Video intercom integration smart home function has become an industry trend

Introduction: Strictly speaking, smart home control and video intercom are two different functions, but today, as technology becomes more mature and market demands increase, they are already integrated into a complete home intelligence system. The combination of visual intercom and smart home has become the development trend of the industry. Strictly speaking, smart home control and video intercom are two different functions, but today, as technology has become more mature and market demand has exploded, they have been integrated into one complete home intelligence system. The combination of visual intercom and smart home has become the development trend of the industry.

Smart home and video intercom are two completely different functions. The smart home focuses on the intelligent control of all kinds of electrical equipment inside the house, while the video intercom is a community intelligent security function based on video, audio and control functions. Now, with the rapid development of smart home and video intercom technology, the combination of video intercom and smart home has become an inevitable trend. The residential intelligent control terminal with embedded video intercom function has become a perfect solution for smart home systems. In particular, with the digitization of video intercom technology and the networking of TCP/IP, the video intercom function and the smart home function have been seamlessly integrated, that is, the two technologies have achieved unobstructed integration. For example, smart homes can realize intelligent control of residential interiors, such as lighting control, electrical control, curtain control, security alarm, background music, audio and video sharing, and other smart home functions.

The trend of intelligent development is a high degree of system integration, which is the use of intelligent terminal equipment to achieve security and residential intelligent control functions. If each control function is implemented by an independent subsystem, then this will increase the cost of a lot of hardware and software costs, and it will also fail to realize the real information exchange from urban intelligence to community intelligence to residential intelligence. . The future trend of smart development is the concept of smart city intelligence, community intelligence, and family intelligence, which will truly realize seamless connectivity and information exchange, and finally realize the Internet of Things.

Intercom / smart home system control signal transmission technology What are the smart home systems, the technology continues to innovate throughout. Among them, control signal transmission is the foundation and core of smart home technology. At present, the smart home system signal transmission is still mainly based on the bus system, or there is auxiliary wireless technology. In general, the wired control system of the bus system mainly pursues the stability of the system and the powerful function, as well as the compatibility of the system and other subsystems of the residential community and information exchange and mutual control; while the wireless control, mainly focuses on the pursuit of free wiring, As well as mobile control, especially how to intelligently renovate the renovated users, this is the most important application of wireless systems. Therefore, in the future, the control signal transmission technology of smart homes is still the simultaneous development of two technologies, bus and wireless, and promote each other. In the same system, there are both wired control technology and wireless control technology, which are complementary and complementary. At present, most smart home control systems have both wired technology and wireless technology, because all wired smart home technologies will have wireless remote control functions, and this wireless remote control function is either using infrared remote control or RF remote control. Or through WIFI, Bluetooth and other ways to achieve; and wireless smart home control system is also based on the original wiring, to achieve a limited area of ​​the wiring, wireless control.

At present, the bus technologies of smart homes mainly include bus technologies such as EIB, LONWORKS, CANBUS, APBUS, and CEBUS, and wireless technologies are mainly based on RF technologies such as RF, wireless infrared, ZIGBEE, and 2.4G. In the future, the development of smart home control technology is expected to use bus technology in areas where wired control is a must, while wireless technologies are used in areas that require no wiring, but also pursue mobility and convenience. Through the organic combination of wired and wireless technologies, it not only reduces the amount of wired engineering wiring work, but also avoids the drawbacks of limited coverage of wireless technology signals, signals susceptible to interference, signal instability, so that the overall operation of the system is more stable, The operation is more convenient and the wiring volume is smaller.

For the video intercom technology, the black and white video intercom has been fully integrated into the color video intercom. From a purely technical point of view, it has been developed from the previous analog audio and video and bus control technologies to TCP/IP. The technology-based digital video intercom makes the video intercom system wiring easier, and the signal transmission distance is no longer an obstacle. Realizing video intercom remote video control and monitoring has become a trend in the future. Of course, video intercom integration smart home is an inevitable trend in the development of two industries or two technologies. Video intercom needs smart home functions, and smart homes need visual intercom to promote the industry to scale development.

