The biggest feature of smart fingerprint locks is security and convenience. The security of fingerprint locks is mainly reflected in the use of higher security capabilities of the lock body and a security warning function, in which the security performance of the lock body is a basic core of fingerprint lock security. So how do you judge the merits of a smart fingerprint lock?

How to distinguish the advantages and disadvantages of smart fingerprint lock

First, look at the material

The lock body includes three parts: the main body, the lock tongue and the lock core. The material of the main body of the fingerprint lock lock body is mainly composed of zinc alloy and stainless steel. The wear resistance and impact resistance of the zinc alloy are far inferior to those of the stainless steel, and therefore the deformation is easy. Should choose stainless steel lock body, and preferably 304 stainless steel; bolt is one of the main parts of the bearing, must be solid and reliable, the same 304 stainless steel is better; the lock core is the core of the lock body, requiring wear, Collision-resistant and rust-proof, so the lock cylinder is generally made of pure copper.

Second, look at the lock cylinder

The lock cylinder is the key to security performance. The above said that the lock cylinder is preferably made of pure copper material, and the type and level of the lock cylinder are more important. The security level of the lock cylinder is generally three kinds, A, B and Super B.

The key of the A-level lock cylinder is flat. There are only single-sided single-row bullet slots. Some cross keys also belong to the A-class. Such a lock can be opened in about two or three minutes. It is even unsecure and even seconds open. The most unsafe is the fingerprint lock. Basically no manufacturers will use this type of lock cylinder.

Class B is a safer class. From the point of view of the key, it is a double-sided double-row bullet slot. If there is a tool for such a lock, the skilled worker must open it within 10 minutes.

Super B-level lock is currently the most secure grade. From the key point of view, the double-sided double-row bullet slots are usually next to it. There is also a blade or curve next to it. This kind of lock cylinder design technical standards should be opened more than 270 minutes.

Third, see the tongue

As mentioned above, the bolt is the main bearing component. Stainless steel is better. It must also be solid. The bolt's structure must be checked. General electronic locks have four tongues and five tongues, as well as double lock bolts. No matter what the structure is, it is better to lock more points, that is, when someone breaks through a bolt, there are other bolts that do not retract along with the linkage, so that they can continue to play a role.

Fourth, see the lock function

The function of the fingerprint lock lock body is not necessarily as good as possible, and the more functions, the more stability may be affected. However, one function is necessary, that is, the fire prevention function. The fire protection function is mainly embodied in the design of the lock body structure and the selection of materials. It is designed to ensure the integrity of the lock body in the event of a fire and the function can be used normally, providing protection for escape and rescue. Other functions such as anti-saw, anti-riot, and self-locking of the lock body are naturally better under the premise of ensuring the stability of the lock body.

The above is a summary of some methods of identifying the advantages and disadvantages of a smart fingerprint lock, and hopes to be helpful to everyone.
