After all, the household fingerprint door lock is not a comprehensive scientific and technological product. What should we pay attention to in the process of purchase and selection?

1. Emphasis on appearance and function. Household fingerprint door locks belong to household durable goods and are used on numerous doors. Therefore, the top criterion for the appearance design of household fingerprint door lock is two words: simplicity. Many household fingerprint door locks are designed to be large, and the products have a sense of luxury. However, once the door is installed, it often appears very abrupt, especially attracting the attention of people who "hide evil intentions".

2. Anti theft function of mechanical lock cylinder. Now household fingerprint door locks can be divided into two types: one without lock cylinder and the other with lock cylinder. According to the national regulations, the household fingerprint door lock is required to have a lock cylinder. After all, the household fingerprint door lock is an electronic device, which will show a fault condition, and the household fingerprint door lock with a lock cylinder can open the door when the electronic part shows a fault.

3. Degree of intelligence. As mentioned at the beginning of this article, a single household fingerprint door lock can complete the switch lock. If it can be connected to an intelligent mobile device, it can complete more functions. Not only complete the need of unlocking, but also grasp the security situation of the door more comprehensively and intuitively.

4. After sales service skills. If it is a domestic fingerprint door lock, it can get a relatively fast after-sales response, but the general household fingerprint door lock devices need to be booked by professionals. Maybe some friends in third and fourth tier cities are not in the service of this door-to-door device. We should understand this earlier. The professional skills of after-sales customer service personnel and the speed of response to problems are all needs to be considered.
