Xiaomi DVR 70mai Dash Cam Review

Automatic video recording on the Xiaomi 70mai DVR

A distinctive feature of the Xiaomi 70mai dash cam midrive d01 dash cam is the presence of a security function, which is performed by the touch sensor G. When movement is detected near the car, the video camera immediately begins to write in its sector of visibility.

Defog function

If the weather is bad with poor visibility, the video will still be of high quality. This function with the built-in image enhancement program starts to work if the recording is in snowfall, fog, or if light is directed into the lens.

Device memory

The 70mai recorder from Xiaomi works with memory cards up to 64 GB, for which a special slotted connector (slot) is provided. The USB connector is used to charge the device using a Mi Powerbank (portable battery) or a car cigarette lighter, serving as a power source.

High quality video recording on the Xiaomi 70mai dash DVR

The Xiaomi 70mai dash DVR captures images with a resolution of 2592 x 1944 with the WDR function enabled using a 5 megapixel camera with f / 1.8 aperture with a built-in Sony IMX335 sensor. Images are crisp and clear with excellent picture detail. The lens of the DVR covers the situation at 140 °, thanks to which the road is fixed in two directions with the numbers of oncoming cars, and those in front, as well as objects on the sides.

Shooting angle 140 °

The device has built-in GPS navigation system, Wi-Fi router and ADAS driver assistance system. The lens of the Xiaomi 70mai dash cam video recorder is wide-angle, its view is 140 °, covering what is happening in its lane and neighboring.

Voice control

The camera can be controlled by voice by speaking commands aloud. This is extremely convenient as the driver does not have to distract from the road while driving to switch modes.

Video recorder Xiaomi 70mai dash cam. Full overview

The Xiaomi 70mai DVR is a progressive type of such devices, equipped with a 2-inch LCD screen and a 5-megapixel video camera that records with a resolution of 2592 x 1944 pixels. When the car is parked, the camera automatically enters sleep mode, but does not stop monitoring the situation. Thanks to the built-in G-sensor, the device begins to register an extraordinary situation on video, for example, a collision that falls into the field of view. Such captured frames are saved in special files and cannot be deleted.

Parking guard

Your car in the parking lot is always safe when there are no people in it. The Timelapse-enabled dash cam will start capturing the scene automatically if someone approaches it. With a device endowed with such a function, you can leave your vehicle in unguarded parking lots and not worry about its safety.

Advanced functionality

An additional GPS module can be installed in a special connector, which makes available an advanced ADAS (driver assistance) system, which notifies of blind spots, emergency situations, fast approaching objects. With another optional GPSGPRS module, the recorder can be controlled and monitored from a distance. GPS and GPSGPRS purchased separately.

Management, software

The recorder is controlled by five mechanical buttons. The main one. The widest one located at the bottom. Is responsible for the forced switching on and off of the recorder. During the operation of the recorder, the same button turns on and off the display. The other four buttons, lined up in a row, turn off and turn on the sound recording from the microphone, set the flag of an important video, go to the file browser and to the service menu.

Xiaomi DVR 70mai Dash Cam Review

The DVR settings menu consists of several sections, navigation through the menu is performed using the same buttons.

The second control method is voice. The recorder understands four commands: Take picture, Record video, Turn on screen and Turn off screen. Yes, that’s right, in English. The recognition accuracy is quite high, the recorder listens to commands pronounced loudly, quietly, against the background of noise and music, in a male, female or child’s voice. Even the pronunciation of a person who does not know English at all did not prevent recognition. He studied German. At school. 60 years ago.

The third management method is related to mobile devices. The proprietary 70mai application is responsible for this. Before using the application, you need to register with the 70mai service (by the way, why?). The registration process consists in receiving a secret code to the specified e-mail and entering it into the form.

Establishing a connection between the registrar and a smartphone is not difficult, since it is standard: the Wi-Fi point is activated in the recorder menu (it is a pity that there is no separate button for this, as in action cameras), then this point is selected in the smartphone, a standard password is entered (12345678). And the devices are ready to communicate.

The interface of the mobile application is neatly translated into Russian. Application functions are standard and will be clear to anyone.

Selecting the connected device

Choice of frame size, H.264

What is the advantage of connecting wirelessly to car dashboards? Undoubtedly, in the ability to quickly view and copy recorded videos. No need to remove the memory card from the recorder, no need for a computer with a card reader. Well, watching videos on a large display of a smartphone or tablet is incomparably more convenient than on a miniature recorder screen.

