In addition to fingerprint unlocking, the fingerprint lock is also equipped with password unlocking. The password of the electronic lock is easy to be stolen because the number of digits is small and the number is fixed. In order to avoid this risk, the fingerprint lock uses the virtual password technology! The user can add arbitrary garbled codes before and after the correct unlocking password. These entered numbers will be grouped, analyzed and compared one by one, and the door will not be opened until the same password as the memory chip is found. This technique lengthens the number of digits and reduces the risk of being deciphered. Although there are certain restrictions on the number of digits of the virtual password, generally ranging from 20-50 digits, it has a higher security factor than the electronic lock password with less than ten digits.
Anti-pry alarm function
The fingerprint lock system is composed of two parts: an intelligent monitor and an electronic lock. Since the two share the same circuit, data can be transmitted to each other. When the lock is attacked by external forces, some parts will shift, causing the alarm switch to be pressed and activated. After the monitor receives the alarm signal, it will transmit the alarm signal to the user’s mobile phone through the built-in WiFi. The realization of this alarm function is not a passive alarm like an infrared detector, but an active alarm before the thief enters the door, which is safer and more reliable.
