Qunsheng s smart lock has a national 3C certification code, is their product quality stable?

That's for sure, these two models of products have also obtained the national 3C certification, you can go to their store to pick it up, see what style you want, they have it.

How about the group rise security door.

How about the Qunsheng security door? Qunsheng door industry is a subsidiary of Qunsheng Group, the group was founded to the present more than 20 years of history, it is a large group company involving a variety of industries. And Qunsheng Door Industry is just one of its enterprises.

What about the quality of the anti-theft door under the group of door industry? The answer can only be found by looking at the voice of the consumer.

First of all, I want to say that there is a group of top ten brands of anti-theft doors on the Internet, we don't care about its ranking, but since it can be a relatively loud brand in the domestic anti-theft door, it proves that the company is still good, and the product quality should still be okay. There are a lot of reviews on the Internet, both positive and negative, and there are no problems after being useful for a year, and problems occurring after being useful for a month. Of course, I believe that these questions should be true, but this shows that the group of anti-theft doors *** is not good?

Whether the anti-theft door is good or not, in addition to the quality of the door panel, is also related to the quality of the door lock and the quality of service. In some places, the after-sales service is poor or the door lock cannot be opened, and this should also be there. But we can't completely deny that the quality of the anti-theft door is not good.

As far as is understood, the quality of the group lift security door is okay, of course, some of its shortcomings should also be improved.

Shenzhen Holis smart lock is good, and it is safe to use.

As far as I know, Qunsheng FHS-QS-8801 and FHS-QS-8802 fire locks meet the requirements of CNCA-C18-02:2014 and CCCF-HZFH-02, and won the China National Compulsory Product Certification. You can go to Qunsheng to take a look, and they also have a lot of smart lock styles.

I know that Haibeisi smart locks have 3C certification and fire hour certification, and the following are their specific models and certificate numbers, test reports, which can be queried on the China Fire Product Information Network.

I know a friend who works on their side, and their quality inspectors will conduct strict inspections on the locks to ensure that each factory group of smart locks can be used normally and stably.

Their smart locks have also obtained the national 3C certification.

It mainly depends on the brand, and now there are many smart lock brands. The quality is about the same, you have to see whether it is safe, whether it is anti-theft or ornamental to buy a lock.

Suozhong smart lock, the quality is OK, and the appearance is more fashionable.

It's better not to know that brand, I use Van Gle, and I bought it together when I bought the door. Very easy to use and convenient.

In fact, it is still a mature smart lock, I have used a miscellaneous brand, it broke in less than half a year, and now this is a group of sheng, and the elderly and children often come and go at home, no problem.

Common technical standard parameters of fingerprint locks.

1) Average fingerprint matching time test: The requirement of the Ministry of Public Security for security and police detection is that the fingerprint matching time is 3s (1:n,n10).

2) Emergency unlocking function inspection: the Ministry of Public Security testing requirements: special devices specially made by the manufacturer can be used to take special methods for emergency unlocking; When the mechanical emergency opening is adopted, the mechanical lock should meet the requirements of the GA T73-1884 and the middle A level.

3) battery power supply requirements inspection: the Ministry of Public Security security and electronic police standards are: under normal working conditions, the average working current of the fingerprint anti-theft lock should not be more than 500mA; The working current should not be more than 50 A in the dormant state; The battery capacity should be able to ensure that the fingerprint anti-theft lock connection is opened and closed normally for 3000 times without undervoltage alarm indication.

4) Flexibility, size and appearance quality inspection: The requirements of the Ministry of Public Security's security and electronic police detection technology (standard) are: flexible mechanical transmission structure, no jamming, flexible rotation of the handle, and accurate reset; The extension length of the main deadbolt shall not be less than 14mm for grade A and not less than 20mm for grade B; The length of the oblique tongue is not less than 11mm;

5) All metal parts should be treated with surface anti-corrosion, and should meet the requirements of protection rating level 6 after 48 hours of neutral salt spray (NSS).

Of course, product safety does not only depend on the consciousness of manufacturers, but also requires the introduction of corresponding national standards. So far, our country has not yet introduced the national standard for smart locks in the strict sense, and all smart door locks are still in accordance with the original general lock security technical standards.

No, there is no industry standard, and it is estimated that some manufacturers do not have enterprise standards. Smart locks have a low threshold, high profits, and a mixture, so it's best not to use them now.

