Do not tangled, and tell you how to choose the way to open the smart lock in one minute?

In recent years, smart locks have gradually entered everyone's perspective. Even Luo Luo has released three smart locks at its own conference. It can be said that smart locks already have sufficient hardware conditions, and many people are also prepared to purchase a smart lock to add convenience to family members. Just looking for relevant information on the Internet will be even more tangled.

Because there are too many issues to consider!

There are push-pull and push-down methods for opening the door. Is it safe to use fingerprint identification? Is it necessary to check whether the door hooks are needed or not? Is the remote door opening function an essential function or a security risk? These issues, etc. are in the process of purchasing smart locks. Take it into account.

Let's start with the basics: open the door .

Today, smart locks are roughly divided into two main genres on the way to open doors: push-down handles and push-pull handles . Push-pull handles are relatively new, and the appearance of Korean dramas has also greatly increased the popularity of smart locks in the country. The press-down handle is relatively more traditional and the mass foundation is deeper. People who see it all know how to open the door.

Push-pull handles are indeed novel, but due to their structural reasons, the lock body generally does not support the heaven and earth hooks (after the text will elaborate on the problem of heaven and earth hook). And it uses a fully automatic lock body that cannot be manually locked and can only wait for the lock body to automatically lock. There is not much problem in using the pressed handle, and the lock body generally supports the heaven and earth hooks, but the lock body is not a full-automatic lock body. When the lock is unlocked, it is necessary to lift the lock, and one more step is required, which is relatively cumbersome.

Push-pull smart lock use novel

Therefore, for the basic method of opening the door, the two have a chance to win each other, which is enough to make people tangled for a while. However, it can be more than one problem. Fingerprint recognition is also divided into two genres on the technical level. If the competition between open and closed methods is to meet the aesthetic and preferences of more people, then the fight for fingerprint recognition is "in the name of security."

Is fingerprinting really insecure?

From a principle point of view, the security of capacitive fingerprinting, which is very popular today, is already high enough, but some people think that as long as the fingerprint is copied by the conductive adhesive, fingerprint recognition is no longer safe. This sentence seems to be true, the fingerprint of the conductive adhesive does have the possibility of verifying by fingerprint. However, the point is this: However, if you do not want to take the initiative to copy fingerprints, it is more difficult to copy the fingerprint than to remove the door lock.

General fingerprint film cannot be detected by fingerprint of smart lock

The author once made a fake fingerprint to test the security of fingerprint recognition. The production process is relatively long. It is necessary to bake the mold first, and then press the finger on the mold for a minute. This one must not tolerate a minute and never let go. Stiffness, but also to endure the risk of being burned in a minute, the entire fingerprint template is scrapped when it is burned out of the blisters. One minute later, the pre-configured silicone gel was applied to the mold for one hour. There are more than one hour, for someone else's home lock can go five or six households, but also took a look at fingerprints by fingerprints dried cocoon......

The two ways of fingerprint recognition is also a point that makes people tangled: Capacitive fingerprints are relatively safe, but their service life is really a problem; optical fingerprints are more durable, but fake fingerprints can be easily cracked.

Both fingerprints have their own advantages (Source: Tmall Mall)

I believe that life expectancy is not a problem that needs to be worried. Smart locks are electronic products and will inevitably have a certain life span. However, this lifespan is more dependent on the mode of use. The life of a capacitive fingerprint head can still be done without malicious destruction. To mate with the end of the lock, so try to choose the capacitive fingerprint head on it.
