At present, there are four main types of fingerprint image acquisition technologies used in the market: optical scanning equipment, temperature-sensitive fingerprint sensor, semiconductor fingerprint sensor and ultrasonic fingerprint scanning.

　　I. Optical identification technology

　　Fingerprint collection by optical technology is the oldest and most widely used technology. Put a finger on an optical lens, and project it on a charge coupled device (CCD) with a prism under the illumination of a built-in light source, so as to form a digital multi-gray fingerprint image with ridges (lines with a certain width and direction in the fingerprint image) in black and valleys (concave parts between lines) in white, which can be processed by a fingerprint device algorithm.

　　Optical fingerprint collection technology has obvious advantages: it has been tested for a long time, adapted to the variation of temperature to a certain extent, and can reach a higher resolution of 500DPI, and most importantly, it is low in price. There are also obvious disadvantages: because the optical path is required to be long enough, the size is required to be large enough, and excessively dry and greasy fingers will also make the effect of optical fingerprint products worse.

　　The limitation of optical fingerprint sensing lies in the potential fingerprint (the potential fingerprint is left after the finger is pressed on the platen), which will not only reduce the quality of fingerprint image, but also lead to the overlap of two fingerprints in serious cases, which obviously cannot meet the needs of practical application. In addition, the coating on the platen and the CCD array will wear out over time, which may lead to the degradation of the quality of the collected fingerprint image. However, it has some disadvantages, such as unable to identify living fingerprints and poor applicability to wet and dry fingers.

　　Optical fingerprint identification system can only scan the surface of finger skin or the dead skin layer, but it can’t penetrate into the dermis layer. In this case, the cleanliness of the finger surface directly affects the recognition effect. If there is a lot of dust on the user’s finger, there may be a recognition error. Moreover, if people make a fingerprint hand model according to their fingers, it may also pass through the recognition system, which is not very safe and stable for users to use.

　　Second, the temperature difference induction identification technology

　　The temperature difference induction recognition technology is based on the principle of temperature induction. Each pixel is equivalent to a miniaturized charge sensor, which is used to sense the temperature difference at a certain point between the finger and the chip image area and generate an electrical signal representing the image information.

　　Its advantage is that the fingerprint image can be obtained within 0.1s, and the sensor has the smallest volume and area, that is, the sliding fingerprint reader usually uses this technology at present. Disadvantages: Limited by temperature, the finger and the chip will be at the same temperature after a long time.

　　Three, semiconductor silicon induction technology (capacitive identification technology)

　　In the late 1990s, the technology based on the capacitance effect of semiconductor silicon became mature. The silicon sensor becomes one plate of the capacitor, and the finger is the other plate. By using the capacitance difference between the ridges and valleys of the fingerprint line relative to the smooth silicon sensor, an 8-8bit gray image is formed.

　　The capacitance sensor sends out an electronic signal, which will pass through the surface of the finger and the dead skin layer, and directly reach the living layer (dermis layer) of the finger skin, so as to directly read the fingerprint pattern. Because it goes deep into the dermis, the sensor can capture more real data, and it is not easily affected by the dust on the finger surface, which improves the identification accuracy and effectively prevents identification errors. Semiconductor fingerprint sensor includes semiconductor pressure sensor, semiconductor temperature sensor, etc. Among them, semiconductor capacitive fingerprint sensor is the most widely used.

　　The semiconductor capacitance sensor judges which position is the ridge and which position is the valley according to the different capacitance values formed by the ridges and valleys of the fingerprint and the semiconductor capacitance sensing particles. Its working process is to pre-charge the capacitive sensing particles on each pixel to a certain reference voltage.

　　When the finger touches the fingerprint of semiconductor capacitor, because the ridge is convex and the valley is concave, different capacitance values will be formed at the ridge and valley according to the relationship between capacitance value and distance. And then discharge by using a discharge current. Because the capacitance values corresponding to ridges and valleys are different, the discharge speed is also different.

