On how to complete the comprehensive evaluation of Zhengtai smart fingerprint lock on the sofa

With the development of technology, smart devices have gradually extended from the digital field to the home field, and a variety of smart home products emerge in an endless stream. Among them, the more practical and easy to use is the smart door lock. As the first line of defense of the home, the door lock has always been responsible for the guard house. What is the difference between a door lock that incorporates the concept of intelligence and an ordinary door lock? The fingerprint lock produced by Chint Group, ranked fourth among the top 500 private enterprises in the country, can give you a good answer. Thanks to the trial opportunities provided by Yizhi Mushroom, I can experience a well-made and powerful smart lock.

The whole box is rectangular, dark blue, weighs 3 kg, with a handle, and the right upper corner is printed with CHNT, which is abbreviated as CHNT. The color is relatively dark, which is not so good. It may be relatively low-key. In the lower left corner, Chinergy Smart Lock is clearly printed. It seems that it should be a sub-brand of Chint, which is dedicated to smart lock business.

The side of the box is a more detailed product information, including the specific model Chinergy-Lock-00203, as well as the appearance, fingerprint, function, color confirmation, this smart lock has two colors of red bronze and champagne gold, can be based on their own The color of the door is matched and selected.

The inner packaging can be said to be patchwork. The protective frame made of foam plastic covers the various components of the smart lock well to ensure the safety during transportation. On the outer box map, you may see some violent express delivery in the upper left corner. Scars, but without any damage after opening, the entire package is very strong.

After all the components were put out, it was full of dumplings, and the names were marked on the map. I typed in the province.

I almost forgot something more important. The fingerprint anti-theft lock is equipped with a hole size template and a detailed instruction manual. The former is used when the lock body is installed, and the latter is used when it is used.

First look at the lock body used by Chint, 304 stainless steel material, standard 6068 three anti-lock body, adapt to most security doors on the market.

The flat anti-collision lock tongue has a length of 55mm and 11mm respectively, preventing violent impact. Compared to the common three-column style, the one-piece design is more robust and durable.

The anti-locking tongue has a length of 21mm, the width is consistent with the anti-collision lock tongue, and is used for the internal anti-locking of the door, and the bolt sleeve prevents the sawing.

The product certificate on the lock body, as well as the self-contained heaven and earth hook, with undulating grooves, can be better connected for the security door with this function.

The movable lock tongue, windproof and anti-mite, has a silent patent, and the opening and closing room is quiet. Also using high quality 304 stainless steel, rust-proof and durable, durable.

This bolt can also be adjusted according to the direction in which the door is opened and closed. It is easier to understand how to make the movement of the lock inside and outside the lock. The tools needed are just a flat-blade screwdriver. When swapping, the right thumb pushes up the fixed block, and the left hand pushes the lock tongue into the steering area with a screwdriver. After rotating 180°, the lock tongue is ejected and the interchange is completed. Since my home is left open, the locks that are sent need to be interchanged. This is the first interchangeable part of Chint Smart Lock.

Corresponding to the lock body, there is also a frame piece for mounting on the door frame, which reduces the gap between the lock tongue and the door frame after locking, and increases the safety factor.

Then look at the front and rear panels, this is the front panel, there is no power, the touch area is not glamorous, the lock core is installed in the center of the panel, and it is also the place to install the handle.

The speakers on both sides, the voice prompts of the smart locks are spoken here.

Then look down, here is the essence of the smart lock, fingerprint identification area, using optical sensing technology to identify, long life, stability, durability and damage resistance are significantly enhanced, ah, still no power, first Take a look, the two small cymbals at the bottom of the front panel are emergency power connectors, which will be mentioned a little.

Let's look back on the back panel, here is the battery compartment for installing 4 AA batteries to provide power for the entire smart lock.

hold. The mounting handle is the same as the front panel.

Below it is the menu button, the anti-lock button and the factory reset button hole.

Speaking of the handle, Chint's smart lock adopts the interchangeable design of the handle. Like the movable lock tongue, it is very convenient to adjust and install according to the opening and closing direction of the door. This is the second interchangeable part of Chint Smart Lock.

