The vice president of China Lock Industry Association has made a detailed analysis of the different functions, advantages and disadvantages of various locks. Consumers can also be used as a reference when buying, beware of buying unsuitable products.
The first, the latest technology: face lock
The face lock is an electronic lock that uses the face recognition system as a means of identifying and authenticating. The difference between it and the fingerprint lock is to turn the fingerprint recognition module into a more advanced face recognition module. The face recognition module is a 3-dimensional recognition mechanism based on infrared thermal sensation. There is basically no possibility of being copied, whether it is HD photos, 3D printing or even twins can be accurately distinguished. And because the algorithm of the face recognition system has higher precision requirements, he is the real "smart" lock on the market with a background system. In simple terms, the difference between him and the ordinary electronic lock, the function machine and the smart machine in the mobile phone. The difference is.
advantage:
1. Infrared camera light captures hot portraits in real time, less than 0.1 seconds, instant intelligent sensor recognition opens and completely liberates hands
2, super accurate identification system, 0.0001% misrecognition rate
3, can not be copied, high security.
4, regardless of the environment and the use of people, regardless of men, women and children, cold, wet, day and night can be used normally.
5, a powerful back-end system, truly intelligent, remote management, centralized management, LAN management, rights management, time management can do.
6, can be docked with the smart home platform.
Disadvantages: high cost, high power consumption, and strong sunlight have a greater impact on recognition.
Price range: 3000-20000, etc. Opening time: 0.1s
Value for money: ★ security level ★ ★ ★ ★ ★ convenience ★ ★ ★ ★ ★ technology degree ★ ★ ★ ★ ★
Overall rating: ★★★★☆
Second, the most common: password lock
The first thing that emerged in the early days of the development of electronic locks was the combination lock, which was an electronic lock product derived from the pain point that people always forget to carry the key and lose the key.
Advantages: no need to carry any door opening equipment, low cost.
Disadvantages: The shortness of the digital string is insufficient, and the long is difficult to remember; the password input process is easy to be peeked or recorded; the opening time is long and the use is cumbersome.
Price range: 200-2000 yuan opening time: 3s or more.
Value for money: ★ ★ ★ ★ security level ★ ★ convenience ★ technology ★
Overall rating: ★★
Third, card lock
The principle of the card lock is to add a card reader on the basis of the mechanical lock. When the card reader reads the correct card information, it issues an unlock signal to unlock. Most of the card locks on the market are IC card readers.
Advantages: easy to open the door; easy to manage; low cost; cards can be extended, such as binding traffic cards, consumer cards, access cards and so on.
Disadvantages: There is no fundamental solution to the pain point of carrying the key; the security level is low, it is easy to be copied; the card is easy to damage; the centralized management depends on the card, and it is impossible to manage in real time and remotely manage.
Price range: 400-2000 yuan, opening time: 1s or so.
Value for money: ★ ★ ★ ★ security level ★ ★ convenience ★ ★ technology ★
Overall rating: ★★★☆
Fourth, fingerprint lock
Fingerprint lock is the mainstay of the current electronic lock home field. It is a combination of biometric technology and traditional lock technology. Most of the fingerprint locks now also integrate the opening method of the aforementioned lock and password lock as a backup opening means.
Advantages: no need to carry any door opening equipment; due to the combination of the original technology of the card lock and password lock, the advantages of the card lock and the combination lock are also integrated; the door opening time is faster.
Disadvantages: very easy to be copied, a tape, an aluminum piece can be quickly copied;
Fingerprints are dusty, dirty, damp, too dry, aging or fingerprints that are not obvious; they are too cold or wet, dry and unrecognizable; low recognition accuracy.
Price range: 1000-10000
Opening time: 1s or so
Value for money: ★ ★ ★ security level ★ ★ ★ convenience ★ ★ ★ ★ technology degree ★ ★ ★ ★
Overall rating: ★★★★
Fifth, Bluetooth lock
Bluetooth lock is a new type of electronic lock that was launched in 2014. The main principle is based on the current high penetration rate of smart phones, installing a specific APP on the mobile phone, and turning on the Bluetooth, connecting the current lock through Bluetooth, and entering if the authentication is passed. Compared with the traditional card lock and password lock, this mode has a relatively large improvement in security level and convenience.
Advantages: high security; no carrying problems; easy to open the door; strong scalability, can support cloud home, smart home, Internet of things and so on.
Disadvantages: Due to the problem of Bluetooth communication protocol, it takes a time to realize data communication. This time is less than 1s, and the long time is about 5s. The customer experience is very poor; it is easy to be disturbed and hindered. Unstable; it is impossible to distinguish whether the connected mobile phone is inside or outside the house, which is a potential safety hazard.
Price range: 500-3000 opening time: opening the door for 0.1s (but the connection time is unstable)
Value for money: ★ ★ ★ security level ★ ★ ★ convenience ★ ★ ★ ★ technology degree ★ ★ ★ ★ ★
Overall rating: ★★★☆
Of course, there are some such as iris locks, vein locks, and voice-activated locks on the market. Due to the fact that there are some hard defects in the actual operation or huge cost, they will not be analyzed in detail here.
In general, smart electronic locks are now booming, but there is currently a lack of revolutionary products that combine technology, experience, and price/performance. If you want to make great progress on the basis of these original products, the fingerprint lock should increase the security and experience on the basis of stable cost performance; the face lock needs to work hard to reduce the cost and power consumption; as for the Bluetooth lock It may take more effort to distinguish between inside and outside the door and change the communication protocol.
In this era of rapid technological development, single security or aesthetics can no longer meet people's needs. A product that is beautiful, convenient, and safe is the direction that the door lock industry needs to work hard and the user's pursuit of high-quality life. I look forward to the birth of the Iphone in China's electronic lock industry.