　　The pixel under the ridge (high capacitance) discharges slowly, while the pixel under the valley (low capacitance) discharges quickly. According to the different discharge rates, the positions of ridges and valleys can be detected, thus forming fingerprint image data.

　　Different from optical devices which mostly use manual adjustment to improve the image quality, capacitive sensors use automatic control technology to adjust the sensitivity of fingerprint image pixels and local range of fingerprints, and combine feedback information to generate high-quality images in different environments. Due to the ability of local adjustment, even images with poor contrast (such as areas where fingers are pressed lightly) can be effectively detected, and the sensitivity of these pixels can be improved at the moment of capture to generate high-quality fingerprint images.

　　Semiconductor capacitive fingerprint sensor has the advantages of good image quality, generally no distortion, small size and easy integration in various devices. The electronic signal will pass through the surface of the finger and the dead skin layer, reach the living layer (dermis layer) of the finger skin, and directly read the fingerprint pattern, thus greatly improving the security of the system.

　　The most important advantage of semiconductor silicon sensing technology is that it can achieve living fingerprint recognition. Better image quality than optical technology can also be obtained on a smaller surface, and the resolution of 200-300 lines can be obtained on a surface of 1cm×1.5cm (smaller surface also leads to cost reduction and can be integrated into smaller equipment). Because of its small size, low cost, high imaging accuracy and low power consumption, it is very suitable for security and high-end consumer electronic products, and is called the second generation fingerprint identification technology after optics.

　　Fourth, ultrasonic identification technology

　　Ultrasonic fingerprint collection is a new technology, and its principle is that ultrasonic wave has the ability to penetrate materials, and echoes with different sizes are generated with different materials (when ultrasonic waves reach the surfaces of different materials, they are absorbed, penetrated and reflected to different degrees). Therefore, the location of fingerprint ridges and valleys can be distinguished by the difference of impedance between skin and air to sound waves.

　　The ultrasonic frequency used in ultrasonic technology is 1×104Hz-1×109Hz, and the energy is controlled to the extent that it is harmless to human body (the same as the intensity of medical diagnosis). Ultrasonic technology products can achieve the best accuracy, which requires less cleanliness of fingers and planes, but its acquisition time will be significantly longer than the above two types of products, and it is expensive, and it can not achieve living fingerprint recognition, so it is rarely used at present.

　　Micro-optical fingerprint identification technology

　　At present, both the mainstream-capacitive fingerprint sensor and the emerging-ultrasonic fingerprint sensor need additional fingerprint sensors, but the former needs to open holes on the screen and the latter can be hidden under the screen.

　　In 2017, Apple and Huiding Technology introduced fingerprint identification technology based on micro-optical sensing technology, which skillfully integrates the display screen and fingerprint sensor, and supports fingerprint identification in multiple places on the whole screen.

　　The working principle of fingerprint identification sensor "begins" with optical type, "fills" with capacitive type, and "continues" with ultrasonic type and micro-optical type. Turn a circle, and now back to the path of optical sensing, the difference is that today’s micro-optical sensing technology is advanced enough to cause a full "face" innovation of smart phones. What is the principle of micro optical fingerprint sensor? Huiding Technology is different from the technology adopted by Apple. Huiding Technology has not disclosed the details yet, but we can learn about the MicroLED technology adopted by Apple.

　　Before 2012, MicroLED technology was still in the laboratory research and development stage. With Apple’s acquisition of LuxVue, which owns many patented technologies of MicroLED in May 2014, the market’s attention to this technology has reached an unprecedented height. MicroLED technology, namely LED miniaturization and matrix technology. It refers to a high-density micro-sized LED array integrated on a chip. Each pixel of the display screen can be addressed and individually driven to light, which reduces the pixel distance from millimeter to micron.

　　MicroLED display is to thin, miniaturize and array the LED structure design, and its size is only about 1~10μm, and then transfer the micro-LEDs to the circuit substrate in batches, which can be a hard and soft transparent and opaque substrate; Then the physical deposition process is used to complete the protective layer and the upper electrode, and the upper substrate can be packaged to complete the MicroLED display with simple structure.

