Modern intelligent community becomes a hot spot with increasing demand for digital intercom

Building intercom is not only a kind of equipment that plays a role in building construction, but also called video doorbell. Strictly speaking, building intercom is a visitor management system. He is a user-friendly software, hardware and after-sales service. Manage guest operating systems. Digital building walkie-talkies, also known as smart terminals, are digital walkie-talkies designed using digital technology. The digital walkie-talkie digitizes the voice signal and transmits it digitally. That is, all the modulations on the radio's transmission frequency are digital.

As early as a few years ago, the real estate for digital video intercom systems has been quietly emerging across the country. For example, Anjubao launched smart terminals in 2003; Zhenwei completed NL hybrid multi-level visual non-visual networking systems in 2002. Including the E-3000 smart home system, C-5 smart community system, etc. It is understood that Guanlin developed the first generation of digital intercom products in 2004, followed by the development of second-generation and third-generation products. The fourth generation of products is already in research and development; and in 2004, the world also introduced a digital intercom system.

At present, digital intercom applications currently account for about 10% to 20% of the entire industry, and are generally located in high-end properties such as villas, luxury houses, and high-end residential areas. However, with the demand of the consumer market, the purchase of digital walkie-talkies is increasing every year. With the trend of industrialization, besides the application of the community, the development of the trend of the intercom industry can be clearly seen at many security exhibitions. For example, at the 2009 Shenzhen Expo, you can see that many manufacturers have smart terminal products, which also shows that digital intercom, digital home industry has gradually entered a mature stage.

The formation of digital walkie-talkies is an inevitable trend why intelligent terminals can form industrialization? Wang Weibing, deputy general manager of Xingtianxia Technology, said in an interview with Qianjiawang Security Network: “With the development of network communication, multimedia technology, and microelectronics technology in recent years, it has not only solved technical difficulties but also solved the problem of cost. Difficulties have made it possible for digital intercom to become industrialized, and people’s living standards have not improved, and their demand has increased. In addition to the basic intercom unlocking function, the intercom system needs to integrate SMS, announcements, photo/message, Electronic photo albums, security alarms, access control, smart homes, community shopping, information homes, and other functions and value-added services can only be satisfied by the powerful expansion of digital intercom. Digital intercom also solves the long-distance transmission signal attenuation of analog intercom. The number of users, the maximum number of accounts, the inability to call each other, the number of busy calls, etc. I think that digital intercom opportunities are moving toward smart terminals, and in the future, they will incorporate various intelligent systems in the user's home, eventually becoming a popular consumer product. Therefore, the formation of industrialization is inevitable."

The feasibility of technology and market demand are important factors in promoting the development of digital intercom. In addition, the digital terminal adopts integrated wiring, the route is relatively simple, and the grade of the real estate is upgraded. An Zhibao pre-sales general engineer Shi Zhi believes that more and more developers choose digital terminals. One of the important reasons is that the wiring is simple. Developers build digital communities. Many smart home functions can be done first, leaving the user to expand as needed. , so the overall investment will not be too high.

Standardization and unification is the key to the digital intercom industrialization The digital intercom is the trend of the development of the entire building intercom industry, and whether or not it can be standardized is a key issue. Intercom standardization has always been the focus of attention of the industry. Formulating national standards for digital intercom is not something that can be accomplished overnight. In 2008, the intercom industry established the Video Intercom Industry Alliance Summit Forum. At the time, two major resolutions were formed at the conference and there were two discussion topics. One is the development direction of the video intercom, which can be regarded as the type of technology that will be developed in the future; and the other is whether the video intercom can achieve the standardization and unification, and the standardization means that one host can use the extension of B. . In this regard, An Jibao's former general engineer Shi Zhi said: "Analog to digital is inevitable, visual intercom must take the digital. Because companies have a relationship of interest, so standardization is not easy to put in place, requires a transition, this transition can be It is the first way to realize the wiring.Everyone is taking the network and digitization, and the digital wiring is the same. The wiring may be unified, but whether it can be improved and standardized can be a long process.”

There are also many people in the industry who believe that prior to the formation of the national standard, we must first form an industrial technology alliance and establish coalition standards, and then raise the coalition standards to national and world standards. At present, the industrial technology alliance has long been mature abroad, such as the Bly-rayDVD technology alliance formed by Sony, Panasonic, Pioneer and many other companies. Through cooperation, the alliance's standards have finally become the world's standards.
