In recent years, with the construction of smart cities and the improvement of social living standards, people's requirements for the community environment are no longer limited to living area, transportation and other hardware facilities. They are more concerned about the safety and comfort of the living environment. As an important device in the households, building intercom has played a huge role in community informatization, improving the quality of living, and improving the quality of property services. The combination of building intercom and the application in smart communities has become the development trend of industry. LEELEN also launched Video Doorbell Black M57 and 10.1" Large Touch Screen Video Indoor Station V37 for this trend. Smart community services make full use of advanced technologies such as the Internet of Things, cloud computing, and 4G to put forward the idea of community-integrated services and owner integrated services. A community management platform that integrates cloud access control, cloud intercom, community shopping, community information, video surveillance, and home smart control has been created to realize the intelligent and convenient management of the community.

Most video intercom suppliers in the current market are extending, trying, and exploring the product lines needed to build smart communities. However, from traditional building intercom to smart communities based on the Internet of Things, except visual intercom will also integrate more terminal equipment (elevator control system, intercom system, access control system, cloud access gate, robot elevator, etc.) and integrate multi-modal solutions, like the Ultra Thin Digital Indoor Intercom Station V31S from LEELEN. As an important information transmission equipment for communities and families, building intercom manufacturers use the intercom system as the entrance and extend to various product lines such as property management, community security, smart parking, smart home, and community business districts through smart community platforms, providing overall solutions for communities and families smart. The smart community platform has expanded functions that are more powerful and diversified value-added services to better contribute to the construction of smart communities and provide smart services for owners.
