The function of choosing a lock is not only to meet one's own needs, but also to ensure the quality of the lock selection. A good enterprise often has no less than 5 fingerprint locks ranging from high to low for users to choose from. Users usually choose to use their own products from them: there are those used for entrance doors, which are divided into metal doors and wooden doors, those used for user interior doors, commonly including wooden doors, and those used for villa entrance doors, etc. The basic functions commonly used are:
(1) Can provide fingerprint access for multiple people (often more than one or two people in a home or office), with stable product quality and good performance;
(2) It is possible to open the door with different permissions (it is impossible for the homeowner, nanny, and cleaner to have the same door management permissions);
(3) You can freely add or remove fingerprints when opening the door (the nanny's fingerprints can be easily removed after leaving);
(4) It is best to have a query record function (you can view the door opening records at any time, which can sometimes become key evidence and generally require a display screen);
(5) Add some password function appropriately (since the fingerprint part is an electronic part that may be damaged, the homeowner can use the password to open the door in a temporary situation). When choosing, try not to choose products that highlight the password function too much, as passwords are not as secure as fingerprints. There are usually two types of keys: 4 keys and 12 keys. Try not to use passwords to open doors in daily life as it can effectively prevent theft;
(6) It is necessary to have a mechanical key, which is a backup way to open the door. Although airplanes and cars have automatic control, they still retain the manual control part, which is a safety consideration; Any electronic part has the possibility of error, while the mechanical part is relatively more stable. Keeping the mechanical key of the lock as a backup door opening method at home can open the door in a timely manner and facilitate maintenance when there is a problem with the electronic part of the door lock. Imagine if there is a fire at home, or if a thief damages the electronic part of your door due to not prying open the lock, what would you do? Don't be tempted by the so-called safety in your mind and ignore your options, choosing locks without mechanical keys. In fact, the most important thing when using a fingerprint lock is not to improve security, but to enjoy the convenience of the fingerprint lock. If it is necessary to enhance the security of the fingerprint lock, it can be connected to the smart home system. Some fingerprint lock manufacturers reserve development ports for fingerprint locks. In smart homes, simple development of fingerprint locks is sufficient to monitor their status in real time, thereby improving the security of fingerprint locks;
(7) Choose a good lock cylinder. The quality of the mechanical key lock cylinder directly affects the anti pry and stability of your door. This part is also very important. No matter how good the fingerprint lock is, it ultimately cannot be separated from the lock core. In general, manufacturers of fingerprint locks with strong capabilities will choose high-end lock cores, so that product quality can be guaranteed. The most obvious feature, especially for consumers, is that they can check the number of pins and depth levels of the key. Try to choose products with a higher number of marbles and depth levels. The number of pinballs in the depth range is the key quantity of this mechanical key, and the larger the key quantity, the better the security. National standards generally require at least A-level locks, and good fingerprint lock manufacturers generally equip them with mechanical keys that exceed B-level;
(8) It's best not to use other fancy features. Basically, they are not practical. Adding one more function increases the possibility of damage. After the product breaks down, you will not repair it. If it is repaired, the repairman will charge you for the repair fee (not free of charge).
