With the continuous development of artificial intelligence, in the field of smart home, door locks are another broad audience product after light bulbs, the addition of a large number of manufacturers has rapidly promoted the development speed, and consumers have a wide range of products to choose from. The scale of China's smart home market reached 28.61 billion yuan in 2014, and it is expected to exceed 300 billion yuan in 2020, the market potential is huge. It is expected that with the continuous improvement of Internet technology, if the "new generation" of smart home products can take the lead in this market, it will have an immeasurable effect on the enterprise and the industry.

Smart home is a residential platform, using integrated wiring technology, network communication technology, smart home-system design security technology, automatic control technology, audio and video technology to integrate facilities related to home life to build efficient residential facilities and family schedules the management system of affairs improves home safety, convenience, comfort, and artistry, and realizes an environmentally friendly and energy-saving living environment. Among them, security technology is an indispensable technology in smart home systems.

The security prevention technology in all applications constitutes a home security system, including: access control, emergency help, smoke detection alarm, gas leak alarm, broken glass detection alarm, infrared microwave detection alarm, etc. The access control is the basic application in the entire home security system.

In today's rapid development of digital technology and network technology, access control technology has developed rapidly. The access control system has long surpassed simple doorway and key management, and it has gradually developed into a complete set of access control security management system. It integrates microcomputer automatic identification technology and modern safety management measures, it involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology, it is an effective measure to solve important department entrances and exits to achieve safety management, it is suitable for various confidential department.

The access control system can be divided into the following three categories according to the way of access identification: password identification, card identification, and biometric identification. In recent years, with the development of proximity card technology and biometric technology, the access control system has also developed by leaps and bounds, it has entered a mature period and has its own advantages in security, convenience, and ease of management, the application field is also getting wider and wider. However, the most interesting and most technologically content inside and outside the industry is undoubtedly biometrics. Especially at the 16th Shenzhen Security Expo, major well-known manufacturers have shown the latest research and development and production of biometric access control, which is also an area of in-depth research by major manufacturers in the future, as for the current artificial intelligence collection, the wisdom of security is getting higher and higher.

Today, the access control is in the stage of upgrading, and more new products of the access control system are displayed in front of us, in the future, with the continuous development of artificial intelligence technology, we will combine access control to create safer, more convenient and better smart access control products, and work hard to build a smart city!
