The traditional video intercom was introduced from western developed countries in the 1990s and has been widely used in various communities. The emergence of visual intercom equipment provides convenience for two-way visual communication between visitors and residents, so as to achieve image transmission and recognition, thereby increasing safety and reliability. However, traditional intercom recognition relies on human eye recognition, and the system The reliability is not strong.

With the advent of Face Recognition Time Attendance technology, the advantages of traditional video intercom systems are gradually being replaced, and many high-end communities are also replacing traditional video intercom systems with Face Recognition Time Attendance Access Control systems, thereby improving community security and convenience
The traditional video intercom we see every day is a part of the common building intercom system. It has been used in my country for nearly 30 years and has been popularized for more than 10 years. It is a relatively common community safety management system. Most of the mainstream building intercom systems generally include two parts, namely, ID card access control, which is the card swiping Access Control System, and the video intercom system, also known as the video doorbell. The working principle of this system is simple. Residents hear the ringtone, just like answering a videophone, and judge whether to open the door through the image and sound signals transmitted by the visual system. Therefore, the security of this system comes from human eye recognition and human ear recognition. .
Face Recognition Time Attendance is a biometric technology for identification based on human facial feature information. It mainly uses a camera to collect images or video streams containing human faces, and automatically detects and tracks human faces in the images, and then performs a series of related analysis and recognition technologies on the detected faces. Once Face Recognition Time Attendance is applied to community management, the security and convenience of the community will be greatly improved. First of all, Face Recognition Time Attendance is an intelligent system based on cloud platform and big data. The basic information of all members of the community is entered into the cloud platform. At the same time, the cloud platform can exchange data with public security and other systems. It has basic control over various groups of people and has the ability to prejudge high-risk groups. Secondly, the Face Recognition Time Attendance system does not require the owner to carry other access control auxiliary equipment, such as access control cards. For community residents, it undoubtedly greatly improves the convenience. At the same time, the recognition efficiency of the Face Recognition Time Attendance system is high, surpassing Face Recognition Time Attendance, voice recognition, and ID card recognition. The Face Recognition Time Attendance efficiency of Shenzhen Yungan IoT can reach the second level. Finally, for community management, the biggest advantage of Face Recognition Time Attendance is safety. It can have timely effects on different groups of people entering the community, such as residents, visitors, salesmen, couriers and even criminals. Once a dangerous person is found, Simultaneously issue warnings to communities, security, police stations, etc.
On the basis of traditional video intercom, combined with Face Recognition Time Attendance, cloud platform, big data and other Internet of Things technologies, it is possible to open the door by swiping your face in the community.
