As the third generation of door locks for Chinese door locks, smart locks are also the highest technological crystallization of the current door lock industry. Not only are high-tech products, but also easy to use, they are slowly spreading throughout the country; Chinese family door locks are generally divided into mechanical locks and anti-theft locks. The use of mechanical locks is the most common, and the use of mechanical locks is the most common, because mechanical locks and anti-theft prices are low, the market position is long, accounting for 91.22% of the market share; however, mechanical locks and general anti-theft have fatal drawbacks: no anti-theft. Before the CCTV "Weekly Quality Report", the salespersons of the locks were exposed in the mall, and the anti-theft lock and mechanical lock were opened with tin foil for 5 seconds, which made the reporter instantly shocked!
In fact, the anti-theft lock and the general mechanical lock are not as safe as everyone thinks, because the price of the lock cylinder is directly proportional to the technical content. Tens or even hundreds of yuan of door locks, out cost, freight, sales commission, tax, etc., the real manufacturing costs can be imagined, and the high-grade C-class anti-theft locks are expensive, the average family is difficult to accept. So how to choose a good door lock anti-theft?
Smart lock, also known as smart lock, its intelligent door opening method: intelligent identification, induction, password, key, so that more family door locks are liberated, no need to use heavy and cumbersome keys to go out, just one touch, door lock It can be opened. It greatly facilitates the life of residents and makes travel easier. The smart lock relies on bio-intelligence recognition. Even if the intelligence is copied, it cannot be opened. Biometric recognition is the technology of active smart lock and leather intelligent nerve. smart Lock. Smart locks are expensive, but they are favored by consumers, and the price is generally above 2,000 yuan.
Is it really safe to install the smart lock door?
According to the standards given by the Ministry of Public Security, all smart locks must be mechanically locked at the factory, and the mechanical lock must be outside the door to open the door as a spare. Therefore, smart locks are generally four types of unlocking methods: smart, swipe, password, and key. Both the password and the key are reserved. However, according to the previous CCTV "Weekly Quality Report" program report, the general unlocking master or unlocking expert, using the foil paper to open the lock of the A-class mechanical lock cylinder takes only 1-3 minutes, and it takes only 3-9 minutes to open the B-class anti-theft lock. . Then the question comes. Does it mean that smart locks can be unlocked by thieves without intelligence? The answer is yes.
In such a wave, people who have begun to pull out are complicated by simple things, but there are also other people who want to simplify complicated things. Just like the global radar smart lock, after years of research time, with such a unique, almost paranoid belief, it is the uniqueness, reliability, and security of intelligent technology. It is only for "making a good smart lock." , to make a safer smart lock."
The products of the global radar are very special, because the global radar's understanding of "good" is: perfect application innovation in smart technology, perfect safety and reliability in the product, and perfect humanization and appearance in design. This label is destined to become the brightest color in the future development of global radar. The new concept of security anti-theft smart lock, leading the industry technology, to do smart locks that thieves can not open, to do smart locks at home.
The era of intelligence, at the touch of a hair!
Global Radar Smart Lock creates a new era of intelligent lock intelligent anti-theft in China. Facing the current security risks of intelligent latching, global radar intelligent lock technology innovation, to achieve true intelligent anti-theft: mobile phone remote monitoring, mobile phone remote unlocking, anti-theft alarm, mobile phone reminder And other powerful features. The warning and monitoring function of the global radar intelligent lock makes the thief unable to get close. In addition to the intelligent personnel who can enter the smart, it can be safely unlocked. Other intelligent people will be alerted by the smart lock once they are close to the door lock. If they are forcibly unlocked, they will be forcibly unlocked. Was whistle, photographed, and alarmed. Do not give the thief a chance to approach the door lock at all, and the unlocking technology can only be daunting.
There is no best thing in the world, only better; global radar smart lock is not the best smart lock, but it is a brand that is constantly innovating in intelligent, innovative and secure smart locks, higher and farther. Better is our eternal pursuit. Global radar smart locks don't do the best, just do better!!
