With the continuous improvement and maturity of smart locks, they are rapidly moving towards ordinary families, which can solve the problem that people are inconvenient to bring keys, and can facilitate people's daily use through fingerprints, passwords and cards. Don't worry about losing your keys, forgetting to bring your keys, and accidentally closing the door when you go out temporarily.
So what is its principle and whether it is safe? Let's analyze it for everyone.
① Interference of Tesla coil
When smart locks were just popularized, there was a rumor that smart locks could be opened in 3 seconds with a small black box. In fact, this little black box is a Tesla coil, which belongs to the electromagnetic pulse (EMP) jammer. It can release electromagnetic pulse signals and interfere with chips and circuits in digital and electronic products, resulting in garbled codes, errors, crashes and damages. , so as to achieve the effect of unlocking.
However, with the development of technology and the maturity of industry standards, this test has been included in the industry standards. As long as it is a smart door lock tested by a regular brand, it can resist the interference of Tesla coil.
② Cat's eye unlocking
Smart door locks basically have the function of locking with one button, which is to enable users to unlock quickly in use. But for semi-automatic intelligent door locks, this function also has certain risks. Especially if there is a cat's eye on the security door, the bad guys may remove the cat's eye, insert a three-claw device, snap out the indoor door handle and press it to unlock it.
Of course, in order to cope with this situation, many manufacturers have redesigned the handle, that is, it is impossible to unlock the door only by pressing the handle indoors, and it is necessary to press the button or dial the button to unlock the door. The problem of unlocking the cat's eye can be effectively prevented.
This situation only applies to semi-automatic door locks, and fully automatic door locks are not affected.
(3), fingerprint copy unlock
At present, most smart locks on the market have two fingerprint recognition functions, optical recognition and semiconductor recognition. Optical recognition uses the refraction and reflection of light to collect and verify fingerprint information, while semiconductor recognition uses the principles of capacitance, electric field, temperature and pressure to collect fingerprint images. From the safety point of view, semiconductor identification is safer, not affected by light and finger humidity, and more accurate.
Theoretically speaking, there is a risk of fingerprint duplication in optical fingerprint identification, but it is proved by experiments that the transparent glue fingerprint extraction method in movies cannot be opened because optical fingerprints need concave and convex surfaces to produce effective image information. Only the 3D fingerprint film I co-created can unlock the lock, so I don't have to worry about using optical fingerprint to identify smart door locks at home.
④ The stalker peeked at the password.
Another situation is that someone peeks at the password to unlock it. The probability of this happening is very low. When you open the door, there will be no strangers around you. What's more, as long as it's not too simple, you can't remember the six-digit password instantly.
Even so, technicians introduced the function of virtual password. As long as the middle digit is kept correct and the same digits are randomly input before and after, the password length can be randomly extended and the memory difficulty is increased.
Therefore, the brand smart door lock technology produced by regular manufacturers in the market is quite mature. Ordinary fingerprints, passwords, credit cards, emergency keys, etc. You can use it safely, and there are more advanced door lock opening technologies, such as face recognition, iris recognition and vein recognition. It is more convenient and safer than the traditional mechanical door lock. Feel free to use it, but remember not to buy inferior products.
At present, the smart lock technology is very mature and easy to use. You don't need to take your key when you go out. When choosing a fingerprint lock, you must choose a semiconductor fingerprint head and a zinc alloy shell. Take the mechanical key to open the door to prevent failure.
If you don't blindly pursue big brands, in fact, some companies are doing well. My home is decorated with the fingerprint lock of Guangdong Yabao Lowe. Not only can the cat's eye unlock the lock remotely, but it can also have a remote video conversation, and the factory direct price is also affordable.
Yabao Lowe Smart Lock is a multinational high-tech enterprise that develops, manufactures and sells smart locks. Since its establishment in 2008, Yabao Lowe has focused on the field of smart fingerprint locks, adhered to the development model of "focusing on users, focusing on technology, focusing on quality and improving after-sales", and determined to build a high-end brand in the field of smart locks.
At present, Yabao Rottweiler has two independent R&D teams: Appearance, Module and Lock Structure. In terms of appearance and structure, Yabao Rottweiler has several teams of engineers with more than ten years of design experience, making every detail that can enhance the user experience to the extreme. Yabao Lowe smart fingerprint lock has its own patents from appearance to structure, and has obtained national appearance patents, utility models and invention patents exceeding 100. Apotheway's innovation is not only reflected in research and development, but also in every link of production and operation. Making products well has always been the belief of Apotheway. Yabao Lowe fingerprint lock strictly follows the high standards of the industry in terms of functionality, practicality and even reliability. Yabao Lowe fingerprint lock machine passed 25 quality tests, and the lock core passed 30,000 reliability tests. Let the firmness of the whole lock body go to a new level.
Their service is in place and the installer is very careful. Once there was no electricity, he came to the house for free. They are also one of the top ten smart lock brands in Guangdong.
They can also recycle old locks and save some money. Fingerprint lock adopts intelligent anti-theft chip and super-C lock core, which is different from the traditional reproducible optical fingerprint head.
: Guangdong's top ten brands Yabao Lowe smart locks also solemnly promise: three-year warranty, only change without repair! If there is any quality problem, change the lock directly for free!
Installing a smart lock saves the trouble of getting the key. You can look at the smart lock of 360 and go to the mall of 360 to find out.
Smart lock home 360, cost-effective. I suggest you go to 360 Mall.
