Evaluation of Xiaomi Mijia Smart rearview mirror with more mature functions

Before the IT 168 evaluation, before there was no Mijia smart rearview mirror, my interior environment was like this:

Although it looks well-equipped, the more things in the car, the more chaotic it is, which also blocks the line of sight of driving. Look at these "old buddies" from time to time every time you drive, not to mention how busy you are. Most importantly, any equipment with a little problem will make me very upset.

So I once bought a smart rearview mirror with many functions, but in the end, because of its immature functions, it often crashed and the mirror reflectivity was poor, and I switched back to my "old buddy".

However, recently, I saw that Xiaomi Eco-chain launched the Xiaomi home smart rearview mirror. Since everything I have experienced before is not bad, I will take it to experience it.

This rearview mirror is equipped with MAI OS in-vehicle intelligent interactive system based on Android deep customization, with many built-in apps, and the interface is more in line with the scene inside the car and the habits of domestic users.

Xiaomi integrated all the equipment I needed in the car into the rearview mirror. For example, it can realize navigation, electronic dog, 4G WIFI hotspot, driving assistance, driving recorder, media player, Bluetooth phone, voice assistant and other functions. It looks tough on the surface, but how to actually experience it is another matter. As for whether my "old buddy" can be completely replaced, after a week, I have the answer in my heart. Let me share it with you.

Because this product has so many functions, there may be more articles today. I just hope everyone can know more about this product.

Overview of features:

1. Cost-effective and powerful:

The price of 999 yuan integrates car navigation, cloud electronic dog, 4G WIFI hotspot, intelligent voice assistant, driver assistance, driving recorder, media player, Bluetooth phone and other functions.

2. Beautiful, wide mirror field of vision and high reflectivity;

Mirrors are more beautiful than the original glasses, with wider field of vision at night and high specular reflectivity. It looks clearer than my original mirror (in the screen saver mode), and because the screen can automatically control the brightness, turning on the screen will hardly affect the mirror observation.

3. The system is stable and there is no crash:

It takes about a week to drive to and from work every day, and there has never been a crash.

4. Good touch screen operation:

Equipped with a 6.86-inch IPS touch screen, the touch operation is as smooth as using a tablet or a mobile phone, but the disadvantage is that it is easier to leave fingerprints.

5. Clear the screen:

The color, contrast and brightness of IPS touch screen are good. When the light is strong during the day, the screen looks quite clear, and it will automatically darken at night without glare.

6. Safe operation, completely free hands:

Built-in "Little Love Classmate" intelligent voice, you can close the screen, increase the volume, shoot videos, navigate, order songs, make phone calls and other command operations with just one sentence. With the firmware update in the future, Xiao Ai will grow up with me like a co-pilot.

7. The driving record video is clear:

Using Sony starlight night vision sensor+super wide-angle large aperture lens, you can capture the vehicle license plate number within 5M distance during the day, and the night shooting effect is also very good, and you can capture the details of the road at night.

8. Support 4G full netcom and dual-band WIFI connection:

It can be used as a 4G hotspot, providing a WIFI environment for the car, and also supporting dual-band WIFI connection to access other hotspots.

9. Support GPS/GLONASS/ Beidou three-mode positioning with good signal;

Built-in high-tech map navigation, the use experience is the same as the mobile phone version of high-tech, you can also download offline maps and update the map package at any time. The data of cloud electronic dog comes from the network and will be updated at any time, which is more accurate, but it is estimated that the mobile probe can not detect it (undetermined).

10.ADAS Senior Driver Assistant:

When the vehicle is too close to the preceding vehicle, a collision warning prompt will be issued. When the estimated collision time is less than 1.2 seconds, an animated icon will be displayed in the voice and screen saver interface.

1 1. It can be linked with Mijia Smart Home to control the smart home in the car;

After installing the plug-in through Mijia APP, Xiaomi Mijia smart rearview mirror can be linked with IOT smart home to control smart home.

Appearance and basic configuration: rich in functions and powerful in parameters.

In terms of parameters, Xiaomi Mijia's smart rearview mirror adopts MT8665 quad-core 1.5GPS/ processor, MAIOS vehicle-mounted system based on Android, Sony IMX29 1 photosensitive device, 150 F 1.8 large aperture wide-angle lens, and.

▲ The accessories in the package are relatively simple, such as Mijia smart rearview mirror, Type-C socket cigarette lighter power supply, wrench and instruction manual.

