Which brand of fingerprint lock for household use is better? The fingerprint lock installer tells you

A lock installation master who has been engaged in nearly 10 years chatted with me and said that many consumers do not know enough about fingerprint locks and want to install fingerprint locks, but they don't know which brand of fingerprint locks is better. He said, in fact, the quality of the fingerprint lock is good or bad, just look at 3 points. Let’s summarize some of the knowledge points taught by the master. Those who don’t know about fingerprint locks and want to install fingerprint locks, don’t miss it. Which brand of fingerprint lock is good-look at the lock body of the fingerprint lock First of all, the most direct factor that affects the quality of the fingerprint lock is the material used. The appearance of the fingerprint lock may look the same, but the material is different. The commonly used materials for the body shell of fingerprint locks are plastic, plastic + alloy, steel, stainless steel, aluminum alloy, zinc alloy, and copper. Due to the extremely high cost of the pure copper lock body shell and the extremely complicated process, it is generally rare in the market. General households can choose other materials with higher cost performance. If you want a fingerprint lock that is corrosion-resistant and anti-violent, it is recommended to buy a fingerprint lock with a stainless steel body. Usually a good lock body is made of 304 stainless steel, and the bolts are all solid. If it is difficult for us ordinary consumers to distinguish the quality of the lock body, then it can be distinguished from the weight. If a fingerprint lock is held lightly in the hand, the quality is not so good. Nowadays, some brand locks on the market still use plastic shells. The whole locks are very light, not only non-wearing and corrosion-resistant, but also extremely easy to be destroyed by violence. Which brand of fingerprint lock is good? Look at the lock core of the fingerprint lock to determine the anti-theft factor of the lock. In the national standard, locks are divided into two types: Class A locks and Class B locks. In fact, there are Class A locks, Class B locks, and Super Class B locks (also called Class C). The higher the level, the higher the safety performance. Although the B-level and the super-B level belong to the national B level, the difference in safety performance is very big. From a technical analysis, A-level, technically open for more than 1 minute as the qualification standard; B-level lock, prevent technical opening time of not less than 5 minutes; Ultra-B-level lock, the lock core is monitored by the relevant department and cannot be opened technically, or Prevent technical opening time not less than 270 minutes. For family safety, we should naturally choose a fingerprint lock with a super-B key cylinder. Which brand of fingerprint lock is good? Since the fingerprint sensor type of the fingerprint lock is a fingerprint lock, the 'fingerprint' is naturally an important part of our whole set of locks. The type of fingerprint sensor determines the convenience and safety of use. At present, the sensors on the market mainly include optical sensors and semiconductor sensors. Optical recognition is an earlier fingerprint recognition technology. For example, many time attendance machines and access control systems used this technology. The disadvantage is that it is greatly affected by whether the surface of the finger is clean. If you stick a lot of dust on your fingers, or wet fingers, there may be recognition errors. There is also easy to be deceived by fake fingerprints. Optical is to take a photo of your fingerprint. Every time you identify it, you compare the photo of your fingerprint. If someone steals your fingerprint, you can open it. For users, it is not very safe and stable to use. Therefore, a good, cost-effective fingerprint lock can be considered from the following three points: whether it is a stainless steel lock body; whether it is a super B-level lock cylinder; whether it is a semiconductor fingerprint head. At this point, the master mentioned that the famous fingerprint lock is good. It uses precision cast 304 stainless steel lock body, European standard. The lock body has been tested at constant temperature and humidity, and has good anti-corrosion and anti-rust effects. It has 5 patents. The whole lock weighs 10 kilograms, which is very heavy. The lock core is super B-class, and the lock body has a built-in clutch, and the lock core and the lock body are connected. The door lock cannot be opened even if it encounters violent damage, which has a good anti-collision and anti-prying effect. In addition, the Swedish FPC semiconductor fingerprint sensor is also used, which has a very high recognition rate, even the fuzzy fingerprints of the elderly and the shallow fingerprints of children can be recognized. Finally, I remind everyone that different configurations have different prices. Everyone depends on personal needs and chooses rationally. In addition to price, quality, brand, and after-sales service are also critical.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , lock manufacturing, custom door lock, and custom door lock are widely used.
