Lock, as the first protective barrier in our family, has no doubt about its position in the family. With the emergence of smart locks, many people still hold a wait-and-see attitude because of the low penetration rate, and the understanding of smart locks only comes from the news on the Internet. So, what details should we pay attention to when we want to buy smart locks? Please see the introduction below.
Which is better for fingerprint identification?
At present, fingerprint identification technology is quite mature. In fingerprint lock, optical fingerprint identification and semiconductor fingerprint identification are commonly used. However, from the security point of view, semiconductor identification is living body identification, which can play a very good role in preventing fingerprint duplication and unlocking. It is also the mainstream identification method in the market at present. The advantage of optical fingerprint identification is that the principle is simple and the cost is low. If the fingerprint is stolen, it can’t be stopped. At the same time, the sensitivity of optical recognition is easily affected by the environment, such as temperature. If you buy a smart fingerprint lock, it is better to choose a semiconductor to identify it.
Electromagnetic resistance should be guaranteed.
In terms of electronic protection performance, it is necessary to set up electromagnetic defense. The "black box" in the market is to break electronic components by instantly emitting a high magnetic field, causing the system to crash and restart, thus achieving the purpose of unlocking. Generally speaking, the products that can be opened by the "black box" are all inferior products, and there is no protection to reduce costs. When purchasing, you need to choose a regular smart lock manufacturer brand.
Choose a brand with package installation and after-sales service
Some people say that their manual ability can be installed by themselves, but the installation of smart fingerprint lock needs a master with relevant experience. Smart fingerprint lock involves mechanical parts and electronic parts. If the electronic parts are accidentally damaged, it will not be worth the loss. Correct installation can also reduce the occurrence of faults, and stable after-sales is the guarantee of smart fingerprint lock. When purchasing, it is recommended to have a brand of after-sales service and package installation service.
The above is the introduction of the details of purchasing smart fingerprint locks, which is summarized for everyone. If you want to know more about smart locks, please pay attention to China Smart Lock Network.
