    What should I pay attention to when purchasing an automatic door opener?

    How to choose a suitable automatic door opener from purchase to installation?(1) Select the professional factory(2) Purchase cost(3) Which automatic swing gate openers to choose,We have highlighted this.(4) When purchasing a door operator, the compatibility of the door operator should be considered.(5) Engineering problems1:Select the professional factory- personal recommendation to cooperate with the factory directly. Cut out the middleman.If you have any questions, you can also communicate with the factory directly ( Email to: sales@s4a-access.com)Any machine will have certain problems after a certain period of use, so when purchasing a machine, first check whether the purchasing unit is a professional sales unit and whether it can provide good after-sales service. At present, most of the automatic door manufacturers of most brands use the regional agent authorization method for distribution, and the agent provides after-sales service for customers, so that the rights and interests of customers are guaranteed. Of course, it is inevitable that some people will be confused, so you can ask the purchaser to provide relevant guarantee certificates or manufacturer authorization letters when purchasing the machine. One more thing to keep in mind: Beware of fakes.(2) Purchase costEveryone hopes to buy a set of gate swing opener with superior performance, reliable quality and moderate price. Now, the price of door operators on the market ranges from a few thousand yuan to tens of thousands of yuan. There are imported and domestic brands, and the difference is very large. Generally speaking, the price of door operators with better performance and quality is naturally higher, because professional manufacturers do not hesitate to use high-quality parts in order to improve the quality of door operators. As the saying goes: you won't lose by shopping around, you can go to a few more factories or companies, learn more about the price and quality of similar door operators, read more relevant information, and then make a budget.(3) Which automatic gate system to choose,the details as below:If there is a large flow of people, hundreds to thousands of people enter and exit every day, and the door opening is large, such as shopping malls, airports and other occasions, it is better to choose a door operator with a strong brand to avoid failure of the door operator during the peak flow of people. , causing great inconvenience to customers and affecting customer impression.Model:ED200 can meet your demand, the holding force can up to 150KG.If the flow of people is not very large, but the door opening requirements are large, such as a car dealership, you should choose a door operator that can withstand a large weight, so as to ensure that the door operator will not run too slowly. It is best that the door operator also has half-opening Function, that is, when there are no cars or large items in and out, and there are few pedestrians, the opening of the door can be...

    How is the access control system linked with the fire alarm system and video surveillance system?

    Linkage between access control system and fire alarm systemIn places with relatively dense traffic, it is difficult to evacuate people in emergencies such as fire alarms and terrorist attacks, especially after the installation of access control systems in these places, this problem is particularly obvious. It has become a major obstacle to people's escape. Therefore, the access control system must have the function of fire-fighting linkage.The signal output by the fire alarm system is usually a passive dry contact signal, and the access control system can be linked with it in two ways.Directly power off the electric lock controlled by the access control systemThe fire protection system can be directly connected to the relay (it should be pointed out that when the relay has no fire alarm signal, the coil should be in a power-off state, so as to prolong the life of the relay) to control the electric lock power supply of the access control system, that is, the relay is normally open. The contact controls the on-off of the 220V power supply. When a fire alarm occurs, the relay will act in time to force the power-off control of the electric lock power supply of the access control system (mains power and backup power supply), so that the designated door can be automatically opened when the system is powered off. . The advantage of this method is that it is easy to use, but the controller has no access to alarm signals and no corresponding records are kept.Access control system logical judgment linkage (indirect linkage)The alarm signal of the fire alarm system is directly communicated with the linkage expansion port of the access control controller. This method can realize input functions including fire alarm signal input, glass breaker alarm signal input, etc., as well as sound and light alarm signal output, forced electric lock. Action output and other functions. In the event of a fire, the access control controller will accept the fire alarm signal transmitted by the fire alarm system in the form of a relay dry contact (the fire protection system actively sends the signal, and the access control system passively receives and executes control), so as to control the designation according to the prefabricated linkage command. The electric lock automatically opens or closes to facilitate the normal evacuation of personnel and achieve the purpose of escape.In order to further emphasize the safety of the channel and prevent someone from deliberately creating false fire signals to automatically open the electric lock and cause escape accidents, the access control system can be set to the multi-channel fire alarm signal input authentication mode, which can be set to receive multi-channel fire alarm signals. A designated door is only opened when an alarm signal occurs. If only a single-channel alarm signal input is detected, no action command will be issued to the electric lock, but the electric lock can still be opened through the normal legal exit proc...

    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...

    What are the advantages and disadvantages of wireless access control?

    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...

    Analysis of the development trend of Network Access Control systems and solutions-3

    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

    Which kind of Magnetic door holder will be better? Wall mounted or the Floor mounted?  S4A teaches you how to choose

    The Magnetic door holder is a hardware accessory used by every household. It can protect the door leaf and prevent the door leaf from being damaged due to strong collisions. The Magnetic door holder can be divided into wall-mounted and floor mounted from the installation method. Many families will be entangled when choosing: which one is better to choose? Today, S4A will help you analyze it.Understanding Magnetic door holderA magnetic door holder, commonly known as a door bumper, is a device that can hold the door leaf when the door leaf is opened. According to the installation form, the Magnetic door stop is divided into the wall-mounted type and floor-mounted type.A small metal plate is attached to the door and is positioned to come in direct contact with the electromagnet. When energized, the electromagnet will hold onto the metal plate to hold the door open. Mag hold-open devices are connected to the fire alarm system or life safety system.The Magnetic door holder is installed behind the door. When the door is opened, the door is stabilized by its magnetism to prevent it from closing automatically when the wind blows. This is especially suitable for the elderly and children at home, effectively preventing the elderly and children from accidentally locking themselves into the house. inside.The difference between wall-mounted and floor mountedThe function of wall mounted and floor mounted is to prevent the door of the house from touching the wall and damaging the wall, but both wall-mounted and ground-mounted have their own advantages and disadvantages.Wall-mounted1. Under normal circumstances, most households use wall-mounted, which is installed on the wall behind the door, which does not take up space and is more securely fixed.In addition, the wall-mounted does not occupy floor space, has a good decorative effect, does not affect the aesthetics of the home, and is more convenient to use.2. Wall mounted has high requirements on the wall surface. Some owners worry that nailing the door stopper to the wall may cause damage to the wall due to excessive tension. In fact, it is normal to have such a worry.If the wall of the house is made of cement and mixed with a lot of sand, this kind of wall is likely to damage the wall if it is sucked by the wall.Ground-mounted The ground-mounted is installed on the ground, it occupies a small floor area, and the sound insulation effect is better. The distance between the door and the wall is not high, and there is no requirement for the wall.2. When it comes to ground-mounted, it is estimated that some owners feel that ground-mounted is too intrusive, and they are easy to trip when they are not paying attention. When cleaning the room, the ground around the floor-mounted is not easy to clean, and it is easy to rust after a long time of use.The Emergency Door Holder is a powerful "weapon" to protect the wall and door leaf. Choosing a suitable door stopper can prolong the service life of the door...
