Foreword: end the key trouble

The past two years seem to be the spring of the rapid development of household smart locks. The neighborhood where I live and nearby communities can see the figure of smart lock promoters from time to time, and the neighbors opposite the door are also equipped with smart locks. Strangely, I can occasionally hear colleagues talking about smart locks. Two years ago, even earlier, I didn't realize that there was such a thing as "smart locks", Although I used a lock that only needs a card to open the door when I went to a hotel to open a room, it will never be associated with the smart lock, let alone the degree that the smart lock can be landed at home.

As a technology enthusiast, how can you not try it? Since the popularity of smart phones has made me feel the beauty of technology changing with each passing day, I have always been willing to embrace new things in a more open manner with a little trust and an active attitude of trying for every technological progress. Especially for people like me who often forget to bring keys, I have long wanted to use smart locks to end the troubles brought by keys.

Home smart locks are not managed 24 hours a day like hotel locks. In addition, the home has more daily possessions and is a haven for family happiness. The security and privacy requirements are far higher than those of hotels, apartments and other occasions. Therefore, the selection of home smart locks must be careful. For this reason, I have collected a lot of information about smart locks to make up for it.

Dry goods: choose smart locks rationally

In my understanding of "intelligence", strictly speaking, "smart lock" is more appropriate to be called "fingerprint lock" or "password lock", because most of the locks on the market are called "smart locks", and the main unlocking methods are fingerprint, password, card and spare key. To achieve mobile phone interconnection, you need to choose a gateway or have no choice at all, In addition, the operation of the smart lock adaptation gateway is not friendly and seems tedious. Its functions are basically limited to real-time dynamic door lock reminder. At most, temporary door opening password authorization is still a way to go with the ideal "smart lock", which is also called "smart lock".

When choosing an intelligent lock, security is always the first consideration.

The main stressed panel is also made of plastic, and the Samsung smart lock, whose price is impressive, is not considered first. Most locks are made of zinc alloy panels with the best fit between molding and firmness. In terms of physical damage such as fire protection and riot prevention, metal panels have better bearing capacity than plastic panels.

The most commonly used unlocking method of the smart lock is fingerprint or password. According to the price of a certain treasure, according to the rough score, most of the smart locks on the market below 2000 currently use optical fingerprint identification, that is, the fingerprint identification technology commonly used by the attendance machine with green light or red light.

More than 2000 years ago, semiconductor fingerprint identification is used, usually with faint blue light, and no light source is emitted at the bottom of the identification area. At present, the most famous semiconductor supplier is FPC of Sweden. It is said that this live fingerprint identification technology can directly reach the dermis identification, effectively preventing fingerprint replication from starting.

Of course, except for extreme cases where you need to use high-tech to copy your fingerprints, it is rare for fingerprints to be copied.

When using a password to unlock, we will inevitably think of the embarrassment of using a password to unlock in front of relatives and friends, and we are afraid that people with ulterior motives will covet it. Therefore, when choosing an intelligent lock, we must consider the function of a virtual password with a peep proof function. The so-called virtual password is a blind unlocking method that can add random numbers before and after the real password to cover up the real password.

According to the regulations, intelligent locks sold in mainland China must be equipped with emergency keyholes in case of emergencies such as fire fighting and power failure. Although the mechanical keyholes of intelligent locks are relatively hidden, they have the same risk of being opened by technology as mechanical locks. However, according to the manufacturer's publicity, most intelligent locks use the highest anti-theft standard C-level lock cylinder, that is, the super B-level lock cylinder.

So how to divide the anti-theft standard? According to the classification of GAT73-94 Mechanical Anti theft Lock issued by the Ministry of Public Security, the lock cylinder with ordinary protection level is indicated by the letter "A", and the lock cylinder with advanced protection level is indicated by the letter "B". The technical opening time of Class A lock cylinder prevention shall not be less than 1 minute, and the destructive opening time shall not be less than 15 minutes. Common word lock, cross lock and crescent lock; The technical opening time of Level B lock cylinder prevention shall not be less than 5 minutes, and the destructive opening time shall not be less than 30 minutes. It is commonly a double row lock with curve.

Class C lock cylinder is the enterprise standard, and the standard is that the technical opening time is not less than 270 minutes, and the destructive opening time is not less than 30 minutes. In view of the lag of the release of the national standard, the Class C lock cylinder is more secure than the national standard. The common key of Class C lock cylinder is snake shaped wiring. The long technical opening time of the C-level lock cylinder is far beyond the psychological expectation of the thief, which is enough to deter criminals.

After considering the security, it is the appearance of the smart lock.

The so-called "beauty is justice", a smart lock that will take five or six years or even longer to get along with you day and night, has to be cared about by beauty.

