entranceXiaomi registrar rearview mirror. Review of the Xiaomi Mi Rearview Mirror Recorder MJHSJJLY01BY DVR, which replaces the rearview mirror
We have been following the Xiaomi brand and its latest developments for a long time, among which we would like to highlight the Xiaomi Smart RearView Mirror. It comes with a fairly large 8.88-inch display with a resolution of 1920 × 480, supports 16,700 thousand colors, and consists of seven mirror layers with an optical coating and an even distribution of incoming and outgoing light. Judging by the description, you probably already understand that this is not an ordinary mirror, but a screen that provides many interesting properties, which we will gladly tell you about.
Device characteristics
The M1 model measures 303.8mm x 76mm x 40mm and weighs 393g including clips. It has a quad-core processor with a MediaTek MT8665 chip, clocked at 1.5 GHz. The device also uses a sensor model OmniVision 2718, battery 370 mAh. Its working temperature is not lower than -20 and not higher than +70 degrees.
It should be noted that Smart RearView Mirror has internal memory is equal to 16 GB, there is the possibility of using microSD, but not more than 64 GB, and 2G, 3G, 4G, WiFi, Bluetooth 4.0, BLE & FM are also available.
Smart mirror description
We were satisfied that the device comes in a black case with touch screen and a camera on the back. It doesn't matter what color you install it in the car, the black surface will fit into any interior design.
For us, the Xiaomi Smart RearView Mirror DVR has become an indispensable assistant on the road, thanks to its new flagship intelligent voice interaction, which controls the majority of the device's functions. If you think that this will interfere with the driver's driving, then you are mistaken, since speech can be stopped at any time when necessary.
Additionally, the smart mirror has an integrated map created specifically for the vehicle. She is able to satisfy a large number of requests. So, we made sure that the map easily switches to display mode and changes the trajectory of movement to the destination.
Distinctive feature This model is that it has a built-in ADAS system that supports FCW, PVS and LDW. Once we were driving along the highway, and opposite a steep jeep flew at a breakneck speed. The driver clearly did not calculate his strength and the car simply skidded into the oncoming lane. Our smart mirror immediately let us know about the critical situation on the road, and we were able to avoid the collision. And how many times did it tell us that we crossed a double continuous strip, thereby allowing us to give right in time and not violate traffic rules.
By the way, the system allows you to archive video of an accident before and after the incident. The picture of the event can be played back in the rear-view mirror itself or through the application in the smartphone online.
Thus, thanks to the built-in sensors this model Xiaomi collects information from outside and inside and warns if there is a danger. In turn, the lens High Quality allows you to get ultra-clear pictures. The mirror has an integrated OV 1 / 2.9 image sensor equipped with a high resolution, thanks to which we record very high quality video (080P / 30FPS) even in low light.
Xiaomi smart device has a 4-in-1 mixed cooling system, which provides high thermal protection. The hot air inside the vehicle is passed through copper. Thermal silica gel contributes to an increase in the speed of the process, and to enhance the effect, the developer has provided graphene, which allows you to expand the cooling area.
Specifications
conclusions
For those who miss driving, the smart mirror entertains with listening to good music, audiobooks, top programs, etc. About 20 different categories are available to the driver and his passengers.
But what we liked the most is that the Mi Home system can be connected to the device to control devices at home.
It is worth mentioning that custom software from Android is installed on the smart mirror, which significantly expands the circle useful functions available on this device... We bought Xiaomi Smart RearView Mirror for 10 thousand rubles, but if we are lucky, the device can be bought for 9 thousand. Also, see the review of the minimalist Xiaomi Yi Car WiFi DVR 1080p.
Another test of small arms for survivability during continuous fire was carried out by experts from the Kalashnikov concern. A video report about testing is presented on the popular channel "Weapon Destroyers". Read moreXiaomi is renowned for its innovative designs.

Opening the box, inside you can find:
- main unit of the DVR;
- 2 elastic bands with which it is attached over the standard rear-view mirror;
- cigarette lighter power adapter with one USB port;
- long USB to Micro-USB cable to power the device;
- instructions for Chinese.
The power adapter is the simplest, with one port.
The power cable is quite long - 3.5 meters.
The instruction uses the Latin alphabet and Arabic numerals only in those places where it comes to technical characteristics- Wi-Fi range, Android version, etc. So it is practically useless for a non-Chinese user.
Also included in the delivery set is a certain plastic "tool", which, most likely, is proposed to be used during the installation process. We never figured out how to use it, and we did fine without any tools.
Exploitation
Control
The device is controlled by 5 buttons located under the mirror. Center button has a small protrusion on the surface so that it can be felt without looking.
If the video is playing, that is, the screen is not blank, the actions that they perform are indicated above the buttons. Actions (and indeed the image on the screen) are signed “internationally” - with icons, the meaning of which is, in principle, intuitive.
This is, of course, great, but even if you guess that the rightmost button is the settings menu, then after clicking on it, you will find pure Chinese without any hints of anything else.
Photographing a mirror surface is a thankless task, so we used screenshots from the Mi Home application, with which the DVR can be controlled by connecting to it via Wi-Fi - the hieroglyphs are the same there, but the quality of their image is much better than the screen photo.