The top of Mijia smart rearview mirror is equipped with Type-C power interface, AUX interface (which can be connected to the car audio system) and AV/IN interface (reserved for the rear camera). This interface can be used to connect other driving recorders, and supports double recording before and after+reversing images.

Mijia intelligent rearview mirror adopts IMX29 1 image sensor of Sony STARVIS series, and the pixel is 1920* 1080, with a single pixel reaching 2.9μm, which can capture more light in low light and improve the night shooting effect.

The lens adopts F 1.8 large aperture, and six groups of all-glass spherical lenses, each of which is coated with 9 layers, which can reduce glare compared with other lenses. The ultra-wide angle of 150 can basically cover the first three groups of lanes (followed by measured videos and pictures).

Several rearview mirrors used before often crashed because of system optimization and poor heat dissipation.

First of all, Xiaomi's smart rearview mirror processor has low power consumption and less heat dissipation. Then in the heat dissipation configuration, all the heat comes from the rearview mirror, which looks like a fence. It has been used normally for a week, even in the case of direct sunlight at noon, there has been no crash, which is very stable.

The bottom of the fuselage is equipped with a pluggable SIM card slot. Plug in your own SIM card and you can use it online, and it supports 4G full netcom. More intimately, after purchasing Xiaomi Mijia smart rearview mirror, you can get Xiaomi Mobile's Milian card and 500MB/ month, and you can also enjoy free firmware upgrade and download the upgrade package for free.

Of course, after the card is connected to the 4G network, we can also use the rearview mirror as a WIFI hotspot, so for example, I specially booked a 10G monthly flow card for it, and I don't feel a loss, because after the family went out to play on weekends and brought their relatives and friends to your car, I told them that you had WIFI in your car, so it felt much better. Then, if you don't want to plug in a card, it can surf the Internet like a mobile phone and support dual-band WIFI connection.

Installation: 5 simple steps, 5 minutes.

▲ Let's compare the original rearview mirror (me) in my car.

The first step is to turn on your mobile phone at home (the measured charging treasure can also power the rearview mirror), bind your mobile phone according to the instructions (you need to download the mobile APP), and then connect your own WIFI to update the offline map, which can save a lot of traffic.

Bind the phone, download the map, and you can install it in the car. Installation is actually very simple. Just tie the rearview mirror to the original rearview mirror with the strap on the rearview mirror, as shown above.

Step 2, plug in the Type-C power supply.

The third step, wiring, is actually very casual, because the wires are long enough, as long as you feel beautiful and tidy.

Step 4, plug the power supply into the cigarette lighter. It is better that this rearview mirror cigarette lighter is equipped with a USB charging port, which does not occupy the space of the cigarette lighter and can charge our mobile phones and other equipment.

Step 5, adjust the camera to a suitable position.

After installation, it is like this. Take a look, the field of vision is really much wider than before, and the specular reflection effect is also quite good.

Even if the screen is turned on (in the screen saver mode), it will not affect the situation behind the observation. Judging from the mirror reflectivity and transmittance, this rearview mirror of Xiaomi can completely replace the rearview mirror of my original car.

Customized Gaode map, cloud electronic dog

Xiaomi smart rearview mirror presented a 500MB/ month, three-month flow card, which can update the offline map of Gaode at any time. Of course, if you are not connected to the internet, as long as you have an offline map, the navigation function is completely available. GPS has three frequencies (GPS, Beidou and GLONASS), and we can choose two of them (GPS+ Beidou or GPS+GLONASS), so the satellite signal is very stable.

The picture above shows the screen saver mode after navigation is turned on. This interface does not affect the rearview mirror observation, but also can see navigation, time, air quality, telephone and other information.

The navigation experience is the same as that on my mobile phone, and the driving recorder and other functions are not affected during navigation (as long as the rearview mirror is turned on, it will automatically start recording).

Navigation interface Compared with my previous navigator (lower right corner), the map of Gaode used in Mijia rearview mirror is more detailed, and the observation distance is closer to my naked eye, making it easier to observe.

Generally speaking, the integrated navigation function of Xiaomi Mijia smart rearview mirror can completely replace the professional navigation equipment I used before.

Driving record: extremely reliable

Xiaomi Mijia smart rearview mirror is equipped with Sony starlight night vision series image sensor, which can shoot 1080P video, and with F 1.8 aperture super wide-angle large aperture lens, vehicle details and road details can be clearly seen in the case of backlight during the day (vehicle license plate number can be photographed within 5M).

