After buying my first smart lock in 2021, the author fell deeply in love with this kind of lock that can be opened through fingerprints, passwords, keys, and visitor keys, both in terms of safety and convenience. It is said that it is much stronger than traditional door locks.

However, in the following two years, the author has used more than 10 smart locks. Among them, there are not only locks that are suitable for me, but also many smart locks that are very unsuitable.

So the author summarized 5 smart locks that are definitely not worth buying. These are the author’s experiences of stepping on pitfalls. I hope they can give you some reference. and warning.

Handle smart lock.

With the popularization of smart locks, the user base has become more and more extensive. Among them, there are some short-sighted small businesses. In order to make high profits and seize market share, they unscrupulously open door locks. Some traditional Chinese cultural elements are added to the lock, the most popular of which is the handle that Chinese people prefer.

Traditional door locks require a key to open, so a key slot design is adopted. After inserting the key into the slot, the door lock can be opened by twisting the key.

The handle design is a palm-like design added above the key slot. The user needs to put his palm on the handle first, and then insert the key into the slot., and finally twist the key to open the door.

But in fact, the market has already There is a ban on this practice, because the steps required to operate the door lock are too cumbersome, making it very inconvenient to use. However, these small businesses do not listen to this advice and still use smart locks for this design. superior.

But this is not because it has the advantage of being easy to be pried by others. In essence, the purpose of the handle design is to prevent bad people from prying the door lock. , so in the minds of Chinese people, this is a very useful design.

But now that technology is so advanced, security measures no longer rely on door locks as before. Many Chinese cities have now popularized electronic monitoring facilities, so with the help of these Equipment that records data will definitely help the security department catch the bad guys.

The smart lock is already a relatively tight-fitting device. Coupled with the anti-peeping design of some corners and corners, there will basically be no bad guys to pry the door, so this is just to increase the difficulty of operation. And the design that exists is not practical at all.

And this design also greatly affects the convenience of the smart lock, because the smart lock itself requires the cat\’s eye to use the camera and display to identify outsiders, but With the addition of handle design, these devices It cannot work normally. You can only remove the peephole, connect the camera with a mobile phone, and then open the display screen to see the visitor\’s situation.

After losing the monitoring function, bad guys can also pick the lock. There will be no burden, so it is better not to install monitoring.

Smart locks using dry batteries.

Due to battery life issues, most smart locks on the market use lithium batteries for power supply, but there are also some manufacturers. Because cadmium batteries are cheap and can reduce production costs, many companies have begun to use dry batteries as smart lock power sources.

But in fact, dry batteries are not only of poor quality, but also have extremely poor battery life. Although they are cheap, their battery life not only requires users to replace batteries frequently, but also causes certain problems if left unused for a long time. The issue of degree of loss will cause great trouble to users.

There are also some businesses thatInitially, disposable lithium batteries were used to power smart locks, just like our common mobile power chargers. Although the quality is not bad, frequent replacement of such batteries not only imposes a certain economic burden on users, but also causes certain pollution to the environment.

The rechargeable lithium battery is both economical and environmentally friendly, and it also avoids the problem of loss caused by not charging for a long time. Therefore, it can be said that it is currently the best and most suitable for smart phones. The type of battery the lock is powered by.

Smart lock that can connect to the sky and earth hooks.

In order to further improve the safety factor, some small businesses have also added a sky-and-ground hook design to their smart locks. This design adds a hook under the inside of the door. Only when the key is inserted and the sky-and-ground hook is opened Switch, this hook can be pulled out from the inside. This design is to prevent the outside from being pulled out from the outside.

On the one hand, this can indeed improve the safety factor, but on the other hand, it also brings great trouble to users, because the overhead hook is also a particularly power-consuming system. If people often come in and out of the home, out, then switching the heaven and earth hook is a very battery-consuming operation.

But if the heaven and earth hook is not turned on, bad guys will take the opportunity to sneak into the house to steal or harm people at home. This is very dangerous and irresponsible, so neither of these two problems can be taken into account at all. A good way is to release useless designs too much.

Smart lock with camera but no internal screen.

In recent years, due to the increasing number of theft cases, many families have begun to consider To improve home security, we finally chose a smart lock with monitoring functions, so these smart locks are equipped with small cameras inside.

But because this product itself cannot accommodate too much There are many things, so businesses can only use small internal screens to display surveillance images. However, this internal screen is often just a small monitor and cannot record the viewing process. Therefore, many users begin to worry about visitors and turn on the alert mode, but because there is no video recording function, they cannot tell whether a bad guy has entered the home.

The lack of recording function means that they cannot take out their mobile phones to watch after the bad guys come in, and can only stay at the door to guard at all times. This not only makes it impossible to live normally, but also affects their work. , so the author believes that such a product has noIt\’s meaningless and can be described as a \”superfluous\” design.

Compared with them, the new ones on the market are strictly speaking very useful. Nowadays, the development of technology has begun to connect the user’s mobile phone with the smart cat eye. As long as the user hears the sound of opening the door, he will take a look. The display screen can determine the identity of the visitor. If he is a good person, he will click on the command to open the door. If he is a bad guy, he will not execute the command. This can ensure safety without having to stay at the door to monitor the visitor.

Glass panel smart lock.

Glass is a material we are familiar with. Devices made with it usually have a very modern appearance and are smooth and translucent. It is a material that goes well with home styles. Therefore, glass panel smart locks have gradually become Popular products.

However, the glass panel is actually very easy to retain fingerprints and scratches, which not only affects the appearance, but also affects the user experience. Therefore, the author does not recommend purchasing such a smart lock.

The author shared some types of smart locks that I found particularly difficult to use after using them. I hope it can give you some lessons learned from the past, so as to avoid purchasing these useless wallet wizards that waste space.