The third interchangeable part of the Chint smart lock is the place where the front axle is mounted with a large shaft, that is, where the handle is rotated. The installation direction is selected according to the left and right indications of the rubber washer and the arrow indication of the connection. The three interchangeable parts can be used in combination to adapt to all four door opening directions. It is very user-friendly. Consumers do not have to consider whether their doors are left or right when they are purchased. Buy them and adjust them according to actual conditions. That's it.

In addition to this part, the front panel has a data cable that is used to connect to the rear panel to transmit power and related data.

The hardware part of the whole smart lock is almost introduced here. Next, we will enter the installation stage. Before talking to the customer service of Jingdong Zhengtai, the manufacturer provides free on-site installation, but if it is installed by itself, you can apply for cashback 200. As far as my installation experience is concerned, as long as the door of your home is not very grotesque, you can complete the installation by yourself. I will explain the installation process a little. Interested friends can find out if they can understand. Leave a message, let's discuss together and study together.

In order to more intuitively display the entire installation process and subsequent evaluation content, I want to sacrifice this important supporting role, that is, the anti-theft lock frame, people who have visited the home store should see this in the shops selling security doors. Something is a tool used by merchants to display anti-theft locks. When I bought it, I also looked at the size. The feeling is similar to that on the opening size chart, so I bought it. It turns out that Chint used the standard 6068 lock body. , or a match.

Some of the installation process is not very important, it will be skipped directly. Otherwise, this evaluation is too lengthy. First, put the stainless steel lock body into the lock frame, fix it with the screws in the parts package, and then start installing the front and rear panels. First install the generous shaft on the front panel, as well as the upper and lower connecting rods, which are the key components for connecting the rear panel.

When installing, the data cables must also pass together. The nylon protective cover can prevent the data cable from being damaged when it passes. At the same time, install the fixing plate of the rear panel and see that the yellow screws next to the data line are not available. Two kinds of screws of different lengths are provided in the parts pocket, and the appropriate screws can be selected according to the thickness of the door of the house.

Then connect the data cable to the rear panel, modular design, and then insert it gently after inserting it. Those who often toss the computer should be familiar with this excuse. Observing a close friend may have seen the fake lock interface on the left, and I don't know its specific function yet.

Then put the rear panel horizontally down. Here is a very important place to pay attention to. This is the connecting rod connecting the anti-lock button. In order to adapt to the door of various thicknesses, the connecting rod adopts a breakable design. The thickness of the door is cut off by itself. The thickness of this lock frame is 5 cm, and it can be seen that it is about 2 cm long, so it needs to be cut off.

If you can't determine the exact length at a time, you can cut off a small section at a time, put it in and try it a few times, and the length is right. It's better to cut it a little more, or it will break the fingerprint of the front panel. There are also related tips on the pole, please be careful when operating. During the entire installation process, this is a place that requires more patient debugging and is the only one that is a bit difficult.

Then put on the back panel and screw a few screws. The bronze that peeled off the protective film is pretty.

Putting on the battery is done, and the Nanfu battery with the energy-collecting ring is also a familiar domestic brand. The four-cell battery can provide up to 6,000 lifespans. It can be used for 20 times a day, and it can last for nearly one year. Time, saves you the trouble of replacing the battery frequently.

First come to light a phase, in fact, the entire lock body is still relatively large, after all, in addition to the conventional mechanical components, also added a lot of electronic components.

Especially this 2.0-inch high-definition large screen, the resolution is 160*120, the operation of the whole display display combined with voice playback, the combination of graphics and text has become less important.

When viewed from the side, it is also quite thick, as long as the thickness of your door is more than 125px. If it is smaller than this size, the large axis should be cut.

The general home security lock basically needs to use the key if it needs to be locked, but the Chint smart lock integrates the function of locking and unlocking in the handle, and the handle is locked on the handle, and the handle is unlocked. Convenience. The door is the same outside the door, of course, you need to use a fingerprint or password to unlock from the door.

