For a family, the door lock is the guarantee of safety, but no matter how the traditional key is upgraded, there is a key opening, and thieves who want to break into houses can open it as long as they master the relevant technology. Faced with this situation, many door lock companies decided to combine door locks with intelligence to create door locks with higher safety factor. Yunmi Internet Smart Fingerprint Lock Link is the leader in the entry-level market of smart door locks.
Yunmi Internet Smart Fingerprint Lock Link has five ways to open the door. Different from the traditional door lock, its design is very user-friendly and the identification of biometric fingerprint module has become more accurate. In addition, its interconnection function will make smart life more comfortable. For example, when you open the door, you will turn on the lights and turn on the fans. When you close the door, you will automatically turn off the lights, turn off the fans, turn on the sweeping robot, etc. I believe this "knowing you" smart lifestyle will gradually penetrate into every household, and continue to unlock new ways of IoT scene application.
Appearance: stylish and simple, unique in shape.
The shell of Yunmi Internet Smart Fingerprint Lock Link is made of silver-gray aluminum alloy, which is simple and fashionable on the whole, not only suitable for modern simple home style. At the same time, this smart lock is made of metal, which looks very high-end and textured, and is also suitable for luxurious classical traditional home decoration style.
There are various ways to unlock.
One of the biggest advantages of intelligent door lock is that it is convenient and fast to unlock, and the safety factor is high. Yunmi Internet Smart Fingerprint Lock Link supports five unlocking methods, including magnetic card unlocking, virtual password unlocking, APP remote unlocking, fingerprint unlocking and key unlocking. It can easily cope with various common scenes in life, such as visits from relatives and friends, fingerprint wear and so on.
Hidden key panel
In order to ensure the aesthetic feeling of the door lock, the password button of Yunmi Internet Smart Fingerprint Lock Link adopts a hidden design, which can only be lit when the user touches it in touch mode. In daily situations, the door lock without the password button has achieved better visual effect. Next to the digital buttons, there are also prompt button areas for three function buttons: away from home mode, IC card swiping area and doorbell.
Unlocking semiconductor active fingerprint
In the use of smart door locks, fingerprint unlocking is the most commonly used way. Yunmi Internet Smart Fingerprint Lock Link adopts a high-precision living biometric fingerprint module, which can prevent false fingerprints. At the same time, it has a built-in Yunmi intelligent algorithm, and the fingerprint is self-learning and the recognition speed is getting faster and faster. The fingerprint identification design of the hidden handle can identify the fingerprint 360, and the area is 15.9mm? The fingerprint identification module is naturally integrated into the handle, and the step of unlocking and opening the door is completed at one go by pressing and twisting.
If the door lock is out of power and other unexpected situations, mechanical unlocking will become the only way to enter the door. Yunmi Internet Smart Fingerprint Lock Link is designed with a hidden mechanical keyhole, and an interface with emergency USB charging function is installed in the protective case. Just press the bottom of the keyhole protective case to open the protective case, even if the door lock fails, it can ensure that you can go home safely.
Class c lock core key+
At present, the C-class lock is the lock with the highest security level, and it takes at least 270 minutes to crack it. The A-class can be cracked in less than 1 minute at the earliest, and the B-class lock can also be unlocked in 5-120 minutes. It can be seen that class C lock can protect our family property well. The smart fingerprint lock Link of Yunmi Internet also has a mechanical lock in its design. In order to ensure safety, it uses a mechanical lock body with a real ferrule and a C-class lock core key, which takes at least 5 hours to crack. Even if criminals destroy the whole front panel by violence, they still can’t open the door lock, leaving criminals with no choice.
Many readers and friends don’t know what a real mortise lock body is. Simply put, the mortise body of a real mortise lock runs through the door body, while the whole mortise of a fake mortise lock is located on the outside of the door. The structure of the mortise-driven lock tongue is relatively simple, and if the front panel of the door lock is removed or damaged, the exposed lock tongue can be unscrewed only with a word screwdriver, and the door lock is useless.
The door lock of Yunmi Internet Smart Fingerprint Lock Link includes three parts: battery compartment, cat-eye-proof door handle and internal lock knob.
Inside door lock
In real life, guests and hosts will communicate at the door, so the door lock has a built-in human voice interaction system, and the back of the door is naturally equipped with speakers and other hardware devices, which can provide voice guidance for everyone when using, such as door lock setting, doorbell, door opening and so on.
The battery compartment shell is detachable.
When we disassembled the top detachable shell, the battery compartment, speaker and two function buttons were all present. Four No.5 batteries can be placed in the battery compartment, and if the door lock is opened 10 times a day, it will be enough for 12 months. However, in order to avoid the phenomenon of insufficient power or battery leakage, it is best to replace the battery once every six months. The speaker of Yunmi Internet Smart Fingerprint Lock Link is loud, and users outside the door can clearly hear the instructions. If there is a problem with the door lock, press the Reset button at the bottom and the horn on key to reset it.
