01. What are the types of mainstream smart locks and what are the differences?
Answer: Smart lock can be divided into semi-automatic smart lock and fully automatic smart lock according to the transmission mode. It can generally be distinguished in the following ways.
Product appearance difference: semi-automatic is generally a handle, fully automatic generally no handle.
The difference in running logic: after the semi-automatic smart lock is authenticated, it needs to press down the handle to open the door, and after going out to close the door, it needs to be locked on the handle. After the fully automatic smart lock is authenticated, the door can be pulled open directly, and after going out and closing the door, it can be automatically locked without other operations.
It should be noted that there is a push-pull lock with a self-rebounding lock body in the automatic smart lock. After it is authenticated, it needs to push the front panel handle to open the door, and the door is automatically locked after closing.
02, there are many ways to biometrically identify smart locks, how should I choose? Can fake fingerprints unlock?
A: At present, there are three mainstream biometric unlocking methods for smart locks, namely fingerprints, faces, and finger veins.
❶ Fingerprint recognition
Smart locks equipped with fingerprint recognition functions have the highest market share, and at the same time, because of the early research on fingerprint recognition technology in China, it has been very mature in application. Fingerprint recognition has the characteristics of high security, high stability and accurate recognition.
At present, the smart lock industry fingerprint unlock mainly uses semiconductor fingerprint head, compared to optical identification, sensitivity, accuracy have been significantly improved, so the so-called use of fake fingerprints on the network to unlock, for the built-in semiconductor fingerprint head of the smart lock, basically invalid.
Therefore, if there are no special requirements for the unlocking method, and users who like a more mature identification method, it is recommended to choose a smart lock that focuses on fingerprint recognition.
❷ Face recognition
The face recognition smart lock mainly scans the user's face portrait through the sensor, and compares it with the facial features entered in advance to complete the authentication.
From the current situation, the face recognition smart lock in the industry basically adopts 3D face recognition technology, which is higher in security and higher accuracy than 2D face technology.
3D face recognition technology mainly has three types of 3D structured light, binocular and TOF, all of which are obtained through different collection methods to obtain user face information.
3D face recognition unlock without direct contact with the door lock, when the user in the detection range, you can automatically open the recognition, the way to open the door is full of technology, like to try fresh technology users, you can choose face recognition smart lock.
❸ Refers to vein recognition
The basic principle of vein recognition is to use the structure of venous blood vessels for identification. Compared with explicit biological information such as fingerprints and faces, the vein information identified by finger veins is hidden deep inside the body, so it is highly secure, cannot be copied, and does not have to worry about being stolen to unlock the lock.
Finger vein unlocking can also take care of some fingerprints are not obvious, fingerprint wear and tear and other users, if there are elderly, children, fingerprint features are not obvious users at home, you can choose the finger vein smart lock.
03. How do I know if my door can be equipped with a smart lock?
Answer: There are many kinds of lock body specifications of the door lock, the same smart lock will also consider most of the lock body specifications on the market and design, in general, you can install smart locks, do not need to change the door, unless a few special or foreign lock body, but also can be installed by changing the door hole.
As long as you want to install a smart lock, you can communicate with the merchant, and the merchant and the universal installation master will help you solve it. In terms of material, smart locks can be installed on wooden doors, iron doors, copper doors, composite doors and anti-theft doors, and even glass doors used by companies can use smart locks.
04. Can the elderly and children use smart locks?
A: It works. The mainland is entering an aging society, and the proportion of the elderly group is gradually increasing. The elderly group has poor memory and inconvenient movement, and smart locks can just solve their needs.
After installing the smart lock, the elderly no longer have to worry about not bringing a key when they go out, even if they don't have to, they don't have to shout for someone to open the lock, and even climb the window into the house to open the door. For special groups such as the elderly and children with shallow fingerprints, a finger vein smart lock can be used.
When the elderly are inconvenient to open the door, whether outside the door or inside the house, it can enable children to open the door for their parents remotely through the app. The smart lock with the function of opening the door record monitoring can enable children to monitor the opening of the door lock of the parents at any time to find abnormal situations at any time.
05. When purchasing smart locks, what should I pay attention to?
A: When consumers choose to buy smart locks, it is recommended to identify from the following points:
❶ When choosing a smart door lock, choose the product that suits you, and do not blindly pursue various peculiar functions and unlocking methods;
❷ Pay attention to the safety of products and the high quality of materials;
❸ Smart door lock products should be purchased through formal channels, and carefully check whether the product packaging is clear and unambiguous, whether it has a certificate of conformity, instruction manual, warranty card, etc.;
❹ To first confirm whether there is a heaven and earth hook in their own door, generally when installing a fully automatic smart lock, it is best to remove the world hook to prevent the smart lock from consuming electricity too fast. After confirming whether there is a heaven and earth hook, communicate with the store or online customer service in time;
❺ Consider whether you pay attention to unlocking noise, if you do not care about the sound factor, you can choose the rear clutch fully automatic, if you care, it is recommended to consider the full automatic lock of the built-in motor, the sound is relatively small.