The role of the anti-lock button does not need to say more, the obsessive-compulsive patients must be locked at night to sleep peacefully.

Chint Smart Lock provides 6+1 unlocking methods, including fingerprint, password, IC card, mobile APP, 4 kinds of single open mode, and two combinations of fingerprint + password, password + IC card. In terms of security, It can be said that it has done its utmost. The last traditional mechanical key is also used only for emergency use. However, Chint is equipped with a C-class lock cylinder, the blade is specially designed to prevent technical unlocking, and the lock core is hidden in the handle.

I made a picture of everyone to feel that when using the key to open the door, it is also necessary to hold down the pressure and retract the lock tongue.

The reason why Chint is hiding the keyhole is so that you can forget the existence of the key and switch to other more convenient unlocking methods, such as fingerprints. Seeing this pass-through fingerprint collection area, is there a feeling of Green Lantern?

The first thing to turn on the power is to change the initial password, thanks to the high-definition display of the 2-inch large screen, and clear voice prompts, after which all operations can be done on the smart lock. First of all, I completed the entry of the administrator's fingerprint. The steps are relatively simple. Press the menu button on the rear panel to enter the setting interface. At this time, the 2 and 8 of the numeric keypad area on the front panel correspond to the up and down keys in the display, * The # and ## are correspondingly canceled and determined, and it is very convenient in operation. After entering the factory password of 6 0, you can operate according to the text prompt. Chint smart lock supports the creation of 3 administrator fingerprints and 107 ordinary user fingerprints. It can be seen that Chint hopes that users will use fingerprints to unlock.

Recently, my fingers are a bit suede, Chint can also be very quickly identified and entered, and correctly read and matched in the subsequent unlocking, no strong hardware support is absolutely impossible.

You can create a user, of course, you can also delete the user. Just enter the ID number you want to delete in the delete interface, or select to delete all the fingerprints. You can do it. After that, the password and IC card operation are the same. I won't Repeatedly displayed.

The premise of using the fingerprint to open the door is to activate the door lock, gently push the fingerprint head protection cover, the door lock is activated, put the finger in the fingerprint recognition area, wait a moment, and when you hear the voice prompt, you can press the handle to open the door.

Chint smart lock also uses a free handle, which means that the handle is in a free state after locking. At this time, the handle can be pressed but the door cannot be opened, which effectively protects the mechanical parts inside the lock body from being violently damaged.

In the fingerprint unlocking, there is a function called hijacking fingerprint. As the name suggests, when someone uses this fingerprint to open the door lock, the system will think that a hijacking event has occurred and push the alarm at the first time. Here are two keywords, the network and the APP. The smart lock push requires the network, and the mobile phone receives the push and needs the APP to download and register by scanning the QR code on the manual.

The menu button in the upper right corner has some common functions. The first thing to do is to configure WIFI. This time, you need to use smart lock.

The configuration of WIFI is also a binding to the mobile phone number. After that, all the information on the smart lock can be viewed on the mobile phone APP, and the concept of intelligence is well reflected.

Among all the functions, I think it is more magical and special is the anti-hijacking function. Fingerprints and passwords can be set to hijack users. When using the set fingerprint or password to unlock, the smart lock will push the alarm information to the mobile phone synchronously. In the APP, the phone will continue to vibrate the alarm until the app is clicked and the hijacking alarm is turned on.

Password unlocking, I think Chint does not push this function. From the number of registered users, it is far less than the fingerprint user. The common password plus the hijacking password plus the remote opening request password, the total number is only 11 groups, may be Zhengtai I don't want users to enjoy a convenient life, but also have to bother to remember an extra password, and the process of opening the door with a password is more complicated. First, touch the button area to activate the smart lock, enter the 2-digit confirmation code, although it is for Prevent misuse, but one more step will affect the experience, then the correct password input, and finally need to press the # key to determine, it can be said that password unlock is the most troublesome of all the ways.

However, in the password opening, there is a remote opening request password, which is more suitable for relatives and friends to come over. If the owner happens to be away from home, the guest can first open the door to enter the house. In this regard, I also recorded a small video to demonstrate this feature, before I have set up the remote open request password 9527, people who like the star should be familiar with this number.