　　According to Apple’s US Patent No.9570002 "Interactive Display Panel with Integrated Infrared Diodes" published by the US Patent and Trademark Office on February 14th, 2017, the touch display screen with MicroLED sensing technology and how to realize the fingerprint identification technology function are displayed.

　　Specifically, a single infrared emitting tube is connected with a sensing diode as a driver, and a selection circuit is used to create a sub-pixel circuit. Because of their small size, these infrared diodes can be embedded in the display substrate with RGB LED, or installed on a microchip and then integrated into the substrate.

　　During the fingerprint identification operation, a certain area or a few lines of the screen integrated with interactive pixels (so-called "interactive pixels", which can integrate red, green, blue, infrared light emitting diodes, infrared detectors and other color arrays on the panel with very high resolution) can scan the fingerprint information of the user.

　　When the distance reaches enough to be sensed, a bitmap will be generated and the approximate positioning data will be notified to the system. In some cases, bitmaps include incident light intensity information, allowing deep analysis of objects and their surfaces. For example, by checking the dark points and bright points of the bitmap, the sample system can detect the corresponding ridges and wrinkles in the user’s fingerprint. So as to realize the function of fingerprint identification.

　　Fingerprint identification technology is the mainstream technology of biometrics and identity authentication, and it has been widely used in all walks of life. At present, devices with fingerprint function must have a physical key for you to scan a fingerprint, but with the development of touch and display chips, it is highly integrated, and the future development trend is that we can identify fingerprints on the screen at any position. Embedded fingerprint identification appears at the core, so any restrictions do not affect the industrial design of equipment manufacturers. With the integration of fingerprint identification and touch display technology becoming more and more mature, it will be more and more widely used, such as fast payment, identification, personalized preference customization, etc., and it is likely that passwords will be replaced by fingerprint identification technology.

　　How to buy a smart home lock cylinder, and where can I change it?

　　Every year, many people will be killed by thieves before or after the year. At this time, everyone will choose to change the home lock core of the host, so that they will not be afraid of thieves in their later lives. Now the lock core is very scientific and technological, so do you know how to buy smart home lock core, and what is the price?

　　After reading the above article, we know that to choose a lock core, we must choose an intelligent lock core with good quality, so that our life will be guaranteed in the future. A good lock core is not a comfort in our hearts. Don’t care too much about the price. Quality is important, and good quality can guarantee our personal safety.

　　The traditional mechanical door lock can only be unlocked by the key, but it is inevitable that we will forget to bring the key in our life, which will lead to the failure to open the door normally. Fingerprint locks appearing on the market now are also liked by many people, and they have various brands, which can be said to be various and complete in products. However, our most common fingerprint locks are samsung fingerprint lock and Philips. These two brands of fingerprint locks have been widely used in many families, but some consumers are confused when choosing. So, which is better than Philips smart lock and Samsung smart lock?

　　Which is better than Philips smart lock and Samsung smart lock?

　　Everyone is familiar with the brand Samsung. Samsung mobile phones and notebooks have been very famous in China for a long time, so samsung fingerprint lock is still quite popular in China. Philips is also a world-famous brand. The highlights of its fingerprint lock products are high appearance value, attention to detail and good texture. Generally speaking, these two fingerprint locks are relatively high-end fingerprint locks.

　　Samsung and Philips fingerprint locks are now also using semiconductor fingerprint identification technology. The password setting is very simple, which can be completed according to the steps in the manual. The door will be opened with a gentle touch of a finger, and the unlocking by swiping a card and unlocking by a mechanical key are all convenient for the elderly and children.

　　Samsung began to develop smart locks in 1999, and it has a history of 21 years, and its development in technology research and development, lock safety, product quality and other aspects has been relatively perfect.

