Preparing for home: smart door lock purchase skills and misunderstanding analysis

The advent of the smart era, smart home products began to replace traditional home devices, smart door locks are one of them. The door can be opened without a key, and the traditional key is replaced with a mobile phone, and the keys are all in the mobile phone. Smart door locks can indeed bring great convenience to people's lives. However, with the increasing number of smart door locks on the market, in order to catch more consumers, smart door lock manufacturers are unavoidably more while promoting their products. A lot of "exaggerated" ingredients, and these are very likely to cause great misunderstandings for consumers. Regarding the products in the current smart door lock market, consumers should clarify a few points when purchasing products, so as not to enter the misunderstanding.

Smart door lock purchase skills

1. Be sensitive when inserting a door lock or induction key card. Repeatedly inserting the card or the induction key card should operate normally after opening the door, and there should be no "no response" or "error" or "motor rotation". To investigate the information and clock capacity of the brand's door locks, as long as the performance of the smart door lock is stable, those so-called additional functions may not have practical effects. The door lock with its own error correction circuit should be selected. If you choose an immature product, you may not be able to use it or maintenance work is very large. Keyu intelligent door lock circuit is controlled by microcomputer chip. The circuit comes with information error correction function to make the circuit process information more stable. The sensor door lock adopts dual clock correction error rate is extremely low. The sensor door lock uses a wireless data collector for door lock maintenance, It is extremely convenient to collect data of door opening records.

2. Select the induction card door lock, first check its induction sensitivity, and then understand the static power consumption of the induction door lock. Because the general induction door locks are powered by dry batteries, it is important to understand the static power consumption of the induction door locks. Some current brand induction door locks Four batteries can be used continuously for more than one year, and some brands change batteries within a month. Frequent battery replacement will seriously affect the use.

3. When choosing a magnetic card door lock, you should understand whether the card reader of the door lock develops its own encryption algorithm, or whether it uses a general magnetic card reader on the market. If a card written by a universal card reader is used, others can use a universal card reader to copy the card without achieving the security effect. Keyu has launched a new IC card plus magnetic card door lock, a magnetic card for guest cards, an IC card for administrators and maintenance information, and its own encryption algorithm for the card reader module of the magnetic card reader.

4. Choose smart door locks, choose whether the materials of the door lock panels and the surface plating are uniform. It is claimed whether the copper panels are made of copper or steel plates with imitation gold plating, and whether the stainless steel plates are made of 304 stainless steel or stainless steel that is 2 to 3 times lower Iron, users can also choose PVD surface treatment. If the electroplated surface is used, it depends on whether there is seal protection paint on the surface of the door lock. Keyu has always insisted on real products, such as the pure copper panel and the handle must be pure copper, and the 304 stainless steel material must be 304 stainless steel. Imported high-quality brass rods are used for pure copper forging. The thickness and weight of the panel can be guaranteed. The plating layer completely meets the salt spray test standard.

5. The door lock should be flexible and smooth to open the door lock by pressing the handle, and there should be no serious "cracking" or "chattering" mechanical friction in the lock body. It should be possible to press down the handle with a slight force, and the handle returns to normal. The mechanical transmission cannot be relied solely on engine oil lubrication, but must rely on the compact connection of the mechanical parts. For example, if the engine oil is dry after long-term use, the door lock will fail frequently.

6. A lock body with a standard five-bolt structure should be selected, and the lock pin in the lock body should be driven by a motor. Keyu smart door lock body is improved on the basis of the original famous foreign brand lock body. The structural lock body has the highest domestic and foreign usage rate, reasonable structure, low part wear, excellent performance, easy installation and long life. The normal service life of more than 15 years has been well received by users. The safety tongue and anti-locking square tongue have the functions of anti-insertion and anti-prying. The square tongue (anti-lock tongue) should be reinforced to effectively prevent the tongue from breaking or bending when the tongue is opened after the door is opened or when the door is artificially closed. The strength of the square tongue of the improved reinforced structure of Keyu is mostly concentrated on the position of the thickest tongue (12mm thick) of the square tongue, and the distance of the force point is shortened a lot, making the improved square tongue stronger. More than times. While other brands use the lock body with the original structure that is not improved, a large part of the force is distributed to the weakest point of the tongue (3mm thick), the tongue is bent too much, and the tail of the tongue is bent to form the square tongue. It cannot be turned on. Don't be misled by other so-called small lock bodies or new lock bodies, because that kind of lock body is renovated in the structure of household door locks with barely adding electric control parts. Because of the different use environment and the increased use frequency, this kind of lock Poor physical performance and limited life.

7. Cards are divided into IC cards, TM cards, magnetic cards, and induction cards. The most commonly used are IC card (contact) and induction card (non-contact) door locks. IC card door locks generally use Siemens cards (now there are Shanghai Bay Ling, Fudan and other cards are compatible). Inductive card door locks mostly use TEMIC cards (many called inductive IC cards, which can read and write data with a capacity of 33 digits). Hotel inductive door locks generally use TEMIC cards. Philips MF1 card (capacity for reading and writing data in multiple areas is 1000 bytes, large capacity, the price of the card is similar to TEMIC but the price of the door lock is much more expensive) MF1 card for many consumption, attendance, open the card. There is also an ID card (ID induction card is a series of codes that have been set before leaving the factory and can only read information, not write information into the card) ID cards are generally used in home and apartment smart locks without a computer management system. The price of ID cards It is about half of the TEMIC card. At present, there are many card manufacturers. Many smart lock factories use smaller card manufacturers to make cards. They cannot guarantee the purchase of chips (many parallel electronic components) and packaging and pattern printing processes.

8. The appearance of the door lock is selected according to the user's preferences and decoration configuration. For hotels, it is recommended to choose the more dignified appearance.

9. Do you use air spin handle or non-air spin handle? No problem based on years of use. It is recommended to use a non-empty twist-lock body. The non-empty twist-lock body is not affected by the deflection of the panel installation and will affect the door opening.
