Xiaomi video recorders (including sub-brands) 70Mai MiVUEs have long been popular because of their combination of affordable pricing, high-quality photography and smart features, but even the most advanced devices require the right setup to unlock their potential. It is not enough to simply insert a memory card and attach the recorder to the windshield - the quality of the video, the reliability of recording in emergency situations and even the battery life depends on the correct parameters.
In this article, we’ll look at all the stages of setup, from basic training to hidden features that aren’t written in the official instructions, how to optimize the recorder for your needs, whether it’s daily city trips, long-distance travel or extreme driving. And we’ll also reveal unique features of Xiaomi firmware that allow you to, for example, automatically save video when braking or integrate with a smart home through the Mi Home.
The material is relevant for all modern models (2020-2026), including Xiaomi. 70Mai Pro+, MiVUE J79, 70Mai Omni and others. If you have an older version, check the compatibility of features in the specifications of the device.
Preparation of the registrar for first inclusion
Before you start setting up, make sure the device is ready to go, a stage that is often missed, but critical for stable operation.
What to do before turning on:
- 🔋 Charge the battery to 100% (even if you plan to connect the recorder to the lighter) This is necessary to calibrate the battery and check its condition.
- 📁 Format the memory card in FAT32 or exFAT (depending on the model). Use the official formatter SD Association or built-in registrar function.
- 🔧 Check the mount: clean the area on the windshield with alcohol, so that the adhesive base is held firmly. GPS-antennae (e.g, 70Mai Pro) avoid installation near metal elements.
- 📶 Update your firmware through the Mi Home app or official website.Outdated software can cause recording failures.
Pay special attention to the memory card. Xiaomi registrars are sensitive to the speed of writing: for Full HD (1080p) Class 10 is fine, or UHS-I (U1), for 4K need UHS-I (U3) Using slow cards results in frames being missed or recordings being automatically disabled.
⚠️ Note: Do not use memory cards larger than 256 GB if your model does not officially support them, 70Mai Midrive D06 It only works with cards up to 128GB, and trying to insert 512GB will lead to a formatting error.
Basic settings through the Registrar menu
After you first turn on, you'll be asked to select the language, date format, and other basic settings, but the real setting starts on the main menu, and to get there, press and hold the Menu button (or touch-sensitive gear icon) for 2-3 seconds.
Key parameters that need to be configured immediately:
- 🎥 Video resolution: Choose from 2560×1440 (2.5K) or 1920×1080 (Full HD) Balance the quality and size of files. 4K Justified for professional photography only.
- 🔄 Cyclical recording: Set the segment length of 3 minutes – this is optimal for video recovery after an accident.
- 📡 Wi-Fi and GPS: turn on GPS-Logger, if you want to link coordinates to video (good for insurance cases). Wi-Fi activate only if you need to connect to the phone - it quickly puts the battery down.
- 🔊 Recording sound: Turn off the microphone (Audio: Off) if you don’t need to record conversations in the cabin (this reduces file size and saves charge).
Note the G-Sensor setting. The default sensitivity is medium, but for urban settings, High is better, which will help save video for even minor collisions, but too high sensitivity can lead to false positives in pits.
| Parameter | Recommended value | Explanation |
|---|---|---|
| Video resolution | 2560×1440 (2.5K) | Optimal balance of detail and file size. 4K card U3 and fills up the memory quickly. |
| Bitreit | Super Fine or Fine | Super Fine is the best quality, but the files weigh 30 to 40 percent more, and you'll need Fine for your daily ride. |
| Cyclical record | 3 minutes | Short segments are easier to recover after crashes. 1-minute snippets create too many files. |
| G-Sensor | High (for the city) | Low sensitivity can miss an accident, high - save video on each bump. |
| Parking Mode (Parking Mode) | On (hard wire) | It only works when you connect to the car's battery via a special cable, and in parking mode, the recording is turned on when you're driving next to the car. |
☑️ Checking basic settings
Configure with the Mi Home mobile app
Appendix Mi Home (or) 70Mai for the corresponding models) opens access to advanced functions that are not available through the logger menu:
- Download the app from Google Play or the App Store.
- Turn on Wi-Fi on the registrar (Wi-Fi button or menu).
- Connect to the Registrar Network (type name) 70Mai_XXXX) phone-on.
- In the app, click Add Device → Video recorder and follow the instructions.
You can use Mi Home to:
- 📲 Watch video in real time (with a delay of 1-2 seconds).
- ⚙️ Update the firmware without using a computer.
- 📊 Configure notifications about the operation of the G-sensor or movements near the car (in parking mode).
