S4A will accept any reasonable request, and we will take relevant videos for customers to confirm before shipment.

A customer I have been working with for 5 years asked me, "Are you sure this switch Button and base can work together?" I went to the workshop and took a product and fixed it with screws without saying anything. This is S4A's service

If we only look at the price and not the quality, how can we compete with others in price? The materials and thickness are different. #magnetic lock #locks #s4a factory

S4A Produces Access Control and Automatic door operators

How to link the Tuya access control switch to the mobile phone? The problem is very simple. First, the Tuya app must be installed on the mobile phone and then powered on. To solve the customer's problem, we went directly to the warehouse to get a sample and took a video for the customer's reference. This is service, and this is our attitude to solve problems.

In today's increasingly competitive and transparent business landscape, customers often seek varied pricing options for identical products, yet they may not always recognize underlying cost factors. A long-standing client, with whom we've partnered for five years, recently inquired about alternative pricing for a particular product. In response, I provided a comparison of three standard price points for their consideration. There is no good or bad product, only suitability and unsuitability.

Here is one of my valued clients sent an email to me,as below: Hi, i would like to know if this handle is controlled by external impulse release? Brand: S4A Item NO.: iLock-06 S4A replied: The handle of the Tuya fingerprint lock is not controlled by external pulse release. The working principle of the Tuya fingerprint lock involves identity authentication, communication and control, circuit control, and execution, etc., to ensure that only authorized users can open the door lock. Smart door locks use built-in processors to verify the identity of users through password recognition, fingerprint recognition or other biometric technologies. Once the identity is authenticated, the door lock will perform unlocking or locking actions through the internal microprocessor and electronic circuit. In addition, smart door locks also have security protection functions such as anti-theft alarm and fire prevention technology to ensure the safety of users. Although smart door locks may be affected by external factors, such as high-intensity electromagnetic pulse (EMP) devices that exert strong magnetic shocks on the internal circuits of smart locks, this does not directly control the unlocking of the door lock through external pulses. Instead, the internal protection mechanism of the smart door lock is used to deal with this interference and ensure its normal operation and safety.

Technical Evaluation and Assurance of K80 Access Control Power Supply We recently received feedback from one of our esteemed clients regarding the compatibility of our K80 access control power supply with an electric RIM lock. The client expressed concerns about the power supply's ability to adequately power the lock. In response, our team of engineers promptly conducted a thorough diagnostic test, capturing the process in a video for transparency. The test results were conclusive: the electric RIM lock drew an instantaneous power consumption of 58 watts, well within the capabilities of our 5-ampere K80 power supply. Our K80 model is equipped with sophisticated microchip-based protection against overload and overvoltage, ensuring the safety and longevity of connected devices. It is designed to comfortably power 2pcs locks, each with a current draw typical for such devices. However, when the K80 is tasked with powering 4pcs locks simultaneously, it intelligently implements current limitation to maintain stable operation and protect the power supply from excessive loads. This feature is a testament to the unit's advanced design, which prioritizes both performance and safety. We are confident in the performance of our K80 power supply and stand by its ability to meet the power requirements of various access control systems. We appreciate the opportunity to address our client's concerns and are committed to providing reliable, high-quality products that exceed industry standards.

We don't just sell products, we also provide suggestions and solutions. As long as you don't understand something, we can explain the function of this product to you in the simplest way. If the text is unclear, we can explain it through pictures or videos. Today, a customer in cooperation suddenly asked me: Anna, you have produced so many access control units. I used to buy one relay controller only. I found that there is a Dual-relay Standalone Controller with 2 relays on your website. Why should I spend more money to buy this product with 2 relays?  Why is there such a big price difference with 1 more relay? If you have the same question, you are welcome to continue reading. The Dual Relay Standalone Controller supports two relays and has 7 different working mode outputs. Interlocking and anti-passback functions can be realized. Generally speaking, these two functions can only be realized with software, such as ACB-001 002 004 models. 1: Wiegand Reader 2: Standalone for single door 3: Standalone for two doors 4: With an external reader for two doors 5: Two units interlocked for two doors 6: Anti-passback for single door 7: Anti-passback for two doors https://lnkd.in/gtCB8NbZ
