The development of science and technology is getting faster and faster, and society has begun to become smart. Even intelligent robots that previously only appeared in movies have begun to use people's homes. Smart homes are also becoming more and more popular, and smart fingerprint locks have gradually begun to enter people's lives.
Fingerprint locks, as high-tech products, rely mainly on electronic technologies and biometrics. The simpler the role of these technologies is, the better. Conversely, the more auxiliary functions, the more likely it is to reduce the stability of the main functions. Therefore, there are several functions when selecting the fingerprint door lock.
1, fingerprints open fingerprint lock As the name suggests, the most basic is the fingerprint open function. Fingerprinting on the market currently uses optical fingerprinting methods, and a few use semiconductors. Semiconductor acquisition technology is susceptible to static electricity, sweat, dirt, finger wear, etc., has insufficient stability, and is not as resistant to wear. Optical acquisition can achieve multi-angle all-round collection, can achieve the best accuracy, fingerprints clear, stable identification, and effectively improve the stability of semiconductor acquisition, therefore, in the field of smart fingerprint lock applications.
2. Information Management Functions The information management functions mainly include: Users can be added, modified, or deleted at will. User information mainly includes fingerprint information and usage information. When a customer uses one of these features, other features are not affected. If you can use the fingerprint + password together, or use the password + credit card together, etc., double password more protection.
This function can effectively improve the convenience of fingerprint door locks. For example, when relatives at home need to stay for a few days, only the fingerprints of relatives can be entered, and relatives can open the door freely without assigning keys to relatives. After the relatives have gone, they can't open the door as long as the information is deleted. At home, the nanny and the moon were asked to remove their fingerprints after resigning. There is no need to worry about the nanny stealing keys.
3, the key to open Many consumers will think that there are many keys to open the function, the use of fingerprint door lock is to facilitate. If you also add a key to open the function, and what is the difference between ordinary locks, safety can be guaranteed? In fact, this is a requirement that the country sets for security considerations - smart fingerprint locks must have a key opening function to leave the factory.
Fingerprint locks are electronic products after all. Electronic products may have business trips or no electricity. To prevent fires or other disasters from damaging electronic circuits and causing people to endanger the situation, the national mandatory fingerprint door lock must be equipped with a key opening function. . Without the key opening function, it is not qualified.
4. Virtual bit password function The virtual bit password function is to use the password to open the door. You can freely enter any number before or after the correct password to open the door, which can effectively prevent the password from being peeked.
5. When the flood warning function is damaged by external violence, it will automatically sound an alarm to remind neighbors. I think no thief would continue to shackle the sound of the alarm.
