The additional functions of Fingerprint Scanner are the functions added to the Fingerprint Scanner in addition to the basic door switch: such as doorbell, cat eye function, surveillance recording function, screen function, stay reminder function, intercom function, etc.
This function depends on the needs. Considering the stability and power consumption, it is recommended to buy a lock with a screen cat eye as the most basic one, which is the most practical.
The Fingerprint Scanner is related to whether you can go home every day, property and personal safety, so it is recommended not to buy small brands. They sell you locks for one or two years and go bankrupt at any time.
I am not afraid of 10,000, but I am afraid that if there is any problem, I don’t know who to find for compensation and repair. As long as it is a big brand and the after-sales service is guaranteed, blind selection is not a big problem!
Big brands have many after-sales outlets. If you can’t get into the house, you can make a phone call and someone will come to repair it immediately. It is still relatively reliable.
As for the big brands of Capacitive Fingerprint Scanner, you can basically go to e-commerce websites to choose a few top-ranked ones to buy, and you won’t go wrong.
In short, safety is our problem. After all, a wonderful smart life experience can only be enjoyed on the basis of personal and property protection.
