When many people travel, in addition to the local beauty, the most impressive thing is the door lock of the hotel. Compared with ordinary door locks installed by home users, the smart door locks installed in hotels give people a very convenient and safe feeling. Of course, in addition to hotels, many home users in first- and second-tier cities have also begun to upgrade their home door locks and replace them with smart door locks with a higher safety factor.
However, at present, consumers' understanding of smart locks is limited to the functions of password unlocking and fingerprint unlocking. When purchasing similar products, the models recommended or used by stars play an important guiding role. Many friends are even more worried about purchasing a Smart Lock. Are smart locks really smart? How does it usually work, how do we charge it and open the door when we are outside the door when it runs out of power. Today, we will talk about these issues, and interested friends may wish to take a look.
1. The working principle of smart lock
Knowing how a smart lock works allows users to better understand it. The basic structure of the smart lock is to use the motor to drive the mechanical lock cylinder to complete the action of manually turning the key. Smart locks are the product of the combination of traditional door locks, electronic information technology, biometric identification technology, and Internet of Things technology. , At the same time, it is more perfect in the security alarm of the door lock.
When the traditional door lock opens the door, it needs to take out the key, insert the key, rotate 3 times, pull out the key, and open the door, a total of 7 actions; while the smart lock only needs to identify the fingerprint, open the door, a total of 2 actions. When the traditional door lock is closed, it needs to close the door, take out the key, insert the key, rotate 3 times, and pull out the key, a total of 7 actions; while the smart lock only needs 1-2 actions, close the door or close the door and lift the lock. The smart lock reduces the door opening action by 5 and the door closing action by 5-6, making a great leap in convenience.
2. How to open the door when the smart lock is out of power
1. USB emergency power supply
When the Smart Door Lock is working, it needs electricity to start the door. If one day, it reminds you to replace the battery or charge, you are too busy to ignore this matter. After we get off work and are locked out, we can use USB to charge the door lock. Now, many people will carry USB and power bank with them, which is a good habit. We connect the USB link cable to the USB power supply hole of the smart door lock, and then connect the other end to the power bank to provide emergency power supply to the door lock. At that time, you can open the door by entering your fingerprint or password.
Under normal circumstances, the smart door will generate a low-voltage alarm prompt, such as a "beep, beep, beep" alarm prompt, which is a reminder to the user that the door lock power is insufficient and the door lock battery needs to be replaced in time. To install the battery, you need to know the location of the battery, generally in the following locations: the rear panel, on the lock body, and centralized power supply. Most smart door locks have built-in 5 pairs of batteries. According to the number of times the door is opened and closed for a family of three, there is no problem in about one year. If there is a power shortage alarm, you need to replace the battery or charge it in time.
2. Mechanical key to open the door
Smart door locks support multiple unlocking methods, among which the key is their standard configuration. If you encounter a situation where the smart lock is out of power and cannot open the door, then you need to open the door mechanically with a key. The keyhole of the smart door lock is either in the lower middle part of the front panel or at the bottom of the front panel. When you use a smart lock, remember to put the emergency key in the office, in the car or with a close neighbor, in case it is the only one.
3. Find a locksmith to unlock the lock
One of the reasons why smart door locks are safer than ordinary door locks is that they mostly use C-class lock cylinders. This level of lock cylinder is difficult to be unlocked by technology, but it does not mean that it cannot be unlocked by technology, but it is more troublesome and requires you to spend extra money.
At present, the intelligence of a smart door lock lies not only in its convenient unlocking method, but also in its security function. Now many smart locks have an alarm function. When the door lock is picked up, the password is continuously wrong, and the fingerprint is continuously recognized incorrectly, the door lock will directly emit a sharp alarm sound to remind family members to pay attention to the "coming" of the thief. Smart locks with networking capabilities will also push messages to mobile phones, so that householders who are outside can also dispose of them in time to avoid property damage. Smart door locks are easy to use, but if you have a purchase plan, it is recommended that you start with products from big brands.
