According to the survey data, the penetration rate of smart locks in Europe and the United States has exceeded 50%, and the penetration rate of Japan and South Korea has exceeded 70%, while the penetration rate in China is less than 3%. Compared with the red sea market where the mobile phone is gradually clear, smart door locks still have great potential in China.
Advantages Technology Smart Lock E1
Mobile phones meet the needs of people's mobile communications, while smart door locks enhance the home security experience, just as needed. These two points must be the reason why Liu Jiangfeng is involved in this field.
In fact, the entry of superior technology is not too early. Traditional home appliance manufacturers Samsung and Haier have already launched smart door lock products; Xiaomi's Mi family has also launched the Luke smart lock; traditional home improvement brands have also placed similar products into the building materials market.
Back to the topic, on the merits of this E1 product, compared to the brands mentioned above, the advantages of the release of the door locks have any advantages?
Appearance
E1 front
At first glance, the smart lock of Advantage Technology is similar to Samsung's product structure.
From the top to the bottom, the slide display and the fingerprint reader are respectively, the middle is the password button and the magnetic card sensing area, the bottom is the door handle, and the bottom is also the key hole and the emergency charging interface.
Fingerprint recognition sensor
Inside the slider on the top is a monochrome LED display that shows some unlocking, battery level and so on. The fingerprint recognition sensor on the right side uses a push-pull sensor commonly used on smartphones.
Capacitively, there is essentially no requirement for temperature and humidity compared to lower cost optical fingerprint modules. The former is basically unable to work normally when the weather is cold in winter.
Hidden number button
Below the slider is a hidden light touch digital button for password unlocking. In addition, it is also the sensing area of ​​NFC. In theory, magnetic cards and devices that support NFC can be used together.
Door handle
Below is the same door handle as Samsung, the appearance looks very different from the traditional anti-theft door handle, in fact, just to achieve the push-pull door, there is no meaning.
E1 back
The structure of the back is from the top to the bottom of the battery box, internal lock, anti-cat eye theft and handle.
Battery compartment and Zigbee module interface
The official gave the layout of 8 No. 5 batteries, but in fact, 4 sections can drive the normal operation of the entire lock. Under normal circumstances, 8 batteries can be used for about 15 months.
It is worth noting that the battery box contains a series of interfaces, which are reserved for the installation of the Zigbee/NBIot module. The main function is to support the phone text message alarm when the door lock is abnormal. It is worth noting that the Zigbee module is an optional accessory and costs 299 yuan.
Internal lock and anti-cat eye switch
The Close button below, press once to lock the door, double click to open the door, long press to unlock. The left and right buttons below are the anti-cat eye theft switch.
E1 is made of zinc alloy and is available in gold, silver and copper. The entire lock body is more than 8 kilograms in weight, and the work and materials used for the products below 2,000 yuan are solid.
In addition, according to the thickness of the security door, the official website gives three options of 38?60mm, 60?90mm, 90?120mm, and the way of opening the door inside and outside. Before you place an order, you need to find out which kind of situation your home door belongs to. Otherwise, you may have to buy it and you still have to return it.
Unexpected unlocking methods are available
Advantage App
As a smart door lock, the advantage E1 almost gives you all the unlocking methods currently available on the market, including fingerprints, passwords, APP, NFC and key unlocking.
Advantage App Matching Process
First of all, you need to scan the QR code in the manual to download the companion mobile app. Currently, it supports iOS and Android dual platforms. According to the prompt, you can bind the door lock. Whether it is the addition of fingerprint, digital password or password writing of NFC device, it must be set with the cooperation of mobile phone App.
After binding, you can see all the functions, including password, fingerprint, NFC magnetic card, NFC bracelet, temporary password settings, as well as administrator authorization, door lock recent events, device information, and function settings. The app itself is connected to the door lock via Bluetooth.
Advantage App password settings
In the password setting, a 6-12 digit password is supported. You can also set the age of the password, the period and number of times it can be used. The so-called cycle function can set a special password for the cleaning staff at home, and she can only enter and exit during a fixed period of time on a fixed date.
Advantage App Fingerprint Add
The fingerprint of the lock body needs to be matched with the App to enter the smart lock. The fingerprint information will be stored in the lock itself, and will not be uploaded to the mobile phone. It can support up to 100 fingerprints. Even for small startups, a door lock can meet the demand.
NFC card binding
Card management, that is, the use of locks to write supporting information to the magnetic card, also supports card aging, cycle and limit, the official will be equipped with two magnetic cards.
Bracelet setting
The bracelet is still unlocked by NFC technology. The official standard comes with a bracelet and also supports step counter data.
Temporary password
In addition, a friend who visits a friend at home can also create a temporary password and send it to him. The number of times the password can be used can be set in the setting.