　　Philips also licenses the brand to domestic companies, which is a subsidiary of Kaidishi. Generally speaking, Kaidishi’s products are similar to Philips, with the same functional configuration.

　　In a word, Samsung and Philips fingerprint lock are both international brands, and the biggest difference between them is in terms of design and price. samsung fingerprint lock, recognized by users, is the representative of Yan value, and the price is also high. Of course, everyone has different opinions.

　　I. samsung fingerprint lock

　　Samsung brand is no stranger to everyone. Many friends are using Samsung brand electronic products, such as mobile phones, televisions and air conditioners. As a world-renowned comprehensive group enterprise, Samsung mainly develops some intelligent products. As the best product of Samsung, the fingerprint lock has been improved in all aspects in manufacturing technology and appearance design, which is also the main reason why samsung fingerprint lock is popular.

　　Second, Philips fingerprint lock

　　Philips fingerprint lock has a history of many years, and it has been continuously improved and innovated in the development process, and many new products have been introduced, which has brought great convenience and safety to people’s lives. However, Xiao Bian believes that Philips fingerprint lock has some shortcomings, that is, the after-sales service is not very timely. In any case, when you buy a fingerprint lock, you must understand it according to your own needs and economic situation.

　　Which is better, Philips smart lock or Cadiz smart lock?

　　At first, "Philips" itself did not produce smart locks, but leased its own brand to "Koenig" (Shenzhen Koenig Intelligent Technology Co., Ltd.) in 2017, with a lease term of 5 years.

　　Since then, "Konis" has become the only authorized partner of "Philips" in the field of smart locks, and has the right to use Philips’ trademark.

　　After a lapse of one year, Kaidishi, the first brother of smart locks in China, took control of Konis, and since then, he has been fully responsible for the domestic operation of Philips smart locks. Based on Kaidishi’s profound knowledge and Philips’ brand empowerment, their respective advantages can be described as incisively and vividly displayed.

　　From the strategic layout of the market, Kaidishi mainly focuses on the low-end market, and "Philips" smart lock can be regarded as another advanced production line for Kaidishi to target high-end imported brands such as Samsung and Gederman, and it is more perfect than many imported brands in after-sales service.

　　Then, the question is, what is the difference between Philips and Cadiz smart locks? Let’s start with the representative "π", "DDL603E" and "7100" in Philips "hand-held" smart locks.

　　These hand-held semi-automatic smart locks are self-contained with the style of "Kaidishi F1", which still continues Kaidishi’s excellent base of "insisting on adopting Swedish FPC semiconductor in all departments", and all of them are designed with double bearings and free handles. The smoothness, durability and stability of unlocking are relatively guaranteed, which is worthy of recognition. Let’s analyze the differences one by one:

　　Philips DDL603E VS Cadiz F1

　　The difference is that "Philips DDL603E" has added "smile indicator" and "anti-coercion alarm". However, the price difference is nearly double … What do you think, little friend?

　　Philips π/7100 VS Cadiz F1

　　There is little difference between the two actual experiences, which castrates the WIFI networking function. The processor is "M3", and the recognition speed is slightly inferior to that of "Philips DDL603e" (M4 processor). However, based on the excellent performance of Swedish FPC semiconductor, the experience will not be bad, at least it can crush many models on the market.

　　The power supply system can put 8 dry batteries, and the endurance is enhanced.

　　In terms of intelligent security, "7100" has the function of "leaving home to protect".

　　This model is very similar to "Kaidishi F1" in panel material, design, function, size and other details, almost a clone version, and even feels similar.

　　In addition to the above details, the remaining difference is the external process.

　　The handle of "7100" has a strong sense of design, the panel is made of zinc alloy with higher strength, and the surface is brushed, which is more textured and not easy to leave fingerprints.

　　The fingerprint identification area is designed above the panel. This design idea is very strange and not very convenient.

　　The surface technology of "π" is mirror bright treatment, which is similar to that of "Kaidishi F1", with some minor changes in shape, which looks more exquisite, but its performance is still slightly inferior to that of "F1".

