    Analysis of the development trend of Network Access Control systems and solutions-2

    A balance of safety and convenienceThe advantages of smart access control are obvious, such as increasing convenience and realizing the diversification of verification methods: in real life, face recognition, mobile phone replacement of access control cards, etc. have brought great convenience to users; at the same time, the new development of intelligent access control has also Let the security have a new technical guarantee. Taking face recognition as an example, it can effectively identify the identity and prevent the occurrence of card punching and card theft. But on the other hand, compared with traditional access control, there are also new security risks in the upgrade of human-computer interaction experience, such as face recognition data being cracked, face similarity and false release, etc.Therefore, in the deployment of Network Access Control system solutions, manufacturers must grasp the balance between convenience and security. Once the balance is out of balance, there will be security risks.Take the NFC access control card as an example. In practical applications, NFC access control cards are divided into several types. If the user's awareness of safety precautions is insufficient and the user only pursues convenience, it is easy to use simple cards that can be copied by mobile phones in areas with relatively low security precautions, such as communities and underground garages. create a safety hazard. In fact, in these scenarios, virtual cards can be used, and the access control system issues virtual card numbers through exclusive channels. The operation from the cloud to the local has a very complete security mechanism, which will not be easily copied and can increase the safety factor. If the mobile phone is lost, the virtual card can also be frozen quickly, and the cloud authorization certificate is constantly refreshed, so that the validity of the virtual card number can be grasped in real time.At present, many domestic door access control solutions consider convenience, and the awareness of security precautions needs to be strengthened. In practical applications, scenarios with lower security levels in ordinary commercial buildings can be more convenient for users; however, key industries, such as airports, electronic manufacturing plants, nuclear power plants and other application places, need to use state-secret CPU cards, Mifare Access control solutions with higher security standards and encryption technology such as the DESFire EV1 card.S4A has always regarded the realization of product safety as the highest priority and has a very complete safety process. In the product development stage, S4A has already regarded data security as an important consideration, and needs to go through the security review process; after the development is completed, it needs to pass a strict penetration test, inviting data security companies to simulate hackers from the network level, software level, and operating system level. , or e...

    Analysis of the development trend of Network Access Control systems and solutions-1

    Driven by technologies such as artificial intelligence and the Internet of Things, the technological innovation of Network Access Control system has entered a new stage, which is both an opportunity and a challenge for the application of the access control industry. The development of the Internet of Things, the increasing maturity of artificial intelligence, the implementation of face recognition technology and the continuous decline of equipment manufacturing costs, coupled with the high popularity of biometrics, make the promotion of smart access control more favorable. However, there is still room for improvement in its security and stability. It can be said that ensuring the security of Network Access Control Panel is a long-term and continuous challenge. It is not only intelligent, convenient, but also safe and stable. This is the development ambition of access control enterprises and the development direction of the industry. Achieving the security and convenience of the access control system is the choice for enterprises not to forget their original intentions and to live up to the futureForeword: The advancement of artificial intelligence and mobile Internet technology has stimulated a new round of development of the entire access control industry, bringing new players to the industry and new ideas for the development of the entire traditional access control industry.Any product that changes people's daily behavior is inseparable from the support of several technological innovations. In this world where information technology is rapidly updated and potential threats are constantly changing, smart access control can be said to be a product of the times - the Internet of Everything makes the access control system an existence beyond security and has a wider range of application scenarios; Self-learning and self-thinking; the biometric function allows users to free their hands and become a pass.In addition, in terms of technology, artificial intelligence technology, Internet of Things and mobile Internet applications (such as the widespread use of mobile phone Bluetooth, NFC and other technologies) have brought new opportunities for the development of the access control industry. From a policy perspective, the national and local standards for the access control industry issued in 2018, such as the national standard GB/T 37078-2018 "Technical Requirements for Entry and Exit Control Systems", have promoted the development of intelligent access control. So how should smart access control in the new era develop to surpass security, meet future needs, and present more value?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.comAuthor: Written by Ms.Anna Zhang from S4A INDUSTRIAL CO., LIMITED

    How to distinguish and choose dropbolt lock?

    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
