In 2019, CCTV\’s \”Weekly Quality Report\” column reported on the safety of electronic locks Problem – Easily cracked by small black boxes. Now, three years later, it’s here again!
On August 7, CCTV\’s \”Weekly The \”Quality Report\” column once again reported the evaluation results of electronic locks:The flame retardant and anti-vandal alarm functions have safety hazards.
So what does this mean? Let me tell you slowly.
1. The flame retardant function has safety hazards
The so-called resistanceThe fire function means that the door lock must be able to be used normally in high temperature environments, so that even if a fire occurs unexpectedly in the home, the door lock can be opened smoothly, allowing users to escape quickly.
2. Anti-vandal alarm function There are security risks
The so-called anti-vandal alarm function is often referred to as an anti-pry alarm. When criminals attempt to violently pick the lock, the door lock must be able to sound an alarm in time to deter the criminals.
It is understood that, The cost of the anti-pry alarm function is very low. If the quantity is large, the cost may be less than 1 yuan, but even so, there are still many door locks that do not have this function. Why is this? The answer is profit.
According to the person in charge of the testing agency, many The price of door locks is very low, and the profit may only be ten or twenty yuan, so if you subtract the \”anti-pry alarm\” yuan, you will have a very considerable profit when you add it up.
In addition, the anti-pry alarm function is very useful in daily life. bornIn-life usage is indeed rare and has little impact on actual use, so I guess this is the main reason why many products do not add this function.
CCTV roll call It will definitely make the smart door lock industry more standardized, which will definitely bring many benefits to our user group.
So, as consumers, we should What aspects should be used to judge the quality of a door lock? How to choose a high-quality and reliable smart door lock?
