After replacing 10 smart locks, I realized: 5 types of smart locks are too difficult to use if \”don\’t ask for them for free\”

I don’t want it for free!

Due to work reasons (home appliance evaluation), my family has replaced at least 10 smart locks in the past 5 years, and it has almost been replaced by the anti-theft door of my home. The hole for the lock was punched through. After using locks a lot, I gained some experience:

Below These 5 types of smart locks belong to the \”IQ tax\” in smart locks – don\’t buy them, they are difficult to use!

.01Handle type

The styles of smart locks can be divided into two types: handle type smart locks, and It\’s called \”semi-automatic smart lock\”; fully automatic smart lock. From the appearance, you can clearly tell ▽

Both The biggest difference is\”Can it be locked automatically?\”: The fully automatic smart lock will automatically lock after closing the door. The handle-type smart lock needs to lift the handle to lock after closing the door.

Isn’t it just for convenience to use smart locks? This action of lifting is really redundant, and there is a risk of forgetting to lock it.

What’s more important is: the handle smart lock is not cheaper than the fully automatic smart lock! You said spending the same money, why not buy a more convenient, worry-free and safer lock?

.02Dry batteries

Most smart locks contain rechargeable batteries. When buying, you should also pay attention to: some The battery of the smart lock cannot be removed. When you want to charge, you need to pull a long charging cable to the door..

Although a two- to three-meter-long charging cable is included, a cable that long is It\’s quite troublesome and might trip people up. It is better to buy one with a removable battery. If the battery breaks down in the future, you can buy it separately, which is more practical than a built-in battery.

But compared to the built-in battery, there is a smart lock that is less practical:

It has no battery at all, you need to buy AA batteries by yourself. The AA battery has less power, so it basically needs to be replaced once every month or two, with 6 to 10 cells needed at a time. Not only is it troublesome, but it also costs money, and it’s really painful to use.

.03Heaven and Earth Hook

Many anti-theft doors are equipped with sky and ground hooks, which are the lock tongues that can stick out on the top, bottom and sides of the door▽

Most smart locks cannot connect to the heaven and earth hooks. When installing the smart lock, you need to discard both the sky and earth hooks(they will not be able to be extended in the future) Now, the sky and earth hooks have completely become decorations) In fact, it doesn\’t matter. The sky and earth hooks just look spectacular, but they are not safer.

But some users are reluctant to abandon the sky and earth hooks. You will choose a smart lock that can connect to the sky and earth hook:

You will regret it after installing this kind of lock for half a month – it is very laborious to open and close the top and bottom hooks, and it is a waste of electricity to put it on the smart lock. Originally, it only needs to be charged once every six months. The heaven and earth hook may not be used for half a month.

.04With camera but no internal screen

Many smart locks now have door locks The camera is actually very convenient: you can observe the situation outside the door in real time. And it’s still rolling in. The clarity of the camera is getting higher and higher, the angle is getting wider and wider, and the night vision capability is getting stronger and stronger.

But smart locks with cameras are definitely more expensive than ones without cameras.

Everyone can understand this, but what I can’t understand is that some smart locks only have cameras outside the door, but no display inside the door. If you want to see what’s going on outside the door, you need to use your mobile phone to connect:

Everyone who has used smart home products knows that the connection speed of mobile phones to smart homes is very slow and often drops out. Originally, with a camera installed outside the door, smart door locks can replace electronic peepholes. Kemen There is no display inside, so someone has to turn on their phone and wait for two minutes when they ring the doorbell——When I saw the situation outside the door, the daylily was cold. The money for the camera was really wasted.

.05Glass panel

I often see similar descriptions in suspense novels: a bad guy steals the unlocking password through the fingerprint on the smart lock combination disk. When I saw this description, I confirmed that this lock must be. It\’s a glass panel.

Because there is only glass The panel will leave fingerprints:

Many locks now have brushed panels, and there are no fingerprints on the surface. Smart locks that cost a few hundred yuan are also made of PP, which is very similar to tempered glass and is also not easy to retain fingerprints.

Leaving fingerprints is not only dangerous, but also ugly!

In addition, glass panels are easy to Scratched. It’s okay to scratch the ugly spots, but the key is that it will affect the accuracy of the keys. I used a smart lock with a glass panel, but after a while the password disk was completely broken. Often garbled characters:

For example, if I press \”5\”, \”2,4,6\” on the password disk will also be recognized at the same time. I often can\’t open the door with the password. I don\’t know if the bad guys can be locked. Anyway, I often lock myself out.