However, before you can start controlling the device, you need to somehow connect to it. Insofar as this process not devoid of pitfalls, we will describe the main steps. We used the Android version of Mi Home.
- The first, the most simple task- find Mi Home in Play Market and install this app.
- The first time you start it, you will be asked for the language and location. You can choose any language you like (Russian is present), but the location must be strictly "Mainland China" - otherwise you won't succeed.
- Next, you will need to add the dash cam plugin to Mi Home and connect to it. Point Wi-Fi access will be named "MiRMCam_v1_A854". To find out the password for it, go to the settings menu of the DVR (the rightmost key), find there the item that starts (starts!) With "Wi-Fi". Choose it. Under two hieroglyphs, you will see a sequence of 8 Arabic numbers - this is the password of your point.
- If on the home screen, top line, the Wi-Fi symbol is crossed out - the access point is turned off. Go to the same menu item as described above and press the right key - Wi-Fi will turn on. It turns off the same way, that is, the key simply switches the modes on / off.
Now about the management. The registrar has few settings, so it's not so difficult to understand them, even if everything is in Chinese. Next, we will provide screenshots of the Mi Home application and (hopefully) their correct translation into Russian. Translatable interface elements are placed in a list in an intuitive order: top to bottom, left to right. The settings menu items of the DVR itself (as it seemed to us) for the most part coincide with the Mi Home menu.

As you can see, there are really few settings - we did not find even the most familiar ones here, for example, setting the duration of one "piece" of video. For Xiaomi, it is equal to 2 minutes, and this cannot be changed. In general, the concept of Apple "we know you better" is copied by the "Chinese Apple" directly and consistently;)
All connectors are located on the top of the device.
This is Micro-USB for power, microSD and a small "jack" where the rear camera is apparently connected. There are clear hints of the possibility of connecting a rear camera in the directory structure of the microSD card, so it's safe to say that it really exists - but it was not in our kit.
A ball-and-socket lens protrudes from the left side of the device, facing the windshield.
Fastening
The mount and its principle of operation are standard for this form factor of DVRs and, from our point of view, do not require any additional explanation.
Collaboration with other devices
If you connect the dash cam to a computer using a USB to Micro-USB cable, it simply perceives it as plugging in a power source. So, apparently, the device does not know how to communicate with a computer.
Field trials
The process of installing the DVR on the rear-view glass was not difficult.
One of the not very pleasant moments: if the driver is not tall and is forced to strongly "twist" the rearview mirror towards himself, the possibilities of the lens hinge may not be enough to perfectly align it: as a result, the DVR will look not exactly in the center, but slightly slightly to the right.
The image on the screen when viewed from the side is very poorly visible, and if you also take into account the fact that there are hieroglyphs, dreams of adjusting any parameters while driving should be buried right away. Only through a stop, twisting the mirror towards yourself, etc. Well, or through hot keys. For example, the far left turns on / off the microphone, the middle right takes a photo.
The G-sensor on bumps of a country road worked even at low sensitivity. At the end of the test operation, we turned it off completely.
We did not find any hints of a motion sensor.
The concealment of the installation on one side is quite high ... but only if the eye does not "attack" the lens flare. And this is easily possible - the diameter of the first lens (or protective glass?) - about 13 mm.
Test results
HDR / WDR
We have not come across any hints of support for these functions.
Video
By default, we use a continuous piece of about 2 minutes for test videos, recorded in the maximum resolution supported by the device. If the device uses the MP4 format as a container, no conversion is performed. If MOV is used, it is converted to MP4 without re-encoding. In all other cases, the video sequence is recoded to MP4 with a deliberately high bitrate in order to avoid quality losses.
Bitrate original video in our case it was equal to 15.9 Mbps.
The device supports only one resolution - Full HD 1920 × 1080, so we had no choice.
Now let's watch the night video.
In general, what we see fully corresponds to the wording "an average good car Full HD video recorder on a Sony matrix." Nice picture, good dynamic range and colors, in the night picture there are obvious traces of noise reduction, making it more elegant, but at the same time killing small details. Everything is as always: a solid "four" - Xiaomi did not spoil anything, and we did not expect more from this matrix.
Photo
The photos, judging by the quality, are just screenshots from the video.
Sound
Sound as sound. There is almost no low-frequency "bubnezhka". Details are audible quite clearly, even quiet ones. On one of the video recordings made during the testing process, the conversation between the driver and passengers who drank coffee, standing outside the car in the area of the hood, was quite clearly audible.
conclusions
On the one hand, we can say that Xiaomi MJHSJJLY01BY is a classic version of “install, connect, set up once, and forget”. This format is quite in demand, the demand for it is stable.
On the other hand, you will not be able to completely forget, because this device does not speak either Russian or even English, so any communication with him, even the most fleeting, will be accompanied by certain difficulties. For example, you will have to learn / memorize a few hieroglyphs;)
With the third - you can really "set up and forget", and if necessary, show someone a video of what happened - remove the card from the device, insert it into a laptop or tablet, and then everything is clear without Chinese.
Probably, if one of us decided to take this DVR for ourselves, then he would have chosen the third option. So it is somehow easier.
Separately, it is worth noting the rather long operating time of the device from a fully charged battery - more than an hour. True, it is not very clear how to use this feature: when the power is turned off, the DVR automatically turns off, and we did not find any ways to cancel it.
