The combination of building intercom and application in the smart community has become the industry's development trend. Smart community services make full use of advanced technologies such as the Internet of Things, cloud computing, 4G, and put forward the ideas of community integration services and owner integration services. Create a community service management platform that integrates cloud access control, cloud intercom, community shopping, community information, video surveillance, and home intelligent control, and realizes intelligent and convenient management of the community.

Building intercom performance in smart community construction:

1. Actively participate in the digital wave

Digital technology is an inevitable trend of social development, and community construction must also take the digital road. Digital technology improves the performance of information collection, propagation, processing, and display, and enhances security and anti-jamming capabilities. From a technical point of view, after the video intercom is digitized, it solves the two main problems of the network that are difficult to solve by analog systems: long-distance audio and video transmission problems and network multi-channel problems, and can use digital video terminals as a node, it realizes the integration with home alarm, home lighting system and home appliance control system. Integrate a variety of community functions, such as announcements, photo/messages, electronic photo albums, security alarms, access control, smart home, community shopping, community medical and other functions and value-added services.

Nowadays, China's building intercom market is undergoing the process of converting from analog to digital, and from bus to TCP/IP. In residential video intercom projects in new communities, over 70% use TCP/IP transmission based on international standards all digital building video intercom under the agreement. As the TCP/IP all-digital building intercom technology matures, the effect of scale will gradually reduce the cost of digital technology and achieve a wider range of applications.

2. Conform to the convergence trend of the three networks

The development of network communication technology from wired network to wireless network and mobile wireless network, especially the popularization of mobile wireless network from 2.5G GPRS to 3G WCDMA, CDMA and TDSCDMA, as well as the development of 4G, make the information all the time and everywhere.The communication capability is greatly enhanced, providing a network infrastructure for the Internet of Things and ubiquitous computing.

On August 17, 2013, the State Council released the "Broadband China" strategic implementation plan. Broadband households have risen to the national strategic height. On this basis, the technical functions of telecommunications networks, radio and television networks, and the Internet have tended to be consistent, and the business scope has tended to for the same, network interconnection, resource sharing, smart homes should take advantage of this trend and expand the scope of application.

   3. Sensing technology to build community Internet of Things

 Internet of Things technology is the main component of a smart city. Smart chips and sensors will have an unimaginable application space, realize the ubiquitous computing stage of real-time acquisition of information from multiple sources and intelligent control, and enable the development of intelligent environments and peripheral computing. The development of the Internet of Things has fundamentally improved the ability to collect information and will also promote the intelligentization of the human-centered surrounding environment.

4.Integrate community functions to achieve sustainable development

A smart community should be a complete ecosystem, including not only linkage control of alarms, home control, monitoring, elevators, etc., but also access to surrounding environmental information to integrate the discrete functions of the community and realize resource sharing. Bring convenience to users' lives, such as property information, life services, shopping, water and electricity payment, medical services, educational information, housekeeping services, neighborhood committees. In addition, the ideal smart community should pay attention to environmental protection and energy conservation, realize the sustainable use of resources, meet current needs, and at the same time, it must not harm the future generations and achieve the sustainable development goals of the human living environment.
