With the continuous development of the smart home industry, the speed and degree of adoption of smart homes has continued to accelerate and expand, and people's acceptance has also been continuously improved along with the development of information technology. When the market demand changes, many home appliance companies, IT companies, and security companies have transformed and joined the emerging market and launched a series of smart home products, further accelerating the speed of market adoption.
Smart locks are intelligent products that were born earlier under the smart home boom. They can enter the door without a key and brush their faces to enter the door. This kind of scene seen from science fiction films has now entered life. However, there is a phenomenon of pseudo-intelligence in the smart home industry. The same holds true for smart locks. How can consumers choose the smart locks that are truly suitable?   
1, both appearance and function
Good product design does not stop at appearance. Smart locks are household durable goods that are used on a wide variety of doors. So the first principle of smart lock design is two words: simple. In other words, we should try our best to be concise and wild on the premise of respecting practical applications. Regardless of wooden or iron doors, Chinese or Western styles, they must have the finishing touch. Many fancy lock designs on the market are often poor grades.
2, the degree of intelligence
In the age of the Internet of Things, one of the criteria for using mobile terminals to intelligently identify whether homes are truly "smart" is to use them. Fingerprint locks, password locks, and sensor locks on the market today have become less “smart†under this standard. Aside from the cumbersome experience such as sensor locks, simple and convenient operation has become the mainstream of the market. Using the APP to monitor and control the smart lock of the door lock is the main direction of the current market. For example, smart house smart locks can use the mobile terminal to remotely control the door lock or open and close the door regularly.
3, intelligence does not forget the nature of security, multiple encryption can not be broken
One of the purposes of intelligence is to make security safer, not the other way around. The essence of the door lock is security. In modern times, a door lock that can cope with a complicated and changeable security environment is enough to deserve a smart label. Instead of showing off the gimmicks, it is better to be smart than to be able to truly guarantee the safety of users on innovative technologies.
4, deal with complex environments, strong product adaptability
Smart lock products are complicated because of the installation environment, and the environmental impact is also quite large. Such as wireless signal docking, signal interference, signal shielding, etc., will directly affect the lock experience. Many so-called smart locks rely on the Wi-Fi environment, and they are useless if they lose the network. The smart house smart lock should keep the traditional mechanical key unlocked, and it can also carry out fingerprints, passwords, and swipe cards to open and close the door locks. You don't have to worry about the phone's poor signal and no Wi-Fi, so this is also important for users.   
5. Strict inspection by authoritative organizations, and one complete report certificate
For a new era of electronic products, the reliability and safety of quality are very important. From the repeated detection of the whole to the details, the excellent smart lock will not miss a link that may go wrong. After passing the inspection by the national authorities, it is very important for the service of the product. Consumers should be aware of whether the test report is consistent with the actual product when purchasing. Many smart lock companies claim to have passed the inspection, but in fact only the mechanical lock products are inspected.
6, the price is not water, the quality is not false
China's building materials industry is still in a state of high sales price, and has always refused to infiltrate the Internet's thinking mode. It is a scam that the price of ordinary fingerprint locks with low cost is 67,000 or tens of thousands of dollars, and the smart locks with a price of about 2-3 thousand are already of higher quality. High cost performance is the pursuit of an excellent product. With the popularity of Internet technology, the price of smart locks may continue to decline.
7. Perfect and sound service system
A good after-sales service allows you to avoid the installation, maintenance troubles, the current lock market has not formed a perfect after-sales service market, therefore, the perfect after-sales service network is very important, always for the sake of customers after-sales service must be timely and effective solution to all possible The problem of emergence is the basic quality that all outstanding modern enterprises should have. As a smart home brand enterprise, smart house companies will solve the problem of product installation and quality in terms of installation and after-sales service. We will solve the problem for users at the first time, because your trust is the cornerstone for us to step into the distance.