The disadvantage of a bundle of a mobile application is that the program, for some reason, does not remember the device once connected. And the connection process, which consists of choosing a device, must be repeated each time.

This is how, almost positively, the chapter on settings and software could end. But these were seeds in comparison with what was ahead of us. It’s about the same GPS / Glonass site.

It turned out that it was not enough to connect two devices, the site and the recorder. The resulting symBIOSis of gadgets also needs to be calibrated. This is not easy. Not only because the user manual, as well as other possible sources, completely lacks any information on this topic.

In recent years, equipment manufacturers have en masse refuse to provide their products with intelligible documentation. What is now attached to small household appliances cannot be called instructions, much less manuals (1. Take the device out of the package. 2. Turn on the device. 3. Follow the instructions). In other words: Have you bought a gadget? Sort it out as you want. Search the forums, collect rumors, go with your own mind. Oh yes. You can also search for information on YouTube.

Our case repeats this offensive trend. All the necessary information is “protected” in the registrar, but you can find out about their existence only by turning on the ADAS function (Advanced Driver Assistance Systems) in the settings. But here’s the catch: the information is presented on the display of the recorder in the smallest text in English. These white letters are displayed at the top of the display, they cannot be seen if there is a light sky in the frame (it, suddenly, is also on top).

The calibration process is performed in the form of a step-by-step wizard, at each stage the recorder issues a portion of the text:

Move the dash cam to align car head with the highlighted area (move the camera to align the center of the car hood with the highlighted area). This means that you will have to tear off the recorder, which was glued to the edge of the windshield, and re-glue it as close to the center as possible so that the camera looks straight ahead and not to the side).
2. Turn the lens to ensure the distant horizon within the highlighted area (rotate the lens so that the horizon is in the highlighted area). That is, you just need to turn the camera unit down or up so that the horizon line coincides with the highlighted area of ​​the screen.

After these conditions are met, the calibration will begin, which is accompanied by a horizontal line moving across the screen, resembling a scanner beam.

In this case, a woman’s voice gives the driver a command in English: Calibration has begun. Please keep your speed at 20 kilometers per hour or higher. Excuse me, we’re in the parking lot. What to do, we will cancel the calibration operation and repeat it somewhere on the most unoccupied track (it is strictly forbidden to be distracted from the road by operations with the recorder).

[after a while] No, it doesn’t work. Calibration starts but does not end; the line continues to scan something. And after 8 minutes, the recorder in a woman’s voice says a sad “Calibration failed”.

What’s the matter? We’ll have to figure it out (oh, how clear instructions are lacking!). What does the recorder do during the so-called calibration? After all, it does not compare the readings of the GPS receiver with the current speed, no GPS device needs such a calibration. No, there is something else related to optical image recognition. It’s not in vain that the scanner strip walks across the screen. And this other is probably somewhere in the ADAS settings.

  • Car ahead move, the beginning of the movement of the vehicle in front (FVSA)
  • Lane deviation (80 km / h), crossing the lane mark while driving at a speed of more than 80 km / h (LDWS)
  • Hit car ahead alert (FCWS)

It is now clear what calibration gives. She trains the recorder, letting him “understand” where the horizon and the edges of the strip are in the frame. With the help of this knowledge and the GPS-platform, the device will warn the driver about an obstacle ahead of the course and about the danger of leaving the lane at a speed above 80 km / h. After plunging into additional ADAS settings, we discovered another recorder ability. A kind of “scene marking”. It is claimed that after turning it on, the recorder “will mark vehicles and lines within the recognition range.” Sounds incomprehensible, but tempting.

The difficulty is that the calibration process, as indicated in the ADAS setup help section, can take 5-8 minutes. All this time, the driver must drive the car at a speed of at least 20 km / h. This means that in a city with its traffic jams and traffic lights, this is impossible. Over. After examining the points that describe the probable reasons for unsuccessful calibration (especially the 4th point, Lane markings are fuzzy and cannot be recognized), it became clear that not only the city, but also most of the roads are missing. Although they are freshly repaired in some places (asphalt is usually laid during the rainy season, before winter), there are no markings on them. Choosing a fine day and driving along the surrounding roads, we nevertheless found an asphalt area suitable for calibrating the recorder. Along the way, we found out the following.

