I still remember when I was in primary school, my mother was afraid that I would lose the key of my home key, so I tied a rope on the key and let me hang it around my neck. However, now, such scenes are rarely seen in children. Because the smart lock with the aura of science and technology has gradually replaced the traditional door lock and become the first intelligent guardian before we enter the family.
Indeed, compared with traditional door locks, smart fingerprint locks have more and more convenient ways to unlock. For example, when you go out, you don’t have to touch the keys in your pocket or bag from time to time to see if they are still there. For example, when you open the door to sign for the express delivery, even if the door is accidentally closed in the strong wind, you don’t have to pat your thigh in annoyance, let alone spend money to invite the locksmith to your door. No, when I got "what a painful understanding" again, I also started a smart fingerprint lock, which is the latest intelligent lock K5 of the Internet of Things launched by TCL. Next, follow me to see its performance.
I don’t need to go into details about the outer packaging. Two cowhide cartons, with thick sponge protection inside, are enough to ensure the TCL K5 smart lock to reach my home safely. According to international practice, let’s start with a family photo: front panel, back panel, lock body, lock core, two keys, two magnetic cards, eight 5th batteries, slub screws, square shafts, connecting studs, cotter pins, picks, installation instructions and instructions for use, etc. Many parts are also complete.
In the past, perhaps many people would put on a magnificent security door to emphasize their "face project". However, the key to measure whether frontispiece is tall or not has shifted from the security door to the smart door lock. After all, the door lock is the security guard of our family, and at the same time, the first impression it gives directly reflects the owner’s taste. Obviously, TCL manufacturers have also considered this. Domineering and steady titanium black tone, fashionable sliding cover design and the handle that can be opened at once not only make the appearance of K5 more textured, but also give consideration to comfort and convenience.
I want to give a close-up of streamline surface design of TCL K5 smart lock. Because the unique lines of the fuselage are very delicate whether viewed from the front or the side. According to the official introduction, its design is inspired by high-end sports cars. Well, no wonder K5 looks so cool. In addition, since K5 is made of aluminum alloy+zinc alloy, there is no need to worry that its panel is easy to scratch, and there is no need to worry that its shell will rust or corrode in a humid environment like my home or other cities with high salt content.
In other words, only by sliding the upper cover can the password function and the card swiping function be used. Personally, such a hidden design can not only make the touch-sensitive keyboard area better protected against dust, but also improve the safety index. The only thing that bothers me a little is that the slider is easy to be contaminated with fingerprints. After each use, I can’t help but wipe the slider to a polished state with obsessive-compulsive disorder.
Seeing this, do you want to ask, the fingerprint module is not in the slider, where is it? Knock, knock, knock! The circular area at the front of the handle is the fingerprint module you are looking for! Sticking your thumb to the fingerprint module while holding the handle, TCL K5 smart lock can quickly identify our fingerprints, and you can open the door immediately by pressing the handle, which is worry-free and convenient.
Of course, as a fingerprint lock, it is not enough to emphasize convenience, but also to have accurate recognition ability in order to get unanimous praise from everyone. Otherwise, if you have to try several times to identify success every time you open the door, it is really hard to use. The fingerprint recognition area of TCL K5 is the largest among the products I know at present, and the fingerprint image recognition density is 192*192, while the products on the market are generally 160*160. The larger fingerprint contact area will naturally bring faster recognition speed, and the TCL K5 smart lock adopts the Dutch NXP fingerprint algorithm with a fingerprint error rate of less than 0.001%, which can be used not only in wet and dry hands, but also with extremely fast recognition ability.
Whether you use fingerprints to unlock, or enter passwords, swipe cards and remotely unlock the APP, you need smart locks with sufficient power support. Although the manufacturer is equipped with eight batteries, an emergency power supply port is set at the bottom of the outdoor panel just in case, in order to provide emergency power supply for the K5 smart lock of TCL Internet of Things.
The silicone protective sheet integrally formed on the back can not only protect the door panel, but also improve the fit between the door body and the door lock. In addition, there are many raised particles on the edge of the silicone protective sheet, which are actually fixing buttons, which can firmly fix the silicone protective sheet on the door lock.
The inner door panel is also a cool line and surface design. In addition, the back cover of TCL K5 smart lock is integrally designed for installation reasons. In other words, if you want to replace the battery, you need to tilt the cover at the bottom to find the battery compartment.
The battery compartment of TCL K5 smart lock has 8 battery positions. In fact, only four batteries are enough for normal power supply, and the other four are spare batteries. In normal use, if the battery with normal power supply is insufficient, the spare battery will automatically top up.
The rear handle has a raised button, which can prevent unlocking through the cat’s eye. Therefore, if you want to open the door and go out, you can’t open the door by pressing the handle directly. You need to press the button and then turn the handle to open the door.
At the bottom is the lock knob. Remember to press lightly before turning, otherwise, the anti-lock knob cannot be turned.
The standard lock body of TCL K5 smart lock is made of stainless steel SUS 304, which supports the linkage between heaven and earth.
