password locks are widely used in some places with strict precautions. This situation generally requires us to have a very high level of security for door locks. Password locks are chosen to meet this demand. Next, let's see which brand of password locks is good.
which brand of combination lock is better
1. Adele
Adele used to be positioned as a "door lock expert", but now she has been transferred to a "fingerprint lock expert". Coupled with a strong publicity campaign, Adele has made great progress, but the rapid development has also brought hidden dangers to it. In order to build an industrial chain, the product line has been continuously extended, which will affect the development of brand value. At this stage, what Adel has to do is to shrink the product line and focus on building brand-superior products.
2. Deschman DESSMAN
Deschman is a German brand, with the most complete R&D and production center of fingerprint locks in China and many patents. Its Hausmann style is well-known in Europe and lasts forever. However, Deschman is also expanding its product line, and whether the after-sales service can keep up will also affect the value of its brand.
which brand of fingerprint lock is better
3. Nomex RAMAX
The first brand of fingerprint lock in Korea, it is a little unfair to put RAMAX brand in the third place here. All products of this brand are imported from Korea, and it is the only "EU CE Certification" brand known as "European and American Pass" in the industry. Testech algorithm, the world's top fingerprint technology, is adopted, and the quality of products is guaranteed to the greatest extent by relying on the cutting-edge electronic technology of South Korea. Although the current market share is small, the future cannot be * * *. Its concise international design will subvert the traditional concept of the industry.
principle of password lock
multi-dial
The simplest password lock is commonly used in bicycle locks with low security settings, and uses multiple dials. There is a recess in the middle of each circle. A shaft in the center of the lock has several protruding teeth on it to catch the shifting ring. When the dial is turned to the correct password combination, the lock can be opened. This kind of lock is the easiest to open. Many of these locks can be opened without knowing the password at all. Unless its internal components are made perfectly, as long as the axis is pulled outward, one of the teeth will tighten the dial ring more than the other. At this time, turn the tightened dial until a small "click" sound is heard, indicating that the tooth has entered the correct recess. Repeat this step and you will soon be able to open the lock.
Single turntable
A combination lock used on a padlock or a box can have only one turntable. The turntable pushes several balance discs or cams at the back. It is customary to turn the dial clockwise to the first digit, then counterclockwise to the second digit, and so on until the last digit. There is usually a recess on the cam. When the correct password is turned in, the lock can be opened when all the bits are in line. This combination lock is relatively safe, but it is not without its shortcomings. For example, some password padlocks can pull the lock head, and then turn the turntable until it can no longer move, so that the password can be found out. There is also a specific relationship between the digits of some rotary password locks, which greatly reduces the possibility of password combination. Cheap password padlocks can be opened with special linings without using passwords. The combination lock used in the box is relatively tight in structure. Experienced locksmiths can use the receiver to listen carefully to the sound of the cam in the lock and judge the possible password while rotating the turntable.
The main types of password locks
Mechanical password locks
Mechanical password locks are relatively stable and durable, and do not need power. However, the operation method is slow to learn, inconvenient to operate and requires professionals to modify the password.
electronic password lock
electronic password lock has the advantages of fast operation, simple and random password modification, and can be unlocked only by inputting -9 digits. Although the price of electronic password lock has dropped and the quality has improved in recent years, it is not as stable and durable as mechanical password because of its complexity.
swipe code lock
swipe code lock can use its own IC card to open the door of the safe, which is simple to operate, but it requires a higher IC card. If it comes into contact with a strong magnetic object, the IC card may weaken its magnetism and cannot open the code lock.
Fingerprint locks
Fingerprints are hard to find in this world, so fingerprint identification technology is applied to safes, which is highly confidential and easy to use. However, the opponent's dry humidity requirements are strict! The recognition of the position of the finger is also relatively dull! Even if it is the same finger, if it is placed in a different position before entering the fingerprint and before opening the door, it may fail to recognize it!
How to change the password of the password lock
The first method: Generally speaking, there are three ways to change the password of the electronic lock: 1. Initialization, which is to press a key for a few seconds from the inside and re-enter the password; 2, it is the lock of the master control, which is modified from the computer of the switchboard; 3.