Personally, I think that too many textures, exaggerated shapes or sultry colors need to be matched with the corresponding home decoration style to avoid being abrupt. At the same time, I may feel that this style of smart lock is fresh and avant-garde at that time, but times have changed. Once popular, it will appear different and produce aesthetic fatigue, so I am not easily outdated because of the passage of time, After repeated comparison and selection, the intelligent lock with minimalist design style that can match different home decoration styles was finally selected as Indiron intelligent lock dry steel S2.

Unpacking: see the quality in detail

get down to business.

When unpacking the express package, one is the smart lock packaging box, the other is the gateway packaging box. The packaging is simple and elegant, or the kraft paper material, which conveys the quality of the product very well.

The packaging box of Indiron Smart Lock is designed so that it does not need to tear and tear the sealing glue like other packaging boxes. As long as it is folded and perforated, the box can be easily opened.

Hold the box in your hand and shake it. There is no sense of looseness inside. When you open the box, it turns out that each part is fixed in the customized foam board.

There are protective sleeves on the internal and external lock panels. When you remove the protective sleeves and grab the panel, you can't help sighing: "This lock is polished so delicately!"

In order to ensure that the emergency spare key is not used by others, the key box is sealed in a one-off package. The key box must be destroyed before the key can be taken out.

Next, let's take a look at the "family photo" of the main accessory of the Indiron intelligent lock.

Full list:

Most of the electronic products we have contacted before are "flat to the end", even a little rough, perhaps because people basically do not look at the inside, and it is easy to perfunctory, but the inside panel of the Indiron Smart Lock has fine horizontal and vertical right and wrong lines, and every place can feel the manufacturer's intention.

It should be pointed out that due to the use of electroplating and wire drawing processes, the photos of the Indiron Smart Lock Dry Steel S2 Red Ancient Copper Lock are somewhat different from the actual color. However, I think the actual color of the dry steel S2 is more consistent with the true color of copper.

The whole body of dry steel S2 adopts geometric lines to construct the shape, with clear and neat edge turns, simple, bright and refreshing design language, and large area of zinc alloy metal panel, which makes the overall appearance more thick and firm. With the help of polishing, electroplating, wire drawing and other processes, the corners are hard and touch delicate, not sharp, and the color is simple, natural, but not rigid, The bright ABS plate inlaid on the handle and the bright silver ring set on the handle are refreshing and colorful for the lock.

In order not to expose the fingerprint head and password screen directly and attract attention, but also to keep the screen and fingerprint head clean for a long time, as well as the aesthetic demands of life of integrating locks, I chose the slide type dry steel S2. Admittedly, the price of straight fingerprint locks is generally low. It seems that straight fingerprint locks are the low configuration of smart locks. In practice, the damping cover of the sliding cover is pushed and pulled up and down just right, which is effortless, and there is no sense of looseness or faltering.

The large-area password touch screen of Gangang S2 has brought me an amazing experience like a smart phone screen, especially after the lock is installed and the screen is lit, compared with those smart locks that are still using keys to enter passwords, I don't know how many times fashionable, elegant and technological.

The bottom of the outer panel is the emergency lock hole and emergency power interface.

The upper part of the inner panel is a battery slot, which can accommodate eight No. 5 batteries. There is a safety knob below. After the knob is locked, the independent safety tongue is locked, and the ordinary unlocking method cannot be opened. It can only be opened after the knob is reset to ensure the privacy of personal life.

The lock body is the central role of the intelligent lock, which is equivalent to the city to the city gate. It is not only the only way to get in and out of the city, but also a solid barrier to prevent foreign aggression. Therefore, the lock body must be solid.

Guan claimed that the lock tongue of the Indiron intelligent lock body is made of precision cast 304 stainless steel, which is a material commonly used on hot water bottles. It is said that this material is higher than the hardness of 55HRC of ordinary saw blades and can prevent sawing. The locking tongue has a conventional anti tangent mute tongue, an anti locking tongue and an independent safety tongue. The upper and lower sides of the lock body are equipped with anti-theft heaven and earth hooks, which is larger and more complex than the previous mechanical lock.

Installation: sincerely praise the lock installer

Installing an intelligent lock takes more time than installing a mechanical lock. It took nearly four hours in the afternoon to get it installed after making an appointment with a master.

When changing the lock, adjust the opening for the door. At this time, the opening drawing provided by the manufacturer will play a role. The installation master only needs to compare the opening position on the door and draw the outline with a pencil, then he can safely cut and drill.

The weather was hot. It was hard to sweat when the master opened and installed. I hurried downstairs to buy two cans of Red Bull for the master to quench my thirst. After the smart lock is installed, the master takes the initiative to clean the floor, add garbage into the shopping bag and take it away, hoping to give the master five star praise!

