Electronic door locks have attracted wide attention since their inception, and this new type of product that does not require a key, as long as it can be opened with a password, fingerprint, IC card and even brushing face, has now become the first choice for more and more people when buying door locks. However, while providing convenience for everyone, is the product safety and safety of use really guaranteed?
What about electronic door locks?
In the past 3 years, the Shanghai Municipal Bureau of Market Supervision has continuously tracked the product quality supervision and random inspection results of online e-commerce platform sales, offline physical sales and electronic door lock products in the production field, showing that a total of 61 random inspection batches, a total of 11 unqualified batches, unqualified items are mainly anti-vandal alarm function and anti-interference.
The unqualified products found by the supervision and random inspection have been handed over to the market supervision department where the sampled producers and sellers are located for handling in accordance with law.
According to the national standard GB 21556-2008 "General Technical Conditions for Lock Safety", when the electronic door lock implements the wrong operation for three consecutive times and the protective mask is damaged by external forces, it should be able to automatically give an audible/optical alarm prompt or alarm signal output. Products with substandard anti-vandal alarm functions will not be able to deter intruders and alert consumers and neighbors.
At present, the latest industry standard "mechanical anti-theft lock" (GA/T 73-2015) also has the following provisions on the anti-destructive function of locks:
As shown in the figure above, Class C represents the highest level of vandalism resistance and the highest level of security for locks.
In autumn and winter, people often open the lock with static electricity, and the electronic door lock with unqualified anti-interference function will cause inconvenience to consumers when opening the lock function with fingerprints, and the door lock may fail and people are locked outside the door.
The safety protection design of the electronic door lock has two aspects: the protection and safety of the mechanical design part, mainly focusing on the level of the lock cylinder, it is best to choose the highest level C level.
The protection and safety of the electronic circuit design part is to see that it has an anti-vandal alarm function (the anti-pry alarm switch/device is generally on the back of the front panel of the electronic door lock).
Virtual bit password technology means that consumers can add any string of numbers before entering the correct password, without worrying about password leakage.
For example, the correct password is 123456, you can enter the password like this: (8)(6)(7)123456(0)(2)(3), and the number in parentheses can be any number.
Some consumers will worry about their fingerprints being extracted, in fact, it is not easy to extract a complete fingerprint on the fingerprint lock.
At present, there are two kinds of mainstream fingerprint recognition technologies: optical fingerprint recognition and semiconductor fingerprint recognition (biological living fingerprint recognition).
It is best to choose an electronic door lock using semiconductor fingerprint recognition (bio-living fingerprint recognition) technology for higher security.
Single-machine electronic door locks can usually be unlocked by access control cards, digital passwords, fingerprints, etc., while networked electronic door locks can also unlock remotely for others in addition to the above functions, and set the key information for specific personnel to use time limits.
Networked electronic door locks are more powerful, but consumers should pay more attention to network security and avoid accessing networks with low security indexes.
The lock cylinder class is C and the safety function with anti-vandal alarm function is the best.
It is not easy to leak passwords with false bit cipher technology.
Semiconductor fingerprint recognition is more secure than optical fingerprint recognition.
Networked electronic door locks require attention to network security.
