Your home's smart lock is safe in the end.

The smart lock is actually an upgraded version of the electronic lock. Most of the currently available smart locks are based on electronic locks. The core is still a mechanical lock, but a layer of "smart leather".

The essence of the smart lock is the mechanical lock, but it is equipped with a motor, which supports the electric unlocking method, and then incorporates modern unlocking methods such as fingerprint recognition, password, door card, Bluetooth, mobile app, etc., and becomes a smart lock.

The components of a smart lock

The reason why smart locks are smart is because these locks can be connected with mobile phones. Users can monitor the opening and closing of door locks through mobile phones, and combine registration information to know when family members go out and whether they are safely at home.

One of the big advantages of smart locks is the ability to view portal security.

As a relatively new lock, the safety issue of smart locks is the most concerned by consumers. This kind of lock is not safe in the end. The most important thing is not the "smart skin" outside, but the internal "mechanical core".

The lock cylinder and lock body determine its safety

Choosing a smart lock is actually very bad. First of all, the state stipulates that the electronic lock must have a mechanical lock body and reserve a physical keyhole. Therefore, the inside of the smart lock is still a mechanical anti-theft lock, which means that the consumer has to identify whether the smart part is safe. Easy to use, you have to learn some anti-theft locks to buy knowledge.

Lock cylinder: Super B level is safe

The national standard has developed two safety levels for the lock core, which are A and B. These two levels are basically without security. Therefore, the enterprise standard is super B grade (also called C grade or even super C grade, just Called differently).

Whether it is a smart lock or not, it is recommended to use Super B lock

At present, the super B-class lock core technology has an opening time of 270 minutes, while the A and B grades are 1 minute and 5 minutes respectively. Therefore, if you want to buy a smart lock, you must choose a product with a super B-class lock cylinder.

Hidden keyhole below is not safe

Many smart locks on the market place the keyholes at the bottom of the front panel of the lock, rather than the regular front. This design shows that this keyhole is probably not really passed through the lock cylinder, but is a fake ferrule that can be easily cracked.

This keyhole placed under the door lock panel may not be safe

Therefore, when purchasing a smart lock, try to select the product with the keyhole on the front side. If you can, it is best to check the structure of the lock panel and the lock body before purchasing. See if the lock hole is a fake ferrule.

This is a fake ferrule, the real lock core is the following:

Lock body: motor and clutch must be reliable

It is difficult for consumers to distinguish the quality of the lock body. The material used is not easy to distinguish. The internal motor and clutch are not easy to judge, which brings many problems for the purchase.

Since the electronic lock is unlocked by the motor-driven clutch, the motor and clutch must be durable, and the two components must be in the lock body to avoid violent unlocking.

If the merchant does not display the structural information inside the lock body, then it is only possible to select some manufacturers with certain lock manufacturing qualifications.

Fingerprint recognition is not easy to be cracked

The most mainstream unlocking method for smart locks is the fingerprints we commonly use on mobile phones. There are also various kinds of news about cracking fingerprints on the Internet, which has caused many small partners to have no confidence in the fingerprint recognition method.

Is fingerprint identification itself safe? If everyone is worried about using the various props in the movie to steal your fingerprints and then make a mold to crack the smart lock, then you can wash and sleep.

The fingerprints left in our daily life are all flat. Even if they are copied and printed, it is impossible to fool the mainstream fingerprint identification scheme (whether optical or capacitive), let alone the majority of these. Fingerprints are incomplete.

The fingerprints left in life are not so complete.

The fingerprint recognition methods of some news presentations on the Internet are realized by using the molds of real people to make the film. It is difficult to realize without the original fingerprint master. If you even have your fingers in the hands of the monks, it is not a smart lock. The problem of security is not safe.

In summary, the security of fingerprint recognition itself is very high, and it also brings us great convenience. However, the use of intelligent locks for fingerprint recognition, the product market is a mixture of products, many manufacturers in order to save costs or do not have the relevant qualifications, resulting in the core mechanical lock part is very unreliable, greatly reducing the security of smart locks.

If you are interested in smart locks, it is recommended to filter related products according to some of the above points, choose reliable smart locks, and ensure the security of the portal when you enjoy convenience.
