Video intercom Technology
With the development of the national economy and the increasing living standard of the people, some communities have used modern communication technology and automatic control technology to provide efficient and convenient management and service means for the services and managers of the community, provides a safe and comfortable living environment for families. At the same time, the Ministry of Construction of the People's Republic of China has also formulated three levels of Smart Community: the basic standard includes the home anti-theft, fire prevention, gas leak prevention, emergency help and other security systems, three table CC systems, residential management and monitoring centers, and other systems. Closed-circuit television monitoring systems, electronic patrol systems, fire linkage systems, parking lot management systems, home automation systems, and integrated information management systems are added to the standard. In advanced standards, integrated communication network systems and home communication network interfaces are added on the basis of universal standards to meet the needs of the information society.
The Smart Community is expanded and extended in the basic meaning of the smart building. It refers to the four basic elements (structure, system, service, management, and internal association between them) of the residential buildings) to provide an efficient, comfortable, warm, convenient and safe living environment with reasonable investment. In order to adapt to the accelerated development of residential buildings in China, enhance the scientific and technological content of residential buildings, and integrate advanced monitoring, control, and wiring products and equipment at Home and Abroad Based on the Current Situation and Development Trend of smart residential buildings at home and abroad, launched Smart Home Video intercom Technology for residential areas that suit China's national conditions. It not only considers the current construction and long-term development of Smart Community, but also considers the flexibility, security, market adaptability and housing economy of community management.
H.264 is characterized by low bandwidth requirements. At the same quality of restored images, H.264 saves more than 264 of the bit rate than MPEG-4. At the beginning of the design, H.264 considered hierarchical encoding transmission under different network resources. H.264 has strong fault tolerance capabilities. In an unstable network environment, it can produce better quality than MPEG4 video encoding. Of course, the benefits of H.264 are not free, higher compression ratio and good network adaptation performance, but complexity of processing algorithms and higher performance requirements for processors.
Digital visual intercom is currently in a period of accelerated development, both in the market and in technology, and has become an important role of digital families. It has three main elements: video compression, voice processing, and network transmission, so that digital video intercom can be integrated with other family multimedia products. As a result, with the development of technology, the built-in processor is also put forward higher requirements.
