Based on the access control in the smart home security system?
HC Security Network News in the field of intelligent home, the door is the second bulb has a wide audience product, adding a large number of manufacturers promoted the development of fast speed, so that consumers have a wide range of products to choose from.
In the field of smart homes, door locks are another broad audience after the light bulbs. The participation of a large number of manufacturers has drove the development speed very quickly, and also allows consumers to have a wide range of products to choose from. In 2014, China's smart home market reached 28.61 billion yuan, 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, "new generation" smart home products will have an inestimable effect on enterprises and industries if they can take the lead in this market. The position of locks in smart homes cannot be ignored. We can't do every part of smart homes. As long as we grasp the development of them, there is a big "money map."
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 home life related facilities, build efficient residential facilities and family schedule The transaction management system enhances 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 safety precaution 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. Access control is the basic application of the entire home security system.
In the rapid development of digital technology network technology, access control technology has developed rapidly. The access control system has already surpassed the simple doorway and key management, and it has gradually developed into a complete access control security management system. It integrates microcomputer automatic identification technology and modern safety management measures, involving electronic, mechanical, optical, computer technology, communication technology, biotechnology and many other new technologies. It is an effective measure to solve the security management of important departments' entrances and exits. Confidential department.
The access control system can be divided into the following three categories according to the access identification method: password recognition, card recognition, and biometric identification. In recent years, with the development of proximity card technology and biometric technology, the access control system has also undergone a leap-forward development, entering maturity, and each has its own specialties in terms of security, convenience, and manageability. The access control system The field of application is also growing. However, the most interesting and technologically advanced inside and outside the industry is biometric identification.
Access control biometrics: extremely low cost and high security
Since the human body features the inherent non-replicable uniqueness of the human body, this biometric key cannot be copied, stolen or forgotten, and biometric identification is more secure, confidential and convenient than traditional identification methods.
Biometrics can be broadly classified into two types: physical feature recognition and behavioral feature recognition. Physical characteristics include: fingerprint recognition, vein recognition, palm geometry recognition, retina recognition, iris recognition, facial recognition, DNA recognition; behavioral characteristics include: sound and signature recognition, gait recognition. The biometric system samples the biometric features, extracts their unique features into digital codes, and further groups the codes into feature templates. When people interact with the identification system for identity authentication, the recognition system compares the feature with the feature template in the database to determine whether the two match, thereby determining whether to accept or reject the request identifier.