Intercom/Smart Home System Application Status At present, domestic smart home systems or products, the main function is to light, electrical, curtain control, smart home function is still relatively single, smart home system system manufacturers can integrate more features is not a lot . The “thinker” smart home system produced by a smart home system manufacturer in Shanghai adopts the international leading smart home design concept. The system consists of basic home communications (wired and telephone signal distribution, broadband Internet access) to lighting, electrical appliances, and curtains. Background music, video sharing, security alarms and other functions are truly realized by using a remote controller and a key to control the entire home intelligent system.

Now, there are also some smart home manufacturers joint video intercom manufacturers to develop and produce protocol conversion modules that can communicate with each other, and realize smart home functions in video intercom. At present, mainstream video intercom manufacturers such as Di Nike, GUAN Lin, Zhenwei, Anjubao, TCL, Legrand and other products can basically realize the products of smart home manufacturers with mainstream bus technologies and wireless technologies. Communication. Objectively speaking, current products have yet to be improved in terms of control stability, multi-functional combination, and refinement, which requires a long process of technological deepening and function refinement. For video intercom, integrating smart home functions is also a need for market development. Because for the real estate business, integration of video intercom and smart home functions will serve as a new selling point. If the two systems are installed independently, they need a video intercom and a smart home platform, which is not conducive to real estate. The decline in development costs is inconvenient for users. Therefore, integrating the two systems into one system and sharing one intelligent terminal as the user operation control interface under the same system platform is the most ideal solution choice.

Intercom/smart home systems currently have difficulties in practical applications. For visual intercom products with smart home functions, objectively speaking, applications are not too many. From the perspective of the real estate agent, the main reason is cost considerations. The cost of video intercom products based on TCP/IP technology is much higher than that of ordinary video intercom products. If smart home functions are integrated, the cost of developers will increase significantly, exceeding the capacity of real estate developers. . Therefore, the current high-end video intercom products are mainly used in some very high-end villa projects or high-end residential projects. However, with the combination of visual intercom and smart home features, everyone also sees the combination of the two is an inevitable trend. Therefore, with the deepening of the concept of integration of new smart home and video intercom, and the increase of application cases, it may be only a matter of time before it is widely used.

From the technical point of view, the application of the intercom/smart home system is mainly to consider the stability of the product, and the other is to design the intercom/smart home function from the engineering point of view, to see whether the product is convenient for installation and maintenance. However, the current video intercom products with smart home functions are mainly based on the video intercom function. In fact, it is still focused on the intercom security function of residential buildings, and the smart home function within the home is still relatively simple. To achieve a full range of smart home functions, perhaps to replace the original installed system, this is also determined by the cost factor, but these problems will be gradually resolved with the maturity of technology and the market, and the cost reduction.

The future development of intercom and smart home systems The author believes that the combination of visual intercom and smart home is a technological development and market demand, both in terms of market and technology. Of course, the market will have more and more powerful personalized products that can meet the needs of users at all levels or higher levels. Therefore, the smart home industry will develop toward two mainstream markets in the future. The first is the products that are suitable for common community-based integrated video intercom and basic smart home functions; and the other direction is the upgrade of high-end users. Smart home products. From a market perspective, if smart home products for community use can be widely used, the smart home market will be promoted to scale, while for smart home products with single-family products, due to relatively expensive product prices, the current applications are mainly concentrated in the wealthy category. crowd. If it is only to develop single-family smart home products to develop the smart home industry, smart home products may be positioned as high-end consumer products for a long period of time, rather than popular products.

Therefore, the integration of video intercom and smart home products is an inevitable trend in the development of intercom and smart home systems, which will not only facilitate the development of smart home and video intercom industries, but also accelerate the technical upgrading of the two industries.
