Car camera owners often face the need to quickly retrieve video footage after a traffic incident. Xiaomi's modern devices offer several ways to transfer data, but not all users are aware of the nuances of working with the Wi-Fi module and the Mi Home app. Understanding these processes saves time and avoids losing important evidence.
The main challenge is the stability of the connection between the smartphone and the registrar. Data protocols can conflict with the security settings of the Android and iOS operating systems. In this article, we will discuss in detail how to properly organize the local network between gadgets for instant download of files.
There is a direct method through the memory card and the wireless option, and the specific method depends on the situation: whether you need to show the recording to the inspector urgently or you plan to edit a video for social networks. The speed of transmission over Wi-Fi is limited to 2-4 MB / s, so it is better to use a card reader to upload hourly recordings.
Connection via the Mi Home app
The most common way to control the camera is to use official software. First, you will need to install the Mi Home app from the official Google Play store or the App Store. After registering for an account, you need to add the device to the list of available gadgets.
The synchronization process requires care, and make sure that the recorder is Wi-Fi on and the smartphone has GPS activated, and the app will find the camera itself if it is in pairing mode.
- 📱 Launch the app and press «+» top-right.
- 📡 Select your region (important for proper server operation).
- 🔌 Wait for the icon of the DVR to appear in the list of devices.
- 🎥 Click on the device to go to the viewing interface.
The interface of the program may vary depending on the firmware version. In some cases, you need to manually enter the password from the registrar's Wi-Fi network, which is indicated on the case sticker.
It is worth noting that all functions require a stable Internet channel on the smartphone at the time of initial setup, and once the device is linked to the account, video archive management becomes available at any time.
Set up Wi-Fi connection and file transfer
To download a video, you need to switch the smartphone to a network that the DVR itself distributes, 70mai_Dash_Pro. The default password is often equal 12345678, If you have not changed it in the settings.
⚠️ Note: When connected to a Wi-Fi camera, the phone may warn you that there is no Internet access. You must agree to continue working on this network, otherwise the data transmission will be blocked by the system.
Once the connection is successful, the app will open the Album or Gallery tab, which displays all the videos that you have taken, divided into regular events and files saved during the emergency recording (G-sensor), and you can watch the video in real time or start downloading it to your phone's memory.
The boot process can be interrupted when leaving the range of the signal or when switching the smartphone screen to sleep.
- 📂 Select the desired file or tick a few rollers with ticks.
- ⬇️ Click the Download button in the lower corner of the screen.
- ⏳ Wait until the process is complete (the progress indicator will show 100%).
- 📁 The file will be saved in the phone gallery in the folder 70mai or MiHome.
It is better to stop the current recording before mass uploading the archive.

Use of third-party applications
The official software doesn’t always work correctly on all smartphone models, and users turn to alternative solutions in these cases. The 70mai series is a great fit for the 70mai app, which often runs more stable than the universal Mi Home.
Third-party programs may offer advanced functionality, such as a more convenient file manager or streaming capability on a PC, but be careful when granting permissions to access the file system.
For third-party software connection, the procedure is similar to the official one: connecting to the camera's Wi-Fi network, entering a password and logging into the application.
| Annex | Compatibility | Features | Stability |
|---|---|---|---|
| Mi Home | All models. | Integration into the ecosystem | Tall. |
| 70mai | 70mai series | Specialized interface | Very high. |
| 70mai Dash Cam | Old models | Basic functionality | Medium |
| File Manager | Any (via FTP) | Direct access to files | Depends on the network. |
Some enthusiasts use this FTP-clients to access the file system of the registrar directly. IP-device addresses and the presence of root rights or special settings in the engineer's hidden menu.
💡
If the app doesn’t see the camera, try “forgetting” the Wi-Fi network of the recorder in the phone settings and connecting again by entering the password manually.
Direct extraction via memory card
The most reliable and quickest way to get a video file is to physically extract the drive. You'll need a microSD memory card and a card reader that connects to your computer or smartphone via OTG.
Before you extract the card, be sure to turn off the DVR. Hot connection and disconnection of the drive can damage the file system and lose the last records.
Once the card is connected to the PC, a Explorer window will open. Video files are usually located in the root directory or in the Movie/Normal folder. Files have the.mp4 extension and are broken into segments of 1 or 3 minutes.
- 💾 Remove the memory card from the registrar slot.
- 💻 Insert the card into the card reader and connect to the computer.
- 📂 Find a folder with video recordings (usually Movie).
- 📤 Copy the necessary files to the hard disk.
This method guarantees maximum copy speed, limited only by the capabilities of your memory card and USB-It's perfect for backing up a lot of data.
⚠️ Attention: Regularly check the status of the memory card. Flash memory has a limited resource of rewriting cycles.

Solving Connection Problems
Users often experience a situation where the phone sees the registrar's Wi-Fi network but does not connect to it. IP-Addresses or security settings for Android.
In modern versions of Android (10 and above), the system can block data transmission through Wi-Fi cameras, if not on mobile Internet. Try temporarily disabling mobile data transmission in network settings.
Also helps reset network settings on the recorder itself. To do this, in the device menu, find the option “Wi-Fi settings” and select “Reset Wi-Fi” or press the quick menu button on the case before the beep.
If the problem persists, check if the memory card is full. If there is no free space, new files are not written, and the management interface may not work properly.
💡
Connection stability depends on the battery charge of the recorder and the ambient temperature. In the cold Wi-Fi module can work unstable.
Features of working with files and formatting
Xiaomi DVRs use the FAT32 or exFAT file system. If you format a card on your computer, make sure you choose the right file system type, otherwise the camera will refuse to record video.
The best way to format is by the device itself, and there's a "Format SD Card" option in the settings menu, which ensures that you create the right folder structure for cycling.
The G-sensor files are protected from overwriting. If there are too many of these files, the memory card will fill up and the recording will stop. Clean this partition regularly through the application.
Codecs may be required to watch video on a PC if the standard player does not open the file. It is recommended to use VLC Player, which supports most compression formats.
