When buying a smart lock, it is sometimes stunned by complicated slogans and functions. After all, smart locks have intelligent features. Although they have many functions, sometimes they don't know what features these smart locks have. They don't know who to compare with. I'm here to summarize some of the features of smart locks. Their respective advantages and disadvantages can help you to choose the right smart lock.
Fingerprint recognition VS password unlock
Advantages of fingerprint unlocking: Smartphones with fingerprints unlocked are now very common, and fingerprint recognition has already flown into the homes of ordinary people. The characteristics of fingerprint recognition are also very obvious: easy to use; and the fingerprint key is very complicated, the repetition rate is also very low, and the security is very high; not only that, the fingerprint recognition of the smart lock can also be set differently for different people. Fingerprint permissions; today's fingerprint recognition speed is very fast.
Advantages of fingerprint unlocking
Fingerprint unlocking disadvantages: However, fingerprint recognition still has shortcomings. A person has only ten fingerprints in his lifetime, and cannot change the shape of the fingerprint. When verifying the fingerprint, he must free his hand to extend a fixed finger; many fingerprint recognition due to technical and The cost limit does not allow wet hands to unlock; some elderly and children's fingerprint collection is more difficult, and it will take time and effort to verify. Although the cost is high, the fingerprint is relatively easy to obtain, and the fingerprint recognition of some smart locks does not have the characteristics of living recognition, and is relatively easy to be cracked.
Shortcomings of fingerprint unlocking
Advantages of password unlocking: Passwords have existed in human production and life for a long time, but they have not been completely eliminated. The reason is that the characteristics of passwords are easier to remember, and the length of passwords can be customized, and passwords can be modified at will. Many smart locks with password unlocking have the function of virtual password and low-privation temporary password to ensure the security of the master password is not leaked.
Virtual password function
Password unlocking disadvantages: You need to change the password frequently to ensure security, but this will lead to the password often being missed; even if it is a dummy password, you can open the door if you input it as it is. It is a disadvantage to unlock the password without the fingerprint being unlocked.

Summary: Fingerprint unlocking and password unlocking are two common unlocking methods for smart locks today. Each has its own advantages and disadvantages. Although there are also two smart locks for unlocking, even some smart locks have three or four unlocking methods. However, on the one hand, this kind of smart lock is relatively expensive, on the other hand, the smart lock is born for safety, and the unlocked entrance is still made safer. If there are no elderly people or children in the family, two kinds of smart locks can be chosen at will. If there are old people or children in the family, it is recommended to purchase smart locks with fingerprints as the main unlock. After all, fingerprint unlocking does not require memory, and you can open the door when you walk to the door. Still more suitable for the elderly.
There is a spare mechanical lock VS no spare mechanical lock
There are advantages of spare mechanical locks: Many mechanical locks have a mechanical lock as a backup. The advantage is that if the smart lock is dead, you can use the mechanical lock to open the door lock, which is in accordance with the usage habits, and you don't have to worry about losing power at any time. You can also lock the mechanical lock. For the elderly, it is more in line with the old people's habits, but also reduces the shortcomings they may need to remember the password. The mechanical lock part of the reliable smart lock will adopt the new national standard C-class lock cylinder, and the safety will be much higher.
C-class lock cylinder is the highest safety lock cylinder
There are shortcomings of spare mechanical locks: some smart locks use a mechanical lock with lower safety for cost considerations, and the lock is a product that follows the principle of wooden barrel. If the wooden barrel has a short board, the safety will depend on The short board of the board. On the other hand, the biggest feature of the smart lock is not to bring the key, but in order to be afraid of no electricity, it is necessary to give the smart lock with the key every day. In addition, the key will be lost. If you accidentally lose it, the cost of replacing the lock is very high.
Smart lock with spare mechanical lock
No spare mechanical lock advantage: no need to carry the key, no need to worry about the key will be lost, more suitable for people who often go out but lost, and manufacturers will definitely have a backup solution, such as charging the mechanical lock emergency charging, in the battery Give a reminder to change the battery before the power is turned off.
Smart lock with mechanical lock will also provide emergency charging port
No mechanical spare lock Disadvantages: Charging treasure is not something that everyone will bring, and now the data interface of the mobile phone is confusing, the Apple mobile phone is a separate one, the charging line of the Android mobile phone is divided into MicroUSB interface and type-C interface, although the future The USB interface is definitely the world of type-C interface, but now considering the popularity, it will definitely give priority to MicroUSB for charging, so that the data line will be incompatible in the future, it will be very troublesome at that time.
Emergency charging port will soon be replaced
Summary: In the presence or absence of spare mechanical locks, many manufacturers will give priority to having a mechanical lock as a backup. After all, the difficulty of unlocking a C-class mechanical lock is relatively high and will not become a short board for the entire smart lock. It is more suitable for people who have old people at home, or who are accustomed to mechanical locks, or who are not open when they go out for a few months.
Remote control VS no remote control
Advantages of smart lock with remote control: The feature of smart home is remote control. The smart lock with remote control function can also realize the functions of remote door opening and remote monitoring. It allows the nanny or relatives who arrive home early to enter the room after passing the license, making the door lock more convenient.
Remote lock connection unlock function of smart lock
The disadvantage of having a remote control smart lock: However, the remote control function also brings security problems. Although smart door locks are now a relatively unpopular thing, people who can crack smart door locks can also work with hundreds of thousands of dollars a year. Will not be willing to go to the door to shackle. But with the passage of time and the popularity of smart locks, smart locks will also become the target of hackers.
Smart locks will become the target of hackers in the future
Advantages of smart lock without remote control: Compared with smart lock with remote control function, smart lock without remote control is a separate device, and security is not affected by the network environment in which it is located. From the perspective of network security It must be seen that the smart locks that are not physically connected to the Internet are more secure.
Bluetooth unlock can be used instead of remote unlocking
Shortcomings of smart locks without remote control: But there is no remote control function. For smart locks, the inconvenience is also more. If there are relatives and friends visiting themselves but not at home, there is no way to open the door for the guests to enter the house. Or if the door is smashed, you will not have the information to remind you and the door lock, so it is not very convenient.
Summary: The remote control of smart locks will not be much dangerous now, but with the popularity of smart locks, the security of remote network connections should be gradually improved. In terms of the security of the remote control of the smart lock, the smart lock for remote control opening is more suitable for families with babies or pets in the home, and can know the situation at home and the visiting guests in real time.