　　From the price point of view, this round of "Kaidishi F1" is still superior to good quality and low price, while the advantage of "Philips π, 7100" is that its face value is slightly higher.

　　When Philips is in a big promotion, the price is also relatively strong, and the Yan value party can take a wave ~

　　In a word, there are differences between Philips and Cadiz in product design. The grade of Philips is slightly higher than Cadiz, but the internal situation is not much different. After the brand authorization expires, whether Philips will operate on its own or continue to renew its contract is unknown for the time being. Buying Philips smart locks at this time period is essentially the same as buying Kaidishi smart locks, both of which are produced by one company. Kaidishi’s smart lock is not bad in both industrial design and practicality. Kaidishi mainly makes mid-range smart locks, and the Philips brand promoted by Kaidishi makes high-end smart locks, targeting Samsung and Geithmann.

　　Which Philips smart lock is better?

　　1. Philips Smart Lock Alpha.

Anti-electromagnetic interference design, front and rear panels operate independently to prevent electromagnetic attack to kill the machine.

　　4. Philips Alpha (the best-selling flagship model)

　　"Alpha" is a very classic push-pull smart lock of Philips. Compared with the previously mentioned hand-held smart lock, the process of opening and closing the door is simpler.

　　With the accurate and fast recognition experience brought by "Swedish FPC Semiconductor", the whole process of unlocking and automatically locking the door can be completed very coherently, and every time the door is opened, it is as smooth as pushing the door in.

　　Fake ferrule design, the mechanical lock hole is located at the bottom of the lock body, which makes the whole panel look more concise, and with streamlined modeling, the appearance is very simple and neat.

　　There are many ways to unlock the lock, including fingerprint, password, temporary password, card, key and Bluetooth. At the same time, it supports double combination verification mode, which is highly secure.

　　5. Philips DDL702E

　　"DDL702E" is the flagship fully automatic smart lock launched by Philips in 2020. It is very rare that it became the single product sales crown on the day of 618 with "hard core quality" rather than "low price".

　　Compared with "Alpha", it has been improved in almost all directions. For example, with the addition of WIFI networking function, remote intelligent control can be carried out, which is more convenient.

　　Fingerprint identification is faster and more accurate, thanks to the hard-core configuration of "Swedish FPC semiconductor +M4 processor".

　　The CPU card also adopts a new generation of dynamic encryption technology, which is copy-proof and safer.

　　The outdoor three-dimensional integrated handle design with one grip and quick opening endows the high-strength zinc alloy panel with wire drawing technology, and its appearance is very simple and durable.

　　How about Philips’ smart lock?

　　Philips is a world-famous brand and a fortune 500 enterprise, and it has done very well in the fields of sensors, smart chips, personal care, home appliance systems, medical devices, smart cities and so on. Around 2017, Philips entered the field of smart locks, and in December 2017, it launched three smart locks with high quality and high value, and applied NB-IoT technology to realize the interconnection of living equipment and improve the safety and convenience of home.

　　In 2018, Koenigs, a subsidiary of Shenzhen Kaidishi, reached a five-year cooperation agreement with Philips, and Koenigs operated the business of Philips Smart Lock in China. In the early years, Kaidishi had the aura of German brand and competed with many big brands, but the decision-makers chose the wrong marketing method and used price war to expand the market, but lost the high-end market. Kaidishi found Philips and signed a brand licensing agreement.

　　The brand-new fully-automatic push-pull smart lock DDL702E launched by Philips has captured the hearts of many consumers with the functions of Wi-Fi direct connection, simple and fashionable appearance, remote real-time monitoring and so on, and achieved excellent results in 2020, with sales exceeding 10 million all day, single product sales of smart locks ranking first and new product popularity ranking first; In practical use: high-end charming appearance, innovative design, the panel, fingerprint sensor and handle are designed as one, so that it can be opened at once, and the process of unlocking is completely unknown. The biggest advantage of this design is that when you need to escape quickly in an emergency, you can open the door instantly without delay. WIFI direct connection does not need to purchase a gateway, supports multiple unlocking modes and double authentication modes, and the escape sensor is designed to protect safety in times of crisis; There is also a one-button protection and anti-pick alarm function.