The lock core is a class C true ferrule made of all copper. There are two keys, which can be folded and put away at ordinary times.
By the way, there are a number of screw fittings.
Because it involves wiring and debugging, professional masters are needed to install fingerprint locks. Here, I want to praise the master who installed the lock: from unlocking to installing, the master is very careful.
In addition, in the process of installation, the master also used a ruler to measure the distance between the upper, middle and lower parts of the inner and outer lock bodies and the door many times to make sure that the door lock is installed correctly and straightly.
In order to make TCL K5 smart lock realize more intimate and convenient functions, there is no need for the support of mobile APP.
The APP of TCL K5 smart lock is called "Little T Zhilian", so the installation method and registration method are not detailed here, just follow the relevant prompts to complete it. However, in the APP, in addition to setting up and receiving information, you can also create a unique smart life with the Internet of Things.
Experience:
1. Let’s talk about the fingerprint experience. I believe everyone, like me, as long as the fingerprint lock is mentioned, whether it is expensive or entry-level, what we want to know most is whether its fingerprint recognition function is strong or not. However, you can’t find an accurate answer just by looking at the product introduction of the network or asking others before you experience it yourself. After all, the introduction of products by merchants, especially the introduction of parameters, is abstract to ordinary consumers. Moreover, no merchant will think that his own products are inferior to others. Therefore, if you want to know whether it is a mule or a donkey, you have to walk around in person to know.
Frankly speaking, after using TCL K5 smart lock, I know why this password lock emphasizes the fingerprint widening area. First of all, when entering fingerprints, the door lock will prompt you to enter many times by voice, with the aim of improving the accuracy of fingerprint identification by collecting fingerprints from different angles. Therefore, when you unlock the lock, you will find that every time you use your fingerprint to unlock the lock, you will almost pass it once, and there will be very few voice prompts that need to be re-recognized. In addition, while recognizing the fingerprint, there will be an indicator light above the handle to remind us of the fingerprint recognition status, which is intuitive and convenient.
2. Unlocking mode. There are six ways to unlock TCL K5 smart lock: fingerprint, password, card, key, APP remote unlocking and temporary password. The first five methods can be set by yourself on the door lock, and the temporary password should be set directly in the mobile APP. It is mainly convenient for relatives who come to stay at home for 2 days or when we are not at home, relatives and friends suddenly visit.
Among them, password unlocking and card unlocking need to open the slider.
After use, K5 smart lock detects that we don’t operate in the keyboard area within 10 seconds, and the slide will slide down automatically. Personally, I think this function is very user-friendly.
The lock hole is under the handle, so you need to open the cover before using the key to unlock it.
3. APP function. Perhaps it is because it has become our daily life to use APP to control other smart devices, so many product settings need to be completed on APP. However, in the main page of "Little T Zhilian" K5 smart lock, there are not many related function operation tips. For example, adding an administrator, setting a password, adding a key card, deleting a key card, etc. can all be set according to the voice prompts on the keyboard area of the K5 smart lock. Even if it includes remote request for unlocking, you need to press "8"+"#" on the door lock first, and wait for the APP to receive the push information before you can perform the corresponding unlocking operation. Looking at it from another angle, this way of operation and setting does not diminish the role of APP, but can ensure that the door lock can also be used and operated when it is not connected to the Internet. Even if the home is suddenly disconnected from the Internet, the setting and use of K5 need not rely on APP.
In addition, considering the power consumption caused by the long-term connection between the mobile APP and the door lock, the door lock will send an offline reminder. Don’t worry, the door lock will automatically go online after opening the door or the sliding cover.
TCL K5 smart lock has a function that I must praise: reminding push when the door is not closed. Frankly speaking, I have the legendary obsessive-compulsive disorder. Every time I go out, I always doubt that I have not locked the door firmly at the moment when the elevator closes and goes down. Then, during the elevator running to the first floor, I will have an ideological struggle as usual. Then, after arriving at the first floor, I will continue to stay in the elevator and press the floor where my home is, and go back to check it out. To tell the truth, obsessive-compulsive disorder is really tiring. However, such embarrassment has never happened since K5 was installed.
Because its lock body has a deadbolt safety sensor, if K5 detects that my door is not fastened within 30 seconds after opening the door, that is, I am still waiting for the gap of the elevator, the mobile APP will immediately receive the pushed safety warning information, and I don’t need to go up and down the elevator frequently to check and confirm. Also, every time you enter the APP, you can see whether the door is closed or still open on the home page.
Summary:
TCL K5 smart lock has a unique shape, especially the streamlined curved surface design makes this door lock look more tall and elegant. In addition, the K5 smart lock also has a C-class true-inserted lock core, an oversized fingerprint identification module, an unlocked door reminder push function, an anti-hijacking fingerprint alarm function and six intimate unlocking methods, which not only ensures the safety and convenience of the door lock, but also realizes more humanized operation functions from the user’s point of view. I wonder if TCL K5 smart lock is also your dish?
