Smart door locks are eye-catching? Teach you to avoid the pit&; Cost-effective advice

I have written several articles about smart home before, and the response is good. Today, I will talk to you about the first security level of smart home. How to choose a fingerprint lock?

First, the history of the development of smart locks, which kinds have you used?

Smart door locks can be said to be the most popular item in decoration in recent years, especially among young people. But in fact, smart door locks have been in China for almost ten years, but the previous smart door locks were expensive at first, with single function, and even had many flaws in some experiences; Moreover, at that time, people's thoughts were generally conservative, and they felt that fingerprint locks were unsafe, so there were very few families who used smart door locks in the early days.

(Excerpted from the White Paper on the Application and Development of Smart Locks in China 20 17)

Apart from hotel locks and apartment locks, China household smart lock products can be divided into the above five stages.

The initial smart lock, whether it is set up, operated or used, is very complicated. I remember that my uncle used to install a combination lock, which is like this; Because only the digital password can unlock the lock, in order to ensure safety, I will sneak around every six months, find a dead night, watch the complicated instructions in the corridor under the light, and reset the password step by step ... but I have to say that it is much more convenient to enter the password than to bring the key.

Now, the latest smart locks can be seated on the sofa, paired by mobile phones, linked with other security devices at home, and support multiple ways to unlock, such as NFC and facial recognition. It can be said that it is much more convenient.

The most important thing is that the price of fingerprint lock is much lower than before, from luxury to necessity.

Second, the market structure of smart door locks

The entry level of smart door lock is very low, but it is still very difficult to succeed. Although there are thousands of brands on the market now, most of them are OEM, and it is still difficult for ordinary consumers to choose. Mainly divided into three camps, namely,

Traditional door lock brands, such as Yale, Schlage and Goldman;

Internet brands, such as Xiaomi, Kaidishi and Luke.

Cross-border brands, Samsung, Midea, Panasonic, etc.

Brands that do professional door locks generally have better product quality, and most of them have wired stores, which has better pre-sales and after-sales experience; However, the shortcomings are also obvious. The basic model has a single function, and the flagship model has many functions, but the premium is serious.

The advantages of door locks of internet brands are fast technical iteration, diverse functions and more styles than traditional brands; In addition, it has better marketing ability than traditional brands and can spread among young people; The disadvantage is that the quality and after-sales are relatively weak.

Cross-border brands combine the characteristics of traditional door lock brands and internet brands. According to the different capabilities of brands, they will not be launched here.

3. What should consumers pay attention to when choosing smart locks?

1, budget and price

The first consideration is the price. Since the price of smart door locks was beaten down by Internet brands, the prices of most fingerprint locks are concentrated between 1000 yuan and 2,000 yuan. If the price is below 500 yuan, it is generally not credible except that the business sells half and gives half. After all, it's worth it. Later, I will recommend some reliable locks to you according to the price.

I would like to remind you that there are all kinds of new product crowdfunding activities on the Internet. If it is an unknown small brand, it is strongly recommended that you avoid the pit, because the product has not yet been made, and I don't know how it is, let alone word of mouth.

2. Materials

Personally, I think it is best to choose the color of the smart door lock that is consistent with the color of the door body, which has two advantages. First, you can keep the style of home improvement coordinated. Secondly, I think it has a certain security function. What can I say? The door lock is inconspicuous, and the thief cares. If it is a golden door lock, it is estimated that the neighbors will come to visit.

In terms of materials, it should be noted that panels and handles, especially some cheap door locks, look like metal, but they are actually plastic products. If you use it for a long time, it won't look good enough.

3. Quality and after-sales service

Smart door locks are different from mobile phones and headphones. They are fast-moving electronic products that will not be changed after decades of use. First of all, the quality must be reliable. The handle, fingerprint module and appearance material of the door lock must be formally verified. Think about it, if the fingerprint module fails, it is also a bad thing to be locked out. In addition, it is the after-sales problem. If you are unfortunately recruited, there are some minor problems with the smart door lock, there are no after-sales outlets offline, and calling 400 is outsourcing customer service ... then you will regret it.

4. The more functions, the better.

Some brands of smart door locks mainly unlock in various ways, but according to my years of experience in using smart locks, I use fingerprints most, followed by numbers; As for other unlocking methods, such as remote unlocking, face recognition and voice unlocking, they are generally immature. For example, in risk monitoring, a brand's face recognition fingerprint lock was successfully opened through a black-and-white photo of a person from different angles.

5. Recognition accuracy/speed

Whether the smart lock responds sensitively and accurately is also a reference to judge whether a lock is of high quality. Especially for the group whose fingerprints are generally shallow, has the manufacturer adopted a better identification scheme or an alternative scheme?

6. Look at the lock core/lock body

Security, in addition to the lock mode, another need to consider is the lock core.

At present, the commonly used lock cores are Class A, B and C lock cores.

