Buy smart locks should pay attention to those

In today's society, “smartness” is not limited to the human brain. Related researchers have begun to explore the intelligence of various machines and have continued to penetrate people’s lives. Doors and windows as the first line of safety at home, along with people's increasing awareness of security, since the 1980s and 1990s, security doors, wooden doors gradually rise, with the continuous development of security technology, now with the emergence of smart doors and windows products, intelligent The door lock will become the "first patron saint" of home security. When buying smart locks, you should pay attention to the following points:

1, the appearance of the lock on the basis of the user's preferences and decorative configuration choices, such as the hotel generally use the proposal to choose a more serious look is the ideal.

2. Using a spinning handle or a non-rotating handle? No problem based on years of use. It is recommended to use a non-rotating lock body. The non-rotating lock body is not affected by the deflection of the panel when installed.

3. Selecting the induction card door lock firstly checks its sensing sensitivity and then knows the static power consumption of the sensing door lock. Because the general sensing door locks are powered by dry batteries, it is very important to understand the static power consumption of the sensing door locks. Some of the current brands of door locks The four batteries can be used continuously for more than one year, and some brands replace the battery in less than a month. Frequent battery replacement will seriously affect the use.

4. When selecting the magnetic card door lock, it should be understood whether the door lock reader is a self-developed card reader's own encryption algorithm, or uses a magnetic card reader head that is commonly used in the market. If a card is written using a universal card reader, others can use a universal card reader to copy the card without achieving confidentiality. Keyu newly launched 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.

5. When the door lock is pressed and the handle is opened, the door lock should be flexible and smooth, and there should be no serious "click" and "click" mechanical friction sound in the lock body. With gentle force, you should be able to press the handle and return to normal. Mechanical transmission can not rely on oil lubrication, depends on the mechanical connection is compact, such as relying on oil lubrication Once the oil is dry after prolonged use, the door lock fault frequently.

6, when the card lock or induction key card sensitive. If you want to insert the card repeatedly or the key card is open, you should run normally. There should be no "no response" or "error" or "motor rotation" phenomenon. To investigate the content of the brand's door lock is not easy to mess, as long as the check smart door lock performance is stable, those so-called additional features may not have a practical effect. The door lock of the self-correction function circuit should be selected. If you choose an immature product, you may not be able to use or maintain it. Keyu intelligent door lock circuit microcomputer chip control, the circuit comes with information error correction function, so that the circuit processing information is more stable, the sensor door lock adopts dual clock correction error rate is very low, the sensor door lock adopts wireless data collector for door lock maintenance, It is very convenient to collect open record data.

7, to use the standard five-bolt structure of the lock body, the lock body lock motor drive. Keyu intelligent door lock lock body is improved on the basis of the original foreign famous brand lock body. The structure lock body has the highest utilization rate at home and abroad. The structure is reasonable, the parts wear degree is low, the performance is excellent, the installation is convenient, and the service life is long. , The normal service life of more than fifteen years, has been praised by users, insurance tongue, anti-locking large tongue, etc. with anti-plug, anti-smashing function. The square tongue (anti-lock tongue) applies a reinforced structure to effectively prevent the tongue from breaking or bending when the tongue is opened at the back of the door or when the door is closed. The improved strength of the square tongue of the improved structure is mainly concentrated on the tongue with the thickest tongue (12mm thick), and the distance of the force point is shortened so that the improved square tongue strength is greatly improved. More than times. While other brands use the original structure of the lock body is not improved to a large part of the tongue to the weakest point of the tail (3mm thick) position, the tongue is too much force behind the tongue and the end of the tongue bent can not be fully back to the door lock It cannot be opened. Do not be misled by other so-called small locks or new types of locks, because the kind of locks are remodeled when the structure of the home door locks is barely installed with an electronic control part. This type of lock is used due to the different usage environment and the frequent use frequency. Poor physical performance and limited life.

8, the card is divided into IC card, tm card, magnetic card, proximity card, now the most used is the ic card (contact) and proximity card (non-contact) door lock, ic card lock generally use Siemens card (now Shanghai Bay Ling, Fudan and other cards compatible). Most of the sensor cards used in the proximity card door locks have temic cards (many call induction cards, which can read and write data with a capacity of 33 bits), and hotel inductive door locks generally make temic cards. Phillips mf1 card (can be divided into multiple districts to read and write data function capacity of 1,000 bytes, large capacity, card prices and temic almost but the price of a lot of expensive locks) a lot of consumer, attendance, open card with mf1 card. There id card (id card is a set of code before leaving the factory, can only read information, can not write information into the card) id card is generally used in home and apartment without a computer management system smart lock, id card price It is about half of the temic card. At present, there are many enterprises that manufacture cards. Many smart lock manufacturers use smaller card factory cards, and cannot guarantee the purchase of chips (parallel imports of electronic components) and packaging and pattern printing processes.
