The function of choosing a lock, on the one hand, is to meet your own needs, and on the other hand, it is also to choose the quality of the lock. A good company often has no less than 5 fingerprint locks ranging from high to medium to low for users to choose. Users generally choose to use their own products: there are for entrance doors, divided into metal doors and wooden doors, there are user inner doors, common wooden doors, also used for villa doors and so on. The basic functions that are commonly used are:
(1) It can be used for multiple people to open the door with fingerprints (there are often more than one or two people in a home or office), and the product quality should be stable and the performance should be good;
(2) The door can be opened with different permissions (it is impossible to let the head of the household have the same door opening management authority as the nanny and cleaning tools);
(3) You can freely increase or decrease the fingerprints of the door opening (the nanny can easily remove her fingerprints when she leaves);
(4) It is best to have a query record function (you can check the door record at any time, sometimes it can become a key evidence, and it is generally necessary to have a display screen);
(5) Appropriate with a bit of password function (after all, the fingerprint part is an electronic part may be broken, and the householder can use the password to open the door in a temporary situation), try not to choose a product that highlights the password function too much, after all, the password is not as safe as the fingerprint. There are usually two types: 4 keys and 12 buttons. In daily life, try not to use the password to open the door, which can effectively avoid being stolen;
(6) Be sure to have a mechanical key, which is a spare way to open the door, like an airplane and a car, although there is an automatic control state, but the manual control part is still retained, which is a safety consideration; Any electronic part has the possibility of error, relatively speaking, the mechanical part is much more stable, and the mechanical key of the lock is retained as a backup way to open the door at home, which can open the door in time and facilitate maintenance when the electronic part of the door lock has problems. Imagine what you would do if there was a fire in your home, or if a thief damaged the electronic part of your door because he didn't pick the lock? Don't covet the so-called psychological security, and ignore the back road, and choose the kind of door lock without a mechanical key. In fact, the most important thing to use a fingerprint lock is not to improve security, but to enjoy the convenience of the fingerprint lock, if you need to strengthen the security of the fingerprint lock, you can connect the fingerprint lock to the smart home system. Some fingerprint lock manufacturers reserve development ports for fingerprint locks, and in smart homes, only need to carry out simple development of fingerprint locks, and the status of fingerprint locks can be monitored in real time, so as to improve the security of fingerprint locks;
(7) Choose a good lock cylinder. The quality of the mechanical key cylinder is directly related to the burglar-resistant and stable of your door. This part is also very important, no matter how good the fingerprint lock is, it is ultimately inseparable from the lock cylinder part. Under normal circumstances, powerful fingerprint lock manufacturers will choose high-end lock cylinders, so that the product quality will be guaranteed. The most obvious is that consumers can take a look at the number of pins and shades of the key. Try to choose products with more marbles and shades. The number of marbles in the shallow gear is the amount of the key of this mechanical key, and the larger the number of keys, the better the security. The national standard generally requires at least Class A locks or above, and good fingerprint lock manufacturers generally configure super Class B mechanical keys;
(8) Other fancy functions are better not to. Basically, it is not practical, one more function and one more bad possibility, after the product is broken, you repair it or not, if you repair it, the maintenance personnel will charge you for the maintenance fee (the door-to-door is not free).
