In recent years, the market of fingerprint locks is extremely hot, and various brands and manufacturers have launched fingerprint locks covering all kinds of prices and styles, ranging from 3,000 to 4,000 for Yale Samsung and 3,000 to 5,000 for various manufacturers of miscellaneous brands, especially the black box incident that once broke out, which pushed the fingerprint lock to the forefront. Due to the complexity of various manufacturers and brands, the mixed fingerprint lock market made it even more difficult for many users to choose, making people really don’t know how to do it. I really didn’t know about it. I found it that day when I looked at the trial center. What I didn’t expect was that Bosch, an established enterprise in the home appliance industry, also began to enter the fingerprint lock industry. Mainly the big items at home, such as refrigerators and washing machines, and the small wiper, spark plug and brake oil for cars are all made by Bosch. After years of use, the quality is very reliable, and I still have a strange affection for this brand.
This time, I saw a trial and tried to apply for a lucky draw. After repeatedly determining a series of indicators such as the thickness of the door, the width and length of the lock core, and the opening direction of the door, I quickly got it. After the installation, it has been used for a period of time, and the detailed evaluation is brought below. After opening the two-layer package, you can see that the whole lock is exquisite in workmanship, and the overall design is very simple and atmospheric. The panel painted like a piano is shiny, and the hand feel is still heavy. The inner and outer handles should be made of materials similar to aluminum alloy, and the materials of the whole lock are still sufficient. The cushion leather pad has no burrs and irregularities. Spread all the accessories evenly, including the inner and outer handles of the fingerprint lock, the lock catch plate, the lock body, the screw fittings, the 4th battery, 2 mechanical keys, 2 IC door cards, installation opening drawings and instructions. The inner and outer panels are ultra-thin and basically minimalist, which gives me a very good first impression.
Fingerprint lock, as the name implies, one of the core parts of the whole lock is this fingerprint head. According to the publicity materials, the fingerprint head of this lock adopts a semiconductor fingerprint sensor, which can be opened at any angle of 360. After testing, fingerprints can be recognized normally at any angle. Usually, the fingerprint head will not light up. When the finger is sensed to be unlocked, colored lights will light up around the fingerprint head, which still looks cool. The fingerprint head is designed at the handle, so it is convenient to turn the handle down to open the door when unlocking. It seems that this design is very popular recently. Different from other manufacturers, the fingerprint head of Bosch fingerprint lock is designed with an inclined plane. In the actual use process, the thumb can be placed in the fingerprint recognition area by "holding posture" naturally, and the inclined plane of the fingerprint head fits the curve of the thumb very well, so that when the whole door opener is held at the handle of the door lock, it can be in a very comfortable unlocking and door opening interface, and it is only necessary to press the handle after recognition, and it is not necessary to press the fingerprint recognition separately before unlocking. Moreover, the design of the inclined plane of the fingerprint head can also avoid the wear caused by the collision and friction between the fingerprint head and the wall to a certain extent. Such a small design is still very practical and intimate.
Let’s take a look at the local details. Here are the keyboard input area and IC card sensing area of the door lock, which will not light up at ordinary times, and will only light up when touched. Like all products on the market, Bosch fingerprint lock also supports false password function, which avoids password leakage caused by installation monitoring by outsiders or neighbors. At the same time, Bosch fingerprint lock adopts anti-theft alarm function. When fingerprint unlocking or password input fails or is wrong for more than 3 times, the system will lock and alarm, and it will take 3 minutes to continue operation. When the mechanical key is used to unlock the lock, it will also trigger an alarm, which increases the overall security to a certain extent. However, the slight flaw is that the IC card’s sensing is not very sensitive, the response speed is slow, and the sensing range is limited. Basically, it is necessary to stick the card on the sensing area, and it will take a few seconds to prompt that it has been unlocked. At the same time, I personally feel that there are two small functions that are very intimate. One is that when the door is unlocked, it will automatically lock after a few seconds. The other is that when the door is detected to be in an unclosed state, there will be a tinkling sound, which is a very intimate reminder function.
The inner handle integrates the child lock function and the anti-lock function. When the child lock function is turned on, the inner handle can’t be turned, and the door can’t be opened naturally, which can prevent the child from opening the door and running out to some extent. Different from other manufacturers, the anti-lock function of this fingerprint lock is independent of the door lock function, and the anti-lock function of many manufacturers is linked with the door lock, even after the door is locked by fingerprint or password, the anti-lock function is simultaneously linked and opened. Because the anti-lock function of Bosch fingerprint lock is independent, it can be locked mechanically by lifting the handle and rotating the anti-lock knob at the same time, so even if the thief cracks and opens the fingerprint lock, it needs to physically break the anti-lock function, otherwise the door cannot be opened, adding a layer of insurance.
