S4A New year holiday's Notificationif you have any questions or require technical support during these days, pls kindly email back to: sales@s4a-access.com Wishing you health, wealth, and happiness in the New Year ahead.Author: Written by Mr.Juan from S4A INDUSTRIAL CO.,LIMITED

With the rapid development of China's economy, people's attention to security issues has prompted the rapid development of China's security industry market. The social security situation caused by the process of economic development is also worrying. The ever-widening gap between the rich and the poor has caused the crime rate in developing countries to rise, and the demand for controlled access systems in society is also increasing.At present, the integration of entrance and exit systems with monitoring, anti-theft alarm, and intercom systems is the general trend, and the boundaries of the four security systems are becoming more and more blurred. The four security systems all rely on computer software integration platforms, including access control and parking lot management systems. The integration of the entrance and exit system and the intercom system also started.If you want to check the demo software,pls contact S4A right now!The access control system and the parking lot system are collectively called the entrance and exit control system. As the name suggests, it is a system that controls the entrance and exit passages. Where to let certain people, refuse certain people, when to sound an alarm, and remember the process of entering and exiting to achieve control Security purpose. It is developed on the basis of traditional door locks. The traditional mechanical door lock is just a simple mechanical device. No matter how reasonable the structural design and how strong the material is, people can always open it by various means. It is very troublesome to manage the keys in the passages where a large number of people enter and exit. If the key is lost or the personnel are replaced, the lock and key must be replaced together.In order to solve these problems, the emergence of electromagnetic locks and electronic code locks has improved people's management of entrances and exits to a certain extent and made the management of channels enter the electronic age. However, with the application of these two electronic locks, Their own defects are gradually exposed. The amount of information stored by the magnetic stripe is small, the contact card and the card reader are worn out, and the failure rate is high. The problem with the magnetic card lock is that the information is easy to copy and the safety factor is low.In recent years, with the development of proximity card technology and biometric technology, the access control system has developed rapidly and has entered a mature period. Induction card access control systems, fingerprint access control systems, iris access control systems, and finger vein recognition access control systems have appeared. , Face recognition access control system, out-of-order keyboard access control system, and other technical systems, have their own advantages in security, convenience, ease of management, etc., and the application fields of access control systems are becoming wider and wider. As the usage...

In non-contact biometric technology, face recognition is the most important module. Since 2019, the application of "face swiping" has been widely used. The epidemic has further promoted development. The future will still be an important direction for AI landing security for a long time. . At present, the traditional face recognition difficulties including face rotation, occlusion, similarity, etc. have been greatly improved, which greatly improves the accuracy of face recognition. With the 2D face, 3D face, and multi-spectral face Represented by multiple modalities, each modal has a different collection and adaptation scenarios, data security levels, and privacy sensitivity, etc. The addition of deep learning of big data enables 3D face recognition algorithms to supplement the defects of 2D projection. The ability to quickly identify people's identities brings certain breakthroughs to the application of two-dimensional face recognition. At the same time, the current living body detection technology is being used as a key technology to improve the security of face recognition, which can effectively resist photo, video, 3D models, prosthetic masks, and other fake fraud, and independently determine the identity of operating users. On the one hand, face applications are mainly for traffic hub scenarios, such as airports and stations, and are mainly used for real-name authentication and key personnel deployment control. On the other hand, it is oriented to city-level applications. Through the docking of the Skynet project, a comprehensive actual combat platform composed of front-end camera deployment and back-end identification platform and big data analysis platform is constructed. In the fields of public security and transportation, the level of facial algorithm technology is leading among AI companies, while traditional companies are mainly led by traditional giants such as Hikvision, S4A, and Dahua. With the rapid development of face recognition technology, many innovative applications such as smart devices, online finance, and face payment have become increasingly common, bringing speed and convenience to everyone's life and work. In addition, in the face of the limitations of Facial recognition access control, gait recognition as a representative body recognition stands out from many technologies due to its difficult to hide, non-contact, and non-invasive characteristics, and has become a "dark horse" in the current biometric recognition field. . Gait recognition recognizes the identity of the target through body shape and walking posture. It is a rather complex behavior feature. Body recognition technology does not require human cooperation and can adapt to more common application scenarios, especially suitable for long-distance identity Recognition. At present, several domestic companies have reached a very high level of recognition accuracy. It is worth mentioning that iris recognition technology is also ...
