Class C lock core, 6 ways to open the door.

In the past two years, the smart lock market has been very chaotic. The cheapest smart fingerprint lock is less than 1000 yuan. How dare you? Seeing such a cheap price, most people will be moved, but think about it carefully. Just a C-class lock core will be close to 300 yuan. Is a thousand-yuan smart lock really safe? I almost started with a fingerprint lock of around 1000 yuan. Fortunately, the incident that Tesla coil black box was unlocked for 3 seconds some time ago was a blow to me. Later, when I chose the fingerprint lock, I was more cautious. Comparing the security and convenience of the half-day lock, the tabby cat W500 fingerprint lock for the Internet of Things was finally selected.

When I chose this lock at that time, I paid attention to both safety and convenience. According to relevant national regulations, smart locks must have mechanical keys to meet emergency needs. Therefore, a weakness of the smart lock is the mechanical lock core. Many smart locks on the market, especially some cheap smart locks, still stay in the B-class lock core, and this one uses the C-class lock core; On the other hand, this smart lock can resist the small black box of Tesla coil and is safer in the electronic part.

Convenience mainly considers that the lock can be unlocked in many ways. For example, if the daughter-in-law has a shallow fingerprint, she can use her mobile phone Bluetooth to unlock it and unlock the password. Parents are old, come here occasionally, can't remember the password, can't use a smart phone, and can use a physical magnetic card to unlock it; When there is no one at home, if there is a courier, you can unlock the courier remotely through the APP. After careful calculation, it is really convenient to take into account all kinds of usage scenarios.

The packaging of the spotted cat W500 IoT fingerprint lock is as shown above. Although the design is relatively simple, it is very heavy, and the weight is particularly sufficient. After opening the package, there is a warranty card, installation instructions and instructions for use. The door lock panel is red bronze, which looks more advanced than black and silver. This color scheme matches the security door at home.

After receiving the lock, I will contact the after-sales installation immediately. Installation is free. At about 2 pm, before the installation master came to the door, I opened the package and looked at it carefully. The fingerprint lock of the Internet of Things has many accessories. Different types of screws are packaged separately, the guide vanes are made of alloy steel, and the inner and outer panels are also provided with protective gaskets.

The smart lock also comes standard with two emergency mechanical keys and two magnetic keys. The magnetic key should be an NFC chip. I wanted to copy the magnetic key to my mobile phone, but I couldn't recognize it after trying it with Huawei and Apple. It is estimated that nonstandard frequencies are used or other encryption technologies are adopted. The advantage is that the risk that the disk is easily copied is eliminated.

At the bottom of the outer panel are mechanical keyhole and USB power interface, both of which are integrated design, with high safety and will not be easily tilted and opened. When the battery of the smart lock is low, if the mechanical key is not at hand, you can use the mobile power supply to power the lock through the USB interface.

Both the outer panel and the inner panel support the function of adjusting the handle left and right. The direction of the lock handle can be adjusted through the small hole on the right side, and both the left and right doors can be adjusted.

The panel of the lock is heavy and the material is thick. The surface of the panel adopts IMD technology, which has good color and luminosity, good dust-proof, moisture-proof and scratch-proof effects, so there is no need to worry about scratching the panel in a short time.

There is a cushion when the panel is installed, which can make the panel of the door lock fit the door better and prevent the panel from scratching the surface of the door.

My parents' smart lock slides every time they need fingerprints, which is more troublesome to use. Spotted cat adopts the integrated design of fingerprint and handle, which is very convenient and does not need to press the fingerprint when opening the door.

The upper part of the panel is the password input area and the disk sensing area.

The inner panel of the door has the same appearance as the outer panel. Slightly different, the password area in the upper part has become a battery compartment, and the spotted cat LOGO in the lower part has become an anti-lock mechanism.

The Internet of Things fingerprint lock spotted cat is powered by 8 batteries, and batteries are provided in the accessories. According to the official propaganda, the battery life is 180 days, and the battery can be replaced once a year. When the battery charge is less than 20%, the smart lock will actively remind the user to replace it in time through the APP and the lock body.

The material of the spotted cat's lock body is very thick, and the lock body alone weighs 1KG. The lock body supports the heaven and earth hook of the security door, so you can pay attention to it when installing.

The lock tongue can also be adjusted by 180 degrees, which is also suitable for opening doors left and right. The lock tongue adopts hook design, which can prevent the card from unlocking and further improve the safety.

At 2 o'clock in the afternoon, the installation master came on time, presented all kinds of certificates and started the installation. This master is an old driver at first sight, and he is very skilled. He drilled a hole, divided by three times five, and then installed it. After the installation, at my request, the master specially took out the black box of Tesla coil to help me verify the safety on the spot. This lock has withstood the electromagnetic interference of a 360-degree black box with no dead angle, so the electronic safety is also relieved.

