As the smart home industry, smart door locks are now becoming standard small appliances in the home. However, despite the increasing popularity of smart door locks, it is undeniable that there are still many people who are not willing to install them.
For this wave of reluctance to install smart door locks, in fact, the reasons behind it is not difficult to analyze.
① The use of mechanical locks is habitual and does not want to change.
② Worrying about the insecurity of smart door locks.
③ Not willing to spend money to invest (less than a few hundred, more than two or three thousand).
In fact, many people do not know that the domestic smart door locks from the beginning to the development, there have been 30 years of history. From the earliest hotel with a card code lock, to the fingerprint lock in 2000, to today's facial recognition, voice unlocking and other artificial intelligence door locks, the intermediate technology continues to innovate. Especially after the small black box incident in 2018, the market is eliminated clean of poor quality smart locks. So it can be said that the smart door lock ushered in a better space for development.
This issue of the topic, I prepared a full two days(Actually, it didn't take that long.)I hope that through the way of a question and answer, to give you a smart door lock in the end, whether it is safe, worth the investment, I hope to bring you some reference.
A. Intelligent door locks and ordinary mechanical locks, which is more secure?
Locks, in the strictest sense, are used to be opened, so whether it is a smart door lock, or an ordinary mechanical lock, it will be opened. Only the difference between the two is that the open "time" is different.
Just like Andy in "The Shawshank Redemption", no matter how far the prison leads to the outside world, digging through is just a matter of time.
And it is precisely the difference in unlocking time that determines whether the thief will continue to commit the crime. In other words, if you open a lock and spend more than 10 minutes, the mind will most likely collapse, because as long as it is not stupid, you know that the longer it takes to open the lock, the greater the probability of being found.
The key factor in deciding the smart door lock and ordinary mechanical lock unlocking time, does not lie in the smart not smart, but in the "lock core".
To be precise, the premise that the lock cylinder is the same, the security level of both locks is the same.
At present, in the security level of locks, mainly divided into A-class locks, B-class locks and C-class locks. Among them, Class A locks are the easiest to open, while Class C locks are the most secure locks. According to experimental data, the lock cylinder of the C-class locks, theoretically opened for 270 minutes.
So as long as the C-class lock cylinder, rest assured that the smart door lock is as safe(In fact, the smart door locks on the market are all Class C locks).
Second, what are the advantages of smart door locks?
Although in the eyes of the business, smart door locks are blown into a god, hoping to give consumers a concept of "omnipotence". But in the process of my use, I found that its biggest advantage, in fact, is the solution to the trouble.
What troubles are solved?
① Forget to bring the key trouble! (Fingerprint, face, password, APP, bracelet, swipe card ...... can open the lock)
②The trouble of finding keys everywhere! (Carrying a large bag in your hand, find a key or spend half a day, think of all the heart)
③ Worry about the worry of not locking the door! (Fully automatic intelligent door lock, closing the door is locked)
④The trouble of having friends and relatives enter your home after going out! (You can unlock the door remotely, send temporary password, etc.)
For these experiences above, it is really my true feelings over the past year of use. And the people who have used the smart door lock, it is difficult to leave it again, after all, it is too humane than the mechanical lock.
Third, the choice of intelligent door locks need to consider which points?
Smart door lock development for so many years, the market is naturally mixed products, purely from the price, so many people are dazzled. Cheap models have five or six hundred, high-end models are able to reach three or four thousand dollars.
So what core points should we pay attention to when picking a smart door lock? With the conclusion of my research and salesman "indoctrination" explanation, basically can be summarized as the following 4 points.
① Look at the security level
The security level of the smart door lock, the main reference to these indicators.Whether it is a Class C lock core; fingerprint unlocking method preferably finger vein recognition, followed by semiconductor recognition (the latter is the current mainstream identification method); whether the door can be closed and locked; whether there is an anti-cat-eye unlocking function; whether there is a dummy password; whether there is an anti-pry alarm, trial and error alarm.
② see the way to open the lock
Smart door locks currently on the market, there are many ways to open the lock, such as the above-mentioned fingerprint, face, password, APP, bracelet, swipe card and so on.
Although in principle the more ways to unlock the door the better, on the side, more ways to unlock the door also means more possibilities to be opened. In particular, WIFI Smart Unlock, because there are so many loopholes in home interconnection now, so you can choose to close its function.
In fact, I used the smart door lock in a year, found that the most common way to open the lock is mainly fingerprints and passwords, sometimes the elderly to the home will use the card. As for some other locking methods, basically not used.
③ Look at the power supply method
Another point of difference between smart door locks is the difference in power supply. At present, there are two types of mainstream smart door lock power supply, one is a dry battery, which is often referred to as the No. 5 battery. The other is a lithium battery.
Dry batteries can be further divided into 4 and 8, if you choose a dry battery smart door lock, the more batteries, the less frequent the later replacement.
However, from the perspective of environmental protection, dry cell batteries are not as friendly to the environment as lithium batteries.
In addition, in the use of time, most of the lithium battery smart door lock, two or three months to charge once. While the dry battery smart door lock, most can be used for more than six months, or even a year.
In addition to the need to consider the above smart door lock "itself" indicators, in addition to the selection of smart door lock, should also be concerned about the hard conditions of the entry door.
For example, the thickness of the entry door, the direction of opening the door, the height, width and type of the lock panel and whether there is a heaven and earth hook, etc. However, these factors need to be considered, the business will generally be informed in advance.
Written at the end.
Smart door lock is just a lock, but whether it is intelligent and humane, directly related to the happiness of home life. So with the improvement of everyone's standard of living, if not worse for the money, it is best to replace the original mechanical lock. After all, only experienced, you know how practical!
