In fact, the doors of many new houses are of good quality now. There is no need to replace them. Just replace them with smart locks. However, there are so many doors on the market. How should we choose among the types of smart locks?

Today, I will Let’s have a chat at home. When we change the smart lock at home, it is recommended to insist on \”buy 8 and don\’t buy 8\”. This is not nonsense, but the experience and lessons summed up by people who have experienced it. It is really necessary to stick to it.

1. Buy virtual passwords instead of fixed passwords

Smart lock input There are generally two types of password functions: fixed key positions and virtual passwords. A virtual password means that you enter a string of numbers, which only contains your 6-digit or 8-digit password. Compared with a fixed password, its changes are more difficult to predict. Obviously safer.

2. Buy one with Internet rather than one without Internet

Since it is a smart lock, you should actually consider more comprehensive functions. There are many smart locks on the market that are actually semi-smart and do not have functions such as voice linkage or light linkage. Be sure to be optimistic when buying. There is a difference between the two locks. It doesn’t cost much, but the experience of using it is completely different.

3. Buy the door card with encryption or not without encryption

Some smart locks have multiple unlocking methods, one of which is a smart door card. At this time, you must buy an encrypted door card instead of an ordinary door card that can be copied and scanned at will, otherwise it will If someone has bad intentions, it is quite dangerous for the door card to be scanned.

4. The linkage anti-locking function is the icing on the cake

The linkage anti-lock function is the icing on the cake in my opinion. You don’t have to buy this linkage. The anti-locking smart lock is much more convenient to use than the ordinary manual anti-locking smart lock. At the very least, you don’t have to worry about forgetting to lock the door after entering the home.

5. It is best to buy a C-grade lock cylinder and not others

As for the lock cylinder, the AB-level lock cylinder is naturally cheaper, but in terms of safety and anti-prying and anti-opening performance, it has to be a C-level lock cylinder. In addition, we often change the lock without changing the door. Safety needs to be guaranteed. If you have enough budget, it is better to buy a C-level lock cylinder.

6. Don’t buy the additional functions if you need them. Flashy

If the lock has a series of functions such as cat eyes, electronic doorbells, and visitor unlocking, we must remember to consider whether our daily living habits will really be used. These additional features are not necessarily necessary, but they will cost you more to buy the lock. Don’t make random choices just because you’re hot-headed.

7. Buy live recognition rather than optical recognition

In terms of fingerprint unlocking, the anti-theft performance of optical recognition is very low. We have seen unlocking with fingerprint film in some movies, which is basically this identification method. Relatively speaking, semiconductor fingerprint recognition is not There will be a risk of people not using fingerprints to unlock the lock.

8. Try to buy an electromechanical separate lock

Smart locks with mechanical and electrical separation actually have stronger compatibility and stability. Compared with the kind of electromechanical locks with motors built into the lock cylinder, although It is relatively larger, but has higher cost performance, poorer compatibility, and questionable safety.

In short, if your home is also new and you change the door but not the lock, then I really recommend sticking to the \”8 buy, 8 don\’t buy\” when buying a smart lock. I don\’t know what you think. Is that so?
