As a product of smart home category, we have stricter requirements for smart door locks than other home products. Why do you say that? Because smart door lock products are not only smart and smart enough, but more importantly, the safety guarantee should be in place. After all, it is the first line of protection for family safety. However, when the smart door lock products just emerged, the quality of the products can be said to be uneven. Some of them are not beautiful and easy to use, and they can even be cracked by small black boxes. It can be said that many buyers have become mice.
This time we are evaluating a smart door lock from Lenovo, model E1. Lenovo also makes smart door locks? Yes, Lenovo has entered the smart home industry in recent years, and has launched many products that are deeply loved by consumers, especially the smart door lock product category, and launched many models, and Lenovo smart door lock E1 is the new product promoted by Lenovo at present.
Not cold design
First of all, in appearance, the Lenovo smart door lock E1 still looks very fashionable and versatile. The color matching of the inner and outer panels is black, and both of them adopt the 2.5D cutting mirror panel, which is integrated and has some sense of quality. For most consumers, it should be more in line with the style of the door at home.
It is said that technology is developing so fast that there is no warmth but only a sense of coldness, but Lenovo smart door lock E1 is not so cold. Its inner and outer door handles are decorated with wood grain design elements, which makes the whole door lock panel look less monotonous and more beautiful.
In addition, the handle of Lenovo smart door lock E1 is still inclined at 20. When you open the door, the design of the handle is more in line with our usage habits, and it is more comfortable and user-friendly. Although these are only small details, they greatly enhance the experience.
The handle of the door lock on the outer panel adopts a fingerprint head with a large size of 192×192. Such a large identification area is more conducive to the accuracy of fingerprint identification, and even people with shallow fingerprints such as the elderly or children can easily identify the lock, which is especially suitable for a family. In addition, it supports up to 100 groups of fingerprint input, and the capacity is large enough to input more than one finger’s fingerprint. Above the handle is the digital touch button area and the card swiping area, and below is the key cover, where the emergency keyhole is hidden.
The handle of the door lock on the inner panel is also hidden. A cat’s eye unlocking key is integrated on the handle, and an anti-lock knob is located below the handle. The knob is also designed to prevent accidental touch, and it can only be turned after being pressed down, so as not to be afraid that Xiong Haizi at home will lock the door lock at random.
By the way, the battery compartment of the door lock is hidden under the integrated panel, with a total of 8 batteries. The batteries have been given in the attachment and are ready to use. Eight batteries are enough for a long time, and there is a Micro USB emergency interface at the bottom of the outer panel. Even if the battery is low in power, it can be directly connected to the mobile power supply through the interface for temporary power supply. In terms of appearance design, I personally prefer Lenovo smart door lock E1, which adopts many hidden designs and considerate small designs to make it beautiful enough.
Lenovo smart door lock E1 has good compatibility with doors, and supports heaven and earth hooks. Whether it is a security door or an ordinary wooden door iron gate, the door thickness can basically be installed within the range of 50 to 120 mm. Moreover, Lenovo also provides professional personnel to install door locks at home. Before installation, it is convenient to take a few photos to confirm the parameters of the door.
In the accessories, we also see that Lenovo’s smart door lock E1 is equipped with a C-class plug, which is the lock core with the highest safety factor at present, and the technical unlocking time can reach more than 270 minutes.
Intelligent and easy-to-use unlocking method
In addition to being beautiful, smart door locks must be smart enough. To put it bluntly, intelligence is easy to use. For example, if you forget your key, you won’t be at a loss because you can’t open the door. Next, let’s talk about the unlocking method of Lenovo smart door lock E1. In the unlocking method, Lenovo smart door lock E1 mainly has four unlocking methods: fingerprint identification, digital password, encrypted magnetic card and emergency key.
The most convenient and quick way to unlock is fingerprint identification. As mentioned earlier, Lenovo Smart Door Lock E1 has a fingerprint head with a large size of 192×192, and the identification area is about 25% higher than the industry average, so the improvement in recognition rate is also very obvious. Official data shows that the recognition rate can be improved by more than 5%, and the speed of unlocking recognition is less than 0.1s The most intuitive performance in the use experience is that it is accurate and fast when unlocking.