After installation, the effect looks beautiful. Red bronze color matching with security doors looks more upscale.

Just put your finger on the fingerprint when unlocking the car door, and the reaction time is about 1 second. After a drop, a voice reminds you that the door lock has been opened. The unlocking process is smooth and natural. It has been used for nearly three months now, and it can be opened almost once whether it is dry or wet, and no adjustment is needed. By the way, fingerprints will become more sensitive after being used for a long time, which is a self-learning mechanism of fingerprints.

Daughter-in-law's fingerprint is very shallow, so she can only unlock it with a password. Every time she needs to enter a password, the touch panel can wake up the key light. Because the password supports 16-digit password, as long as the input number contains complete and continuous correct password, the lock can be unlocked. This is convenient and safe to operate, and the door lock also supports setting a set of mandatory passwords. When this password is entered, the door lock will immediately alarm the family.

In addition to the physical password, the door lock can also be unlocked by entering the password through Bluetooth +APP.

What should the elderly do if they are forgetful and have shallow fingerprints and can't use smart phones? Don't worry, you can also unlock it with a floppy disk. The floppy disk needs to be paired with the fingerprint lock once before it can be enabled.

The floppy disk is very small and can be easily put into the protective case of the mobile phone. We carry mobile phones with us, so we don't have to worry about forgetting to bring floppy disks when we go out.

You can easily open the door lock by putting the disk in the mobile phone case.

Let's look at the effect inside the door. There is an anti-lock device inside the door. Anti-lock is mainly to prevent the cat's eye from unlocking. After the lock is locked, it is impossible to open the door outside unless it is manually unlocked.

There is no need to mention this, but after Redmi's smart door lock is locked, it is embarrassing to unlock the lock mechanism outside the door. Locking is originally to prevent unlocking from the outside. I don't know what the significance of Mijia's doing this is. From this point of view, tabby cats have a higher safety factor.

The design of Spotted Cat's APP also takes security and convenience into consideration. Every time you enter the APP, you need to verify it to prevent illegal operation or misuse by criminals when they use it. When logging in, you can choose to use the fingerprint already entered in your mobile phone without entering a password, which is really convenient.

Users of smart locks can be managed in the APP, and different users can be assigned different permissions and unlocking methods. In addition to simple fingerprint, password and magnetic card, the unlocking method can also be set as a mixed authentication method, so it is necessary to go through two ways at the same time before opening the door. For example, the unlocking method you set for your parents is floppy disk+password, and others will not open the door if they find the floppy disk, because they can't guess the password, and the security is further improved.

The smart lock will automatically record to remind you to unlock. In addition to prompting in the APP, users can also bind WeChat and remind them through WeChat. Then, I mentioned the mandatory password earlier. If a family member is threatened, it can be unlocked with a preset mandatory password. At the same time, the APP will remind family members, and the mobile phone will receive SMS reminders. In case the door lock is damaged, the lock will give an alarm sound, and the APP and registered mobile phone number will also receive a reminder push.

Spotted Cat APP can actually manage all its smart devices, such as fingerprint locks, cameras, cat eyes, gateways, door and window sensors, human body sensors, curtains, sockets, switches and so on. And these devices can also be set in linkage. After linkage, a relatively complete smart home system can be built. For a simple example, I set the cat's eye to take pictures when my wife and I unlock the door, and the camera in the living room will turn off the video mode. If the lock is unlocked at night, the intelligent switch will also turn on the lights in the living room and the book bathroom. This is just a very simple example, and you can also customize the scene according to your actual needs.

By the way, at present, Spotted Cat's smart devices also support voice control through Tmall Elf and Baidu speakers. If you have a smart speaker at home, it will be more convenient to use.

Ok, finally, I will summarize the spotted cat W500 IOT fingerprint lock from three aspects. The first priority must be safety. Spotted cat locks have many designs in terms of safety, such as heavy lock body material, C-class lock core, anti-pick alarm, forced alarm, anti-lock and cat-eye unlocking, and the combination of the two methods.

The second aspect is convenience. The combination of door handle and fingerprint makes it easier to unlock. The six unlocking methods meet the needs of different scenes of family members, especially the magnetic card unlocking method, which is convenient for special users such as shallow fingerprints and the elderly.

The last point is the icing on the cake design. The appearance of the spotted cat W500 IoT fingerprint lock is really high-end. Touching my conscience, the male mold design used by some brands of fingerprint locks looks very LOW, and a bunch of posts about the coating technology of the reaction lock handle are posted on the forum. The handle has been used inside and out for a while, and the paint has fallen off. Who says who knows?
