School hasn’t started in the last six months, and I’ve been working from home. The door lock at home used to be very stuck and not very safe. Therefore, I have always wanted to change a smart door lock for my home. I have to consider more points and take care of some needs of my parents. This time, I experienced the full-automatic electronic cat’s eye lock Q3M, which Xiaomi has put on the shelves, and it still made me satisfied.
The appearance of the product is very business-like. I think it is more beautiful than the one with the door handle. Moreover, most smart locks with the door handle have to be pressed again after recognition, and the door will automatically open after recognition by Xiaodi Q3M. Pure black panel design, there is a doorbell button area on the front, and the camera is on the top. The function of the camera will be described in detail below.
The touch panel is the password input area, and the top line of the input area is locking the door and displaying the power, so it is safer to see the power every time.
There are many ways to open the door, such as password, fingerprint, mobile phone or physical key. There’s nothing to say about entering the password.
The fingerprint recognition area is behind the handle, and it has a hidden design, which can have a good protection function. At the same time, no matter whether the left or right hand opens the door, the index finger can touch this area well, and it can be done with one action of unlocking and opening the door, and the recognition speed and accuracy are still good.
The mobile phone can be unlocked in the APP or in the WeChat applet. At the same time, you can authorize to open the door. In the applet, send the authorized temporary key to your WeChat friend, and the other party can open the door directly. The timeliness of the temporary key can also be set.
Finally, I want to talk about this physical key, many automatic electronic locks. The principle is to open the door in one step through the electronic automatic lock body, but it needs to be replaced by an electronic lock body, and it can’t drive the hook between heaven and earth. Xiaodi Q3M still uses the original mechanical door lock, which is unlocked by the great torque of the motor. The life of the mechanical door lock is longer, and it can also drive the hook between heaven and earth. The most important thing is that my parents have never been exposed to smart door locks before, and it is a psychological comfort to have a key.
The indoor part is mainly divided into three areas, the bottom is the safety knob, and the middle is the electronic lock, the lock and unlock buttons. At the top is a rotating handle to prevent the door lock from being dead or in an emergency. Usually, in fact, my parents use this knob more often, so they can open the door by turning it.
The next thing I want to talk about is this electronic cat’s eye. Our family didn’t have a cat’s eye originally, mainly because my mother added a thick cushion to the doors according to the traditional aesthetics in Northeast China, which is actually very unsafe.
The cat’s eye of Xiaodi Q3M is well designed, and the angle is just right to photograph the face. In the mobile APP, you can also take photos or record a small video for 10s, and leave evidence in case of emergency. At the same time, when we click the doorbell outdoors, we can also use the APP for intercom. Video images and sounds are displayed on the mobile phone, which is more secure.
The setting is relatively simple. You can change the unlocking information such as fingerprints and passwords in Xiaodi Butler APP. If you are an administrator, you can also add users, set the torque and other functions, upgrade the firmware, and check the door opening record.
In terms of battery life, Xiaodi Q3M is powered by dual batteries, and the battery of door lock is 5000mAh, which seems to be rare in the industry. The power supply of cat’s eye is 2400mAh, and the battery life level should be good. The door lock will also give voice prompts when the power is insufficient. There is also a hidden USB interface in the outdoor door lock part just in case.
I think the battery charging method is very good, too. I thought that these two batteries might need a special charger or something, which is more painful and needs to be kept, but Xiaodi Q3M directly made two Micro-USB interfaces on the battery, and data lines can be found all over the street, which is more convenient.
The last thing I want to talk about is safety, which is also a problem that my parents are very worried about before changing the door lock. Xiaodi is a door lock company owned by Deschman, so I won’t say much about Deschman’s introduction. What are the top ten brands of fingerprint locks in China, various safety standards and various patents? There are also security functions at the software level. For example, my father made several mistakes in fingerprint identification to verify that it was unreliable, and the door lock was locked out for three minutes. At the same time, my mother and I both received text messages. At the same time, the door lock is also protected by structure, electronic protection and chip protection, and there are alarm fingerprints, alarm passwords and so on in the APP.
If you are an office worker who lives alone, you often forget whether you have locked the door or not, and you can also set up automatic locking at regular intervals.
The after-sales service is also good. It is said that it covers 98% of the counties. Like my current third-and fourth-tier cities, you can make an appointment at any time. I made an appointment the night the door lock arrived, and there was a master the next morning.
