Moreover, thieves are more willing to choose ordinary mechanical door lock . Technical lock unlocking is much simpler than violent lock removal. Who would be willing to make such a big noise to expose themselves?

Anti-theft ability Look at lock core

Whether it is an ordinary mechanical door lock or a smart door lock, anti-theft ability mainly depends on the lock core.

lock core is divided into three levels: A, B, and C. The C-level lock core has the highest safety factor. The commonly used smart lock core of is the C-level lock core . Theoretically, the technical unlocking time is more than 270 minutes, and there are also a variety of intelligent anti-theft and alarm functions.

So you are worried that it is not safe enough, so you are a little worried.

fingerprint copying is not that easy

There was a news some time ago that an older sister went door to door to print fingerprints. Everyone couldn't help but worry, will the fingerprint be copied?

This is what depends on the fingerprint unlocking method .

fingerprint recognition includes recognition module and chip . The identification module collects fingerprints, records and recognizes them. If the fingerprint is wrong, an alarm will be issued.

Currently, there are three ways to unlock the smart lock fingerprint recognition.

Optical fingerprint recognition is not safe. , like our commonly used punch-in machine, records the surface texture of the fingerprint and is easily copied.

semiconductor fingerprint recognition is more mature , recording fingerprints through temperature, pressure, electric field and other aspects. It is the same as unlocking a mobile phone fingerprint, with a high safety factor.

Among them, Swedish 's FPC is a high-end semiconductor recognition chip , comparable to Huawei in the mobile phone industry. Kaidishi and Siemens are used; Samsung chips are produced and sold by themselves; Xiaomi Precise is an emerging small-scale high-quality enterprise.

finger vein unlocking is the new star of fingerprint recognition , which records and recognizes changes in finger veins. For shallow fingerprints and broken fingerprints, the recognition rate is higher , and the safety factor is also higher, but because of the high cost and expensive products, it is not popular yet, which is very worth looking forward to.

Note that the fingerprint algorithm of smart lock determines its security status. The faster the chip computing speed, the better. Many low-end smart locks reduce the algorithm in order to improve the fingerprint recognition speed, but instead reduce the security.

Purchase smart lock seven elements

Smart lock is a product of hardware structure + electronics + Internet . If you choose smart lock, is optimistic about 7 key points.

As for additional functions, such as cat eye, face recognition, whether to connect to whole-house intelligence, etc., you can make another choice based on your budget.

good lock body better than everything

A good smart lock, in addition to the C-level lock core being a must-have, the quality of lock body also determines its quality.

fingerprint lock is divided into fully automatic lock and semi-automatic lock.

semi-automatic lock, requires manual locking of the door, using a mechanical lock body, which has high stability and no power consumption, but the user experience and anti-theft ability are poor, and the price is also cheaper.

is truly fully automatic lock, uses an electronic lock body, which has a better user experience, but large power consumption is also a problem.

Be careful!

is true and fully automatic lock. If wants to realize the automatic anti-lock function, it must be a fully automatic lock body, that is to say, must be an electronic lock body with embedded motors.

In order to reduce costs and reduce the price of automatic locking, some manufacturers will use mechanical self-elastic lock body.

This lock body is driven by an external motor and cannot intelligently rebound according to the switching state of the gate. It can only be counted down. Once the time reaches the motor, the lock tongue rebounds, so this lock is particularly noisy.

When purchasing a fully automatic lock, you must distinguish whether the lock body is a mechanical self-elastic lock body or an electronic lock body.

lock body specifications, generally has a 6068 lock body, which has a high degree of adaptability to anti-theft doors.

and Overlord lock body . It has a larger size and two anti-locking tongues, similar to the heaven and earth hook. If the security door at home is not like this, you don’t need to change it deliberately.

If it was originally this kind of lock body, changing the smart lock requires communicating with the merchant in advance, and installing will be charged an additional fee.

Don’t worry about the true and false ferrule . The only difference between the real and false ferrule is whether the lock core is exposed after violently removing the panel.

has begun to violently unlock, and it is inevitable that the lock core will be damaged, so you don’t have to pay attention to this issue when purchasing.

Purchase points:

Fully automatic lock, be sure to choose the full automatic lock body

semi-automatic lock, ordinary double fast lock body

Unlocking method is not the more the better

In addition to fingerprint and key unlocking, smart locks also include WiFi, Bluetooth , password, APP remote unlocking, and facial recognition unlocking.

But the more ways to unlock the lock, the higher the risk of being stolen by others.

For ordinary families, fingerprint + password + key are enough.

There are family for the elderly and children. You can add card unlocking or face-scanning.

Face recognition is currently used in many fields. Just like mobile phone face-scan payment, 3D structured light is used. After experimental verification, photos and videos cannot be unlocked.

However, facial recognition unlocking has a disadvantage, that is, when there is a large traffic in the corridor, anyone should recognize it at a glance, so it consumes a lot of power, and it will automatically issue a welcome voice in the middle of the night, which is quite scary.

So when purchasing, you should choose a facial recognition function that can avoid such situations.

Bluetooth unlocking is a waste of , mostly used for rental housing.

WIFI, APP is more suitable for home use , remote information exclusive, power warning and alarm functions.

But at present, because the security factor of the home IoT is too low, it is easy to be cracked. If the purchased smart lock has these two unlocking functions, you can choose to turn it off.

Cat eyes should be prevented from theft and children's pet unlocking

cat eyes unlocking is a common method of theft, as well as plastic sheets, magnets and other methods.

If there are elderly people, children and pets at home, you should prevent them from being opened by mistake.

to deal with this situation, just buy the smart lock with anti-lock function. Some high-end products come with visual cat eye function, and you can see everything outside the door.

Currently, smart locks have anti-trial and anti-tripping functions, which are security hard requirements.

As for other functions such as automatic alarm, , generally speaking, the more complete the function, the stronger the lock's defense ability, but the false alarm rate will also increase accordingly.

handle model is more stable, push-pull model is more convenient

smart lock is divided into two types: handle-pull and push-pull .

Hand-hand looks close to traditional mechanical locks with independent handles, and the price is basically below 1500.

is cheap and has good stability, but the steps to open and close the door are relatively cumbersome, and the user experience is not that good.

Push-pull adopts a handless design, and some models are also integrated panels.

has the advantages of being high-looking, simple door opening and closing, and has a natural anti-cat eye lock-opening function; the disadvantage is that the price is high, most of which are above 1,500 yuan, and it consumes a lot of power, which is not suitable for the world hook door.

battery power does not need to be confused

At present, semi-automatic smart lock uses mechanical lock core , which uses dry batteries. Generally, the battery life of 4 No. 5 dry batteries is about half a year. Remember to replace the battery in time.

and electronic lock core usually uses lithium battery . Lithium batteries are more environmentally friendly and require frequent charging. It is best to buy one with a low battery prompt, otherwise it may still be locked outside the door.