In addition, it also has the function of intelligent updating of fingerprint information. Simply put, it can refresh and improve the previously stored fingerprint information every time fingerprint identification is carried out. Therefore, when you use fingerprint identification to unlock more and more, the fingerprint identification speed and accuracy of Lenovo smart door lock E1 will become faster and more accurate.
Not only that, Lenovo smart door lock E1 can input up to 100 sets of fingerprints, and with the financial-grade living fingerprint module, it is more excellent in security.
There is also breathing light in the circle of fingerprint identification. White means the door lock wakes up, green means the fingerprint verification is successful, and red means the verification is failed.
According to the actual experience, the accuracy and reaction speed of fingerprint unlocking of Lenovo smart door lock E1 are still very fast, which is basically that it is opened after contact. Because the recognition area of fingerprint module is larger, it is not necessary to be careful when putting your finger on it, and the whole unlocking process is easier. Moreover, with the increase of the number of uses, more and more information is stored in the fingerprint module, and the accuracy of fingerprint unlocking is slowly improving. I don’t feel the improvement of unlocking speed obviously (because the unlocking speed is already fast), but the accuracy of unlocking is real. Sometimes, although the finger deviates from some positions on the module, it can be unlocked smoothly.
In addition, the way to unlock the digital password is also interesting. You can set a password of 6 to 12 digits, but you can enter any number within 30 digits when entering, as long as there is a correct password in these numbers. For example, if the password I set is "456789", then I can open the door lock by typing "123456789" or "456789123". The advantage of this virtual password function is that it can prevent outsiders from secretly writing down the password when you enter it, which is more secure.
Encrypted magnetic cards and emergency keys are rarely used to unlock doors for me. Lenovo also presented two encrypted magnetic cards and emergency keys in the attachment. After all, it is not so convenient to carry a magnetic card and a key with you. Unless an emergency key is needed in extreme circumstances, I personally feel that fingerprint unlocking and password unlocking are more convenient and applicable to more people. But in general, Lenovo smart door lock E1 is still very smart and convenient to use, which can let you bid farewell to the dilemma caused by the inconvenience of traditional door locks.
The most important thing is safety first.
What is the most important thing about smart door locks? The most important thing is of course safety! After all, there are many times when only the elderly or children are at home during the day, or even no one is at home at all, so the safety of the door lock must be guaranteed enough!
Lenovo smart door lock E1 comes standard with a C-level plug, even if the thief removes the front panel of the door lock, there is no way to take it. Here, I would also like to share with you what a C-class lock core is. Generally speaking, a C-class lock core is the lock core with the highest protection level. The keyway is single-sided or double-sided with two rows of concave and S-shaped, or the internal and external double-snake-shaped internal milling groove structure. The technical opening time is at least 270 minutes, which means that it will take a professional thief more than 4 hours to pry open the lock. Therefore, the security of Lenovo smart door lock E1 is absolutely reassuring.
Lenovo’s smart door lock E1 also has a cat’s-eye-proof button, and the door lock can be opened only by pressing the button. In addition, the door lock also supports prying alarm and trial opening alarm, which can be said to be the ultimate in safety performance in all aspects.
Turn the internal measuring knob to realize internal anti-locking.
Before going out, lift the handle outside to pop up the locking bolt for locking.
Of course, we also conducted a small black box test. The small black box can interfere with the internal circuit of the smart door lock by using high-frequency and high-intensity electromagnetic pulses, thus providing a way for criminals to destroy the door lock. After our actual test, Lenovo smart door lock E1 has passed the test of small black box well.
Through the animation, we can see that the small black box has no response in most areas of the door lock, and only has some effect in the digital button area, but only the backlight lights up, and there is no other abnormal situation. It can be said that Lenovo smart door lock E1 resisted the electromagnetic pulse of the small black box and passed the test of the small black box perfectly.
Summary:
As a smart door lock, Lenovo smart door lock E1 has excellent performance in appearance, unlocking mode and safety. If you are still using traditional door locks at home and want to choose a smart door lock to enhance the safety and ease of use of the door lock, then Lenovo smart door lock E1 is definitely a product worth considering. After all, Lenovo’s quality assurance+product performance really makes it very competitive.
