1、 Professionalism

First of all, we need to judge whether the brand is professional enough, whether it is famous or not, whether it is a well-known professional security category, or a well-known category of other household appliance brands? On this issue, uncle's proposition is to choose products with famous brands in the field of security. In other words, this brand is to do security equipment and locks. It is professional because of its concentration.

2、 Security

Lock means locking and closing. It is a necessary object used to block public space and private space. As early as 3000 years ago, the ancients in China used locks. It is an important manifestation of private ownership. Its intention is to maintain the safety of their own space and goods. Therefore, when choosing finger lock, we need to consider security.

3、 Stability

Stability is the most important goal of fingerprint lock. Generally speaking, the stability of fingerprint lock is much stronger than that of mechanical lock. But the condition is that it is necessary to choose a good brand manufacturer. As uncle said in the first point, it is best to choose an enterprise whose main business is to produce locks and security equipment. Because such enterprises have satisfactory and rich production experience and excellent research and development foundation, they can effectively ensure the stability of finger lock in the application process.

4、 Generality

Unless you buy a door with fingerprint lock, you need to refit your existing door. Therefore, the universality of fingerprint lock is also an important goal of selection. Whether it is convenient in the process of device, whether it needs wiring, etc. should be taken into account. If the device is refitted or too messy, it is not recommended to buy it.

5、 Rapidity

In fact, intelligence means quickness. Therefore, when choosing a fingerprint lock, we need to consider how many intelligent functions it has, how many pieces of capacity the fingerprint can reach, how many groups of capacity the secret code can reach, whether there is voice prompt, whether it can be controlled wirelessly, whether it can connect with other smart devices at home or all smart homes, etc, We need to choose according to our own needs.
