The evolution history of locks shows that the earliest wooden locks have a history of 5000 years. In the 1840s and 1970s, locks entered the era of mechanical locks and electronic locks respectively. Around 2010, locks entered the era of intelligent locks.

In the era of the coexistence of intelligent locks, electronic locks and mechanical locks, there seems to be a lot of starting guides and advanced strategies on how to purchase a door lock, but the suggestions given may not have universal significance. It may be more meaningful to objectively give the respective scope of application of mechanical locks, electronic locks and intelligent locks.

Mechanical lock: Although not dead, the situation has gone

Even in the era of intelligence, mechanical locks are not useless. The biggest advantage of mechanical locks is that their solutions are mature enough, their products are mature enough, and they are almost suitable for most scenarios. There is almost no education cost for users.

In China, electronic locks have been developed for 10+years, and intelligent locks have been developed for 5+years. By 2017, mechanical locks still occupy at least 80% of the market share in the terminal market, indicating the degree of familiarity and dependence on them.

Some people say that mechanical locks are still the mainstream because of their competitive advantage in price. In fact, the mechanical lock will eventually lose its price advantage, or although the mechanical lock will maintain its price advantage, the price will no longer be the priority factor for users to purchase the door lock.

The fundamental reason for the elimination of mechanical locks is not that their security level is not high, but that all mechanical equipment and all electrical equipment in the whole building and its home, hotel, office, business and other spaces are tending to IOT, becoming IOT terminal equipment, and mechanical locks are no exception. At present, the mechanical lock has been exhausted by Jiang Langcai, and the situation has gone.

Of course, even in the era of the Internet of Everything (IOT), the marginalization of mechanical locks does not mean the complete disappearance of mechanical locks. It will still be an indestructible "lock strength" and will still be purchased and used by a small number of users in a small range and certain scenarios.

Safety. The decisive factor of the safety performance of mechanical lock is the lock cylinder, which is divided into Class A, Class B and Class C. If the C-level lock cylinder is equipped, the safety of the mechanical lock can also be basically guaranteed, and it also has a wide range of scenario applicability.

Durability. The mechanical lock does not need power supply, and there is no theory of endurance. As long as the lock cylinder and lock body are not damaged, they can be used all the time.

Price performance ratio: the mainstream price of mechanical locks is between 150-500 yuan. For users with low security requirements, mechanical locks can still be used.

Electronic lock: Although it is accessible, it may be a flash in the pan

The electronic lock is actually a combination of fingerprint lock, password lock and other locks. The most representative one is fingerprint lock - a lock that does not access the Internet and has no intelligent capability. In addition to fingerprint unlock, it integrates password unlock, card unlock (magnetic card, TC card, TM card), and retains the key unlock mode.

The difference between an electronic lock and a mechanical lock is that it adds an electronic module. The difference between an electronic lock and a smart lock is that it is not connected to the Internet and does not have intelligent capabilities. The scale and speed of the electronic lock's tendency to IOT depend on its ability to play with the smart lock. To be exact, the game between the two sides is subject to a landmark review of the security event of the smart lock, Once the user's security risk of the intelligent lock networking is equal to the security risk of the electronic lock non networking, the electronic lock will be fully networked and intelligent.

At present, although fingerprint lock can be used as an entry-level option, it may also be a flash in the pan in the evolutionary history of door locks.

Security, the security performance of electronic lock mainly depends on which fingerprint identification technology is used, and the security level of the lock core is reduced to a secondary position. The security of optical fingerprint sensor is relatively low, while the security of living fingerprint sensor has been substantially improved. No matter which fingerprint identification technology is used, the security is more than one order of magnitude higher than that of mechanical lock.

Convenience. Since fingerprint is recommended as the preferred unlocking method, and other unlocking methods such as password, card and key only exist to meet a small number of users, the basic convenience of fingerprint locks can be guaranteed at a speed of about one second.

Durability. Although the lock cylinder and lock body of the fingerprint lock are still mechanical, the electronic module needs power to provide standby life. Most fingerprint locks on the market have a life time of less than one year or about one year, and the battery replacement frequency is barely acceptable to users. What should be noted is the reliability of the fingerprint identification module, which requires more brands for horizontal comparison.

Price performance ratio: the mainstream price of fingerprint locks is between 2000 and 3500 yuan, and 60%+consumers choose fingerprint locks with a price of 1000 to 2500 yuan. At present, the market share of fingerprint lock is less than 20%. For users who have high requirements for security but mind the price of intelligent lock, fingerprint lock can be used as an entry-level option.

Smart lock: Fanghua is emerging, more intelligent in the future

Compared with fingerprint locks, smart locks are not just as simple as adding networking functions. A real smart lock should be a computer with advanced security functions, which are used for security defense of basic functions, convenient access to extended functions, scene management and scene services of advanced functions, far from being covered by a variety of unlocking, remote authorization, real-time viewing, etc.

If almost 100% of mechanical locks and fingerprint locks are produced by lock manufacturers, then intelligent locks are produced by IOT companies, ICT companies, door lock start-ups, Internet companies, home appliance companies, traditional lock manufacturers and other different factions. The whole machine scheme, performance configuration, industrial design, APP interaction and even product concept are quite different.

Although the share of the current smart lock is small, the first window of all smart life scenarios, such as smart homes and smart apartments, is emerging, and it is inevitable to reach the future.

For security, the intelligent lock is connected to the network, and the functional differences such as real-time viewing, real-time alarm and remote authorization are ignored. The core difference is whether the intelligent lock can be jointly deployed with other security devices such as curtains and balconies to build an indoor and outdoor 360 degree × The general difference of 24-hour safety protection network is reflected in the traditional sense of fingerprint identification and the level of lock cylinder. With the addition of real-time alarm and joint defense, the security of the smart lock has been improved in an all-round way compared with the fingerprint lock.

Convenience. Like fingerprint locks that are not connected to the Internet, fingerprints are also recommended as the preferred unlocking method. Passwords, keys and other unlocking methods are reserved only for standby. Smart locks are more convenient than fingerprint locks in that they can support password unlocking under remote authorization. At the same time, fingerprint unlocking speed of smart locks is a little smoother than fingerprint locks, mostly between 0.5 and 1 seconds.

For durability, the battery life of the smart lock is generally designed to be a little longer than that of the fingerprint lock. However, because the smart lock has the networking function, its durability is not limited to the battery life, but also depends on whether the embedded system of the smart lock supports OTA upgrading, and whether the smart lock APP publicly promises short cycle iteration. This is exactly the most important factor for users to consider when starting smart locks. Battery life only affects daily experience. Firmware and APP will determine how long the smart lock can be used or even whether it can be used.

Price performance ratio: the mainstream price of smart locks is between 2500-4000 yuan, and 80%+consumers choose smart locks at the price of 2500-3000 yuan. In 2017, the market share of smart locks was less than 5%. However, smart locks have become the black technology representative and high appearance person in the category of door locks. For users with high security and appearance requirements, smart locks are the best choice.
