Smart door locks were available about a decade ago. But it has only been used in some high-end residential applications. With the development of technology, the cost has dropped drastically, and it has gradually entered the ordinary home.
Early domestic smart door locks mainly include foreign brands such as Samsung, which are expensive, costing five or six thousand yuan, lacking after-sales service outlets, technical support is not in place, and compared with domestic conditions, the anti-theft function is not good enough, so the application is compared. less.
The smart door lock was installed at home, and the home door was opened with just a finger press. The convenience and comfort brought to us have been loved by everyone. So, are we safe to use smart door locks?
The intelligent door lock is to add the fingerprint unlocking function to the technology of the original mechanical lock. The main technology of the fingerprint unlocking is to store the fingerprint information of the user first. When the user uses the fingerprint to verify, the fingerprint identification system will put the user's fingerprint and the stored fingerprint. In contrast, if the verified fingerprint matches the pre-stored fingerprint, the door lock will open. If it does not match, an error will be indicated and the door lock will not open.
The optical fingerprint head uses light scanning, the information obtained by light reflection recognizes the fingerprint, and the fingerprint shape structure is recognized to obtain fingerprint information; if the criminal wants to fake the master's fingerprint to open the door, then he must obtain the fingerprint of the owner, and also have High-precision modeling equipment. Then, as the owner of the house, are you worried that your fingerprints will be stolen by criminals in teacups, purses, handbags, etc. You don’t need to worry about it, because even in teacups, purses, and handbags. Your fingerprints must be read using very high-precision instruments to read them. High-precision instruments like this are only available to the public security department.
The semiconductor fingerprint head uses a capacitive read-in system to form fingerprint information by using the fingerprint's groove, åµ´ (including the epidermis and dermis layers) and the capacitance change between the read-in surfaces; if the criminal wants to forge the owner's fingerprint to open the door, not only needs to be obtained The master's fingerprint, but also to fake objects similar to creatures, the difficulty of forgery is higher than the optical fingerprint head.
Both types of fingerprint heads can correctly identify the owner's fingerprints, and each has a higher security level. The difference is that the former type of cost is cheaper, the latter type of cost is much more expensive, and the average category can be used by ordinary households and businesses. One type can be used in important departments such as banks and treasury, but more and more smart door lock manufacturers are also using semiconductor fingerprint heads.
The intelligent door lock is upgraded by the mechanical lock. Its main purpose is to improve the convenience of our lives in the case of securing property. Compared with the mechanical lock, the smart door lock is one level higher, and the criminals want it. The fake fingerprint of the forged master is hundreds of times more difficult than the shackle.
Using smart door locks is safer, more convenient, and more comfortable than using mechanical locks. Everyone can use it with confidence!
In recent years, domestic manufacturers have followed up and have come out with many smart door lock products with better quality and stronger functions. The price is more close to the people, and the market acceptance is even higher. There are roughly a few such smart door locks currently on the market:
First, low-priced products: refers to the thousand yuan level, as low as five or six hundred, as high as one thousand wishes. Basically, the locks of these products are used in general, and the security is not much better than the original anti-theft locks of your home. But with the addition of fingerprint unlocking, it will attract some cheap consumers. However, the stability of these locks is not stable enough. Many of these smart door locks will fail in a few days, so it is not recommended to buy such a cheap lock because the wool is on the sheep.
The price of the second or second thousand to four thousand yuan, this price range is the mainstream of the current market, the overall performance is more reliable. It can also meet the needs of most users. For regular household use, it is recommended to choose the right product for this grade.
Third, high-priced products: roughly refers to more than four thousand, to five thousand. In addition to some high-end models in domestic brands, this type of product is a variety of international brands. However, it is full of fake foreign devils, it is recommended to see clearly. Personally believe that the domestic technology and technology, the creation of locks, no need for foreign brands, the warranty is more convenient after sale, and the lock of the national product is more suitable for China's market than the lock of the foreign brand, or choose the reliable domestic locks.
Functionally, each family is almost the same, fingerprint unlocking, password unlocking, IC card unlocking, traditional key unlocking, have become standard. But now in the era of smart home, more and more smart door locks are equipped with mobile APP networking, which can easily control the emergency door lock, and can also control the whole smart home and smart door lock through APP.
In addition, remind friends that with smart door locks, be sure to store the mechanical keys in a reliable location near your home for emergency use. Any electronic device is reliable and there is always the possibility of failure. In case the fingerprint, password, and IC card of the entire smart door lock are opened, it is invalid. At the very least, you have one of the most traditional methods: open the door with a key, at least not destroy the lock. So don't put the matching keys at home. You can put the office, you can also put your parents, and there is a good way: put it in your usual car.