Two conditions are required for a successful calibration. First: a few minutes of driving on the road at a speed of at least 20 km / h, rare stops are allowed. The second condition, the most important, is that there must be clearly distinguishable road markings on the left and right. It doesn’t matter if they are broken lines or solid ones. The main requirement is their distinguishability and presence on both sides of the strip. In our area, the marking on the left (central) is almost everywhere, even if not in a new state. But the markings on the right could only be found on a relatively new section of the road, the sides of which had not yet had time to be covered with a cultural layer of dust and dirt.

Literally after a minute of driving along such a lane, the registrar in a female voice announced the coveted Calibration succeeded.

Let’s rejoice? This is not the time. The ADAS help section contains a little more: after a successful calibration, you need to recalibrate.

I really want to ask the developers of the recorder and the GPS site: why? Why do you need this exciting quest? Why do other car recorders, taken “out of the box”, without any calibration, quite successfully cope with these commonplace standard functions, warning of a possible departure from the lane or about approaching an obstacle?

That was good news (no). Now the news is bad (yeah) The module, which took a lot of time and gasoline to calibrate, turned out to be unnecessary. It does almost nothing. GPS tags, speed and acceleration are not shown on the display or in the video. There is SIMply no data in the video files that could be extracted by third-party programs. The registrar does not warn about leaving the lane (although this is not surprising with our “lanes”). The recorder also does not signal a possible collision. The operation of the module can sometimes be detected only when in a traffic jam: an English-speaking woman hidden in the recorder issues a warning that the car in front has started moving. Well, at least thanks for that, now you can read a book in a traffic jam, and not look into someone’s stern. True, this function does not always work. It requires daylight hours, good visibility and the absence of backlight (the sun should not shine into the lens).

Mount and connect

The set with the recorder has a plastic mounting plate, but we will use another platform, with built-in GPS and Glonass receivers.

To glue the recorder to the windshield anyhow and wherever it is risky business. But you will understand this much later, when you try to set up a joint operation of the recorder with a GPS site. In any case, it should be glued as high as possible and as close to the center of the windshield as possible. Unfortunately, the honorable central place under the mirror has long been occupied by the “regular” registrar, which was installed in the car service. I had to move the review hero a little to the left. Well, above, of course. Here’s what we got.

It looks like the windshield of our car has too much tilt for this recorder: the display of the device “looks” down, instead of being directed at the driver’s face. Either the design of the recorder was tested on off-road vehicles with a small slope of glass, or it was calculated on a driver of small stature. Anyway, all the same, this display is too tiny to be distracted by.

To notice the presence of the recorder in the car from the outside, you need to take a good look. It is easy to assess the possibility of its detection in the photo in comparison with the “standard” recorder, which proudly buLGes out with its lens and dimensions. If this degree of secrecy does not suit the owner, the registrar can be easily removed from the site and put into his .

But here a serious design flaw should be noted. In theory (this is really a good idea), the pad glued to the glass on which the recorder is put on should have a power input. Isn’t it logical? What else are contacts in the site, if not for transferring to the power recorder? In our case, it turns out that, although the mount is quick-release, the removal process itself must be accompanied by pulling out the USB cable from the side connector of the recorder. What will remain of the connector and its contacts after a hundred or two of such disconnections and connections, made, as a rule, in a hurry and often in the dark? That’s right, the USB port will fall apart, the contacts will get worn out. And from an aesthetic point of view, this solution does not look very good. The area on the glass left without a recorder is nothing. But the cable with the connector sticking out from the ceiling looks sloppy.


A SIMilar design and, in general, the concept is not difficult to find among the recorders of other manufacturers. An irregularly shaped body with a protruding rotary camera block is one of the optimal solutions for placement on the windshield.

In the photo, you can see five contacts in the mounting area. Yes, they are specifically designed to work together with a GPS gadget, which also acts as a mounting pad. There are exactly five receiving contacts in its center. Apparently, two contacts provide power to the GPS and Glonass sensors, and the other three transmit information from them to the recorder.

Due to the absence of additional attachments with a long arm, the recorder is glued very close to the glass. This eliminates vibration and therefore jitter in video recording.

If, due to the tilt of the windshield, the recorder camera lifts up or down, taking pictures of the sky or the dashboard, it’s not scary: a remote camera unit, a gray cylinder with an LED strip, can rotate 90 °.

