Type of smart door lock
The intelligent door lock is divided into IC card door lock (plug-in type), magnetic card door lock (plug-in type), induction card door lock and TM card door lock. Currently, the most used ones are induction card door locks and IC card door locks. Management needs analysis, system cost selection is suitable for installing that type of door lock.

Because smart locks have different mechanical door locks, smart locks involve mechanical, electronic, and computer systems. It is recommended to use mature brands with good reputation. At present, there are many domestic smart lock brands, but the total production capacity is estimated to be less than 10%. Whether the development, production and after-sales of the manufacturer are standard enterprises, and whether there is a quality management system. There are a lot of users who have insufficient purchasing experience or only ask for cheap ones (those brands may have cheap door locks, but other accessories or card dispensers are expensive, and when shipping for free, the price of maintenance will be several thousand dollars), and the products are purchased. After a period of time, the manufacturer may not be found, or there are quality problems to find irresponsible manufacturers. The manufacturer believes that improper use of the user leads to no maintenance or high price of accessories. The above phenomenon is even difficult for the court to judge. Even if the user wins the unqualified brand, the company may choose to evade the name of the company. If the brand is not standardized, it may not be worth the loss.
Smart door lock purchase tips
Just because smart door locks are increasingly favored by consumers and hotels, consumers should know more about the common sense of buying smart door locks, so I will teach you how to buy smart door locks today!
1. Be sensitive when the door lock card or sensor key card is used. It is necessary to repeat the continuous card insertion or the induction key card to operate normally after opening the door. There should be no "no reaction" or "error" and "motor rotation" phenomenon. To investigate the information of the brand door lock, the clock is not easy to be confused, as long as the performance of the smart door lock is stable, those so-called additional functions do not necessarily have a practical effect. The door lock of the own error correction function circuit should be selected. If you choose an immature product, you may not be able to use it or maintain a lot of work. Keyu intelligent door lock circuit microcomputer chip control, the circuit comes with information error correction function, which makes the circuit processing information more stable. The sensor door lock adopts double clock correction error rate is very low, and the induction door lock uses wireless data collector for door lock maintenance. It is very convenient to collect the open door record data.
2, the choice of card locks after their first check door lock sensor sensitivity to understand the static power consumption, because the door lock are generally dry batteries, understand the static power door lock is important, now some brands door sensors The four- cell battery can be used continuously for more than one year. Some brands change the battery in less than a month. Frequent battery changes can seriously affect the use.
3. When using the magnetic card door lock, you should know whether the door lock reader is self-developed by the manufacturer to read the card's own encryption algorithm, or use the universal magnetic card reader. If a card is written with a universal card reader, others can copy the card with a universal card reader and cannot achieve confidentiality. Keyu newly introduced IC card plus magnetic card door lock, guest card with magnetic card, administrator and maintenance information with IC card, magnetic card reader's card reader module own encryption algorithm.
4. Select the smart door lock to choose whether the material of the door lock panel and the surface plating are uniform. It is claimed whether the copper plate is made of copper or steel plated. Whether the stainless steel plate uses 304 stainless steel or the price is 2 to 3 times lower. Iron, users can also choose PVD surface treatment. If you choose the plating surface, you should see if there is a protective paint on the surface of the door lock. Keyu has always insisted that the products are real materials, such as the nominal pure copper panel, the handle must be pure copper, such as the nominal 304 stainless steel material must be 304 stainless steel. Pure copper forged is made of imported high quality brass rods. The thickness and weight of the panel can be guaranteed. The plating layer fully meets the salt spray test standard.
5, the door lock presses the handle to open the door lock should be flexible and smooth, there should be no serious "åš“" and "å–³" mechanical friction sound in the lock body. With a light force, you can press the handle and press the handle back to normal. Mechanical transmission can not be fully lubricated by oil. It depends on the connection of mechanical parts. If the oil is fully lubricated, the door lock will fail frequently after the oil is dried for a long time.
6. The lock body of the standard five-lock tongue structure should be selected, and the lock body of the lock body should be driven by a motor. Keyu intelligent door lock body is improved on the basis of the original foreign famous brand lock body. The structure lock body has the highest domestic and external use rate, reasonable structure, low part wear, excellent performance, convenient installation and long service life. The normal service life is more than 15 years, and has been praised by users. The insurance tongue and anti-locking tongue have the functions of anti-insertion and anti-smashing. The square tongue (anti-lock tongue) is applied with a reinforcing structure to effectively prevent the square tongue from breaking or bending when the wind is blown or the door is closed when the door is opened. Keyu's improved reinforced structure of the square tongue is mostly concentrated on the tongue of the thickest tongue (12mm thick), and the distance of the force point is shortened so that the improved square tongue strength is five. More than double. The other brands use the original structure unmodified lock body to distribute a large part of the force to the weakest point of the tongue (3mm thick) position, the square tongue is too strong, the tongue tail is bent, the square tongue can not be fully back to the door lock Can't open it. Don't be misled by other so-called small locks or new locks, because the lock body is modified by the barely installed electronic control part of the structure of the household door lock. Because of the different use environment and the increased frequency of use, the lock is so strong. Poor physical performance and limited life.
7. Cards are divided into IC card, TM card, magnetic card and proximity card. The most used ones are IC card (contact type) and proximity card (non-contact) door lock. IC card door locks generally use Siemens cards (now Shanghai Bay) Ling, Fudan and other cards are compatible). Inductive cards used in proximity card locks mostly use TEMIC cards (many are called inductive IC cards, which can read and write data with a capacity of 33). Hotel sensor door locks generally make TEMIC cards. Philips MF1 card (can be divided into multiple areas to read and write data function capacity of 1000 bytes, large capacity, the price of the card is similar to TEMIC, but the door lock price is much more expensive) Many consumption, attendance, open the card with MF1 card. There is also an ID card (ID card is a string of codes that have been set at the factory, can only read information, can not write information into the card) ID card is generally used in home, apartment smart lock without computer management system, the price of ID card It is about half of the TEMIC card. At present, there are many companies that manufacture cards. Many smart lock factories use smaller card manufacturers to make cards, which cannot guarantee the purchase of chips (many parallel imports of electronic components) and packaging and pattern printing processes.
8. The appearance of the door lock is selected according to the user's hobby and decoration configuration. For example, the hotel recommendation is generally ideal for using a more elegant appearance.
9. Use a whirlwind handle or a non-empty spinner? There is no problem based on years of use. It is recommended to use a non-empty rotary lock body. The non-empty rotary lock body is not affected by the deflection when the panel is installed.