　　How much do you know about the five alarm functions of Philips Smart Lock?

　　In the era of intelligence, people’s life can be said to be intelligent everywhere. Of course, there are various intelligent and effective alarm methods, such as high temperature automatic alarm and gas automatic alarm.

　　However, as an entry-level security product, whether it is a traditional lock or a smart lock, the most basic mission of doors is to protect people’s families and lives. Philips smart lock also has multiple alarm functions, has strong security strength, and gives you a stable sense of security!

　　Abnormal alarm of lock tongue

　　In the daily use of Philips smart lock, when the locking bolt is abnormal due to the failure of opening and closing the lock, the smart lock will continuously sound an alarm.

　　For example, a Philips smart lock equipped with a fully automatic lock body will automatically pop up when the lock is closed. Once the lock fails and the lock tongue is abnormal, the smart lock will give an alarm sound of "the door is not locked" in time to remind the door that the lock is not closed, which is not only the gospel of "obsessive-compulsive locking", but also reduces the occurrence of hidden dangers in family safety to some extent.

　　Anti-disassembly alarm

　　After installing the smart lock, many people will wonder: "What if someone directly dismantles the whole smart lock?"

　　Don’t worry! Philips smart lock has the function of anti-theft alarm. Once someone uses a tool to violently unlock the lock, when the outer panel is pried open and does not fit the door, the smart lock will give a "beep" alarm sound, which plays a deterrent role and effectively avoids the occurrence of violent unlocking behavior.

　　Not only that, the Philips smart lock supporting networking will also push the alarm information to the mobile APP in time, and the remote real-time alarm is better.

　　Protection alarm

　　If you are a business traveler all the year round, no one at home has always worried about the door lock and family safety? The protection mode of Philips smart lock allows you to feel at ease when you are away from home.

　　In the protection mode, if someone opens the door from indoors or uses tools to open the door abnormally through the cat’s eye outdoors, the lock will continuously give out a "beep" alarm sound, and the networked smart lock will also push the alarm information to the mobile phone APP in time, and the local +APP remote real-time alarm will greatly improve the safety of the home.

　　System lock alarm

　　It is clearly stipulated in GA374-2019 Electronic Anti-theft Lock that when the number of consecutive incorrect inputs of unauthorized digital keys, PIN keys and biological keys reaches the number specified in the manufacturer’s documents within 5 minutes (frequency range: 1-5), the electronic anti-theft lock should be able to give an alarm prompt or send an alarm message, and at the same time, the electronic anti-theft lock should automatically enter an invalid input state, and the invalid input state should last for at least 90s.

　　In order to prevent the phenomenon of "trying to unlock by cracking fingerprints or passwords", Philips smart lock has the function of system locking alarm. In 5 minutes, when the fingerprint, password and card are entered incorrectly for 5 consecutive times, the smart lock will lock the system for 3 minutes, and at this time, neither fingerprint nor password can be entered, adding another "lock" for home safety.

　　Low battery alarm

　　Under normal circumstances, Philips smart lock can be used 10 times a day, and 8 batteries can be used continuously for about 10 months (the actual battery life is affected by networking and other functions). It can be seen that Philips smart lock has a strong battery life, but it is easy to forget to replace the battery in time when the battery replacement frequency is low.

　　In fact, the Philips smart lock has a low battery reminder function. When the power of the door lock is less than 20%, the lock will send out an alarm prompt of "Low battery, please replace the battery" to remind you to replace the battery in time. Not only that, if the smart lock supports networking, you can also visually check the remaining power through the mobile APP, and the low power status will be pushed in real time.

