At present, electronic anti-theft locks (smart locks) on the market generally have emergency key holes, but they are convenient to use and do not prevent technical opening, which is no different from traditional hardware locks. There are no security upgrades!
At present, the smart locks on the market are divided into class A and class B according to the security level. At present, the security short board of the smart lock on the market is the lock cylinder and key. The safety of the lock cylinder determines the safety of the lock.
The technical unlocking standard is 5 minutes for class A and 10 minutes for class B. the mechanical strength of the lock body is divided into 15 minutes for class A and 30 minutes for class B according to the mechanical anti-theft lock standard.
At present, there are two kinds of intelligent locks in the market: anti-theft lock body and channel lock body. It involves the lock cylinder prevention technology opening and lock body strength. The safety level is determined by two factors: technical opening and violent opening.
At present, the specified opening time of the intelligent lock on the lock cylinder and lock body in the market is 5 and 10 minutes for the lock cylinder and 15 and 30 minutes for the lock body. The technical opening is relatively easy. The violent opening should be based on the prying off of the external protective surface and the mechanical performance of the lock body.
At present, there are only two types of intelligent locks on the market:
Technology opening and violence opening
Technology opening: it includes lock cylinder technology opening and information technology opening. The lock cylinder technology opening is of high probability, while the information security hidden dangers of intelligent lock, such as hacker, replication, interference, etc., are of minimal probability and easy to prevent.
Smart lock structure safety maximum hard injury:
1. There are keyholes and keys, ---- can not prevent the technology from opening!
Safety classification of intelligent lock structure:
Class A: (AO / A +) in 2 grades
structure characteristics
Ao: class a lock cylinder, keyhole, key and channel lock body
A +: Class B lock cylinder, keyhole, key and channel lock body
Safety features:
Unable to prevent technology from opening and violence from opening
For example, the smart locks on the market account for about 85% of the market, which is really worrying!
Level B: (Bo / B +), divided into 2 grades
Structural features:
Bo: class a lock cylinder, keyhole, key and anti-theft lock body
B +: Class B lock cylinder, keyhole, key and anti-theft lock body
Safety features:
Unable to prevent the opening of technology, increasing the difficulty of violent opening
Such as: household ordinary mechanical anti-theft lock, intelligent lock with electronic clutch lock body, and full-automatic intelligent lock in the market
Class C: (CO / C +) in 2 grades
Structural features:
Co: keyless, no emergency opening mode, class a channel lock
C +: keyless, no emergency opening mode, class B channel lock
Safety features:
Prevent technical opening, cannot prevent violent opening, no emergency opening (mechanical emergency opening mode must be reserved according to the national standard)
For example: Keyless smart lock, no emergency opening (mechanical emergency opening mode must be reserved according to the national standard).
Level D: (do / D +) in 2 grades
Structural features:
Do: keyless, emergency opening mode, class a anti-theft lock body
D +: keyless, emergency opening mode, class B anti-theft lock body
Safety features:
It is safe and convenient to prevent the opening of technology and violence
For example, Anja keyless smart lock uses a stepless password disc instead of the lock cylinder and key to push the push rod of the password disc to drive the clutch for mechanical opening.
Class a smart lock: with lock cylinder, lock hole, key and short board
Class B intelligent lock: with lock cylinder, lock hole and key, and the lock body is a short board
Class C smart lock: it is a low security smart lock that does not meet the security standards
Level D intelligent lock: it is a high security intelligent lock (Anja infinite password disk intelligent lock)
picture
ANGA's "no hole to enter" smart lock uses a limitless password disc to replace the lock cylinder and key, push the push rod of the password disc to drive the clutch, and press the handle to unlock.
At present, the existing intelligent locks in China include mechanical password lock and electromechanical intelligent lock. The number of passwords of mechanical password lock is not enough and it is easy to crack. Electromechanical intelligent lock has many passwords and is not easy to crack, which has been widely used in recent years. Electromechanical integrated code lock is a high-precision "C" level lock cylinder added on the basis of electronic lock code lock, so that it can be used urgently in case of electronic component failure, and the security and confidentiality are greatly increased, but it still needs to carry tangible mechanical key, and the mechanical key is easy to be copied. With the continuous improvement of people's living standards and the gradual strengthening of safety awareness, the safety performance and intelligence of locks directly affect people's home safety and convenience. At present, there are many problems in the safety and convenience of locks, which are not convenient and safe in the actual use process.
In order to overcome the problems existing in the existing locks in the world, our infinite password disk intelligent lock of Anja adopts a precision mechanical password disk to replace the mechanical lock cylinder and key of the existing intelligent lock, so as to solve the problems that carrying tangible mechanical keys can not effectively prevent technical opening, inconvenience, forgetting mechanical keys and easy replication of mechanical keys!
