The choice of unlocking method (highlight)

Since it is called a smart door lock, it must be a variety of ways to open the lock, but we are most commonly used in fact, so one, such as you mainly use fingerprints to open the lock, then you will hardly use the password, key or NFC, so the first focus of the choice of door lock is to choose the most suitable for your unlocking method. The most common and most commonly used smart door locks on the market are generally divided into: fingerprint recognition, face recognition and finger vein recognition.

Fingerprint recognition for the crowd: young people, fingerprint clear. Fingerprint recognition of the smart door lock is the most common and the largest retention, the price is relatively face recognition and finger vein recognition is also on the low side, for fingerprint clear people or very convenient, home to reach out and point.

Face recognition for people: the elderly. Face recognition is of course available to all ages, but it's super friendly to seniors. Face recognition relies on the camera on the door lock to 3D scan the person standing in front of the door to determine if it is a stored user and thus whether to unlock the door.

Many elderly people's fingers can be chapped and unclear, and it is difficult to recognize such fingerprints with traditional semiconductor fingerprint recognition. This is the reason that Lao Ji to Mom and Dad to upgrade the fingerprint lock to face recognition. Before Mom and Dad came home most of the time is used to enter the password, fingerprint module has become a display instead.

After replacing the door lock, I even unintentionally found that the password button area has been rough fingerprint grinding traces, encounter with the intention of people can easily guess the password, thus burglary or even injury, I believe that you can easily guess the common button in the following figure is 124589.

Finger vein recognition for people: middle-aged and elderly people. Finger vein recognition is a safer and friendlier identification method than semiconductor fingerprint recognition, which relies on scanning the veins under the skin of the finger and recognizing the image of the veins formed after the absorption of infrared light by the hemoglobin in the comparison blood to identify the user, with a high security level.

Conclusion: There is no elderly daily use of the words preferred fingerprint recognition lock, the price is relatively low under the premise of enough to meet the needs of use; there are elderly daily access to the family preferred face recognition and finger vein recognition, between the two, the current epidemic serious finger vein can be identified without taking off the mask, you can give priority to.

Other unlocking methods such as one-time password, nfc, emergency keys are standard features of smart door locks, which are not very useful and do not require much consideration. It is worth mentioning that like smart home partners to consider more access to the Mijia door locks, work to lock the door, open the door after work can be linked to some home appliances such as home from work automatically open the TV, work to leave home automatically start the floor robot.

Comfort options (more important)

As if the automotive industry upgrades such as keyless entry, seat heating and ventilation, steering wheel shift paddles, without these features car can also be driven normally, but these features will allow some users to use more comfortable. Of course smart door locks are not like cars can be retrofitted with modifications, meaning that when choosing a door lock according to their needs, choose a door lock equipped with the features we need.

So what are the common options for smart door locks? Electronic doorbell, cat eye, battery configuration, etc.

Electronic doorbell is the sensor button on the outer door handle, visitors such as couriers do not need to knock on the door, just press the doorbell, the people inside can hear. Advanced electronic doorbell in addition to the basic functions, but also on the phone to remotely receive a reminder to press the doorbell, you can open the app and the person outside the door intercom.

There are also advanced electronic doorbell has a voice change function, a girl living alone can open the app to start the voice change, tell the delivery man or courier to put the items at the door can leave, and then open the door to pick up the items.

There are also some smart door locks installed in the door handle electronic cat eye, in addition to someone ringing the doorbell can be silent on the phone to view the person outside the door and intercom, electronic cat eye also has a warning function, when someone stays in front of the door for a long time or repeatedly wrong attempts fingerprint code, electronic cat eye will automatically record the suspicious person and send to the phone.

The house I purchased in Zhuhai has been inaccessible because of the epidemic, and all this time I have been relying on the cat's eye on the doorknob to let me know whether it is a courier or someone knocking on the door, so I can rest assured that I am not in Zhuhai.