Structurally,

Class a lock cores are mostly flat or crescent-shaped, and most of them have a row of grooves on one or both sides;

Class B lock core, similar in shape to Class A, with two rows of grooves on the surface;

The C-class lock core has two rows of grooves on one side or both sides, which increases the S-type keyway and increases the difficulty of unlocking.

In terms of unlocking time,

For example, class A and B lock cores can be opened by thieves in a few minutes with tools, while class C lock cores need tens of minutes to open;

The mainstream lock bodies are ordinary lock bodies and overlord lock bodies. The common lock body is simply 6068 lock body, where 60 represents the distance from the center point of the lock core hole to the side of the lock body, and 68 refers to the distance from the center point of the square rod (linkage handle) hole to the center point of the lock core hole. Generally, the length of the side bar of the lock body is 240 mm

On this basis, the length of the locking edge strip is increased from 240mm to 388mm, and two locking tongues (also in the form of hook and loop) are added to increase the firmness of the door for locking. Before buying the overlord lock body, please consult the customer service to see if it meets the installation conditions.

Locks are a defense against gentlemen and villains. At present, the lock core of high-quality smart lock runs through the lock body, and even if the panel is damaged by violence, it will not be opened.

7. Circuit design/black box

The design of electronic circuits is a difficult point for ordinary consumers to judge, so the simplest way is to see whether the official introduction or customer service can prevent "black boxes".

The technical term for black box is called Tesla coil. The principle is that by interfering with the internal circuit of the smart door lock, a strong electromagnetic field is generated instantly to open the door lock. At present, the mainstream smart door lock in the industry has solved this problem.

8. Is the connection between heaven and earth useful?

I think the hook looks safe, but it is not recommended by students who install smart locks.

The original intention of the hook between heaven and earth is to increase the number of lock points to prevent the door from being pried open by violence. Most of the domestic burglary cases are technical unlocking. By learning the correct key opening method, the door can be opened.

Another reason is that the smart lock is double-sided, not only to "lock" but also to "get out". The lock tongue of the heaven-earth hook will not only increase the difficulty of breaking it, but also be difficult to take back once it catches fire.

Moreover, the door lock using the heaven-earth hook also needs the motor of the intelligent lock to drive, so it will consume more electricity, thus affecting the life of the lock; Moreover, in addition to the door lock, the safety of the home is also closely related to the public security of the community and the city.

Having said that, I would like to recommend several smart door locks with good market response.

Fourth, smart door lock recommendation

(1) 1000-2000 yuan

Xiao mi mi Jia intelligent door lock

Generally, the products under the banner of "Mijia" are not particularly excellent, at least they will not step on the pit; First of all, the price is not expensive in similar products, but the level of making friends.

Secondly, the design is simple, and the fingerprint module is also placed at the thumb of the handle, which can open the door with one button.

In addition to fingerprint identification, you can also open the door by password, NFC, Bluetooth, mechanical key, mi band, etc.

Don't worry about safety. Class C is directly inserted into the lock core and embedded in the whole lock body, so even if the panel is violently removed by outsiders, the lock core still plays a role.

In addition, there is an anti-cat-eye unlocking button and an anti-lock knob on the inside of the door lock. It is worth noting that the anti-lock can only be turned after being pressed to prevent children from misoperation.

Moreover, this door lock can naturally be connected to Mijia's smart home to achieve more complicated linkage, such as going out to open the security mode and enabling the camera at home; Go home and turn on the porch light, music and so on.

Aqara intelligent door lock n100&; N200

Mijia's eco-chain company, the smart door lock of Xiaomi Mijia is also designed by Aqara, and N 100 and N200 are their dual-platform products, which support Mijia and HomeKit.

First of all, there is no need to worry about security like Mijia smart door lock. It is also equipped with a straight lock body and a C lock core, which is more stable than the "down insertion" structure. Even if the front panel is damaged, it cannot be unlocked by the transmission structure.

Secondly, both types of locks can support seven unlocking methods. Personally, in addition to the convenience of fingerprint unlocking, NFC unlocking is also quite easy to use, which is compatible with Xiaomi mobile phone and bracelet unlocking. Apple users can use HomeKit's Near Field Bluetooth to unlock it.

The recognition success rate and connection speed of the two door locks are at the same level, and the material of N200 is more solid, so the design is getting higher and higher. Students who pursue cost performance can choose N 100, and students who control value can choose N200.

Luke Classic 2S Intelligent Door Lock

Luke belongs to the internet brand and lives well. At present, my family and parents use T1&; Classic2S 1, which has been very stable for several years, belongs to Luke's treasure in the town shop.

Compared with 1 generation classics, Luke Classic2S has been fully upgraded, including adopting a more durable double bearing structure, increasing the number of unlocking methods from 5 to 6, and adding a built-in clutch and a mechanical self-locking lock body, so that users can automatically lock after leaving home, which is suitable for careless users.