In terms of security, Yunmi Internet Smart Fingerprint Lock Link adds a cat’s eye unlocking design, and the door can be opened only by pressing the handle button in the door at the same time, preventing the door lock from being opened through the cat’s eye reaching into the object, and preventing children and pets from opening the door by mistake. There is also an inward-rotating button switch at the bottom, and multiple guarantees are only for the safety of you and your family.
Design of lock tongue of anti-pick lock
For the door lock, the lock tongue of the lock core is very important, so Yunmi Internet Smart Fingerprint Lock Link adds the functions of windproof and pickproof lock tongue. Because the fingerprint is always in the user’s hand, the significance of wind protection is not great. However, it is very important to prevent the lock-picking behavior of the card face to open the door. With the configuration of the anti-picking lock tongue function, this situation will naturally not occur.
Yunmi gateway
Not all fingerprint locks belong to smart door locks. Smart door locks need to be interconnected and can be controlled by mobile phones. A door lock needs to be interconnected, usually with a corresponding gateway, or the door lock device has WiFi function. Gateway is a device that provides network connection function for low-power devices, which facilitates all devices to be networked, and together with other household appliances, achieves the effect of whole house interconnection. Yunmi Gateway is small in shape, and it can cooperate with Yunmi APP and Yunmi-related Internet appliances to realize the intelligent interconnection function of the whole house.
In the eyes of many people, the Internet is very developed now, so why does Yunmi need to configure an additional gateway? At present, smart door locks are mainly interconnected by Bluetooth, zigbee and Wifi. The biggest drawback of Wifi is its high power consumption, which affects the battery life of smart door locks.
The effective distance of Bluetooth is less than 10 meters, so it is not stable enough when connecting. Zigbee can be said to be the best solution among the three. Although it needs the support of gateway, it has low power consumption and the connection distance can reach 100 meters, and the endurance and networking stability can be guaranteed. Although the smart door lock Link of Yunmi Internet needs the cooperation of Yunmi Gateway to be used better, in fact, even without it, the smart door lock can also complete basic operations in daily life, so the gateway can be considered as unnecessary hardware.
Is there a difference between gateways?
In addition to preventing violent unlocking, compared with traditional mechanical locks, smart door locks should also prevent cracking by scientific and technological means, which is what we usually call black box cracking. Black box is essentially an electromagnetic pulse circuit, which is mainly used to produce ultra-high voltage but low current and high frequency AC power. The function of the black box is to power on the door lock control chip through the ultra-high voltage generated instantly, so that the current flowing through the chip itself will increase instantly at a certain time point, which will lead to problems in the control chip. From light to light, the self-protection mechanism will be started to restart actively, and from heavy to breakdown and burning. In this way, the lock tongue of the door lock will automatically bounce off and break itself. Yunmilink smart fingerprint Link can prevent the attack of small black box.
Test: Excellent professional quality, more interesting to use with smart home.
True and False Fingerprint Test: This test mainly tests whether the smart door lock will misjudge the true and false fingerprints under normal circumstances. After 20 tests, the unlocking rate of true fingerprint identification is 100% and that of false fingerprint identification is 0%, so users can use the lock with confidence.
Unlocking time test: This test mainly reflects the time required to unlock the lock body of the smart door lock after the user’s fingerprint covers the fingerprint identification device. After testing, the fastest time is 1.29 seconds, and the unlocking can be completed within an average of 2 seconds without any delay.
Sensitivity test of key on password panel: In the user experience, the sensitivity of key response is very important. Some smart door locks are slow in response, low in sensitivity and even have elegant numbers, which seriously affects the user’s use. After 200 uninterrupted touch tests, the response speed of the smart door lock is still fast as a whole, even if the key is pressed quickly, it can respond accordingly.
Virtual password: users can enter 22 invalid digits before and after the correct password when using the password to open the door, so as to avoid the door lock password being leaked.
Intimidation fingerprint: When the user is forced to open the door under duress, the method of unlocking by coercion fingerprint can be started, so that the door lock will send an alarm message to the APP when opening the door. When using, you need to press the number 5 for a long time, then verify the administrator password, and finally enter the coercive fingerprints (up to 5).
Temporary password: if a friend comes to your house to play temporarily, but you are not at home. At this time, you can enter the management background through the mobile APP and press the 1+# key to set a temporary password. Each password has an unlimited validity period, but it is only allowed to be used once.
Spare key: After all, smart door locks still rely heavily on the support of electricity to unlock them. In extreme cases, we can still unlock them by physical means. The door lock is equipped with a spare emergency key, and the keyhole is hidden in a rubber sleeve under the outer door lock, but this is also an emergency measure. In most cases, even using USB mobile power supply can make the smart door lock have enough power to open the door.
If it is matched with Yunmi Gateway and other smart devices of Yunmi, users can set up their own IoT scenarios. For example, the home mode will automatically turn on the lights, TV sets, air conditioners and other electrical appliances at the moment you unlock the lock; Leaving home mode will turn off the lights, turn off the air conditioner and turn on the sweeping robot after you close the door to create an energy-saving and comfortable home for you.