The front panel of the instrument contains an LCD display and a row of four buttons for frequently used operations. Below is another button, the main.

On the right side of the case there is a Micro-USB port for power supply, and just below. A slot for a microSD / SDHC memory card.

On the left side you can see the microphone hole and the external rotating camera block.

The branded cigarette lighter adapter works from 12- and 24-volt on-board systems and is equipped with two USB ports of different capacities. The recorder can be connected to any of them, and the second free port is useful for powering other equipment.

The length of the cable attached to the recorder is 3.5 meters, which is more than enough to lay the wire according to the “invisible” scheme in any car.

Video recording

The codec used to compress the video stream is very sensitive to movement in the frame. So, in videos where there is almost no movement or there are no details, the video bitrate drops significantly from the average values. But as soon as the movement appears, the bitrate level rises to the maximum. This bitrate saving is extremely useful for video surveillance, as it saves space on the memory card. And this behavior is fundamentally different from the work of codecs built into ordinary video cameras or action cameras, where there is no task to save space on the memory card and where the average bit rate is maintained at the same level regardless of the nature of the picture.

The recorder saves video files in a standard MP4 container during recording. The number of frame size options depends on the selected codec.

In addition to this main video recorder, the recorder SIMultaneously saves the same clips, but with a smaller frame size, 640 × 360. At the same time, the frequency remains the same as in full-size video, 30 frames per second, and the bit rate reaches 2 Mbps. These files are used for playback on a smartphone when viewed in direct mode.

As you can see, the frame rate in all modes is exactly the same, 30 frames per second. In the settings of the registrar there is no item for selecting the frame rate. There is only a point where the frequency of the region’s power supply is set (50 or 60 Hz).

The resolution of the video generated by the recorder camera reaches 1600-1700 TV lines on the horizontal side of the frame in the older shooting mode (2592 × 1944). A more accurate determination of the resolution is hindered by pronounced aliasing (stepped contrast boundaries). Along with a decrease in the frame size, the resolution also decreases, but it falls unevenly, but in a sinusoidal manner. So, in Full HD mode, the resolution is already 900-1000 TV lines.

Proceeding even from this synthetic testing, we can draw the following conclusion: for the permanent operation of the recorder, it makes sense to use the largest frame size. Only it gives details comparable to full-fledged camcorders and cameras that shoot in 4K. Yes, this mode requires more space on the memory card, but you hardly need to worry about saving. Unlike stationary video surveillance, mobile does not need to store records for weeks or months. As a rule, an important video fact has just been captured, this very minute (an accident or other event). If you don’t waste time, you can copy the required incident record without fear that this video will be overwritten by new records.

True, this maximum frame size (2592 × 1944) gives a non-standard aspect ratio, 4: 3. Due to the large viewing angle (140 ° diagonal) with such recording, the camera almost completely captures the dashboard, which is completely unnecessary in the recording.

The registrar imprints the 70mai logo, as well as the current date and time into the video frame. These values ​​must be set manually in the device settings, remembering to keep track of their relevance (any quartz watch is always a little behind or in a hurry).

Due to the high resolution of the DVR camera, with good illumination in the video, you can see every little detail. License plates become distinguishable at a great distance, and the direction of movement of the observed car is not important: due to the good sensitivity of the sensor, the camera sets a short shutter speed. And as you know, the shorter the shutter speed, the clearer the frame.

Automation controls the exposure of the frame well. So, even with oncoming bright light (headlights, sun), contrasting details along the course of movement remain intact, do not light up.

The original video of this ride against the sun can be downloaded from this link (163 MB).

But, we repeat, this quality is possible only with a sufficient level of illumination and low speeds.

Exactly the same will happen at dusk, and even more so at night. In such conditions, do not even dream of getting any distinguishable outlines of fast-moving objects.

Talking about the quality of shooting, we will give our traditional freeze frames taken from day and night shooting from the same angle in motion. With their help, it is easy to understand what is the difference between day and night shooting.

We must admit: compared to most of the inexpensive car recorders available on our market, this device records exceptionally well. Such a high quality of shooting is present, perhaps, only in top branded devices and in no less branded action cameras.

An important addition: during the recording, the recorder divides the material into segments of one minute, as all recorders do with the “circular” recording mode. It is noteworthy that there are absolutely no gaps at the junction of two video files that are formed by our recorder. The owner does not have to worry that some kind of incident will happen at the moment of the junction of two files: the recorder records everything that he sees.

