huge film, media and other information production and transmission system. Intelligent building intercom system development up to now, most of the practical function of the realization, or dependent on the different brands in the limited space to build up their own dedicated information transmission system. This model is largely broken do not see hope. It's fatal flaw lies not in limitation of information transmission and sharing, is not that the system is not standard, nor is the incompatibility of the system, but because it determines the consumer's disposable industry: we have only stimulate an already have this consumer groups because the system needs to update or upgrade will completely replace the existing legacy systems, in order to achieve a new round of consumption; Because special of the system, we can not even go to stimulate existing customers can enjoy the convenience upgraded service . In this sense, the intelligent building intercom industry to set its own market limitations. Building intercom system with the application of new technologies, has gone from analog to digital, from single function to diversify the evolution of functional integration. The current market, the user needs seemingly complicated can be met, such as integrated appliance control, police assistance, access management, information dissemination, remote meter reading, and so on. However, these concepts seem fresh and stylish, it is difficult to imagine the actual full of frustration and hypocrisy. Frustration is that some users are still far away from the real function, it did not form a real sense of value in use, even we can say that the consumer is no real sense of it. Hypocrisy is most manufacturers have introduced a variety of functions, its significance is only in response to market trends and casual manufacturing concept is not a departure from practicality. This is not to the actual needs of users for the purpose of unhealthy tendencies in damage to the interests of their users, but also doomed the intelligent building intercom industry immaturity. In today's technological advances, building intercom as the basic cell of civilian security products, the market has a full-featured, rich product that can adapt to different vertical markets throughout Dan needs. However, in the field of building intercom, individual manufacturers to cater to Chinese tastes, actually fabricated products with China playing a foreign flag. On the product packaging, packing spare no effort to publicize a "foreign element", while in product quality, service is completely behind the industry standard. Some companies even go for the benefit of swindling consumers, consumers will suffer. Such dry Ze and fishing practices although maximizes profits in a short time, but for a long time down the building intercom industry will lose credibility, consumers no longer believe in this industry. This is for the entire enterprise and industry are a huge loss. So, the whole building intercom industry has yet to be standardized. Especially in the building intercom industry standards have not yet unified, the cliché of service, after all, is building intercom brand rivalry "magic."
