Some people say: Never install a fingerprint lock in a new house. Is this reasonable?

It doesn't make sense. I am the kind of fingerprint door lock research and development engineer who has been designing and producing for more than 20 years. Before the popularity of mobile phones, fingerprint locks were unstable, mainly because the fingerprint identification technology was quite poor. With the development of mobile phones and the intervention of cutting-edge scientific and technological personnel, fingerprint recognition technology and face recognition technology are quite mature now. After the completion of the residential area, it is not uncommon to install fingerprint locks as a whole, and the operation is basically good.

Due to professional requirements, I installed fingerprint locks in many places, or newly-built smart doors were locked in other people's buildings. The locks of these buildings come from three lock factories. The phenomenon is summarized for everyone.

First, the installation problem, three-point manufacturing and seven-point installation, is more suitable for smart door locks. Intelligent door locks are different from ordinary mechanical locks. Is "exquisite", intelligent door locks can be roughly divided into two types: fully automatic and semi-automatic. Semi-automatic to say, its clutch device is in the panel, your lock body and panel are installed correctly, and the rotation direction is correct. Generally, the problem is not big. Many users, if I send an installation video, can generally install it themselves. The effect is good.

Fully automatic is much more troublesome. You see, the mechanical lock turns the handle by hand, and the lock tongue retracts into the lock body, but it is not installed. If it is a big deal, it will be more difficult to do it manually. Automatic intelligent door lock, after receiving the instruction, relies on a small motor to retract the lock tongue into the lock body, and the power of this small motor cannot be too large. It's too big and consumes a lot of power. Unlike a mobile phone, this lock can be recharged at any time. No one charges with a lock all day. It was fun. How long it takes to fully charge is also an important indicator for us to examine the performance of the door lock. Therefore, when installing the fully automatic intelligent door lock, it should not be stuck and should be smooth. We generally require the automatic lock not to be connected with the hook on the door, just because of the power concern of this small motor. Smart door lock has been installed. Make sure the door lock works.

Second, in the market, smart door locks are mixed and the competition is fierce. As we all know, price is the most sensitive thing for buyers, and no layman knows the cost of a smart door lock. Cutting corners is the specialty of some smart bosses. The panel is as thin as a piece of paper, using old chips and low-level fingerprints, which is a mess. This kind of thing can be used for a while, but how long will it last? I'm afraid he can't tell himself. In addition, the lock body of the intelligent door lock borrows the lock body of the mechanical anti-theft door lock. This lock is also a five-yuan lock and a sixty-yuan lock. Now the market transparency is so high that only laymen don't understand it. Therefore, as long as it is a smart door lock made according to standards, genuine materials and strict technology, it can be used with confidence.

Third, the function of smart door locks is becoming more and more convenient, but behind the upgrade, there will definitely be some so-called hidden dangers. Let's start with full automation. Let me talk about a representative function: remote monitoring. This function is good. All you have to do is turn on your family's WIF III and match it with your mobile phone. You can see the scene in front of your house on your mobile phone. However, the door lock, like a mobile phone, is always on standby. Do you think it consumes electricity? Of course, you can also turn it off on the menu. As you can understand, the more functions, the greater the possibility of failure. Well, you can weigh it yourself.

Fourth, misoperation, this is mainly automatic lock. One, one-button remote unlocking, no matter who rings the doorbell, the head of the keyman and the unlocking instruction symbol will appear on your mobile phone. If you click this symbol, your door lock will be opened. At this time, you should be careful. Look carefully and then point the symbols to avoid misoperation. Secondly, some doors are self-elastic, that is, after the lock tongue retracts into the lock body, the doors automatically spring open. Especially face recognition. You take a look, the lock opens and the door slams open. You don't know. The door was open when people left.

Tell me about my experience in installing fingerprint locks: I sometimes have a bad memory and my keys are easy to forget, so I want to replace the locks of developers when I move to a new home. At that time, it happened that the fingerprint lock was engaged in activities after the Spring Festival. Fingerprint locks worth 999 yuan, 399 yuan installed at home. I bought one when I felt particularly suitable, and the master installed it a week later.

It's very convenient to input fingerprints, so you don't have to worry about finding the key anymore. There are three ways to unlock the fingerprint lock: fingerprint, Bluetooth button and password. If the first two methods fail, it is very convenient to enter the password to unlock. Less than a year later, an unexpected thing happened.

I was at work that day, and the housekeeper of the community called and said, you should go home quickly. Your fingerprint lock doesn't seem to work, and my legs are weak with fear. I couldn't go back because I was busy at work for a while, so I asked the housekeeper to help me see what was going on. The housekeeper took the mobile phone, turned on the video function and filmed the whole process. I saw the housekeeper gently twist the handle of the fingerprint lock with her hand. The door opened and there was no fingerprint at all. Seeing all this, I was too shocked to say a word. My heart is racing and my legs are weak. I quickly put down what I was doing and got on the bus and went home.

It turned out that the new tenant of the neighbor changed the lock, and told the lock changing master that the fingerprint lock was better, so he moved my fingerprint lock conveniently. Coincidentally, it opened at once. He felt that things were sudden, and he was afraid that his family would misunderstand him, so he wanted to explain. When he found that no one at home felt bad, he called the housekeeper. I quickly called the after-sales staff of the fingerprint lock, but fortunately, the customer service said not to worry, and immediately contacted the master. Anxious waiting, I looked at every corner of my home, but fortunately I didn't lose anything.

An hour later, the assembler came home to check that the battery was dead, and the fingerprint lock would open the free mode, which has become a mode that anyone can open. This explanation is obviously unreasonable. This fingerprint lock is an unqualified product, which has serious security risks. If the fingerprint lock is dead, it means you can enter and exit freely. Is it safe for me to press the fingerprint lock? Really speechless! There is nothing to lose. If something is lost, who is responsible? Then I negotiated with the manufacturer, and after many times of communication, the manufacturer promised to give me a safe and reliable fingerprint lock, which was expensive and solved the urgent need. We suggest that you install a fingerprint lock with big brand and high safety factor, otherwise don't press it. This is my first time to install a fingerprint lock. Is it scary?

Be sure to install a fingerprint lock for the following reasons:

First, the operation is convenient. Needless to say, everyone knows this.

Second, the security level, different levels of fingerprint locks, different security indexes, the nature of mechanical locks is the same;

Third, eye monitoring, now home society, community, and even home, cameras are everywhere, and monitoring is everywhere;

Fourth, awareness of prevention. In the intelligent age, generally, we don't put a lot of cash at home, and large items won't be stolen, and the number of burglaries will gradually decrease. However, we should not relax our awareness of prevention and pay attention to safety.

Am I right? Welcome to comment!

You can install it, but you need to buy advanced fingerprint locks, thousands or even more, otherwise it will be easily cracked by magnets, and there are more and more magnetic interference technologies.

It's good. I mean the tattoo lock.

Is there such a saying? That's news to me.

It's convenient, but there are occasional identification problems, especially in dry and humid weather.

Some people's fingerprints are not easy to use, and then the fingerprint lock is unlocked after burning, which is not safe.
