Smart door lock It has always attracted much attention. Although its price is much higher than that of traditional mechanical door locks, smart door locks can solve the problem of forgetting to bring keys or losing keys, and accurately capture everyone\’s needs.

So compared to traditional mechanical locks, smart doors What issues should you pay attention to when choosing a lock? Today we will learn about it in detail.

1. Choice of semi-automatic and fully automatic smart door locks

Smart door locks are mainly divided into two styles: semi-automatic and fully automatic. Judging from the appearance, smart door locks with traditional door handles are generally semi-automatic; while smart door locks with push-pull handles are generally fully automatic. Automatic style.

1. Semi-automatic smart lock

After the semi-automatic smart lock is unlocked by fingerprint (or other unlocking methods), because it cannot complete the door opening action completely autonomously, it needs to lift or press down the \”door handle\” to complete the door opening. In addition, it also needs to be lifted up after closing the door. Or press down the \”door handle\” to lock. Therefore, the semi-automatic smart lock mainly solves the pain point of \”forgetting to bring the key when going out\”. As for other aspects, it is not much different from traditional mechanical locks. In addition, the price is also more acceptable to mass locks.

​2. Fully automatic smart lock

After the fully automatic smart lock is unlocked by fingerprint (or other unlocking methods), the lock tongue will automatically retract. We only need to gently push or pull to open the door, and when closing the door, we only need to close the door. The lock tongue will also pop up automatically for anti-locking! Compared with semi-automatic smart locks, fully automatic fingerprint locks are more convenient to use, but the price will be relatively higher and the power consumption will be higher, so smart locks Charging frequency will also be higher

​2. Issues you must know about fingerprint unlocking

At present, there are two main fingerprint unlocking technologies in the smart lock market: semiconductor biometric fingerprint and optical fingerprint.

1. Optical fingerprint

It uses the ridges and bones of fingerprints to reflect light differently to form images (fingerprint check-ins at work are basically based on the principle of optical fingerprints), and as long as the fingerprint lines are clear and consistent, it can be recognized without any need Vitality fingerprints are easy to be unlocked by copied fingerprints, so it is conceivable that the security is relatively poor.

2. Semiconductor biometric fingerprint

Semiconductor biometric fingerprints can identify living fingerprints. The fingerprint recognition accuracy is high, it is not easy to be unlocked by copied fingerprints, and it is highly secure.

​3. Real ferrules and fake ferrules

The lock core of smart locks has two types: real mortice and fake mortise. Corresponding to the mechanical key unlocking method.

Besides the appearance, the biggest difference between the two is that the \”real mortise\” has a mechanical keyhole on the appearance panel of the lock body; while the \”fake mortise\” has a mechanical keyhole on the appearance panel of the lock body. There is no mechanical keyhole, which is usually at the bottom of the lock. It is easier to give people the impression that \”the fake insert has no keyhole\”. Does it look higher grade?

In addition, whether it is a real ferrule or a fake The insert is not the final factor that determines the safety of the door lock! If you see this being used as a marketing gimmick, it contains too much water, so it is recommended to choose carefully!

So, what determines the safety of the door lock?

In fact, whether it is a traditional mechanical lock or a smart lock, their core is the \”lock cylinder\”. At present, the security level of the lock cylinder has three levels: A, B, and C; among which, A is the The time for technical cracking is about 1 minute, the time for level B anti-technical cracking is about 5 minutes, and level C is the highest security level at the moment. It also has the function of anti-torsion tools to open the lock cylinder.Yes, it will self-destruct and lock.

​4. Anti-little black box

The principle of the small black box is to use a strong magnetic field to destroy the control chip of the smart lock, causing it to automatically unlock.

Although, all the following smart lock brands It has been designed with an anti-little black box upgrade, and has the \”anti-little black box\” function by default. However, it is recommended that you check carefully whether it has this function when purchasing, because it is not ruled out that some models do not have this function.

Without this function, the security is almost is 0!

​5. More and less functions

The functions of a smart lock are actually linked to the price. The more functions, the higher the price.

The functions include: coercion alarm, lock picking alarm, dummy password to prevent tracking, cat eye prevention, small black box prevention, and multiple unlocking methods (Respectively, there are face recognition, fingerprint, password, double password, mobile App, temporary password,
