Smart lock is an indispensable intelligent hardware for modern home and even for smart home life in the future. There is no doubt about it. Looking back at history, the progress of science and technology is always promoted by people's subjective will.Therefore, from the current consumer market of real estate and smart home, smart door lock has become almost a well-known normal consumer product.

Then, the public does not have a mature conceptual understanding of the technical principle of intelligent lock, so what are the basic points to pay attention to when installing intelligent door lock at home?

（1） What is the reason why everyone installs smart locks at home?

1, very convenient!Completely avoid the embarrassment of forgetting, losing or locking the key at home and wandering outside the door;

2, really safe!Overall, the security of intelligent door lock is really much safer than traditional door lock.

（2） What is the difference between the price of smart door locks?

When we choose smart lock, we just like its security and convenience, so the main purchase points also focus on these two characteristics.

The safety depends on the safety level of the door lock, whether the lock cylinder is inserted or not, whether there is a stainless steel anti riot lock body, and whether there is an intelligent security alarm system.

The convenience depends on the number of unlocking methods, power endurance and whether there is an internet module.Let's make a brief analysis one by one.

（3） Key points on safety judgment of intelligent lock purchase

1Why choose CIntelligent lock of level lock cylinder

Most smart door lock brands use class C lock cylinders, but some brands bully consumers and don't understand. They use class B locks.

The level of anti-theft lock cylinder reflects the security level of anti-theft. It is divided into level a, level B and level C according to national standards. You may wish to see the coefficient standard of these three levels of anti-theft lock cylinder:

(1) Class a lock cylinder, prevent technical opening for ≥ 1 minute, prevent drilling for ≥ 10 minutes, prevent sawing for ≥ 5 minutes, prevent prying for ≥ 10 minutes, prevent pulling for ≥ 10 minutes and prevent impact for ≥ 10 minutes.

(2) Class B lock cylinder, prevent technical opening for ≥ 5 minutes, prevent drilling for ≥ 15 minutes, prevent sawing for ≥ 5 minutes, prevent prying for ≥ 15 minutes, prevent pulling for ≥ 15 minutes, and prevent impact for ≥ 15 minutes.

(3) Class C lock cylinder, prevent technical opening for ≥ 10 minutes, prevent drilling for ≥ 30 minutes, prevent sawing for ≥ 30 minutes, prevent prying for ≥ 30 minutes, prevent pulling for ≥ 30 minutes, and prevent impact for ≥ 30 minutes.

The key shape of class C lock cylinder is basically the key with inner milling groove or outer milling groove of single-sided blade, and the type of lock cylinder is side column lock cylinder;The Ministry of public security detected that the technology could not be opened for 270 minutes, and the regional mutual opening rate was zero (1 / 16 million).The marble structure is double row blades and V-shaped side column locking;If the lock cylinder is opened with a strong twisting tool, the interior of the lock cylinder will be damaged, self explosion and locked, resulting in failure to open.

2. lock body of intelligent lock

The mainstream of intelligent door lock uses standard lock body, and a few brands of intelligent lock support customization and change it into overlord lock body.

The standard lock body, also known as 6068 lock body, refers to the length from the center point of the square rod hole to the center point of the lock cylinder hole is 68mm, and the length from the center point of the lock cylinder hole to the side of the lock body is 60mm.

Overlord lock body evolved from standard lock body, and its volume is obviously much larger than that of standard lock body.Overlord lock has two more anti lock tongues, and its security is higher.

Most smart door locks use standard lock bodies by default, but some brands support the transformation into overlord locks, which will involve an additional transformation fee of overlord locks, generally about 150 yuan.Yinke face recognition intelligent lock has standard lock body and Overlord lock body for consumers to choose.

3. difference between true and false lock cylinder

Judging whether the smart lock is safe or not depends not only on the level of the lock cylinder, but also on whether it is a "really inserted lock cylinder".

The "fake" targeted by the "true inserted lock cylinder" installed in the lock body does not refer to the so-called fake or shoddy lock cylinder. This "true and false" actually describes the position of the lock body and lock cylinder.

True inserting lock cylinder means that the lock cylinder is inserted into the lock body. The lock cylinder runs through the whole lock body rather than connected with the panel through connectors. The left side of the figure below is the true inserting lock cylinder;

The false inserted lock cylinder is installed outside the lock cylinder. The false inserted lock cylinder is on the right of the figure below.

The key holes of the smart door lock with the real lock cylinder are openly exposed, which are obvious. The security difficulty of the real lock cylinder lies in the lock body. The panel with the real lock cylinder is a shell. Even if the panel is pried, it does not mean that the core of the lock is moved.

The key hole of the smart door lock with false lock cylinder is hidden. It is usually hidden at the bottom and occasionally placed on the front, but it will not change the fact that the panel with false lock cylinder is the lifeblood. As long as the thief can pry open the panel, the lock is finished.

If your budget is limited and you can only buy medium and low-grade smart locks, it is strongly recommended that you must buy a real smart lock cylinder.

4The smart lock must be able to network and link the smart home hardware and system

The Internet of things is the trend of the future home, and the smart lock is the first entrance to the smart home. According to the trend and development, the smart door lock must be linked with other smart home hardware and systems.

For example, the smart lock can be set to - after work at night, open the smart lock, open the door, the light will automatically light up, the smart speaker will automatically play music, and the cooking machine will automatically start cooking

Yinke intelligent suggests that the purchase and installation of smart locks itself is for the high requirements of the overall quality of life. We must start with real brand smart locks. For example, Yinke's fully automatic face recognition smart lock is not only one of the top ten high-quality smart locks integrating research, production and marketing, but also has good compatibility with other smart homes. The overall feeling will be very cool.

5. the qualified intelligent door lock must have a safety inspection certificate

The popularity and popularity of smart door locks are attracting extensive attention of consumers for their intelligence and convenience beyond traditional door locks. However, while providing intelligence and convenience, can smart locks fulfill its most basic mission - family security?

At present, intelligent lock detection in the field of security is mainly completed by the detection center of the first Research Institute of the Ministry of public security, the detection center of the Third Research Institute of the Ministry of public security, local lock product quality inspection center, UL of foreign detection structure and private third-party detection companies. If it is sold domestically and involves anti-theft, it is generally detected by the first Institute of the Ministry of public security or the third Institute of the Ministry of public security。

At present, in terms of the main contents and items of the test, it mainly includes electrical performance, anti-theft safety performance, durability test, climate and environment adaptability, mechanical environment adaptability, electromagnetic compatibility, electrical safety, key quantity, etc.

Generally speaking, smart locks are much safer than ordinary locks. Ordinary locks can be removed from the side with a hard plastic sheet. Smart locks rely on pre-set programs and passwords. This cannot be overcome by external temporary forces. In addition, the super convenience brought by smart locks is needless to say. The popularization and application of smart locks is a necessity for social progressHowever, whether you like it or not, in the near future, your home will eventually install smart door locks. However, do you really dare to choose and install smart door locks with hundreds of yuan?

In order to save hundreds of dollars, some friends buy a so-called cost-effective smart lock.
