What are the key points for choosing fingerprint door locks？
1. Is the smart lock safe?
In many film and television dramas that solve crimes or suspense, the protagonist often relies on breathing or smearing special things to obtain the password, so it may give the impression that the fingerprint lock is not very safe. In fact, the fingerprint lock is a combination of "mechanical lock + electronic". It means that the fingerprint lock is developed on the basis of the mechanical lock. The mechanical part is basically the same as the mechanical lock. The C-level lock cylinder, lock body, mechanical key, etc. are basically the same, so in terms of anti-technical opening In fact, the two are evenly matched.
The real smart lock password is at least six digits or four digits, and there are tens of thousands of permutations and combinations. At the same time, the fingerprint lock has a virtual password function, which can be entered in the form of any number + password + any number, which can prevent peeping. Anti-cracking is not so easy to crack at all.
At the same time, most smart locks have networking functions, so they have functions such as anti-prying alarms and real-time viewing of door lock dynamics by users, which are better than mechanical locks in terms of security.
Safe to use
At present, there are also visual smart locks on the market. Users can not only monitor the door dynamics in real time through their mobile phones, but also use remote video calls and remote unlocking by video. On the whole, smart locks are much better than mechanical locks in terms of security. The smart lock uses biometric technology. We all know that fingerprints are the physiological characteristics of the human body and are unique in that they are irreplaceable and reproducible. The biometric technology needs to sense the temperature, texture, blood flow and other physiological characteristics of the finger. It is difficult to replicate fingerprints with existing technological means. When buying, you must look for this biometric technology. Not all smart locks have biometrics. According to the industry standard of "Mechanical Anti-theft Lock" promulgated and implemented in 1994, our country is still unable to meet the current demand for security. Therefore, some high-end smart lock brands apply for the highest level of ANSI certification in the United States for locks. The highest level of quality certification in the world, a smart lock with this certification can guarantee its safety and high quality.
System Intelligence
The initial user can independently add or delete user information when using it. For example, to enter the fingerprint of the family member, he only needs to input the fingerprint and password information of the other party into the system; otherwise, he does not want to let someone directly enter, and delete his or her in the system directly. Relevant information is fine. This eliminates the need to frequently replace keys or even lock cylinders, which saves time and costs.
Convenient
You don’t have to worry about forgetting to bring the key or losing the key, and you don’t have to worry about holding something in your hand and taking out the key and not aiming at the door lock for a long time. Moreover, the current smart lock can also open the door through the mobile phone APP, so that friends who come to visit but happen to be no one at home can also enter the house and wait for the homeowner to come back. The mobile phone can also check the situation outside the house, which is convenient and safe.
For high-quality locks and brands, they have strict quality control of the various electronic devices of smart locks, and basically there will be no such stuck situation. Of course, it is not ruled out that some black-hearted manufacturers overcharge, cut corners and cut corners, causing frequent door locks to jam. Therefore, more attention should be paid to the choice of smart lock brands and products.
2. Is the smart lock expensive? What price smart lock is good?
When many users buy fingerprint locks, price is often one of the factors that they consider. What makes consumers a headache is that the fingerprint locks of hundreds of dollars and the fingerprint locks of thousands of dollars on the market are not in terms of appearance and function. There is not much difference, so I don't know how to choose.
In fact, the price of a qualified and safe smart lock is at least around 150usd, so it is not recommended to buy a smart lock of 20-40usd. One is that the quality is not guaranteed, and the other is that the after-sales The smart lock of 20-40usd contains the profit of the merchant, the transportation cost, and the labor cost. When these are all reduced, the quality of the product itself will also be compressed. It is recommended to buy a smart lock of more than 150usd, if you are not short of money, you can choose a more high-end smart lock product.
The following are some points that need to be paid attention to when purchasing:
（C-Grade Lock , if someone came to steal, it took 270 minutes to open the door）
Although most people now choose C-level lock cylinders, it is not ruled out that some unscrupulous merchants and consumers are laymen who have not done their homework and use B-level locks to perfuse you.
2. Choose the fingerprint recognition method of semiconductor recognition
Compared with the way most companies rely on optical identification of fingerprints at work, semiconductor identification can not only identify whether the fingerprint pattern is consistent, but also sense specific biological characteristics such as finger temperature and capacitance, so you are not afraid of others holding it. Copy the fingerprint to unlock it.
Moreover, semiconductor fingerprint recognition has a certain tolerance for fingerprint incompleteness-even if the finger is accidentally injured, the automatic AGC circuit can be activated to repair the fingerprint, so that the wound on the finger will not affect the fingerprint recognition unlocking. This is something that optical fingerprint recognition cannot do.
3. Can it prevent small black box attacks?
The small black box is the black technology that can crack the system. By generating strong current pulses, it attacks the smart lock control system and uses electromagnetic fields to interfere with the circuit to make the lock body open automatically. Some miscellaneous brands with incomplete information will be attacked and cracked, while regular brand-qualified products generally will not.
When buying a smart lock, you must buy a lock with anti-small black box unlocking, anti-static, anti-electromagnetic interference, so that your home has an extra security.
4. Is the after-sales service in place?
In the same way, you get what you pay for. Some low-quality and low-cost Sanwu products save a short time. If you can't get convenience and peace of mind, you may face quality problems and problems that cannot be timely after-sales. Therefore, it is necessary to choose reliable products.
According to the above-mentioned requirements, I would like to recommend several popular products in our ONE-LOCK Electronic Co LTD, including fingerprint locks with high cost performance. You can refer to them when purchasing.
