There is a kind of lock called \”Smart Lock\”. Unexpectedly, this technology that once appeared in science fiction movies has now become a standard feature in new home decoration. It seems that only when a smart lock is installed at home can the \”evolution\” of the home be completed!

The \”smart lock\” is like this: when you approach the smart lock, it will automatically unlock based on your identification information, full of intimacy; can be connected to the Internet to remotely monitor home security , some functions also include card swiping, password, and key opening modes for selection.

But why do many people find out after buying smart locks: The \”fingerprint recognition rate of 99%\” claimed by the manufacturer is just a gimmick.Errors often occur during actual identification; The function of the lock core is not as good as that of ordinary mechanical locks… But this is not a problem with the smart lock itself, but because it was bought wrong!

Faced with the dazzling smart locks with dazzling function promotions on the market, buyers often face such wrong choices: The door frame is not big enough but chooses a large one model; optical fingerprint recognition with low security…Today, I will teach you how to choose a smart lock correctly!

1. Before choosing a smart lock, do not choose these structures

Never choose a low-security optical fingerprint recognition smart lock

Most smart locks on the market today use semiconductor biometric fingerprint recognition, which uses the current signal pressed by the finger on the sensor. Identification is more secure.

Optical fingerprint recognition technology uses optical imaging to identify fingerprints. The risk of theft is extremely high. Once the same finger has been identified on the optical fingerprint lock, the identified fingerprint may be stolen by hackers.

>>To determine whether the fingerprint lock is optical or semiconductor fingerprint recognition, look at these two points:

Point 1. Once the red light is emitted, it means optical recognition, don’t buy it! >

It is quite simple to determine whether the fingerprint lock is optical fingerprint recognition or semiconductor fingerprint recognition. Just observe whether the fingerprint recognition area emits red light

The optical fingerprint recognition area emits red light, while semiconductor fingerprint recognition is light-free. But there are exceptions. Some smart locks will emit red light when encountering low light or large light difference environments, but will not start to recognize

Point 2. The touch screen uses semiconductor fingerprint recognition, don’t be greedy for small gains

It is not accurate to just look at the luminous point. Some merchants will use this as a selling point to deliberately make the recognition area of ​​the optical fingerprint lock larger. Real semiconductor biometric locks have no light, and their fingerprint recognition area is larger. They use multi-touch technology.

If the fingerprint recognition area of ​​the lock is smaller, And the light intensity and color depend on the light conditions of the surrounding environment. It must be semiconductor biometrics

Never buy a real ferrule only to find that it doesn’t make much sense. Tangled

In recent years, almost all security locks or anti-theft locks in the market emphasize real inserts. Some people never expected that they would be too entangled when buying locks. \”Real mortise\” is a waste of money.

\”Real mortise\” refers to the corresponding slot connection between the lock cylinder and the lock body. In fact, most locks already have it. Core + auxiliary core + marble separate structure. Unstructured locks generally pay more attention to anti-theft, and the lock heads and slots are fake. No \”real insert\” is needed at all.

2. When choosing a smart lock, you must not choose these functions

NO.1 You must not choose a handle-type smart lock, the push-pull type is better

At the same time, it is not recommended that you choose a handle-type smart lock. It is not much different from an ordinary mechanical lock. The operation is complicated and you need to master a certain amount of force to open the door. .

A real smart lock should be push-pull. Whether it is a built-in motor sliding door or a rear-mounted clutch lock, they are generally more user-friendly than handle-type smart locks. Just push and pull to open the door!

NO.2 Never choose an ordinary fingerprint lock, choose one with a high recognition rate.

In fact, smart locks are not all fingerprint locks. Fingerprint locks are a type of smart lock. There are also password locks, window locks, etc. on the market. Take fingerprint locks as an example. They are not only divided into ordinary fingerprint locks, optical fingerprint locks and semiconductor fingerprint locks but also planar fingerprint recognition and 3D fingerprint recognition.

You must not buy ordinary fingerprint locks and optical fingerprint locks with low recognition rate and slow recognition speed. Semiconductor fingerprint locks are more effective. Consider 3D fingerprint locks with higher recognition rates and better accuracy.

>>When choosing a smart lock, it is most reliable to take the elderly and children to try it on site

Take ordinary fingerprint locks and semiconductor fingerprint locks. In comparison, the recognition rate of ordinary fingerprint locks is only about 20%, the recognition speed is 0.5-1 seconds, and the recognition time is much slower!

If you want to choose a smart lock with high recognition rate, you must take the elderly and children to the on-site test. In fact, their fingerprints are roughly the same as ours. If their fingerprints can be quickly identified, it will be suitable. Used by the elderly and children at home.

NO.3 Don’t buy a smart lock that has many functions but no useful functions. It is a waste of money.

Many people buy smart locks. It seems to have many functions. When it is necessary to open or close the door, it is recorded on the mobile phone. But is this kind of function really practical? It consumes too much power and is prone to false alarms.

Really high-performance smart locks should be small but refined, with functions such as low battery reminder, easy replacement of door lock battery when low battery is low, no sound when opening the door, easy replacement of lock core, and shut down when needed. .

3. In fact, when choosing a smart lock, it is a misunderstanding to choose a lock cylinder that is easy to be picked

Mistake 1: Choosing an A-grade lock cylinder can easily be unlocked by a bolt. A grade C lock cylinder is recommended

You must know that the biggest misunderstanding is choosing a lock cylinder that is easy to be picked. Grade A lock cylinders have the lowest security level and are easy to be unlocked by bolts, etc. Once the door is opened, it is easy to be invaded by casual thieves.

Don’t think that you can choose a high-security lock cylinder by spending more money. In fact, lock cylinders also have grades. Currently, the most secure ones include C-class lock cylinder, B-class lock cylinder and A-class lock cylinder. C-class lock cylinder has the highest safety. If you want to save worry and money, choose C-class lock cylinder Just lock cylinder.

Mistake 2: The selected lock cylinder is too small and can easily be opened by violence. All kinds of lock bodies are suitable.

Some people just want it to look beautiful. , I like to choose smart locks with small lock bodies. Small lock body + small lock core + straight lock body structure. This design directly determines that the lock body is easy to be opened by violence!

Since it is opened by force, hand tools must be used. The small lock body and cylinder are simply not thick enough to block the lock picking tools. Whether it is a push-pull lock or a handle lock, you must choose an anti-theft lock body with a thicker lock body.

The most important thing is that smart locks must have basic functions such as waterproofing, anti-theft, and fire prevention, plus a combination of electronic locks + high-security lock cylinders.Don\’t make it too complicated!

As long asthe lock body and lock body have the above functions, the security level of the lock cylinder is selected as C level, and a semiconductor fingerprint lock with high recognition rate can be selected, coupled with the push-pull unlocking mode,This kind of lock is a cost-effective smart lock~

With the rapid development of technology, the fingerprint recognition function of locks may become increasingly useless in the future. If it can be replaced with a more efficient and safer identity Isn’t authentication technology beautiful?

This also means that fingerprint lock may be replaced, and may be replaced by facial recognition lock, iris lock or extremely miniaturized password lock… There are many possibilities to look forward to.

Of course, many technology companies are also trying to link smart locks with other smart home products. Once the door lock recognizes that a non-family member is approaching, it will activate the alarm to link it. Which smart lock will you choose?
