From the perspective of function usage, fingerprint lock applications are fingerprint lock, password lock, card lock, and mechanical lock, including these four categories, and then the appearance is different. However, the quick opening tool only opens a locking tool for anti-theft doors within 1 minute. But this tool is very fast. 100 visits cannot be completed within 1 - 10 minutes. Therefore, today's thieves are basically stealing with this tool, sweeping the building, with fingerprint lock of the Super B lock core, which guarantees the safety performance and increases the value of fingerprint lock everywhere, under the luck of thieves, street-sweeping theft can avoid losses.
At present, fingerprint lock is divided into three levels: a, B and c. The three levels are divided into anti-technology opening duration, and a is anti-technology opening duration of 1 minute; B is 5 minutes; c is 10 minutes. Don't underestimate these minutes. According to the investigation of the Ministry of Public Security, as long as you can't unlock the lock for 1 minute, the 90 ° thief will stop. Therefore, it is necessary to select a lock above level c, and the longer the prevention technology is opened, the better it is, so as to prevent thieves.
People are inert and habitual. Thieves also like to do skilled work. At the same time, there are mechanical lock and fingerprint lock. They must choose mechanical lock. Now more and more consumers, buying fingerprint lock is the first choice for domestic brands, because countless users add a fake mortise lock behind the panel to reflect the regret of buying foreign brands, so what else are we talking about?
The fundamental purpose of manufacturing fingerprint lock is to solve the problems of low number of master key keys used by thieves in the usual mechanical lock, high mutual opening rate and poor technical unlocking performance, so as to improve the safety performance of locks.
This is about fingerprint lock. Can the thief open it? Fingerprint Lock can prevent thieves from breaking into houses more than mechanical lock. It is common to see that mechanical lock is easy to open, but it takes time and complexity to open fingerprint lock. If thieves really want to steal, they can only choose to climb the window, it is too difficult for thieves to calculate the time cost and risk factors.
Now countless families use fingerprint lock, combination locks and even face recognition locks, does it mean that the mechanical lock cylinder cannot be pried through technical unlocking?
A senior engineer who specializes in manufacturing smart lock in hangzhou and is responsible for the research and development of locks said that in fact, fingerprint lock of the mechanical lock on the market are equipped with spare keyhole. This is to do this when fingerprint lock is out of power or failure, the user can use the spare mechanical key to open the door lock, but in this way, if the spare fingerprint lock of the mechanical lock is pried through the technical unlocking, then the anti-theft function of the fingerprint lock itself is meaningless.
The key point of anti-theft is-lock cylinder
Pay attention to the instructions when buying fingerprint lock
At present, our country divides the lock cylinder standard of anti-theft door into three levels, namely: Class A, anti-technical opening time is more than 1 minute; Class B, anti-technical opening time is more than 5 minutes; super B (also known as C), anti-technical open time is more than 260 minutes.
Three levels of locks, A- level locks are the cheapest, the price is below 50 yuan, while the price of B- level locks ranges from 50 yuan to 100 yuan, exceeding B, the price range of class C lock is relatively large, the cheaper one is more than 100 yuan, and the more expensive one is 500 or 600 yuan.
Fingerprint Lock. What level of lock cylinder is installed in the spare machine keyhole of password lock and face recognition lock is very important.
More and more families have bought fingerprint lock in the past two years. Senior engineers said that consumers only pay attention to the convenience and safety of fingerprint lock when buying fingerprint lock, often ignoring whether the spare mechanical lock is safe and sound, for example, while pursuing high technology, some manufacturers make fingerprint lock high-end, but the spare mechanical lock uses the lowest grade a lock, which gives criminals a chance.
When purchasing fingerprint lock, you should pay special attention to the level of spare mechanical lock, which will be marked in the manual. Most of the smart lock produced by ordinary domestic mainstream factories use the most secure Super B lock core.
The police said that for criminals, the essence of security lock is "delay time". The more time criminals spend on locks, the easier they will be found, and the greater their psychological pressure during theft. The police suggest that you can install monitoring at home if necessary, which can more effectively deter criminals. At the same time, you should not store a large amount of cash jewelry at home, and whether you are at home or not, you 'd better lock the door back, after the anti-theft door is locked, it will increase the difficulty and time of unlocking, which is the most economical and simplest anti-theft method.