Door lock event
In the door lock event, each time the door lock is opened and the specific time will be recorded. Unusual locks are also recorded separately in the alarm event. This information is required to synchronize via Bluetooth when the phone is close to the door lock.
More feature settings
In addition, in the door lock setting, you can also choose the use mode (the office mode does not automatically lock when the door is closed), the voice broadcast switch, and so on.
No absolute security lock advantage is no exception
Fingerprint unlock
There is no absolutely secure lock on the market, all that can be done at present is to increase the cost of unlocking. Although E1 provides all the mainstream unlocking methods currently on the market, there is a problem that is quite serious.
First of all, from the hardware structure of the lock, it does not support the heaven and earth hooks like most smart locks on the market. What is the hook of heaven and earth? On the side of the security door, in addition to the windproof lock, there is a row of metal posts, which is the anti-theft lock. In addition to the side of the row, usually the top and bottom of the security door will have a similar structure, this is the heaven and earth hook.
But it was originally an anti-theft steel column that was up and down and left and right. Now there is only one row on the side. Does this not weaken the anti-theft function? Actually not. Now that the door is shackled, there is basically no violent door removal. Suppose this person took a chainsaw and it just happened to be stuffed into the door. The sound of this saw lock was enough to attract the Aunt Sun.
As for why these products do not support the world hook? The main consideration is the product life, because the heaven and earth hooks also need to be driven by the motor inside the lock cylinder. With this function, the safety can not be improved much, but the life of the lock will be greatly reduced.
It is worth noting that since the use of the heaven and earth hooks is not supported, when the smart lock is installed, it is necessary to fix the heaven and earth hooks in the door for a long time, and the fixing must be firm. Otherwise, the fixing device will age one day, and the gravity will let the heaven and earth hooks directly lock. In addition to violently removing the door, even if there is a key, the door lock cannot be opened.
Secondly, some thieves will open the front panel of the anti-theft door lock cylinder, and directly twist the drive shaft through the pliers to unlock. But this way also does not work on E1, because the internal main drive shaft is divided into two, staggered design. A single twist on the outside is impossible to unlock.
Again, it is the button to prevent theft of cat eyes. At present, many people who steal, first break the cat's eye on the door, and then stick into a hooked iron bar. Unlocking is achieved by directly pushing and pulling the internal handle. Turning on the anti-cat eye switch, even if the handle is pushed from the inside, it is impossible to open the door.
Finally, the key of the security door adopts the C-class lock cylinder. Compared with the B-class lock cylinder of the cross-type A-stage and double-row marble slots, the key shape of the C-class lock cylinder is single-sided blade inner milling groove or outer milling groove. The key, this is currently a safer level.
Other unlocking methods other than fingerprints and passwords
To sum up, the way to violently unlock hardware is basically impossible, so what about software?
In software, the security level of the fingerprint has been verified on the current smart phone, and the fingerprint itself is only stored in the lock. The fingerprint is only the fingerprint number, which is like the first one is the thumb, the system number is 1, each time you use your thumb to unlock, the mobile phone will only use the No. 1 fingerprint to unlock, and the specific fingerprint pattern will not be uploaded.
In addition, the response speed and recognition rate of fingerprint recognition are not a problem, and the door lock can be opened even if the skin is still wet and the skin is still wet.
Digital passwords, from 6 to 12 bits, can be designed at will. In order to prevent voyeurism, the product also supports dummy passwords. Simply put, you can freely enter a string of 32 digits, as long as it contains a continuous password, then you can unlock successfully.
Regardless of the fingerprint or the numeric password, multiple errors will be temporarily disabled. At present, these two ways to unlock security are decent, but there are some problems on the NFC magnetic card and bracelet.
At present, most of the keys can be equipped with access cards for the community. The same principle is used for the magnetic card and wristband that comes with the E1. Specifically, a string of passwords is written in your magnetic card, and the lock can be unlocked after the door lock is successfully matched.
The problem is that the cost of copying an NFC card is much simpler than copying a key. Now NFC-enabled mobile phones can read and write NFC gates after root. To say a more extreme example, the door card was swept by someone else's mobile phone, and the signal was transmitted to someone's mobile phone. Going home and copying this signal to another card, your home's door lock is no longer there.
Liu Jiangfeng himself believes that the cost of copying an NFC card is the same as copying a bank card. If someone really wants to specifically steal your home, then he can choose a cheaper way to find a locksmith.
He added that this method is mainly for elderly people with fingerprints who are worn out or children who are not yet fully developed.
Low battery can be charged via the bottom USB
For the door lock battery, when it is lower than “10%â€, the system will automatically prompt that the battery is low and need to be replaced when the lock is unlocked. But if you still haven't changed and the battery is dead, you can also open the door lock directly with the key. In addition, there is a Micro USB interface on the outside of the door lock, which can be plugged into the mobile power supply for temporary use.
