Fingerprint lock as a pioneer of modern home security products, due to the late development, has not reached a very mature period, product standards are not unified, there is not too much experience and standard for everyone to refer to in the purchase, so we feel very troubled when the purchase, how to do?
Fingerprint lock production materials are mainly three kinds, are plastic, zinc alloy, stainless steel. Among them, plastic durability, fire, explosion-proof performance worst, zinc alloy second, stainless steel best. Can be based on the principle of "a look two knock three to choose: (a) Look: look at the appearance. The three materials of fingerprint lock in the appearance of almost no big difference, but there are differences; Plastic fingerprint lock is generally smooth surface, bright color, and zinc alloy is slightly rough and sub-color, stainless steel is the most rough and sub-color. (two) knock: if it is difficult to "see" the fingerprint lock material, we can use "knock" to judge. With finger gently knock on the side of the lock body (positive artifacts due to different materials such as touch screen is bad judgment), if the sound turbidity is not clear or relatively empty, that is likely to be plastic products, stainless steel fingerprint lock percussion sound more sharp focus, not much sense of diffusion and penetration is better, and zinc alloy, between given voice no sharp stainless steel, But compare plastic product pure and fresh anacreontic a lot. Weigh (3) : if you still can't determine the stand or fall of fingerprint lock material, you can use one of the most simple method, that is "benchmark", we all know that the three kinds of material which is light or heavy, plastic lock is very sufficient even internal component with zinc alloy or stainless steel will still exist certain differences, so ok one weigh in hand. Buy fingerprint lock, besides want to see lock body, insert core also is a very important part, see insert core can set out from three aspects: the material that sees insert core, 2 see insert core lock point, 3 see insert core function. (a) look at the material: the core of the material and shell is divided into plastic, alloy, stainless steel three. Because the core is placed in the door, so many enterprises on the core material is more casual, using alloy or plastic, such core is not only weak violence resistance, but also very weak fire performance, is not conducive to safety. Consumers in the choice of the best choice of stainless steel plug, fire explosion-proof anti-skid performance is good. The selection method is the same as the shell selection "look at two knock three." (2) Look at the locking point: the locking point of the fingerprint lock plug is mainly divided into single tongue and multiple locking points. The safety of single tongue lock core is worse than that of many lock points, and the performance of anti-pry explosion-proof is also poor. It is generally used more in foreign developed countries, Japan and South Korea and other regions, and is not suitable for the complex security environment in China. Therefore, it is recommended that domestic consumers choose the multi-lock core with explosion-proof and anti-skid performance when choosing fingerprint lock. (3) Look at the functions: the inserts on the market are generally divided into hotel lock inserts, upper lifting inserts, automatic ejection inserts and multi-lock points self-elastic inserts. Hotel lock core available card pry open, poor safety performance; The use of lift plug, when closing the door need to lift the handle to lock the door, easy to make people forget to lock, not in line with the use of consumers; The big tongue automatically pops out and inserts the core, which solves the shortcoming of lifting and inserting the core, but still can not automatically control the heaven and earth bar; The fourth generation lock body multi-lock point self-cartridge cartridge is the most superior plug so far, the strongest anti-theft function, the most convenient to use. The "trial function" refers to the reaction speed and accuracy of fingerprint lock fingerprint unlock, password unlock and magnetic card unlock. First of all, take a fingerprint and observe the difficulty of the clerk's fingerprint input. If a fingerprint input cannot be identified for many times, it can almost be judged that the fingerprint lock resolution is not high, because the higher the resolution, the more accurate identification, the faster the response, the better the security. After the fingerprint is recorded, the fingerprint lock is randomly tested on the identification and response speed of the correct fingerprint. If the fingerprint is opened immediately after pointing, its response speed is fast, otherwise it is slow. It is best to test several times, only a few times to better identify the pros and cons. Second, test the magnetic card and password unlock. Magnetic card unlocking is the same as fingerprint unlocking, which is also to test the reaction speed and accuracy. Authorized magnetic cards and unauthorized magnetic cards are respectively tested in the magnetic card area to see the reaction and identification of the lock to the magnetic card. The faster the reaction speed, the higher the technical content, and the higher the accuracy, the higher the security. The above is the knowledge to share with you today, in the purchase of fingerprint lock, in addition to look at the quality of the lock, function, installation services and after-sales service is equally important, because fingerprint lock is a high-tech product, need to be installed by professional and technical personnel to normal use, the use of problems also need to be dealt with, So in the purchase must ask clearly relevant installation after sale service; At the same time also need to choose according to their own decoration style. |