Power, heating

When the power is supplied, the recorder turns on automatically, video recording starts already two seconds after the recorder is turned on. When the power is turned off, the DVR will finalize the current video file and turn off. The recorder can be turned on forcibly even when the power is off, in which case it will continue recording until the energy reserve in the built-in battery runs out. This reserve is enough for 55 minutes of autonomous recording in H.265 Full HD mode. In the parking mode with the motion detector turned on, the recorder could last much longer on the battery. However, the battery life in the parking monitoring mode is for some reason limited by software. The available maximum is 50 minutes, after which the recorder will turn off.

During a long video recording, the body of the device heats up slightly. Below are thermal images of the device taken after several hours of continuous video recording with the display on. Tested in room conditions with an ambient temperature of approximately 24 ° C.

It can be seen that the case heats up the most in the area of ​​metal contacts for communication with the GPS pad, here the temperature reaches 45 ° C. This temperature poses no danger to the electronics. True, there is a risk of additional heating of the case by the sun’s rays in the summer. But cooling will help here, because on hot days the driver probably turns on the air conditioner, blowing cold air onto the windshield.

Review of 70mai Smart Dash Cam Pro car DVR with display and camera rotary unit

Additional functions

The recorder as a separate independent gadget is just a camera that can imprint the current date and time into the frame. The registrar has no other functions, except for the possibility of connecting with a smartphone. And it could have the ability to warn about leaving the lane, or to imprint coordinates, speed and other data into the frame. Could. If the developer had brought to mind this described GPS site, with whose calibration we pretty much suffered. Precisely, the connection of the site with the registrar.

Perhaps the additional functions that work smoothly include the built-in G-sensor with a three-stage sensitivity setting, as well as a parking recording mode with a motion sensor. By the way, we immediately switched the G-sensor to the low sensitivity mode, because at the middle level, the emergency recording is activated on every bump.

The sound in the video recording of the DVR is recorded in AAC with a bit rate of 128 Kbps. The built-in microphone does not “mumble” or “hiss”. Every sound in the car, including the soft speech of the driver and passengers, is clearly recorded and clearly distinguishable in the recording. There is no booming or cutoff characteristic of cheap microphones.

Specifications and scope of delivery

The registrar is packed in an almost cubic black box with a laconic print. From the information printed here (model name, 70mai.com website and the smallest text on the sticker) it is impossible to understand what this is all about in your hands. Together with the recorder, we received another useful (no) accessory called 70mai GPS Mount Holder. Unfortunately, there is virtually no information about this device on the “native” site. However, the purpose of the accessory is easy to understand from its name. It is a mounting pad with a built-in GPS receiver (Glonass support is also announced).

There is nothing in the package with the GPS site, except for the site itself and empty microscopic instructions. However, there is also a transparent sticker of an incomprehensible purpose, on which, if you look through a microscope into the light, a gluing diagram is drawn and something is written on the topic of electrostatics.

The complete set of the registrar looks richer:

  • Video recorder 70mai Smart Dash Cam Pro
  • Cigarette lighter power adapter with 3.5 m cable
  • Adhesive pad
  • Quick start guide (too short and too small)
  • Two transparent stickers (electrostatic sticker), one of the same is included in the set with the GPS pad
  • Flat plastic part with curved tip

By the way, about the last detail. Thanks to the phenomenal brevity of the user’s manual, the function of this bow is not easy to grasp. Options such as a digging stick for a pet mole or a table hockey stick. They, of course, please the soul, but they are not like the truth. Only those who have ever laid cables inside a car on their own can understand that with this stick the cable is safely tucked under the interior trim.

Information about the features of the registrar was put on the side edge of the box.

A modest but recognizable manufacturer’s logo.

The box is made of thick cardboard and is able to protect the recorder on the way to the buyer. The black foam insert serves the same purpose.

The recorder is packed into a paper bumper, on the bottom of which there was a drawing-instructions for laying the cable in the car. How many registrars have come across, and I see recommendations on this for the first time, thought out to the smallest detail.

The rest of the accessories are stacked in the lower tier of the box.

Together with the instructions in the package, there were two electrostatic stickers, through which the recorder is attached to the car glass. One sticker spare.