06. How to arrange the after-sales service of smart lock installation?
A: Most smart locks come with installation services. After the user receives the smart lock, he can call the merchant phone (the general phone will be in the outer packaging, instruction manual, etc.) to make an appointment.
At present, the installation of smart locks still has great professional requirements, so it is not recommended that users install themselves, so consumers must choose brands that provide installation services when purchasing smart locks.
07. Do you want to leave a heaven and earth hook when installing smart door locks?
A: Demolition is recommended. The heaven and earth hook is a "well" shaped structure with the door frame, so that the opening side of the door and the upper and lower sides have a stronger lock, but the protection between the door and the door is strengthened. In terms of anti-theft performance, the security of the heaven and earth hook and the smart door lock has nothing to do with it, as long as the lock body is opened, the sky and earth hook will be opened.
In addition, there are some hidden dangers in the door lock installed on the heaven and earth hook, on the one hand, the number of parts of the heaven and earth hook is increased, and the structure is complex, which not only brings inconvenience during installation, but also increases the failure rate of the door lock. On the other hand, due to the increase in the lock tongue, the force of the lock body is multiplied, the transmission of the entire door lock will produce a great burden, and the long-term loss will weaken the patience, resulting in a change in several years, the cost is high, not to mention, it also brings unnecessary troubles to home life.
Compared with the anti-theft performance of the heaven and earth hook, the anti-theft warning and processing method of the mainstream smart lock can already be comparable to the sky and earth hook.
First of all, the vast majority of smart locks have anti-vandal alarm function, when encountering violent destruction by criminals, you can send early warning information to users. If it is a smart lock with a video function, it can also monitor the situation outside the door at any time, coupled with the human motion detection function of the video lock, it can monitor suspicious people outside the door for 24 hours, and capture images and videos to send to the user, so that the criminals have been discovered before they do it.
08, smart lock is so powerful, why do you have to design the key socket like the traditional mechanical lock?
A: In 2007, the Ministry of Public Security issued the People's Republic of China public safety industry standard "General Technical Conditions for Fingerprint Anti-theft Locks" (GA701-2007), which pointed out that smart locks must have emergency unlocking functions: special methods can be used to take special methods to unlock the special devices of the manufacturing plant; when using mechanical locks to open emergencily, the mechanical lock head should meet the requirements of GA/T73-1994 in the A level. At present, there are three kinds of emergency unlocking methods of smart door locks on the market, namely mechanical key unlocking, dual circuit drive, and password turntable unlocking, and the vast majority of which use spare keys as emergency solutions.
In general, the mechanical lock hole of the smart lock is designed to be relatively hidden. On the one hand, it is for the aesthetics of the product, and on the other hand, because this function is for emergency backup, so it is mostly hidden. Emergency mechanical keys mainly play a key role in the event of a smart lock failure or lack of power, or other special circumstances.
09、 How to maintain the smart door lock?
Answer: In the process of use of smart locks, we must pay attention to product maintenance, there are many precautions,
❶ When the battery of the smart door lock is low, pay attention to replace it.
❷ After the fingerprint collector has moisture or dirt, it should be gently wiped with a dry soft cloth, paying attention to avoid scratches and affecting fingerprint collection. Do not use substances containing alcohol, gasoline, diluents, or other flammable substances for cleaning or maintenance.
❸ When the mechanical key is not used smoothly, a little graphite powder or pencil powder can be smeared in the lock cylinder slot to ensure that the key opens the door properly.
❹ Do not allow the lock face to come into contact with corrosive substances. Also do not use hard objects to collide or knock on the shell to prevent damage to the surface coating or indirectly affect the electronic parts inside the fingerprint lock.
❺ Check frequently. Door lock to be used every day, it is recommended to check once every six months or once a year, while checking whether the battery is leaking, whether the tightening screw is loose to ensure tightening; the gap between the lock body and the lock gusset plate...
❻ Smart locks are basically built-in delicate and complex electronic components, and when disassembled by non-professionals, they may damage internal accessories or cause other serious consequences. If you suspect that there is a problem with the fingerprint lock, it is best to consult a professional after-sales service.
❼ If the automatic lock uses a lithium battery, do not charge the lock directly with the charging treasure, which can easily lead to battery aging, and even explode in severe cases.
10. What should I do if the smart lock is out of power?
A: At present, there are two main types of power supply methods for smart locks: dry batteries and lithium batteries. Smart lock built-in low battery alarm function, daily use of the encounter with insufficient power, will issue an alarm sound, at this time please replace the battery as soon as possible, if it is a lithium battery, please remove the lithium battery to charge.
If you miss the battery replacement time due to going out for a long time, when you encounter an emergency to open the door, use the charging treasure to charge the door lock, and then replace the battery or charge the battery according to the above method.
Note: Lithium batteries can not be mixed under normal circumstances, please use the matching lithium batteries provided by the merchant, or choose as appropriate after consulting a professional.