　　Don’t worry if the smart lock is frequently reminded of low battery or forgets to replace the battery. Philips smart lock also has a Micro USB power interface, which can be unlocked by emergency power supply of ordinary charging treasure, which can easily solve the battery life problem of the door lock.

　　As a "home guard", smart lock has an all-round intelligent alarm system, which can effectively avoid the occurrence of abnormal damage.

　　Philips smart lock integrates multiple alarm functions such as anti-disassembly, protection, low battery, etc. Local +APP remote alarm blessing can safely put your home in your pocket and guard your home for 24 hours.

　　The above is the comparison between Philips smart lock and Samsung’s introduced by Xiaobian, and I hope it will be helpful to everyone. To sum up, comparing Samsung and Philips fingerprint locks, Xiaobian is also inseparable, because everyone’s eyes are different in all aspects, so this still depends on themselves.

　　Xiaodi S8 is a modern cloud smart lock that integrates key, fingerprint, password, gesture, shaking, clicking and other unlocking methods. It fundamentally solves the various needs of users for door locks, and also leads users into the high-tech era and feels the enjoyment of life brought by technology. Let’s take a closer look at Xiaodi S8 Cloud Smart Lock.

　　Unpacking appreciation:

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　The packaging of Xiaodi S8 can be said to be simple and not simple. With white as the overall tone and conspicuous Xiaodi logo, it looks a little small and fresh, but it is not boring. The sparse text introduction is just right everywhere, and the focus is simple and clear. The addition of telescopic plastic handle greatly increases the practicability of the whole package.

　　Finally, let’s take a look at Xiao Di S8′ s family photo. From this battle, do you feel very strong? Besides the front and rear panels of the lock body and the lock core, there are also a lot of things such as instructions for use, installation instructions, keys, batteries and accessories.

　　Design:

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　Xiaodi S8 panel is mainly made of aluminum alloy and zinc alloy, so Xiaodi S8 is quite weighty to hold in your hand. The surface of the panel is supplemented with brushed metal texture, which makes the whole look more exquisite. Compared with ordinary door locks, it is a status symbol only from the appearance.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　Xiaodi S8 is currently available in two colors: starry night silver and starry night gold. Although the color matching is not very rich, it can fully meet the needs of various security doors. The size of the front panel of Xiaodi S8 is 300*70*27mm, which is just right for any door, and it will neither be huge nor particularly small.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　The overall workmanship of the front panel of Xiaodi S8 is very fine, and both the overall design and the detail processing have reached the highest level, so that users can never tire of seeing it. Compared with other smart fingerprint locks in the market, I prefer the fresh and simple style of Xiaodi S8, which is more suitable for young people’s fashion pursuit.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　The top part of the front panel is the touch panel area of Xiaodi S8. Xiaodi S8 adopts 5A diamond touch screen, which is more sensitive to use. As long as you gently slide the touch panel with your finger, the panel will be lit up immediately, and you can easily open the door by directly inputting the set password. The "di" logo on the digital panel is a Bluetooth wake-up indicator, which is blue at ordinary times. If the battery is low, the indicator will be red.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　Below the digital panel is a fingerprint collection window. The small disco S8 adopts an optical automatic sensing fingerprint head, and the unlocking speed of the small disco S8 can be completed within 0.1s at the earliest through hieyie high-definition fingerprint algorithm. The horizontal bar below the fingerprint collection window is the small button S8 Bluetooth wake-up switch, which can wake up the Bluetooth function by pressing it lightly.

