We have noticed that several customers have recently asked the same question, why did they receive the price it is cheaper? From the pictures, they all look like identical products, but our prices are much higher than those of our peers.Therefore, to solve the customer's doubts, we deliberately ordered back samples from peers for comparison.We take door handles, an everyday item seen everywhere, for instance. I have crafted a detailed  comparison chart for your reference.In today's competitive market, many factories are focused on producing low-priced products to attract customers. While this approach might seem appealing at first glance, it's important to understand that not all products are created equal, even if they appear similar in pictures. At S4A, we prioritize quality, durability, and customer satisfaction, which is why our prices are higher than those of our peers. To clearly understand the value we offer, we have created a detailed comparison table highlighting the differences in material, size, workmanship, thickness, and other key aspects.Understanding the Difference: Quality Over QuantityMaterial Quality: The materials we use are carefully selected for their durability and performance. While many low-priced products use cheaper, less durable materials, our products are made from high-quality components that ensure longevity and reliability.Precision and Workmanship: Our manufacturing process involves meticulous attention to detail and superior craftsmanship. Each product undergoes rigorous quality control checks to meet our high standards, which may not be the case with lower-priced alternatives.Size and Specifications: Our products are designed to meet exact specifications and standards. We ensure that each product is manufactured to precise dimensions, providing consistency and reliability that you can trust.Thickness and Robustness: The thickness of the materials we use is often greater than that of our competitors. This added thickness contributes to the overall strength and durability of the product, making it more resilient to wear and tear.Innovative Design Features: We incorporate innovative design features that enhance the functionality and usability of our products. These features might not be visible in pictures but make a significant difference in performance and user experience.The Comparison TableTo give you a detailed understanding of why our prices are higher, please refer to the table below:Conclusion:While the initial cost of our products may be higher, the long-term benefits and value they provide far outweigh the savings offered by lower-priced alternatives. Investing in quality means fewer replacements, less downtime, and a better overall experience. We believe that our customers deserve the best, and we are committed to delivering products that meet and exceed their expectations.We hope this detailed comparison helps you understand the reasons behind our pricing and the value that we offer...

A magnetic shear lock, also known as an electromagnetic shear lock or maglock, is a security device commonly used in access control systems to secure doors. It consists of two main components: an electromagnet mounted on the door frame and a metal plate attached to the door. When activated, the electromagnet generates a strong magnetic field that holds the metal plate in place, preventing the door from being opened.Here is a detailed description of a magnetic shear lock:Design and Installation: A magnetic shear lock typically features sturdy construction with an electromagnet encased in durable housing. The electromagnet is installed on the door frame, while the metal plate, often made of steel, is fixed to the door. The two components align when the door is closed, allowing the electromagnet to secure the door effectively.Working Principle: When an electric current passes through the electromagnet, it generates a powerful magnetic field. This magnetic field attracts the metal plate, creating a secure bond between the door frame and the door. The magnetic force is strong enough to withstand a significant external force, providing a reliable barrier against unauthorized entry.Control and Activation: Magnetic shear locks are typically controlled by an access control system, which can include keypads, card readers, biometric devices, or centralized control software. When a valid access credential or command is received, the control system activates the magnetic shear lock, allowing the door to be securely locked or unlocked.Advantages of Magnetic Shear Locks:Strength and Security: Magnetic shear locks offer high-strength locking capabilities, providing a robust level of security. The magnetic force between the electromagnet and metal plate is difficult to overcome, making it challenging for unauthorized individuals to force open the door.Fail-Safe Operation: In the event of a power failure, most magnetic shear locks are designed to release automatically, ensuring that occupants can safely exit the premises without being trapped inside. This fail-safe feature enhances safety in emergency situations.Quick Response Time: Magnetic shear locks can be activated and released rapidly, allowing for efficient access control. This is especially beneficial in high-traffic areas or during emergency situations where quick access is crucial.Durability and Low Maintenance: These locks are typically built to withstand heavy use and adverse environmental conditions. With no moving parts, they have a longer lifespan and require minimal maintenance compared to mechanical locks.Versatility: Magnetic shear locks can be used with various door types, including wooden, glass, and metal doors. They are suitable for both interior and exterior applications, offering flexibility in their installation.It's worth noting that while magnetic shear locks provide strong security for access control, they may not be suitable for all applications. Factors such as fire safety regulat...

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