I first met this type of DVR mount on the Xiaomi 70MAI model. At first I was skeptical, but my doubts were dispelled by the year of operation of this recorder. There was not a single case of peeling off the sticker and falling of the recorder. The mount is reliable.

It looks like a SIMple transparent film, but it holds tenaciously on the car glass, and a registrar tripod is already glued to the outlined circle in the center.
I was very pleased with the instructions for this registrar. Since the version is global, the instructions contained sections in English, Chinese, Spanish and unexpectedly Russian, for which many thanks. Over, this is not a Google translation, not an anecdotal puzzle, but a really normal Russian language.

The rest of the accessories in the kit, except for the bracket and a spare mug of double-sided tape for gluing the tripod to the electrostatic sticker, are packed in separate bags.

One of the packages contained a rare thing for recorder kits. A spatula for laying the power cord under the rubber seal and car interior trim elements.

Familiar already to me from Xiaomi 70MAI single-port charging at 5 Volt 2.4 Ampere.

A tripod for installing a recorder with a rotary mechanism is very small, it will not be conspicuous and look foreign in the car. A spare round of double-sided tape in case something goes wrong.

And the last accessory is a 3.5 meter power cord for the recorder with a L-shaped microUSB plug.

The updated version of the registrar, just like the previous one, also looks neat and is designed in an attractive style of Xiaomi minimalism.

A drawing with instructions for installing the recorder was applied to the protective film of the display. It’s SIMple and it’s hard to make a mistake.

On the top of the case there is an on / off button, a bracket lock and a power connector for the recorder. In the same photo, you can see that the lens barrel is made of metal and has a knurl.

On the underside of the recorder there are holes for the reset button and microphone, as well as a sticker with brief characteristics.

The operating mode indicator and the memory card slot are located on the left side of the case. The slot is closed with a cover and accidental loss of a card or clogging of the slot is practically excluded.
The indicator glows white during shooting. In the event of an emergency, the indication color changes to red.

The right side of the case does not contain any functional elements.

For order and an idea of ​​the overall dimensions, the measurement results.

When assembled with a bracket, the camera is still very compact and does not take up much space on the glass. Swivel mechanism allows you to adjust the desired angles.

Turning on the recorder is accompanied by a melody, and when you turn it on for the first time, the user is immediately prompted to choose one of four interface languages ​​- English, Russian, Chinese or Spanish. Not a very large selection, but still quite global.

After choosing the language, the recorder interface will guide the user through the instructions and presets.

Further and always after connecting the power supply, the recorder will turn on and record. If there is no memory card in the recorder, then he will ask you to insert it, if it is inserted and everything is in order with it, then the indicator on the side will glow white.

All control of the recorder is carried out by four touch buttons marked with white dots under the screen. The screen itself is not touch-sensitive and touching the icons above the buttons will not give results.

The DVR status bar is located at the top of the screen. During recording, a red dot blinks next to the Rec label, the date and time are projected, as well as the crossed out Wi-Fi icon if the registrar is not connected to the Mi Home application on the phone. The P symbol also appears here when the parking monitoring function is activated. Parking monitor.
By default, video recording is silent and the microphone icon is crossed out. By touching the touch button, turn on the microphone, and the video will already be with sound.

The checkbox button activates the process of recording emergency video from a separate folder on the memory card (maximum 20% of the total), you can erase this video only through a computer or when the folder is full and the recorder starts to delete the oldest recordings.
The user can erase a regular video at any time, or it will happen when the memory is full, and the recorder will also begin to replace the old video with new files.
Files weigh 237 MB each, containing 2 minutes of video.
Gallery icon button moves user to DVR memory folders.

Going to any folder stops video recording, which is indicated by the corresponding inscription on the screen. After returning from any folder to the gallery, video recording resumes.
Files inside folders are represented by large icons.

The last touch button activates the DVR settings menu, where you can turn on / off the sound when the DVR is turned on, set the time to turn off the screen after starting recording, etc. Etc…

You can set the sensitivity of the shock sensor of the recorder or turn it off altogether. Taking into account the condition of the road surface, I chose low sensitivity, otherwise crossing the tram rails or falling into a small hole causes video recording to the emergency folder.

You can select the recording quality (only two options marked as “finished”. 1080p with a resolution of 19201080, i.E. FHD, and the usual 1280 720, i.E. HD) and select the language again.

It is possible to adjust the speaker volume, view the status of the memory card and format it.