The effect of night shooting is also very good, which can capture the details of the road at night, no less than the professional driving recorder equipment. In addition, Xiaomi Mijia smart rearview mirror supports voice wake-up emergency capture and automatic saving of emergency collision video, which will not be erased due to cyclic saving.

The following two pictures are the comparison between Xiaomi's rearview mirror and the professional driving recorder I used before. (Video image screenshot)

▲ The driving recorder I used before.

It can be seen that in the extreme darkness, Xiaomi Mi's smart rearview mirror is like a "night vision device", and you can vaguely see the outline of the object in front, while my previous driving recorder has been blackened and almost nothing can be seen.

▲ The driving recorder I used before.

From the details, Xiaomi Mijia's smart rearview mirror can clearly see the ground lines, and the picture definition is very high. The driving recorders I used before were basically fuzzy.

Generally speaking, Xiaomi Mijia's intelligent rearview mirror integrated driving recorder can completely replace the professional driving recorder I used before.

ADAS Senior Driver Assistant: Experience the sense of technology of high-profile vehicles

ADAS Advanced Driver Assistant is a slightly black technology function. When this function is turned on, the interface is as shown in the above figure. It can accurately draw a lane auxiliary line on the screen according to the real lane ahead, and mark all the vehicles around you. The measured sensitivity is very high. When our speed exceeds 80km/h (it can be set manually, and it is recommended to set it above 80km/h) and deviates from the runway, we will also give a reminder when the vehicle is too close to other vehicles and the green light has not been started for a long time.

This kind of driver assistance function is usually only equipped on high-profile models. This time, with Xiaomi Mijia smart rearview mirror, we can also experience the technological sense of a high-profile model.

Xiao Ai, the co-pilot who grew up with me.

Because of the special environment in the car, we can't control the rearview mirror when driving, so it is particularly important to have an intelligent voice control system with high recognition rate.

Xiaomi Mijia's smart rearview mirror is equipped with "Little Love Classmate" intelligent voice interaction system, and it is also optimized for the interior environment, that is, shortcut command words that can be used globally can trigger operations such as closing the screen, increasing the volume, taking photos and shooting videos. (In order to avoid misoperation, shortcut command words only support fixed command vocabulary).

▲ After connecting with the mobile phone via Bluetooth, you can make/receive calls directly through voice control.

Xiao Ai also supports off-line identification for special situations in the car (no network), such as the instructions of the control system (adjusting volume, brightness, opening applications, etc.). ), as well as some application functions that can be performed offline (such as dialing phone numbers and contacts; Switch the song playing mode, etc. ) can be realized.

▲ Built-in APP Cool My Music, you can order songs on demand.

▲ Built-in APP Himalayan FM, you can order tracks on demand.

For example, some operations that require semantic recognition and networking, such as clicking a song, I want to go somewhere or I need to shout "Little Love Classmate"+networking environment.

Generally speaking, with the blessing of Xiao Ai, Xiaomi's rearview mirror has become very smart. We only need one or two sentences to achieve the operation we want, and with the firmware update in the future, Xiao Ai is like a co-pilot, growing up with me.

Xiaomi Smart Home Interconnection: You can know the situation at home in the car.

Xiaomi Mijia rearview mirror also has a particularly eye-catching function, that is, after adding Xiaomi Mijia smart rearview mirror to Mijia App, when we are in the car, we can turn on and off Mijia smart devices at home through voice commands (such as turning on the living room air conditioner, turning off the air purifier, sweeping the floor robot, etc.), and the control logic of drinking Xiaomi AI speakers is the same.

▲ mijia APP

There is only one Mijia desk lamp at home. Don't use this function without your family knowing ... It's scary.

It is understood that the family early warning function will be introduced in the future. For example, when people enter the home, they will automatically give an alarm in the rearview mirror.

Summary:

Xiaomi Mijia's smart rearview mirror really feels great after experiencing it. The old equipment in my car can be completely replaced by it. It is almost comparable to the current mobile phone in function and much more professional than the mobile phone in vehicle use (after all, few people use the mobile phone as a rearview mirror and a driving recorder).

It is understood that this product will be officially launched at 0: 00 am on April 3, and will be listed in Xiaomi Mall, Mijia Youpin, Xiaomi Home, Tmall Mall and JD.COM Mall at a price of 999 yuan. It is strongly recommended that all car owners buy one.