Like most manufacturers, Bosch smart lock adopts C-class lock core, with three anti-theft locking tongues and one anti-lock locking tongue on the side. According to the investigation data, the lock core of C-class lock adopts the patented key of double row, computer and compound curve groove, and it takes professionals more than 240 minutes to open it. Unfortunately, I confirmed with the seller before delivery that this smart lock can be hung with the hook of heaven and earth, but in the actual installation process, I don’t know why. The installation master told me that the lock body of Bosch smart lock is not the same as the original lock body of the security door. Not only can it not be hung with the hook of heaven and earth, but also the hook of heaven and earth has to be dismantled. Finally, the hook of heaven and earth was violently dismantled with a grinding wheel saw, which shows that there is still room for further improvement in the adaptability of manufacturers to the security door.
The brain of Bosch fingerprint lock adopts cortx-m3 processor, which has high performance, low power consumption and strong stability. According to publicity materials, it has a fingerprint service life of 1 million times and an applicable age of 5-70 years old, and can accommodate 100 fingerprints. In actual use, it feels that the compatibility and recognition rate of fingerprints are still very high. I was worried about this problem before, because many fingerprint locks on the market are not friendly to fingerprint recognition of children and the elderly. Because it is installed in parents’ home, in daily use, the two old people can successfully unlock it once most of the time, and occasionally it takes twice, and the recognition rate is still very good. When the indoor handle panel is opened, it can be seen that there are three prompt sound adjustment buttons and function setting buttons, which control the prompt sound of the smart lock respectively. The first gear is silent, the second gear sound is very weak, and the third gear sound is actually not very loud. In actual use, it is set by everyone. The function button can restore the factory settings and enter the setting function to enter the password fingerprint of the administrator or user.
In fact, the installation service function of fingerprint lock is a common problem. Each manufacturer is considering the cost, and basically does not have its own special installation team. The installation service function of Bosch fingerprint lock is online, provided by a WeChat WeChat official account named Youfubao Online. The principle should also be related in the markets of various installation places. There is a drawback here. If it is a fingerprint lock purchased offline, it is guaranteed after sale. In the daily use process, if there is any problem, you can contact the seller directly, and after sale can be done. However, this kind of fingerprint lock purchased through the e-commerce channel, if there is a problem in the daily use process, must first contact the e-commerce online customer service, and then the customer service will help you contact the maintenance master, which is very inconvenient. I hope it will improve in the future. Throughout the installation process, the master was very careful, but it was very troublesome. It took almost 3 hours to complete the installation. I don’t know if it’s because of the problem of the security door or something. The Panpan brand security door is installed uniformly in the residential property. Except for the disassembly of the heaven and earth hook, the installation holes of the front and rear panels are not matched. The master used a grinding wheel saw to carry out a large-area reaming operation. Although the installation did not affect the appearance, it was impossible to install the original mechanical lock again because of reaming. This goes back to the problem of matching degree, because other manufacturers’ fingerprint locks are installed in the house at home, so I won’t mention the manufacturers here, but for security doors with different lock bodies and different specifications, there are different lock bodies and corresponding front and rear panels. But Bosch’s fingerprint lock, I don’t know whether it’s because of the trial or the fact that it’s relatively simple.At the time of delivery, the seller didn’t confirm with me the brand of the door lock and the type of the lock body. Personally, I feel that the matching degree of Bosch manufacturers for various types of security doors needs to be improved.
At the bottom of the outer panel of the lock body is a USB emergency power jack, a mechanical keyhole and a speaker. As a solution for emergency use of the lock body battery, the emergency power jack is rarely used in daily use. It can be seen that the mechanical key is under the lock body, and Bosch’s smart lock is a fake mortise. I have also read many articles on the Internet about the problem of true and false mortise. Personally, the smart lock is more convenient and comfortable. After all, you don’t need to bring a key when you go out, and you are not afraid of being locked out of the door by throwing garbage downstairs and taking a courier. The security of a lock can be divided into several aspects, namely, technical security and violent security. Technical security means the security degree of the fingerprint head, while violent security, for a thief who is really determined to steal your house, there is not much difference between any fingerprint lock as long as the panel is violently opened. However, which thief dares to make such a big noise to break the lock? The cost of this theft and the risk of being caught are too high. Suppose that even if there is such a bold thief to smash the lock, Bosch fingerprint lock also has an anti-theft alarm system. When someone picks the lock, the fingerprint lock will give an alarm sound to scare off the thief or remind the neighbors. How to put it, different people have different opinions.
Finally, let’s talk about a little flaw. Bosch fingerprint lock adopts a design similar to the piano paint panel. At the same time, it is beautiful and elegant, and the common fault of this kind of design is also inevitable, that is, fingerprints are left behind. Anyone who pays attention to it in daily use will leave traces or fingerprints on the panel, which greatly affects the appearance and needs to be wiped frequently.