By the way, there is a dummy password in the password function. Simply put, just enter the number before and after the correct password to achieve the purpose of disturbing others. It reminds me of the movie that the gangster opened the safe and the younger brother turned silently.

After the fingerprint and password functions have been said, let me talk about my personal favorite IC card opening function. Chint provides 3 cards in the package for consumers to use, which is enough for the average family. Compared with the Bluetooth keys used by other brands, Chint Smart Lock does not have to worry about the power of the card, but also saves effort.

The bonus card needs to be registered in the main menu before it can be used normally. Unregistered cards will show verification failure.

The card mode is more suitable for the elderly in the home. Their fingerprints are not so clear and complete. Secondly, they may not remember the unlocking password and the complete unlocking process. If the card is used, the main screen will have a swipe icon to display the swipe area. It only needs a light brush, it can be said that it is simple to the extreme.

Some people may worry that after the card is lost, it will be opened by the outsider and open the door of the house. If you can register the card, you can delete the card. Just delete the fingerprint and enter the ID number.

If your family has a large population and you like the simple and efficient way to open the door, what should I do if the bonus card is not enough? Don't worry, Chint Intelligent Lock also supports the registration and use of the traffic card. Yes, you are not mistaken. It is the transportation card that you use to take the subway to and from work. You can also turn into a key to open the door. Is it a surprise? Is it unexpected?

Before the mushroom was lucky, I got a brush bracelet. The built-in traffic card features also added a feature to the bracelet. All cards need to be registered before they become a key, and can be deleted at any time, so you don't have to worry about security. Is this a brushed advertisement? Mushrooms help me to contact the manufacturer to discuss the advertising costs.

The three main ways to open the door have already been explained. Then, the combination of door opening method, password plus card and password plus fingerprint, double authentication, double security, you are responsible for the password, I am responsible for swiping the card, usually a small couple can also borrow a door The lock adds some fun to life. Chint, this can be a selling point for you, remember to pay me a fee.

In actual use, it is recommended to activate the smart lock with the card first, and then enter the password to open the door, which is more convenient than using the password first and then using the card.

So many ways to unlock the lock have been explained and demonstrated again, you should have a more detailed understanding of this product, as an electronic product, when the power is insufficient or exhausted, what should I do? Once the power is lower than 4. 6V, the smart lock will issue an alarm, the user can view it in the mobile phone APP, and replace the battery in time, and when the battery is completely out of power, Chint provides two solutions for this, the first is to use the mechanical key The second step is to open the door with an external power supply. There are two metal contacts on the bottom of the smart lock. The 9V battery, which may not be so common, can be used to open the door lock normally.

This kind of battery is not common in households. Personally, you can prepare a battery in the water meter box in the corridor or in the corner of any corner to prepare for the occasion.

If the above evaluation content is theoretical, then the next step is to enter the actual war. As the saying goes, the fingerprint lock that can not be attached to the door is not a good smart lock. This product of Zhengtai can adapt to 99% of the market. The security door, but unfortunately, I belong to the only remaining 1%. This is no stranger to the manufacturers, only to blame my home's door is too strange, it can be said that there is no smart lock on the market can be installed on this door. Everyone remembers, buy a door later, don't buy Wang Li special lock, remember, remember.

However, I am not a person who quits giving up. Fortunately, the door of Laozhang’s family is still a regular model. Although it has been for some years, it does not affect the installation of Zhengtai smart lock. I will not take the picture for the specific disassembly. The process is still relatively Simple, if you are really uncertain, you can contact Chint to install it for free.

He spoke and wrote a report of more than 5,000 words. He thought that he had written the written ones, and finally summarized this product.

The appearance is atmospheric, the workmanship is excellent, and the interchangeable design inside and outside is convenient for consumers to use. According to the convenience degree of unlocking, fingerprint>card>password>key. But according to the response speed, the card is definitely the first. How to choose depends on your personal needs. For double-opening users, Chint can consider launching a fake lock body. After all, the consistency is more harmonious.
