Smart fingerprint lock is currently the most widely used type of smart lock product. Because of the uniqueness of the fingerprint, the security of the smart fingerprint lock is greatly improved, which makes consumers very approve of it. So what are the types of smart fingerprint locks?
First, divided by anti-theft performance
According to the division of anti-theft performance, the currently popular fingerprint locks are classified into ordinary fingerprint locks and anti-theft fingerprint locks.
Ordinary fingerprint lock
There is not much difference with the original electronic lock. The important thing is to use fingerprint authentication, but it is not applicable to existing domestic anti-theft doors. Such fingerprint locks do not have world hooks and can not use the security door world security system (all imported fingerprint locks are not In accordance with national industry standards, it can only be used for wooden doors.
Fingerprint anti-theft lock
Better safety, can be applied to standard security doors and wooden doors. This kind of lock can automatically or semi-automatically connect the security door with the world lock system, without affecting the performance of the original security door.
Anti-theft performance is different, the market price is also very different. Fingerprint locks with mechanical anti-theft features are significantly more expensive than ordinary fingerprint locks without anti-theft features. Therefore, when purchasing fingerprint locks, you must first select the appropriate lock based on your door. Fingerprint locks are generally selected based on the application requirements.
Second, divided by identification carrier
According to the classification of identification carriers, fingerprint locks can be classified into optical fingerprint locks and semiconductor (capacitive, pressure bar and thermal sensing) fingerprint locks.
Optical fingerprint lock
It is relatively stable and adaptable. It is mostly used in anti-theft locks. It occupies more space than semiconductors and can still be used after being scratched by metal hard objects.
Semiconductor fingerprint lock
The volume is relatively small, and the identification scale is wider than the optics, especially for dry fingerprint users. However, semiconductor fingerprint locks have high requirements for the use of the environment and are easy to scratch. Generally used for special occasions (such as banking) and products (such as mobile phones, notebook computers), semiconductor life is much shorter than the use of optics.
The above is the type of smart fingerprint locks summarized by Xiao Bian. I hope to be helpful to everyone.