These two functions if you do not need, such as your family has several people living in your home, there is often someone, it is not necessary to spend extra money to buy the doorbell and cat-eye function, choose a smart door lock that contains only the basic functions can make the door lock more cost-effective.

In addition to the cat's eye and doorbell, some smart door locks can also be connected to the Apple Smart Home homekit, home from work if wearing a mask, hands end of things, that fingerprint, face and finger vein can not be used, then as long as you shout "hei Siri, open the door lock", through the Bluetooth gateway pairing door locks can automatically unlocked.

The standard basic smart door lock 8 lithium-iron batteries to achieve a year of use of fully automatic door lock life, semi-automatic door lock requires only 4 batteries. The cat's eye, doorbell and such additional power-consuming features will accelerate battery consumption, so we must choose the cat's eye function with dual batteries.

Dual batteries are lithium-iron batteries to power the chip and lock cylinder to open the door. Rechargeable lithium batteries are for the cat's eye, dual systems operate independently, even if the cat's eye lithium battery is dead, only the cat's eye function can not be used, the unlocking of the door lock is not affected in any way.

Some smart door locks with cat eyes choose to unify the power supply, or the use of 8 lithium batteries, or a common use of a rechargeable lithium battery (usually a spare lithium battery for exchange), in my opinion, this will reduce the life of the lock, improve the frequency of battery changes, so that the convenience is reduced, less recommended.

Conclusion: cat's eye, doorbell non-essential, on-demand purchase, preferably with dual batteries.

Lock body structure

Smart door locks on the market are divided into two types of fully automatic and semi-automatic locks. Fully automatic locks are fingerprint recognition through the lock body of the motor will automatically rotate to unlock the lock core, you just gently pull the door open to enter. And semi-automatic door lock is a bit like the indoor bathroom door handle, unlocked you need to manually press the handle to unlock the door tongue and then pull the door open to enter.

Semi-automatic locks are now increasingly rare, mainly installed on entry-level smart door locks such as Xiaomi E and Cadiz F1 below $1,000, suitable for out-of-pocket installation on rental rooms. If you look good door locks over a thousand but still use semi-automatic lock heart that will not hesitate to pass off on the right.

Conclusion: Preferred fully automatic (except for very low budget)

Networked or not

Most smart door locks can be networked, some through the Xiaomi gateway, some through their own gateway, and others can Wi-Fi direct connection to the router.

Lao Ji also used the door locks that can not be networked, such as the following, you want to add fingerprints, passwords, etc., press the set button on the door lock, and then press the corresponding key according to the voice to operate step by step, just like calling a bank customer service phone.

So what can door lock networking do? The most common is to issue a one-time password. Friends and family visit, you happen to go downstairs to buy food or encounter traffic jams have not yet arrived home, let people wait outside the door is not very polite, you can open the one-time password function, visitors use the one-time password to enter, the password will automatically expire, safe and avoid embarrassment.

In addition to the commonly used down one-time password, smart door locks that can be networked will send alerts to your phone when you encounter multiple incorrect passwords and fingerprint attempts to unlock. And we can also check the status of the door lock remotely to see which user has come in and out, whether the door is fully locked or falsely concealed, etc.

Conclusion: Must choose networkable.

Additional security aspects

Smart door lock to remove the intelligence, it is the essence of the door lock, the most important thing about the door lock is not how smart it is, but security. For violent breakage we will not discuss, there is no lock that can resist violent breakage.

For technology to pick the door, the lock cylinder is the first line of defense in the face of uninvited guests, we have to choose to use the C-class lock cylinder, which can effectively delay the speed of prying, so that the beams know how to retreat. More than $ 1,000 smart door locks are basically standard with a C-class lock cylinder, this we just need to look a little.

And clever beam in order to avoid the trouble of lock picking, the invention of the cat's eye pry door method - the use of professional tools from the cat's eye to reach in and pull up or press down the door handle to achieve open the door.