The NFC card is added, and the security is good. The double authentication of CA certificate and card private key signature is adopted, the security level is much higher than that of ordinary door magnets, and it is suitable for the elderly and children with blurred fingerprints.

The second advantage is that Luke Classic2S does not need to lock the door manually. The lock will automatically pop up when the user closes the door. I think this function is suitable for my obsessive-compulsive disorder. I remember once traveling abroad for a week, I was in a hurry to catch the plane and didn't lift the door lock. As a result, I always feel that I have something in my heart when I travel, so I check the monitoring from time to time.

In addition, the door lock can also be connected to Mijia like Mijia door lock and Aqara to realize linkage function.

(2)2000-3000 yuan

Deshiman Q5 intelligent door lock

If you don't like the appearance of Mijia, Akara and Luke, you can choose Deshiman Q5, which is also his main style at present.

Q5 put the fingerprint module in the panel, and it is fully automatic. When Q5 successfully recognizes the correct fingerprint, the motor drives the lock cylinder to rotate, the lock tongue will automatically retract and the door will automatically open.

Through the key lock/unlock, there is no handle in the door, which fundamentally eliminates the problem of cat's eyes being stolen.

Deschmann Q5 has a built-in WiFi module, which does not need other gateways to help lock the network.

However, I also want to remind everyone here that the touch unlocking method is more refreshing and labor-saving, but the failure rate will be slightly improved ~

Kaidishi K 1 1 intelligent door lock

K 1 1 is also a fully automatic intelligent lock, a class C lock core. After the fingerprint verification is successful, the lock tongue can be automatically pulled and unlocked.

Similarly, WiFi is directly connected, and the door lock status can be monitored remotely without a gateway.

And the door lock also has a built-in protection function. When it is in danger after opening, it will call the police and push it to the mobile phone.

In addition, the door lock also has a humanized function, with its own intelligent voice, which can be convenient for the elderly or children to use; You can also press and hold the "#" key in the middle of the night to turn on the mute mode to avoid going home late at night to disturb your neighbors or family.

Samsung intelligent door lock DP728

Samsung smart locks have been doing well in traditional brands, and now the price is not as high as before. This DP728 is an upgraded version of the classic DP7 18, which has a good sales volume all over the world.

The appearance continues Samsung's classic push-pull design, and fingerprint recognition is placed on the top alone and needs to be turned over. In addition to fingerprints, you can unlock the car door by Bluetooth, numbers or magnetic cards.

In addition, Samsung can also enable dual authentication, which can only be unlocked if the password+fingerprint is correct.

Moreover, Samsung Lock has a function that I particularly like, that is, when there is a fire, the sensor senses high temperature, and it will automatically give an alarm, open the door lock and let people escape quickly.

Built-in wake-up sensor will open the welcome mode when you are 50cm away from the door, which is very ceremonial ~

The disadvantage is that the networking function of Samsung Lock is slightly poor, so it is necessary to buy an IoT suite to see everyone's acceptance.

(3) more than three thousand yuan

Schlage U830 1 Intelligent Lock

Schlage is a century-old American brand, and the overall quality of its products is obvious to all. This U830 1 is also an explosion in the store. Adopt color matching design, and adopt high-quality zinc alloy metal panel on the front. No matter the panel, handle or lock tongue, it has ultra-high strength and can effectively prevent violent unlocking.

Class C lock core can support password, fingerprint, NFC, Bluetooth and other unlocking methods, and a small screen is designed inside to keep abreast of the lock state.

In terms of personalization, the shell of U830 1 can also be freely matched according to its own home style, such as black and white, oak and black mahogany. Let the lock and the room be more integrated.

GateMan A330 intelligent push-pull fingerprint lock

GateMan, also from South Korea, is also a reliable high-end brand, and A330 is also a popular model of this brand. First of all, the appearance adopts an integrated design, and there is no keyhole and no security loophole.

The touch area adopts high-density surface wire drawing technology, so there is no need to worry about leakage caused by residual fingerprints in daily use.

In addition, GateMan's door lock is a long-life champion, and it is in a deep sleep system every day, and only when it is triggered will the power be turned on. Four batteries can last about 15 months, which is twice as long as many similar products.

Big-name locks may not have so many fancy functions, but they are superior in stability and quality.

Five, choose the quick cheats of door lock.

There are too many smart door locks on the market, so this recommendation can't be comprehensive.

Give you some common reference points,

1, not greedy for cheap, look for the brand;

2. What is the fingerprint recognition rate, especially in families with old people and children; If the fingerprint recognition rate is not good, is there any other reliable alternative?

3. Is there a temporary password for a friend's nanny to enter the house?

4. Is there a stable networking function to facilitate mobile phone reminders?

5, the life of the lock, the frequency of changing the battery;

6, when in danger, can quickly alarm and prompt;

Well, thank you for reading my article. I hope everyone can find a smart door lock that suits their home. Please leave a message if you have any questions, and I will answer them quickly ~
