　　Among them, price differentiation is an obvious feature in the popularization of smart door locks. At present, the price of smart door locks on the market ranges from a few hundred to several thousand. Faced with the big price difference, it becomes difficult for consumers to choose smart door locks. Those who are too cheap are worried about "moisture" in safety performance, while those who are too expensive are afraid of being "cut with leeks". Smart door locks, how should we choose?

　　Security lock selection criterion

　　Generally speaking, we can consider the safety performance, ease of use and applicable ecology of smart door locks.

　　First of all, the security performance of the smart door lock must pass. Specifically, we can pay attention to the lock body, lock core and identification of unlocking methods. In the choice of lock body, the security of electronic lock body is generally better than that of mechanical lock body, because electronic lock body can prevent criminals from picking locks and breaking them down. As for the type of lock cylinder, the C-class lock cylinder is the lock cylinder with the highest security level in the industry at present, so we need to pay attention to the information of the lock cylinder when choosing the smart door lock.

　　Identifying the way to unlock the door is a double-edged sword for the smart door lock. With the addition of fingerprint or face recognition, the embarrassment of forgetting to bring the key into the house will no longer be staged. However, if the identification lacks sufficient security, the possibility of the door lock being cracked will also be greatly increased.

　　For example, some smart door locks that still use optical fingerprint recognition are easy to be cracked by silicone analog fingerprints, while some smart door locks with face recognition function may be able to easily open the door locks with a photo because of the lack of sophisticated 3D face acquisition technology.

　　Usability lock selection criterion

　　Secondly, the use of smart door locks should be convenient enough, which not only requires smart door locks to have more ways to identify and unlock, but also ensures the success rate of identifying and unlocking.

　　Therefore, we can pay attention to the fingerprint recognition of the elderly or children by the smart door lock with fingerprint recognition function, while we need to pay attention to whether the smart door lock with face recognition function has the ability to resist the interference of ambient light.

　　Moreover, the ease of use of the smart door lock is also related to the action level of the user opening and closing the door. At present, the smart door locks on the market can be roughly divided into two types: full-automatic smart door locks and semi-automatic smart door locks.

　　Semi-automatic smart door locks are mostly hand-held smart locks that are improved on the traditional mechanical locks. Generally, it takes two or three steps to unlock. For example, after fingerprint or other identification, users need to manually press the door handle to unlock, and the lock after closing also needs to be lifted.

　　The fully automatic intelligent door lock is driven by a motor in the whole process. After the user uses fingerprints, magnetic cards, passwords, etc. to open the door, the lock tongue can automatically retract and unlock. The user only needs to push and pull lightly to enter the door, without unnecessary operations such as rotating the door handle. When closing the door, the lock tongue will automatically pop up and lock, which is very convenient. ?

　　Compared with the automatic intelligent door lock, the semi-automatic intelligent door lock is undoubtedly superior in convenience. When you enter the door with heavy objects in your hands, the fully automatic intelligent door lock can push the door straight after the fingerprint is unlocked, and the user does not need to free his hand to rotate the door handle to open the door, which is more convenient and humanized.

　　Intelligent lock selection criterion

　　Finally, we can pay attention to the ecology of smart door locks, which is mainly aimed at users who are interested in building whole-house intelligence.

　　If most of the home appliances we buy come from the same brand, we can link the smart door lock with the home appliances through smart gateway, WiFi and mobile APP to realize more scene applications.

　　For example, when the door lock is unlocked successfully, household appliances such as lights, curtains and air conditioners will be turned on simultaneously; When we leave home, the door lock can link the camera with one button to protect, intelligently monitor the situation at home, and make our home life safer.
