Moreover, digital is the future znlin positive 林楼宇 Intercom trend, it is no one can change the fact that the "digital home" market is gradually taking shape. The industry has the same view of the minority. development, research director Ltd. Shenzhen wave hit Shen Che stressed that "the future of smart home contains The concept of digital intelligent terminal products will be most concerned about the market. These products use embedded technology, more powerful hardware, software development more flexible, system more stable. Using standard Ethernet infrastructure, networking easier. With the growing importance of the home environment, such products is bound to be more widely accepted by customers. "Zhou Jun believes, when the market demand continues to expand, the digital znlin positive 林楼宇 intercom market gradually started The development potential of this market is still very large, will become the main battlefield of the next business competition. On the one hand, professional wireless communication upgrade from analog to digital is a major industry trend of technological development. With the popularity of professional wireless communication equipment, the problem of the shortage of frequency resources will become more prominent, while user demand is also rising, the industry will be more high-end customers tend to use digital products which achieve large mixed analog and digital networking Di Nike products to achieve a large mixed analog and digital networking. According to real estate within the district are different now, there may be characteristics of different needs, "part-time simulation that is all-digital" unity Installation is not good to meet the needs of users, so Di Nike introduced this mixed analog and digital technology innovation and large networked, the desire to achieve the same cell of analog and digital systems can be used simultaneously to meet the customized needs of users. Perfect Integration: smart home and smart city development to boost the advantages of digital video intercom and taste the product to a higher level of development, "2013 video intercom world market," the report of the survey, despite the weak global economic climate, but especially in Asia large-scale projects in the region (usually 50 or more items of the indoor unit) will drive the growth of the global market video intercom .IHS latest research report shows that Asia's massive video intercom system project is expected from this year to 2017, the growth of over 9.8%. Digital video intercom system benefits and taste, with the deepening of the wisdom of urban construction, znlin positive 林楼宇 intercom product mix toward higher quality, product selection increasingly being taken seriously. digital intercom and smart home combined intelligence community as the preferred combination intercom and smart home znlin positive 林楼宇, in a sense can be said znlin positive 林楼宇 intercom system from analog to digital development of the inevitable outcome, intercom digitization opens fundamentally intercom system bottleneck, making it possible to bind the smart home. The combination intercom and intelligent home systems further enhance the value-added space intercom system, cost the system has also been improved, so that the application of the new system more extensive future development direction of smart home should be based on practical, easy-based. With smart home technology continues to mature and supporting products, digital intercom and intelligent home systems inevitably achieve deeper cooperation on their function, within the broader scope of the combination, in order to achieve more digital intercom embodied the strongest features are the following fields: first, to increase the reliability and video, audio and data transmission quality of a traditional intercom system; second, to enhance the traditional intercom function, household intercom, visitors who capture, pictures messages, touch operation, have texture improving the human-computer dialogue; third, to strengthen the information services function in the information publishing, Internet browsing , to further enhance the interactive operation; fourth, providing a multi-system integration capabilities, and slowly become the control center elevator control systems, intelligent home systems, security systems; fifth, further to the wide area Internet, mobile phone network development 3C revolutionizing the trend, the Internet becoming more and more apparent. The continued integration of linkage intercom function, let the wisdom of the community building a more perfect, more intelligent. Redouble their efforts: technical innovation of digital intercom how companies should face the new trend compared to traditional analog intercom, advantages and disadvantages of digital intercom mining industry has long been out of it using an efficient digital transmission, can solve the problem of frequency congestion, and enables more data applications into a single wireless base station architectures were; but because of imperfect technology and the environment, digital intercom intercom is less stable than the simulation, which allows businesses to face the digital intercom technology When it looked different position. Breaking down barriers to make digital product development experts has been interest in the world are determined to become an expert in digital products. The exhibition brings Skyrise few bright spots, one of which was unveiled called "NPOE" power. This product provides the power to take the five-line power, do not like the original model a separate power cord cloth, so that not only simplifies the construction, but also to stabilize the Skyrise product system, the most critical is its low cost, to save construction costs; second, fiber to the home along with the development of national policies, Skyrise also adhering to the "fiber to the home, multi-network development", to borrow the carrier's carrier network, and through the ONU device access.
