Looking at the development of the intercom market of buildings, China's building intercom products can be divided into four stages from the development of technology, namely non-visual intercom - black and white video intercom - color video intercom - home intelligent terminal (Also called digital video intercom). Early building intercoms were generally just to ensure the safety of the living environment, that is, “security-type building intercomâ€. However, with the continuous improvement of residents’ community security management and property management requirements, simply providing simple security functions can no longer meet intelligence. The need for continued development of the community. As a result, home smart terminals emerged and gradually became industrialized. The technology upgrade goes beyond the original concept of intercom. In the late 1980s, the function of building intercom was relatively simple. Only simple functions such as talking and unlocking were used. The occupants mainly judged and decided whether to open the door according to the voice of the visitor. And the entire market is also small. Subsequently, video intercom was born, the system increased the camera, display, sound, images, etc., the function began to diversify the direction of development, video intercom gradually expanded and become the market mainstream products. In recent years, with the rapid development of digital technology, information dissemination technology, mobile phone short message publishing technology, video messaging technology, ip phone technology, and elevator linkage technology have also been widely used in emerging networking intercom systems. Since 2004, home smart terminals (digital video intercom) have been used in some high-end real estate applications, and manufacturers have paid attention to their beautiful appearance and unique shapes. They have developed information release, image capture, image storage, remote meter reading, and home appliance control. Touch screen and other functions, which goes beyond the original building intercom concept, is also a building intercom system that has been integrated with Internet technology.
The demand of the market has led to the industrialization of smart terminals. In addition to a few single-family homeowners, the market will be networked so that all households can make calls, talk with owners and property, and publish public information. This is also the development of China's building intercom products. trend. With the development of the real estate industry, large-scale, high-end real estate has also gradually increased, many cities in the thousands of apartment types of real estate can be seen everywhere, before it is more than a thousand of the real estate are difficult.
New types of properties such as spring bamboo shoots, considering the safety of the community, high-end factors and other factors, many new real estate are considered to build home smart terminals, which greatly strengthened the community's security and technological content, real estate prices have also risen by a grade . According to visits, the current average household investment in home smart terminal systems is around 2,500 yuan, and users can choose their own home smart terminals according to their needs. As early as a few years ago, many brands such as Andromeda, Guanlin, Anjubao, Zhenwei, Jiale, etc., were keenly aware of their business opportunities and launched smart home terminals (digital) represented by smart terminals. Video intercom). The combination of visual intercom technology and smart home will undoubtedly accelerate the development of the intercom market in depth.
Good Opportunities and a favorable digital development platform At the end of last year, the Ministry of Industry and Information Technology issued a notice requesting that, starting in 2011, the model approval of analog walkie-talkies be stopped and digital walkie-talkies should be replaced by analog walkie-talkies within five years. At the same time, the 150-MHz, 400-MHz channel spacing was adjusted from 25KHz to 12.5KHz, which doubled the frequency utilization of radio spectrum resources. The issuance of the notice by the Ministry of Industry and Information Technology is a new opportunity and a new challenge for the building machine industry. In September 2008, the “Digital Walkie-talkie Alliance†(“DRAâ€) was established in Shenzhen to provide a platform for information sharing, training, exchange, and cooperation for the digital development of the industry, which promotes the standardization of enterprises and the effective use of market resources, effectively promoting The development of digital walkie-talkie industry in China.
The industrialization of smart terminals has provided manufacturers with new opportunities for development, while at the same time strengthening market competition. At present, in the coastal and developed areas, home smart terminals have been more and more recognized and accepted by developers. Although there are still many ways to go digital, there has been a convergence of intercom technology and smart home technology in recent years. It is enough to prove that the intercom industry is constantly maturing and moving in the depth direction.
