For security reasons, in the fast-paced modern society, many Chinese families have installed smart door locks, which are convenient, fast and safe.

However, with the passage of time, the smart door locks that were once favored by young people are not easy to sell, why is this?!

Through countless negative reviews from netizens, I finally found the answer, and after reading these, you won't be surprised at all!

(1) Security is not as expected

Ordinary door locks, a door lock can be equipped with several keys, the reproducibility is relatively strong, and it is easy to be entered.

The smart door lock is different, it can achieve the purpose of identification and anti-theft through modern technology.

Therefore, many people choose smart door locks, and even blindly follow the trend of high-end smart door locks in order to improve the anti-theft level.

However, after a deep understanding, I realized that "ordinary smart door locks and high-end smart door locks are all used to achieve the purpose of anti-theft through the lock cylinder." ”

"Compared with ordinary door locks, smart door locks do not provide additional protection, but derive more security problems."

Specific performance:

1. The door lock is out of power, and if you forget to change the battery, you will be locked out of the door.

2. When I woke up, the door opened inexplicably.

3. The fingerprint lock is always inexplicably out of order......

In this way, more and more consumers have lost confidence in smart door locks, so that more people understand what "door locks are not against gentlemen", if thieves have intentions, it is not safe to install smart door locks.

4. Serious functional homogeneity

Ordinary smart door locks have a bad experience?

Salesmen often suggest that we buy higher-end smart door locks, saying that this thing is worth what you pay for, and the expensive one is definitely better than the cheap one, and the experience is better.

But in fact, there is no obvious difference between the two, whether it is the speed of unlocking, stability, function, etc.

For example, they all have basic functions such as fingerprint recognition and password unlocking, and additional functions such as monitoring and voice, but they are all similar to use.

5. High installation and maintenance costs

普通的門鎖，從安裝到維護不過百元。

And buying a smart door lock casually will cost hundreds of dollars, or even thousands of yuan, and it may be more expensive if you pursue appearance and multi-function.

Not only that, in the process of ordinary use, if it is an ordinary door lock and the key is lost, we can directly replace the lock with a new one, just in case.

But if it is a smart door lock, whether it is broken or cracked ......, it requires a large amount of money to maintain or replace.

In short, as an important part of home intelligence, smart door locks provide us with a little convenience, but they are flawed and have many problems.

Personal Advice:

Or don't buy a smart door lock at all!

No matter how rich you are, you must pay attention to these when buying smart door locks!

1. Choose semi-automatic, not fully automatic

The purpose of smart home is to free your hands, many people will choose a fully automatic door lock when choosing a smart door lock, but in fact, although this door lock has many functions, the failure rate is also high, and it is more power-consuming.

The semi-automatic door lock is driven by the clutch, although compared with the fully automatic smart door lock, the function is less and simpler, but it is also relatively more durable and stable, and the failure rate is low.

Therefore, if the purpose of installing a smart door lock is "safe and durable without a key", it is better to try a fully automatic smart door lock.

2. The lock cylinder of the smart door lock must be C-grade

The security of a smart door lock mainly lies in the cylinder.

The higher the level of the lock cylinder, the more reliable, durable and safe.

Class A (B) < Class C

Class C can achieve 280 minutes of pry resistance.

Therefore, when you choose a door lock, you must choose that the lock cylinder is C-grade, and choose the lock body as stainless steel as much as possible, so that it is not easy to rust and will be more economical and durable.

3. To choose the electromechanical separation

Many families choose purely electronic smart door locks.

Because this is more high-end security, but in fact, there are many problems, that is, once the power is out, the smart door lock will lose its effectiveness.

The electromechanical separation of the intelligent door lock, even if the power is out, does not affect the normal door opening, can effectively prevent emergencies, such as avoiding danger in the event of a fire.

4. Buy with a fake password feature

When choosing a smart door lock, because there are elderly people and children at home, many people take into account the basic functions of the door lock, fingerprint recognition, password unlocking, etc., and also take into account various possible accidents, and choose a smart door lock with additional functions such as monitoring and voice.

As everyone knows, the smart door lock with a false password function is also very important, after all, every family may have guests visiting, and it is possible to encounter the situation that the host is not at home and the guest visits, so that if the fixed door lock password is told to the other party, it may cause privacy leakage.

If the smart door lock has a false password function, then when we face strangers, we only need to tell them the temporary password, and we don't need to change the password of the door lock frequently.

There are pros and cons to smart door locks!

While we are eager to let go, we must also understand the hidden shortcomings behind it and measure it clearly, so as not to spend money in vain
