Smart lock, you don’t need to bring a key when you go out, and you don’t have to worry about forgetting the key. It has basically become a standard feature for new home decoration.

However, the fingerprint locks on the market now are not only There are so many styles and brands, and the concepts and promotions are simply dazzling. As a result, we have a lot of unknown knowledge when choosing smart locks. Either we buy them and find them difficult to use, or we spend a lot of money to buy a bunch of functions that we don’t use at all.

Based on this, in this issue, I will analyze it from a relatively professional perspective based on the structure, function, security level, etc. of common smart locks on the market, and tell you which types of smart locks are not recommended to buy, and which ones are necessary What is the function? For your reference!

1. Do not select optical fingerprint

Smart locks are equipped with unlocking methods such as fingerprints, passwords, sensor tags, spare keys, face recognition, etc. Among this series of unlocking methods, only fingerprints may be stolen. Therefore, fingerprintsThe identification method must be accurate enough to be safe.

In this case, what are the fingerprint identification methods? ? Which one is safer?

There are currently on the marketSemiconductor biometric fingerprintandOptical fingerprintTwo fingerprint authentication unlocking methods.

Although there are fewer optical fingerprints, in addition to There are still mainstream brands that make them, so I still have to talk about them. It uses the different light reflections of the ridges and bones of the fingerprint to form images, that is to say, as long as the fingerprint If the texture is clear and correct, it can be recognized.

Theoretically, no one owns your fingerprints, but in reality, the fingerprints pressed on the contract, the cover, and asking colleagues to help check in the fingerprint film purchased online. These lines are clear and consistent. Once someone does something wrong, Fingerprint theft has become the most worrying thing for the elderly. Because it does not require a living body, it is not safe.

AndSemiconductor biometric fingerprint, only recognizes living fingerprints, high security, except If someone takes your finger away, the risk of being stolen is almost zero, which is why 99% of smart locks from regular channels have been upgraded to semiconductor biometrics.

So, after you understand these contents, when buying a smart lock, you only need to ask. If it is an optical fingerprint, just skip it.

2. Do not choose the real ferrule

The so-called difference between real and fake mortices is that after the panel of the smart lock is removed, what is exposed is a complete mechanical lock, which is a real mortise. A lock cylinder is a fake insert

Generally speaking, we think that a complete lock must be more secure than a lock cylinder. Therefore, many merchants show their real inserts when promoting safety, because only you think it is safer. , you will pay.

However, ignoring the actual situation, it is not easy for thieves to destroy the panel in a short time. If a difficult panel can be destroyed, how much effort will it take to destroy another lock cylinder?

Moreover, in terms of the location of the real and fake ferrules, the keyhole of the real ferrule is generally in the middle of the panel, while the lockhole of the fake ferrule is below or on the side. It is inconvenient for tools to reach in and it is more difficult to pry. .

So, Real ferrules are more gimmick than practical, there is no need to worry about ferrules, and there is no need to increase the budget for real ferrules.

3. Do not choose a handle-type smart lock

If you choose a handle-type smart lock, your door-opening process will be: fingerprint recognition → manually turn the handle → the door opens, and the closing process is: open the door → press the anti-cat-eye switch → close the door.

In addition to the semi-automatic door opening method, closing the door also requires an extra step. Imagine forgetting the key, let alone pressing the cat eye switch?The operation is really troublesome, it is not recommended to choose it.

It is more recommended to choose a push-pull smart door lock, are generally fully automatic and automatically lock when closing the door. There is no need to prevent cat eyes, and there is no need to pull the handle to confirm whether the door is locked. The operation is simpler, faster and more convenient.

Push-pull smart door lockAlthough it is more convenient, it is alsoThere are two technical paths: built-in motor and rear clutch, the former is silent It has better performance, unlocks quickly, and is more advanced without manual locking.

As for the latter, although the rear clutch is fully automatic, unlocking is divided into two stages, that is, we often hear \”Zizzizi…click (lock cylinder turns – unlocks)\” It will be slower than opening the lock directly with the built-in motor. You also need to click manually to close and reverse the lock. Of course, you can set up automatic locking. The difference between the two is just a few seconds, so you can choose according to your budget.

There is anotherUncommon embedded smart door locks, because it is embedded in the door, it is usually sold together with the door. This high-end combination is bound to be much higher than the budget of the door + smart lock. Suitable for families with a higher budget, since you are a wealthy person, give priority to smart locks with built-in motors for a better experience.

4. Do not choose door locks with low fingerprint recognition rates

In fact, when choosing a smart lock, there is another very important indicator that directly affects the user experience, and that is the \”fingerprint recognition rate\”.

Each company claims 98% , 99% recognition rate, but this is not actually the case. If it can reach 90%, it is already considered very good.

That How to specifically identify?

Adult fingerprints are relatively Complete, but the fingerprints of the elderly are worn and peeled off, and the fingerprints of children are relatively shallow. When we choose smart door locks, You can bring the elderly and children for on-site testing,If a smart lock can be opened successfully after several attempts, the recognition rate will definitely be fine.

Furthermore, try not to choose hidden fingerprints For the smart lock designed, because the identification hole is at the back, your finger cannot accurately align with the identification hole at one time, which will definitely affect the recognition rate.

5. Do not choose a variety of smart designs

When it comes to the functional design of smart locks, some of the various functions are really not useful. For example, if you threaten to call the police, the sound of the door alarm can attract the attention of neighbors.

Also, pedestrian detection video, record They are all neighbors; with remote authorization passwords, it doesn\’t matter if someone you really trust tells you the password, but if you don\’t trust someone, you can\’t trust them to enter your home.

Furthermore, App functions, real-time pictures, doorbell reminders, language unlocking, etc. are not necessary,What is really necessary are low battery reminders, trial and error alarms, anti-pry alarms, electronic peepholes, etc.These are what are needed to improve convenience and practicality.

In addition, if there is a reminder when the door is not closed, or if you can use facial recognition to unlock the door when your finger is accidentally scratched, it will be a bonus.

Therefore, within the budget, first select necessary items and bonus items. Unnecessary items can be given as gifts, but you must not pay IQ tax to increase the budget for them.

6. Do not select Class A lock

One ​​of the most important indicators to measure the security of a smart lock is the security level of the lock cylinder.

The safety level of the lock cylinder is divided into three levels: A, B, and C. The internal structure of the A-level lock cylinder is simple, and the technical opening time is 1 minute; the manufacturing accuracy of the B-level lock cylinder is higher than that of A, and the technical opening time is 1 minute. The opening time is 5 minutes; and the C-level lock cylinder is currently the most secure lock cylinder, and it will take a thief 10 minutes or more to open it.

Obviously, you cannot choose a grade A lock cylinder. It takes a minute to pry it open, which is too unsafe.

Write at the end

Many people are worried about the small black box interfering with unlocking. That was 19 years ago. At that time, smart lock technology was still relatively immature, and there were technical security risks. Now, technology is developing, and regulatory authorities are also Upon inspection, these vulnerabilities no longer exist

AlsoAs for the so-called battery life issue, smart locks with built-in motors consume the most power, but they can be used for at least half a year, and others can be used for 1-2 years, so there is nothing to worry about.

As for the choice of brand, the simplest and crudest one is The method is to choose a brand that everyone has heard of, formal channels, and authoritative third-party testing reports, at least you will not fall into the trap.

Last and last, no matter the mechanical lock is still Smart locks, as long as they are locks, are resistant to gentlemen and even more so to villains!
