As a smart lock product, the fingerprint lock is more and more widely used in the application of modern locks. Fingerprint lock is a kind of lock product with high safety performance. What factors do consumers need to clearly understand the safety performance of smart fingerprint lock when purchasing fingerprint lock? In order to facilitate future maintenance and use. Commonly affecting the security performance factors of fingerprint locks are emergency key, mutual opening rate, fire protection standard, user level, temperature/humidity, data protection and so on.

The emergency key is mainly for the fingerprint lock. Is there any other reliable opening method in case of system failure, fingerprint comparison failure or no power?

Inter-opening rate: At present, the technical indicators of some products on the market are not very good, and the mutual opening rate is only 1%. However, when selling, they advertise their product indicators and appearances, but the products have not undergone any tests at all, and the relevant indicators are very low. It is recommended not to buy.

Fire protection standards: Whether flame retardant materials are used and meet national/international fire protection standards. If there is too much fire within the specified time, can it be opened reliably?

User level: There are many products on the market that do not have level management. As long as you take the product manual, you can operate all the functions of any lock, thus losing the security significance of the fingerprint lock.

Temperature/humidity: The ability of a fingerprint product to adapt to temperature/humidity determines the scope and field of use of the user in a large sense. At present, some products have extremely poor adaptability to temperature and humidity. If such products reach -10 to 20 ° C in the winter in the north and 100% in the southern rainy season, the fingerprints cannot be collected because the electronic materials do not work. The product is out of order, so users should pay close attention to these indicators when selecting products.

Data protection: A good fingerprint lock product should have the data protection function after power off. However, there are some products on the market. When the power is exhausted, replacing the power supply will lose all stored information, and the user cannot open the door, which brings inconvenience to the user.

In summary, although the security performance of the fingerprint lock is relatively high, in the purchase process, all the factors that affect the security performance of the fingerprint lock are not considered to be up to standard, and the security performance of the high-quality fingerprint lock is greatly reduced.
