Compared with traditional access control, the emergence of wireless access control is the best interpretation of the definition of wireless, which swept away the tediousness and complexity attached to access control, but the stability and security that followed were greatly reduced. Although wireless technology is constantly breaking through the barriers of line, distance and cost, its further improvement and breakthrough in security will be the killer to completely defeat wired access control and seize the market and users in the future.The traditional access control is to use complex wiring to network the cables of each door point, including power supply and control, and the amount of engineering is very large. However, with the rapid development of access control technology and the widening of applications, more and more industry peers and customers have begun to realize that traditional wired networked access control system solutions may not be suitable for some professional applications, such as inconvenient wiring engineering. , or already renovated residences, or hotel room access control systems with a huge application volume. So wireless access control was proposed in this context.The advantages and disadvantages of wireless access control coexistIt has been more than ten years since wireless access control was proposed, but according to the situation of its market application, it is not optimistic. The reason, Anna Zhang, product manager of S4A industrial co.,limited, believes that at present, manufacturers and users are watching the growth of wireless technology with a wait-and-see attitude. On the one hand, they applaud their breakthroughs in convenience, and many more Users want to try new technology in access control, but on the other hand, they are hesitant to question its stability and security. Although the emergence of wireless access control has reduced the complicated wiring and maintenance projects of wired access control, greatly improved the aesthetics of the access control, and saved the cost of users to a greater extent, it is still technically impossible to do the same as wired access control. To the real-time, smooth, stable and safe effect, the market's acceptance of wireless access control has decreased. Rao Ruqun explained that although there is the protection of encryption technology, wireless transmission is carried out in the air, unlike wired transmission, which is transmitted through lines. If others want to intercept and steal data, they must enter the access control environment and need to pass the line Therefore, it is easy to be intercepted and cracked, and the security cannot be guaranteed.In addition, in the function of avoiding interference, wireless access control is easily interfered by magnetic fields, such as computers, home appliances, etc., which are easy to interfere with the transmission of wireless data. Although manufacturers use frequency hopping technology to avoid interference, they can o...

1. Classification of electric Dropbolt LockElectric Dropbolt Lock can be divided into two-wire, five-wire, eight-wire, etc.; according to different use occasions, such as five-wire, eight-wire and other multi-wire electricDropbolt Lock basically have the function of door magnetic signal detection. In some access control systems, users need to see the real-time opening and closing status of the door on the access control software interface, then they need to choose this electric mortise lock with door magnetic signal detection.2. How to judge the quality of electric Dropbolt Lock?1. When you get the electric dropbolt lock, check whether the surface of the lock body has obvious scratches, and the lock body should have a metallic luster.2. After the power is turned on and the power is turned on for a long time, whether the surface of the lock body is hot, whether the bolt of the electric mortise lock is fully ejected, and whether the bolt springs back forcefully after pressing the bolt.3. Whether the Dropbolt Lock is an ultra-low temperature electric lock, so that the Dropbolt Lock will not get hot during repeated operation, thereby prolonging the service life of the electric Dropbolt Lock.4. Whether the electric Dropbolt Lock has an anti-intrusion circuit design. Some electric Dropbolt Lock on the market are locked by magnetic induction. When the magnetic force artificially disappears or the magnetic force is weakened, the latch springs back to unlock. At the actual installation site, there is a certain gap between the small magnetic plate and the lock body of the electric Dropbolt Lock. Once the magnetic force between the magnetic plate and the lock body is blocked by a small object, the lock body will automatically open because it does not sense the magnetic force. deadbolt. This kind of electric Dropbolt Lock will inevitably have certain security risks. The electric Dropbolt Lock with anti-intrusion circuit protection is locked by sensing the magnetic force of the small magnetic sheet. Once the electric mortise lock is locked, the electric mortise lock can only be opened by receiving the door opening signal or power off. Because of the presence or absence of the magnetic force of the small magnetic sheet, the safety of the Dropbolt Lock is affected.Author: Written by Ms.He from S4A INDUSTRIAL CO., LIMITED

Face recognition is a trend, but also integrationFace recognition is a bright spot and trend in smart access control. As the technology matures, the cost of face recognition equipment continues to drop, even slowly approaching the cost of fingerprint recognition equipment. In some public areas, such as schools, park entrances and exits, for the convenience of fast passage, the verification method of pure face recognition can be adopted. However, in key places, it is recommended to use a hybrid verification method, such as face + card or face + password composite verification. When providing products and design solutions, S4A access control manufacturers will recommend different verification combinations based on the actual use scenarios and purposes of users. In general, smart access control solutions still need to maintain a certain balance in terms of convenience and security.At present, the security of face recognition is already high. It is basically inadvisable to use high-precision printing of photos/videos/3D masks to replace faces and other attack methods. Face recognition equipment can detect living bodies through various technical means, such as binocular cameras, 3D structured light, etc., to effectively identify fake faces.However, it is still necessary to realize that in the overall access control solution, face recognition is only one of the identification and verification methods, and it needs to be better integrated into the traditional access control solution, so that the management server can unify the traditional access control controller and the face recognition device. The data is distributed, and the face-swiping records are completely stored in the entire access control system, forming a complete and unified solution.Of course, if you want to learn more or have a deeper discussion,you can add our whatsapp: 0086 134 1050 0721  (Anna Zhang).Ms or email back to me: sales1@s4a-access.com