The installation process will not be PO drawings, but take pictures of the installed door locks for everyone to feel.

Experience: more than a little thoughtful consideration

By default, there is a voice prompt for each step of operation in Dry Steel S2, which is a more practical and effective auxiliary function. If you feel that the voice prompt is noisy, you can enter the management background and close it.

When the administrator is not set, the factory unlock password is 123456, and any fingerprint can be unlocked. Of course, this lock will remind you of "administrator fingerprint is not set" on the screen with voice every time you unlock it until it is set.

All settings need to enter the administrator mode by pressing the hidden reset key (SET) near the inner panel and battery slot. The Indiron Smart Lock can be set with three administrators, and it is said that up to 200 groups of independent unlocking information can be received and distributed.

The administrator can enter the Indiron smart lock management background, set the unlock password, authorize the MFE card, even set a temporary unlock password with time limit, and view the details of recent unlock information to facilitate information management. In addition, only administrators have permission to enter/delete unlocking information of other members.

After the administrator has set and confirmed the unlock password, you can experience the virtual password. After five or six times of boring repeated input, the conclusion is reached that you can unlock the password, add any random number before the unlock password, add any random number after the unlock password, and add any random number before and after the unlock password. Of course, the length of the input number is limited, but when you input about 12 digits each time, Without touching the top, the number of digits is unknown.

As for the spare key and MFE card, they are basically not used. They are kept at their parents' home and a spare key is hidden in the car for emergencies. When I first used the smart lock, I was not used to it. Every time I went out, I used to bring my keys and touch my pockets. After a long time, I got used to carrying my mobile phone and going out.

Gateway: for the political correctness of "intelligence"

There is no Internet of Things transmission technology to open up the "Ren Du Two Pulse" smart lock for mobile phone and lock interaction. It is difficult to connect with "intelligence" only by fingerprint or password, which is a pre-existing technology. Therefore, most smart locks can be realized by adding smart gateways. Although smart locks are somewhat crude in terms of "intelligence", there are still many places far from my ideal appearance, But after all, it is the most solid step out of home intellectualization.

Like the IoT protocol used by smart home products represented by Xiaomi, the Indiron smart lock also uses the most mainstream ZigBee protocol, which is a short distance, low-power information transmission mode with very stable channel performance.

When it comes to smart gateways, I would like to say that technology should be people-oriented, and smart locks should achieve "intelligence", which requires additional requirements such as gateways, self wiring, and maintaining WiFi signal connection at all times. The operation is relatively cumbersome, especially when matching the information between the gateway and the smart lock, it is necessary to press and hold the reset key of the smart lock and the reset key of the gateway at the same time. Which link is not handled well, It may fail to match, sometimes very annoying. The "intelligence" of my ideal smart lock, even the "lock", should be the self explanatory design logic, which can even make all instructions appear redundant, without too many steps, just like eating and drinking water, it is natural to understand what you want and use it immediately. However, all smart home products have not developed to this stage, Smart locks should not be too demanding.

After the gateway is matched, it is necessary to download the Zhijia 365 APP on the mobile phone. Its operation process and main function display will not be described in detail. The main functions achieved at present have been outlined at the beginning of the article. Here we borrow the GIF map of the Indiron smart lock gateway produced by others to let everyone have a three-dimensional understanding.

After the gateway is adapted, as long as you connect to the network, your mobile phone can receive the use of the door lock at home in real time no matter where you are. Everything in the home is under control, which makes me feel more secure. Especially for those families with a nanny or a couple who have to work and need to know the situation of their children and home at any time, it will reassure you.

Tail: let intelligence be responsible for the "muddle along" in front of us

Before going out, you had to bring a "three piece set" - a wallet, a key and a mobile phone. Now how many people still carry a bulging wallet? Whether you are going to the mall or eating a roadside stall, mobile payment can quickly complete transactions by scanning a code. A few years ago, this was a very strange thing. But in the natural and silent changes, mobile payment has become a part of our daily life, but the wallet has become strange.

The charm of science and technology is to constantly solve the pain points in our life, so that we, who have been used to it, can feel the beauty of science and technology in every progress. After using the smart lock, the key has begun to fade away in my life. I don't need to be as mad and upset as before about the old problem of forgetting to bring the key. The "three piece set" has become "one piece set". I think this is what those technology giants often say about "subtracting from life".

Fu Sheng, CEO of Cheetah, said when talking about the mission of smart future, "Let's be responsible for the" muddle along "in front of us. You just go to the" poem "and" far away ". This is also my expectation for smart locks and other smart products, and I am happy to see it come true.
