Installing and initial setup of Xiaomi’s car DVR often raises questions among new users, especially given the device’s minimalist interface. The main interaction is through the smartphone rather than the screen of the gadget itself, which requires careful pairing. A stable connection is the key to quickly accessing video recordings and managing device settings in real time.
In this article, we will take a detailed look at all the steps of connecting, from selecting an application to solving common signal problems.You will learn how to properly configure Mi Home or a dedicated 70mai client to ensure your registrar works without failure.The right network configuration will allow you to use the device at full capacity, including cloud functions and remote browsing.
Before you start the software part, make sure the hardware is ready to go, a basic but critical step that is often ignored when trying to get the application running right away, and the physical connection must be done in a good way to avoid power problems later on.
Preparation of equipment and selection of applications
The first step is to install the necessary software on your mobile phone. Depending on the DVR model (for example, the 70mai A500S, Xiaomi Mijia 1S or the newer 4K series), you may need either a universal Mi Home app or a dedicated 70mai.
Once the application is installed, you need to register an account. For users from CIS countries, you sometimes need to change the region in the application settings to China or Europe to determine the device correctly. Regional settings play an important role in the availability of servers and the stability of cloud functions.
⚠️ Note: Download apps only from official Google Play or App Stores. APK-Files may contain malicious code or may not work properly with new firmware versions.
Make sure your smartphone has connectivity modules on. Bluetooth and GPS (for iOS) are critical to initial setup, as well as geolocation access. Without location permission, the app may simply not find the device on the list of available devices to connect to.
Here is a list of the main actions before the start:
- 📱 Install the Mi Home app or 70mai smartphone.
- 🔋 Charge your phone to minimum. 20-30% stable operation of the Wi-Fi module.
- 📡 Enable Bluetooth and geolocation in operating system settings.
- 🔌 Connect the DVR to the power source (power bank or on-board network of the car).

If the app doesn’t see the device, try to force a search by pressing the device add button manually rather than relying on automatic scanning.
The process of pairing via Wi-Fi Direct
The main method of communication between the smartphone and the registrar is to create a Wi-Fi Direct hotspot by the DVR itself. Once the device is turned on in its menu (manage buttons on the case), you need to go to the Wi-Fi settings. On the registrar screen or through voice commands (if the model supports), you will see the network name and default password.
Open the Wi-Fi settings on your phone and find a network with a name that contains the device model (e.g., the phone’s Wi-Fi settings, 70mai_DashCam_XXXX). Connect to it by entering a password. By default, passwords are often a sequence of numbers, such as, 12345678, It is better to check this information in the instructions for a specific model.
Once you successfully connect your phone to the registrar network, go back to the app, and it should automatically detect the device and suggest that you add it. If that doesn't happen, press the + button in the corner of the screen and select your model from the list. The synchronization process takes 10 to 30 seconds.
It's important to understand the difference between Wi-Fi modes: When a phone is connected to a registrar, it loses access to the Internet via a mobile network unless you set up an automatic switch. The registrar access point mode is only for local data transfer, it does not provide access to the global network.
Set up network and region parameters
The correct region setting is an often overlooked but vital point: Xiaomi servers are geographically distributed, and if your account is registered in one zone and the device is trying to connect to the servers of another, there may be authorization errors or delays in status display.
In the app, go to the user profile and check the Region setting. Most European models are suitable for Russia or Germany, Chinese versions (CN Version) often require switching to China. Changing the region may require re-authorization in the app.
| Parameter | Recommended value | Note |
|---|---|---|
| Region of the account | Russia / Europe | For official deliveries |
| Wi-Fi frequency | 2.4 GHz | 5 GHz is often not supported |
| Interface language | Russian/English | Depends on the firmware version. |
| Time. | Automatically (GPS) | Synchronization through satellites |
Also worth paying attention to is the frequency of the Wi-Fi signal. Most budget and mid-range Xiaomi models only support the 2.4 GHz band. If your smartphone tries to connect through 5 GHz, the connection may not be established or work unstable. In modern smartphones, this feature is often called “Smart Wi-Fi Switching” and it is better to temporarily disable it when set up.
Why is the registrar not connected to the home Wi-Fi?
Working with a microSD card and formatting
Once you've successfully connected to an app, the first thing you need to do is check the status of your memory card. Xiaomi DVRs are very demanding on the quality and speed of recording microSD cards. Using cheap cards from unknown brands can lead to loss of archives and constant errors in the application.
In the app menu, find the Storage Settings or Status section, which will show the amount of space occupied and the current status of the card. If you insert a new card or card from another device, be sure to format through the application. The file system must be compatible with the registrar's Linux-like OS.
The formatting process is triggered by a button in the application interface, so don't interrupt the process or turn off the power of the device, and when it's done, the recorder will create the folder structure necessary to record the loop.
☑️ Memory card check
Note cycling. You can choose the duration of one video file (1, 3 or 5 minutes) in the settings, and the optimal value is 1 or 3 minutes, since in the event of a power failure or impact, there is less risk of losing the entire recording fragment if the file was damaged during recording.
Update of firmware and advanced settings
Regular software updates are key to a stable device, and manufacturers often release patches that improve video compression algorithms, Wi-Fi connectivity stability, and security bug fixes.
The app usually shows a notification of the new version in the device card. Before starting the upgrade, make sure that the car battery is charged or the engine is running to avoid battery discharge in the process.
The update process looks like this:
- 🔄 Click the “Check Updates” button in the app.
- ⬇️ Download the update package (may take a few minutes).
- ✅ Confirm the installation and wait for the device to restart.
- 🔌 Do not turn off the registrar’s power until the process is complete.
⚠️ Warning: During the update, the indicator on the body may flash red or orange. This is normal. Forced shutdown at this point can lead to the "bricking" of the device.
In advanced settings, it is also recommended to activate the G-sensor function and adjust its sensitivity. Too high sensitivity will lead to fast filling of the card with “protected” files that are not deleted during cyclic recording. Calibration of the G-sensor is especially important after reinstalling the recorder to a new location.
💡
Always complete the firmware update to the end, even if it seems that the process is stalled.
Solving Common Connection Problems
Even if you follow all the instructions, there can be failures. One of the most common problems is that the phone "sees" the registry network, but writes "No Internet access" and breaks the connection. In modern versions of Android and iOS, this is a standard behavior: the system protects the user from connecting to "useless" networks.
To fix this, click on the Wi-Fi network information icon in your phone’s settings and enable the option “Don’t switch to mobile data” or “Connect anyway.” Also, temporary mobile traffic shutdown (LTE/4G) helps during setup time.
Another problem is the slow speed of video transmission, which may be due to overheating of the Wi-Fi module in the recorder, so if the device has been operating for a long time in direct sunlight, its internal temperature may exceed the permissible limits, and the communication chip reduces power or shuts down. Let the device cool down.
List of frequent mistakes and decisions:
- ❌ Device is busy: Close the app completely and run again, check if the phone is connected to another camera.
- ❌ «Wrong Password: Reset your Wi-Fi settings from the registrar’s menu (usually a voice command or long press of a button).
- ❌ App crashes: Clear the app cache or reinstall it, check access rights.
If nothing works, complete a full reset through the hole on the device body using a paper clip, which will return the network settings to factory values.