At present, there is no intelligent technology such as password authentication, face recognition, and fingerprint recognition, which are in the hands of various companies, and have not yet been universalized, but the relevant departments will promote the eventual unified security standards.

There is no domestic standard for the time being, so you can formulate enterprise standards.

1. The standards of each country are different, and the international standard smart lock, no matter how many ways to unlock, must have the function of key unlocking.

2. The difference between international standards and non-standard mainly lies in the requirements of the lock body and the lock cylinder, such as: the distance from the handle to the lock core, the length and width of the gusset, the length and width of the lock body, etc., are determined according to the opening method and door thickness of the door. Most of the United States uses wooden doors, and most of China uses security doors.

3. The difference between international and non-standard smart locks and mechanical locks is almost the same, but several unlocking methods have been added on the basis of mechanical locks.

Europe, America, Japan and South Korea have relatively mature home security markets, with relatively complete and strict national standards, and unified regulations on the size of smart locks, lock cylinders, lock bodies, etc. China's smart locks have a number of national standards and industry standards, but there are many gaps in the content of national standards and specifications, and they are concentrated in the field of public and building standards, and the industry standards are quite messy.

At present, there is no standard reference basis for enterprises in the production and design process, and the confusion of standards leads to uneven product quality levels. If products can be manufactured under unified standards, the interests of consumers are ultimately protected. Some small and medium-sized manufacturers in the industry due to cost, technology, design and other reasons, can not strictly implement the standards, in the security, R & D management, quality management, business management and other aspects of the lack of experience and management and control capabilities, can only rely on low quality and low price impact market, the development of the smart lock industry and the popularity of the application has a huge negative impact.

In order to avoid bad money driving out good money, make scientific competition among peers, and promote the survival of the fittest of enterprises in the industry, it is urgent to speed up the construction of standards at the national level.

No The market is chaotic at the moment.

There should be! This kind of industry should have a unified standard, no rules are not a circle, it is recommended to have a unified industry standard, so it is good.

At present, there are the following categories of smart door locks: 1. Fingerprint locks, which are fingerprint locks, backup machinery, etc., which are mainly for convenient door opening and anti-theft functions.

Anjia's full range of entrance security doors abandon the traditional key lock system and adopt human dynamic sensing technology with high security and confidentiality.

With the continuous upgrading of theft technology, the traditional key lock system due to its own defects, can not avoid the easy replication and easy operation of metal products, electronic products and other characteristics, there is still the possibility of being opened by skills, therefore, Anjia intelligent security door resolutely resists the use of key lock systems with security risks.

With its profound skills and new scientific research achievements, Anjia has independently developed remote sensing skills, portrait recognition, fingerprint recognition, iris recognition and other security technology systems, bringing the entrance security door to a new security height. Anjia uses new biological science and technology to make the entrance security door have the ability to isolate all technical theft, and has obtained a number of national patents.

Yale, Yale electronic locks are one of the oldest international brands in the world and one of the most prestigious brands in the lock industry. The history of Yale not only marks a major innovation in the evolution of Yale locks, but also a microcosm of the development of the entire lock industry. Wait a minute.

Yes, I don't know if you have used a Jinzhidun smart lock called Tianyi, the security index is not a little high, you can go to the official website to learn about it, and there are many technical breakthroughs.

Sunsight smart locks will go through 100,000 unlocking tests before leaving the factory, and have a three-year warranty. Our company was established in 2003 to the present, we have no sales department, only customer service department, many customers are because of the quality of peers is not good and turned over. If the quality is not good, the company will not be able to open for ten years, and it is impossible to achieve the current sales of more than 70 million yuan and the scale of 5,000 square meters of factory.

There are two sides to everything, fingerprint locks are difficult to crack relative to the key, but now fingerprint locks have a common problem, that is, all fingerprint locks are not confident, there will be a keyhole, that is, the fingerprint lock is reliable or not depends on the key there, the key is reliable.

The brand is high, and as the saying goes, you get what you pay for.

Brother Hua red envelope sends red envelope and sends red envelope.

I don't know if you want expensive or cheap.

God's quiz has too many regrets, miss.

The quality of smart locks of Xiaomi Mijia, Luke, Kadis, EZVIZ Network, and Haier is reliable, and it is very good.
