In the market, in addition to fingerprint recognition, some have the function of adding a password, so this kind of fingerprint lock is also often called fingerprint password lock. The fingerprint, password and emergency key can be turned on separately. The password function depends on the security setting. The password length is between 4-12 digits. The numeric keys generally use 0-9 full digital input mode. Of course, fingerprint locks are not as expensive as possible. When buying fingerprint locks, you should generally pay attention to "security, stability, versatility and intelligence."
1. Security After installing the fingerprint lock, it should not affect the function of the security door. There are no obvious security risks in the lock.
2. Stability is the most important indicator of fingerprint lock. It usually takes more than one year of actual use to stabilize and stabilize. Consumers should choose the manufacturer that mainly produces fingerprint locks when purchasing. Such companies generally have good production experience. R&D experience is the beststabilizing factor.
3, versatility should be applicable to most domestic security doors (in accordance with the 2008 version of the national standard for security doors), the amount of modification is small. Good fingerprint lock installation time should be no more than 30 minutes. Otherwise, it is generally difficult for users to complete the installation and maintenance themselves. The versatility is well designed to reduce dealer inventory.
4, intelligence Adding, deleting and other operations should be very simple, users do not have to remember too many passwords and codes. The high-performance fingerprint lock is also equipped with a video display system, which is convenient for users to operate.
5, the manufacturer brand If you ask me to choose the brand's fingerprint lock, I can only say that the best customer service, this is the focus of the choice of fingerprint lock. Only when the manufacturer's production quality is guaranteed, can the user's peace of mind be used; only if the manufacturer has after-sales protection, it is possible that someone can solve the problem in time (the product is not bad, we must not think that what we bought is impossible) Bad); only the quality of the manufacturer and the after-sales guarantee can prevent the user from being able to open the door and be locked out.
6, function Select the function of the lock, on the one hand to meet their own needs, on the other hand is also the quality of the lock. A good company often has no more than 5 high, medium and low fingerprint locks for users to choose. Users generally choose to use their own products: there are metal doors and wooden doors for the entrance door, there are user interior doors, common to wooden doors, also used for villa doors and so on. The basic functions commonly used are:
1), can be used for multiple people to open the door (in a family or office often more than one or two people), product quality should be stable, good performance;
2), you can open the door by permission (it is impossible for the head of the household to have the same opening management authority as the babysitter and cleaning tool);
3), can freely increase or decrease the fingerprint of the door opening (the babysitter can easily remove her fingerprints when leaving the job);
4), it is best to have a query record function (you can view the door record at any time, sometimes can become a key piece of evidence, generally with a display);