The next screen of the settings menu allows you to set the date and time, set the shock sensor sensitivity of the parking monitor function, and start the system update.

Do not forget about the possibility of resetting to factory settings and viewing information about the software.

All of the above operations can be done from the phone by connecting the recorder to the Mi Home application. In addition, the application will become available to take a photo. For some reason, they forgot about such a function in the registrar.

To connect to Mi Home, you need to turn on the access point of the registrar (the very first item in the settings menu).

In Mi Home, the registrar should be found in the “Nearby Devices” tab. When connected, the Wi-Fi settings window opens on the phone, where a new network appears. Midashcam1s_v2_8508. When connecting to this network, you will need to enter the password that was on the recorder’s screen. On subsequent connections, you do not need to enter a password, you just need to select the desired network.

As noted above, the application adds the ability to take photos. You can also watch the video recorded by the registrar by entering the gallery. Video recording stops again.

The settings menu item is indicated by three dots in the upper right corner of the screen, and from here you can perform the same manipulations with the recorder as through its buttons, plus check the software update and change the name of the gadget. A little later, a software update arrived to version 1.0.5

Items related to setting up the recorder from the application completely duplicate the button manipulation option.

When connected to a computer, we can see the folder structure and photo / video.
A normal video is stored in the Normal folder, in the Event folder. A video about how we drove into a pit or an accident happened. Video about events immediately after hitting the car during parking (when the car, for example, stands in the yard at night) is dropped into the Monitor folder.

I would like to draw your attention to the fact that if you activate the surveillance mode during parking, then after it, when you need to go somewhere, this mode must be turned off, since it does not turn off automatically and event video (accident, entering a pit, etc.) will not be saved in the events folder, but will generally be recorded in the folder for normal video, i.E. Will not be protected from erasure.
In parking monitor mode, the recorder is powered by an internal battery. In case of hitting the car, the recorder starts recording without turning on the screen and without attracting attention. When the owner turns on the ignition, the recorder with a voice message and text on the screen informs about the presence of a new video in the Monitor folder.

The angle of view of the recorder was checked by the following method: “We put 2 columns on the floor at a certain distance from each other, for example, 2 meters (the more, the more accurate the measurement result will be). Exactly between them we put the recorder and move it away from the line connecting the posts, watching the picture. As soon as the columns are at the very edges of the frame, we measure the distance from the recorder to the line.
If b is the distance between the posts, and is the distance from the lens to the line connecting the posts, then the angle = 2 arctan (b / 2a) ”
In my case, b turned out to be 6.95 meters, and. 2.2 meters, and the viewing angle of the recorder was 115.34 degrees, which is noticeably better than that of 70Mai. Stated 140 degrees. Most likely diagonally.

There is nothing more to add in terms of functionality and I suggest looking at the quality of shooting.

In daylight, the registrar proved to be quite confident in fixing the situation on the road and car numbers not only in the same lane, but also in the oncoming one. Over, there is no distortion of the picture even in the lower corners of the frame and the numbers of the cars can be read. The change of illuminated and shaded areas is well practiced. There is no glare of the sky, which often happened on the video filmed by the 70Mai recorder.

Since Youtube degrades the video quality, the link to the original.

The DVR sensor quickly adapts to shooting video of poorly lit and well-lit areas.

The lack of WDR function affected only at night. There were times when the license plates on the video were overly illuminated. The main reason for this is the too bright head light of my car. However, in the corners of the frame and in adjacent lanes, where the lighting is not so intense, the license plates are read quite normally.

In all cases, the shooting quality was set to maximum.

The registrar does not take a photo at the level of a DSLR, but it is quite normal for the gadgets of its sector.

The recorder does not take up much space on the glass, without interfering with the view and remaining unobtrusive from the street.

I can only compare this registrar with 70Mai. In terms of the quality of the daytime picture, they are comparable, but the processing of details in the corners of the frame is slightly better with the Xiaomi Mi Dash Cam 1S. The 1S also copes better with transitions from poorly lit to well-lit areas; on a sunny day, there is no unnatural flare of sky areas. The presence of the screen is a definite plus, i.E. The recorder is completely autonomous. Product support is ongoing and software updates are available. A parking monitor is provided and operates normally. Appearance, build quality can not stand for consideration. As usual neat for Xiaomi. Overtemperature protection is provided, which disconnects the recorder from the power supply.