- 🔄 Export video to your phone or to the Mi Cloud (free of charge 5GB).
One of the most useful benefits of the app is the ability to set up automatic video saving in case of an accident.
- Go to the Device Settings → Security.
- Enable the Emergency Record option.
- Set the sensitivity of the response (high recommended).
- Activate the option to upload to the cloud if you want backups.
⚠️ Attention: The Mi Cloud’s cloud-based video storage function only works when the recorder is connected to the Internet via a smartphone (Access Point Mode), which quickly consumes up to 1 GB of traffic per hour of recording in Full. HD.
💡
If the registrar is not connected to the app, try resetting your Wi-Fi settings: press the Wi-Fi button for 10 seconds until you hear the beep.
Extended functions: what can be configured additionally
Beyond the basics, Xiaomi’s registrars hide a few useful features that many don’t know about.
1. Mode. ADAS (driver)
Available in models 70Mai Pro+, MiVUE J79 And newer. Includes warnings about:
- 🚗 Get off the lane (unless you have switched on the turntable).
- 🚘 Too close to the car in front of you.
- 🚦 Speeding (if there is data on road restrictions in the database).
To activate ADAS, Go to Settings. → Security → ADAS Note that this feature only works during the day and can give false positives in bad weather conditions.
Voice control
Registrars 70Mai Omni and MiVUE J60 They support voice commands in Chinese and English:
- Go to Settings. → Voice.
- Select the language (English for international firmware).
- Tell me "OK, Mi" and then a command, such as "Take a photo" or "Start recording".
3. Night mode (WDR)
To improve shooting in the dark, activate WDR (Wide Dynamic Range) in video settings, which automatically balances exposure by making car numbers and road signs visible in low light. WDR It can cause noise in video when driving at high speed.
How to update the firmware manually?
Parking Mode (Parking Mode)
Parking Mode allows the recorder to continue recording when the car is parked, useful for fixing vandals, car accidents in the parking lot, or just suspicious activity near the car, but it requires the right connection and setup to work properly.
What you need to do with Parking Mode:
- 🔌 Hard connection to the battery via a special cable (combined with some models or purchased separately). The usual connection to the lighter is not suitable - it turns off when the ignition is turned off.
- ⚡ Battery voltage not lower 11.8V. When the discharge is below this threshold, the recorder will automatically shut down so as not to land the battery completely.
- ⏱️ Record timer: You can only configure continuous recording or activation when you are driving near the machine (saves charge).
To set up Parking Mode:
- Connect the recorder to the battery through a hard wire (red - to the battery). +12V, black-to-mass).
- In the Registrar menu go to Settings → Parking arrangements.
- Select the type of operation: Continuous recording - video is always written (the battery discharges quickly); on motion - recording is turned on when the image is vibrating or changing (optimally); on impact - only when the G-sensor is triggered.
12.0V
⚠️ Warning: If you connect to the battery incorrectly (for example, without a fuse), there is a risk of short circuit.
💡
For models with Mi Home support, you can configure Parking Mode notifications on your phone. To do this, turn on the option of push notifications in the device settings.
Optimizing recording and saving space on the map
Even with a 128GB memory card, the space ends quickly if you don't optimize the settings.
1. Customization of bitrate
Bitrate determines how much data is recorded per second on video. The higher the bitrate, the better the quality, but the faster the card is filled.
- 📹 Full HD (1080p): 15-20 Mbps (enough for a ~8 hours of recording for 64 GB).
- 🎞️ 2.5K (1440p): 25-30 Mbps (~5 hours at 64GB).
- 📺 4K: 40-50 Mbps (~3 hours at 64GB).
2. Automatically delete old files
Turn on Autodelete in the cyclic recording settings. The registrar will erase the oldest files when the map space runs out, but this does not apply to files protected by the G-sensor, they must be manually deleted.
3. Disabling unnecessary functions
Each additional feature increases the load on the processor and the amount of data that is written, and if you don't need it, turn it off.
- 🎤 Recording of sound (Audio: Off).
- 📡 GPS-logger (if you do not keep track of routes).
- 🚦 ADAS (If you are annoyed by false positives).
| Function | Expenditure of space | Recommendation |
|---|---|---|
| Sound recording | +10–15% | Turn it off if you don't have to. |
| GPS-logger | +5% | Include only for long-distance travel |
| ADAS | +20–30% (due to additional video processing) | Disconnect if you do not travel on unfamiliar routes |
| WDR (night-time) | +25% | Only turn on during the dark hours of the day. |
