Why smart electronic door locks must keep the key hole

Many people who do not understand the fingerprint lock will have one of the fingerprint locks. "Clearly it is a smart lock. Why do you have to use a key to open the door?" "What is the difference between a key hole and an ordinary lock?" "This is not equal to taking the initiative. Thieves opportunity?
Fingerprint lock mechanical lock cylinder is not an exception, the most important is for security considerations. Of course, many friends who do not pay attention to fingerprint locks are certainly not aware of them. Then Xiaobian will give you specific explanations.
In fact, many of our customers have also asked us, can we not open the door to the key function? The answer is negative because the country has stipulated that smart locks without emergency keys cannot be shipped from the factory. In the event of a fire, a smart lock without a mechanical lock cylinder will fail or the main control board will melt, and the escape door cannot be opened. A terrible accident will occur in the building; on the contrary, if a mechanical lock cylinder is equipped, the mechanical key can be used to open the door, which greatly improves the chance of safe escape in critical situations.
Is it easy to be opened by a thief if you have a key opening function? Ordinary mechanical lock thief can be opened in only 5 seconds, because this is the most common and simplest A-level lock, which can be easily opened without excessive technology. So this type of lock became the first choice for thieves. The shorter the time it takes to open the door lock, the lower the risk of committing the crime; on the contrary, the longer the time, the greater the risk.
Smart fingerprint locks These types of locks are locks that cannot be opened technically after 270 minutes of technical verification by the public security department. The mechanical key of the smart lock adopts the technology of inner milling and outer milling serpentine trough double-sided side column. The dentifrice is extremely complicated and cumbersome. It is impossible to use tin foil to fit the key to open the door, and it is impossible to privately match the key. At the same time, the anti-collision steel bar of the smart lock adopts a super strong solid 304 stainless steel fixed rod, which effectively prevents the tools such as interruption, twisting, and impact to open the door lock and any attempt to break the lock and forcibly enter the house.
The fingerprint lock's keyhole position is mostly hidden and will not be easily found. Moreover, because the daily use of fingerprint identification, passwords, etc., is generally not required to use the key, it eliminates the need for a new lock when the key is lost, and is not afraid of other people holding their own keys (such as decoration workers, former men/girlfriends). some type of). At the same time, fingerprint lock has an independent information management function, you can freely increase, delete and modify the user's fingerprint records. The password can also be modified at any time, which is more convenient.
In addition, the use of mechanical locks will occur when the door lock is not closed, and the fingerprint lock has a false alarm function, the door is not closed fingerprint lock will issue an alarm to avoid the loss caused by carelessness.
Then for anti-violence and anti-violence unlocking, this issue is related to the quality of the lock cylinder. Whether or not there is a keyhole, the quality of the lock cylinder is too low, and it can still be opened by violence. What's more, the fingerprint lock is equipped with a flood prevention alarm. When the door is opened with violence, it is Fingerprint locks also emit long warning sounds.
Therefore, the fingerprint lock that retains the keyhole is not equal to the mechanical lock, but is better refined on the basis of the mechanical lock. The use of scientific and technological means to make a series of security plans with targeted insecurity factors can better ensure the safety of our daily lives. In the final analysis, the lock is basically a lock cylinder level, and the most important core of a fingerprint lock is the lock core level and technical capabilities. Therefore, when buying, it is necessary to see the essence and not to be confused by the appearance!

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Specification

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
