Intelligent door locks are divided into IC card door locks ( plug-in type ) , magnetic card door locks ( plug-in type ) , induction card door locks and TM card door locks. 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% . It is best to understand 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.
Â
 Therefore, you should pay attention to the following points when purchasing smart door locks:
 Â
1. Is the card running normally when the card is continuously inserted or brushed?
 If the card is repeatedly inserted or the magnetic card is opened normally, there should be no such phenomenon as “no responseâ€, “error†or “motor rotationâ€. 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.
Â
2 , select the induction card door lock first check its sensing sensitivity and then understand the static power consumption of the sensor 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. At present, some brands of induction door locks can be used continuously for more than one year, and some brands change batteries in less than one month. Frequent battery changes can seriously affect the use. Keyu induction door lock multi-line technology is the industry leading level, static power consumption is 10uA, and four 7th dry batteries can be used continuously for more than one year. Keyu induction door lock adopts infrared sensor recognition to card two-stage power-on mode. This power-on mode is the most stable induction power-on mode. The largest domestic brands use this power-on mode. At present, some brands use electromagnetic wave recognition. When the card is powered on, the power consumption of the electromagnetic wave power-on mode is larger, because the infrared tube is less in this way, and the weaker signal is continuously transmitted by the antenna (the signal cannot be transmitted because the long-term strong signal consumes a large amount of power). card. Because different panel materials (general door locks will have copper, alloy, stainless steel and other material panels, and there are many kinds of plating treatments such as gold, silver, chrome, etc.), the weaker signals will become more difficult to control. The power of the transmission causes the existing electromagnetic wave to be powered on. The advantage of the electromagnetic wave power-on mode is that the card can be powered in pure black, but the black card of the infrared power-on card cannot be powered directly. Because pure black does not reflect infrared rays, it is recommended to use the infrared power-on method for stability. The card is not printed on the whole surface of pure black. It can be printed on the whole surface in gray and black. In fact, very few customers choose the whole surface. Black is the background color of the card.
Â
3. When using fingerprint lock, you should understand the fingerprint capture system of the door lock.
When using a fingerprint lock, you should know whether the fingerprint acquisition system uses an optical fingerprint acquisition system, a semiconductor fingerprint acquisition system, or an ultrasonic fingerprint acquisition system. Among them, the optical fingerprint acquisition system used by Keyu Huaneng is most suitable for the use of the door lock environment. Compared with other acquisition systems, the optical acquisition system has strong anti-static ability, good system stability and long service life . It can provide high-resolution images and achieve fingerprint image acquisition in a large area.
Â
4 , the choice of intelligent door lock should use the material of the door lock panel and the surface plating is uniform
 At the time of purchase, it is claimed that the copper panel is made of copper or steel plated with imitation gold, and the stainless steel plate is made of 304 stainless steel or ordinary stainless steel which is 2 to 3 times lower in price. Users can also choose PVD surface treatment, PVD surface treatment for 15 years without fading. If you choose a common plating surface, you should see if there is a protective paint on the surface of the door lock. Branch margin products Huaneng has always insisted real materials, such as nominal copper panel, the handle must be pure copper, as a nominal 304 stainless steel must be 304 stainless steel. Pure copper forged is made of imported high quality brass rods. PVD can illuminate the edges of the sand. The thickness and weight of the panel can be guaranteed. The plating layer fully meets the salt spray test standard. It is generally recommended that users use surface treatments with PVD , sand chrome, and stainless steel. And developed a precision cast stainless steel panel. After the door lock is installed for three or five years, the door lock is still as bright as new.
Â
5 , press the handle to open the door lock is flexible, smooth
 There should be no serious "嚓" and "喳" mechanical friction in the lock body. Gently, you should be able to press the handle and return the handle 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.
Â
6. It is necessary to select whether there is a lock body with a standard five-lock tongue structure, and the lock body of the lock body should be driven by a motor.
    Selection lock whether standard five Bolt, tamper whether the insurance tongue and generous tongue locked room and emergency mechanical key to open the door. Branch-Huaneng Standard latch is used, high-performance motor-driven latch, each latch has a signal switching operation of the recording operation, and recording with the mechanical key to open the door. In addition, Keyu uses a unique coil spring drive lock mechanism to improve the stability of the lock pin compared to other parallel springs.

Keyu Huaneng hopes that these things will help you when you buy smart door locks!