　　Xiaodi S8 adopts a solid aluminum alloy handle, and the ergonomic handle design makes the grip feel more comfortable. The junction between the handle and the panel is beautified with a metal ring for details. In the actual use process, the front handle turns slightly stiff. Besides, the most unacceptable thing for me is that I need to manually reset the handle after opening the door.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　Although Xiaodi S8 is an intelligent fingerprint lock, it still retains the key-to-key unlocking function. In my opinion, this is also a wise move. After all, there is one more way to choose. The key space of Xiaodi S8 is located at the lower side of the front panel of the fingerprint lock, which can ensure the overall beauty of the front panel and give consideration to the function setting. Adjacent to the keyhole is the USB interface, which is mainly used for emergency power supply and provides another guarantee for unlocking.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　Xiaodi S8 uses a super-B pure copper lock core, which has greatly improved the safety, and even professional locksmiths are probably helpless about it. As the key of Xiaodi S8, it will naturally not be plain. Compared with our common keys, Xiaodi S8′ s key is slightly different, not only with teeth marks on the front, but also with teeth marks on both sides, which makes it more difficult to accompany the key.

　　Full-time gatekeeper-evaluation of Xiaodi S8 smart lock-evaluation of Xiaodi S8 smart lock

　　The back of the front panel of Xiaodi S8 is also delicate, and the hole reservation is just right. The lock circuit adopts integrated line-to-line connector interface, and the outer layer of the circuit is all covered with black nylon wire sleeve, which effectively guarantees the breakage of the door lock in the use process.

　　Full-time Gatekeeper —— Evaluation of Xiaodi S8 Smart Lock

　　Compared with the front panel, the design of the back panel is much simpler. The size of the back panel is slightly larger than that of the front panel, and it is also made of aluminum alloy. However, the back panel does not use wire drawing technology, but adopts the mirror technology that is popular at present. The overall look is full of luster, just like a mirror.

　　As a smart door lock, it is naturally inseparable from the power supply. Xiaodi S8 uses two groups of 8 AA batteries as the main power supply, one of which is the power supply and the other is the standby power supply. It can be used normally as long as one group (4 batteries) is guaranteed to have electricity. There are specific battery installation methods in the battery cover, and there are three matching methods in total. The QR code user APP on the lower side of the cover is registered for use.

　　Next to the battery compartment is the anti-lock switch, which can be locked inside and outside at the same time by gently rotating the switch to the vertical direction, which provides a safer psychological guarantee for the friends who are alone at home. The rotating handle of the back panel is exactly the same as the shape of the front panel, but the handle of the back panel can be automatically classified, which is more humanized than the handle of the front panel.

　　There is also a button at the bottom of the back panel, which is used to confirm all the operations related to Xiaodi S8 fingerprint lock, such as lock APP binding, fingerprint input, fingerprint deletion, lock cancellation, etc., which can effectively prevent misoperation.

　　From the back of the back panel, you can clearly see the aluminum alloy material of Xiaodi S8, which is not only thick in material but also meticulous in workmanship, which lays a solid foundation for the excellent quality of Xiaodi S8 smart lock.

　　Finally, let’s take a look at the lock body of Xiaodi S8, which is similar to the ordinary lock body in appearance, but quite different in function. The common lock body needs the key to rotate to realize the spring-out of the lock tongue, while the small disco S8 automatically realizes the spring-out through the top two-way lock tongue. The stainless steel solid lock tongue fully guarantees the durability of the lock body. The lock body can be divided into two types: heaven and earth hook and no heaven and earth hook, which can be purchased according to the specific situation of your home.

　　When Gujia Smart Fingerprint Lock is brought back, the external lock body will not be too heavy, but it feels heavy when held in the hand. At first glance, it is made of zinc alloy.

It has a special password screen that is very clear, and it also has a night light, so sometimes you can go home at night and open the door quickly. However, I use its fingerprint to unlock the door most, because its fingerprint verification area is just on the door handle, so it only needs one hand to open the door, and it is very fast.

　　The fingerprint identification of Jiubang Smart Lock does not require a person to enter only one finger. We can enter more fingerprints, because there is no guarantee that a finger’s fingerprint will always be intact, and it may be accidentally worn or destroyed in the future, so that fingerprint identification can’t unlock.

When modifying the administrator password, you must pay attention to some key points when resetting, especially the "administrator". You should carefully enter it. If you find that the password is wrong, you can delete it and re-operate.
