Installing a modern car DVR is not just about mounting your device on the windshield, it’s about integrating it fully into your car’s digital ecosystem. 70mai DVRs, a sub-brand of Xiaomi, require initial setup via a smartphone to activate all of the smart features like voice control, ADAS (collision warning system), and GPS time synchronization. Without this step, the device will only work in basic recording mode, negating the benefits of buying an advanced model.
The initial activation process can be confusing for beginners because of the interface language barrier and the way the registrar connects to the access point itself. Many users encounter difficulties during the interface stage, when the phone does not see the device or the Wi-Fi connection is terminated immediately after entering the password. In this article, we will discuss in detail how to connect the 70mai registrar to the phone, consider the nuances of working with the application for different models and eliminate typical errors that occur during the first start.
Preparation of equipment and installation of the application
Before you try to connect devices, you need to make sure that all components are ready to work. The main management tool is the official 70mai app, which is available in the Google Play Market and App Store. It is important not to confuse it with the YI Home or Mi Home app, since ecosystems can vary depending on the year of release of the device and the region of delivery.
Download the app to your smartphone and register an account. You can use a phone number or email to register. You can choose the region in the app settings to automatically or manually set the country corresponding to your location, although this is not a critical feature lock option for most registrar models.
💡
Use the same Xiaomi account (Mi Account) that is already logged in to your smartphone if you use the brand’s devices to make it easier to sync your data.
Make sure the DVR has a microSD card installed. Without a memory card, the device may not turn on completely or will constantly emit sound errors at start. It is recommended to use 16 to 64 GB U3 or V30 cards (for some models up to 128 GB), specifically designed for DVRs, as they are better able to handle cyclic overwriting.
Physical connection and first launch
Once you have the software installed on your phone, you go to the physical mount, connect the power cable to a Mini USB or Type-C connector on the recorder case (depending on the model), and connect the power supply to the USB car port or lighter, the device screen should light up, and the characteristic beep signal to start work.
When you first turn on, the device may ask you to select an interface language. If the menu is in Chinese, focus on the icons: usually it is the second or third line in the settings menu (cog or globe icon). Choose English or Russian if this option is available in your version of the firmware. English is universal for all 70mai models.
☑️ Primary start of the device
After selecting the language on the screen will appear QR-The code and the name of the device's Wi-Fi network, which are signals that the logger is ready to pair. Write down or take a picture of the network name and password if they are displayed, although in most cases the password is standard and is listed in the manual or on the sticker under the device.
The process of pairing through Wi-Fi
The most important step is to create a bridge between your smartphone and the registrar. Open the 70mai app on your phone and press the add-on button (usually the + icon in the upper right corner). The app will request permission to use geolocation and Bluetooth — be sure to confirm these requests, since in Android 10 and later without GPS, you can not find Wi-Fi devices.
In the list of available devices, select your model. If the automatic search does not yield results, select the model manually from the list (for example, 70mai Dash Cam Pro Plus+ A500S Lite 3). Next, the system will ask you to connect to the registrar's Wi-Fi network. Go to your phone's Wi-Fi settings, find the network with the name starting at 70mai_, and enter the password.
⚠️ Attention: When you connect to the Wi-Fi recorder, your smartphone may warn you that the network has no Internet access. This is normal. Don't disconnect from that network, even if the phone insists on switching to mobile traffic.
Go back to 70mai. It automatically detects the connection and prompts you to complete the setup. If that doesn't happen, press the Connect button manually. It takes 10 to 30 seconds. Once you're successfully connected, you'll see a live stream from the camera on your smartphone screen and you'll be able to manage the settings.

Configuring the main parameters in the annex
Once you've successfully connected, you'll go to fine-tuning. In the main menu, click on the settings icon (cogs). Here are the critical settings that affect recording quality and usability. First, check the Video Settings section.
Make sure the resolution is set to the maximum value supported by your model (e.g. 1944P for the A500S or 2160P for the A800S). Also, the cyclic record is configured here. It is recommended to choose an interval of 1 min or 3 min so that in the event of an incident, you do not have to wait long to save the desired fragment.
| Parameter | Recommended value | Description of the impact |
|---|---|---|
| Permission | Maximum (2K/4K) | Clear numbers and details on the road |
| Frequency of personnel | 30 fps | Smooth video, reducing load on the map |
| Impact sensor (G-Sensor) | Medium sensitivity | Protecting files from overwriting in case of accident |
| Parking regime | Off (without additional cable) | Savings in the battery charge of the car |
| ADAS | On (optional) | Warning to exit the lane |
Time Lapse is useful for long trips where you don't have to record every second in high resolution, and in this mode, the recorder takes pictures at regular intervals, saving space on the memory card.
💡
The optimal setting of the G-sensor is “Medium”: with high sensitivity, files will be blocked from shaking on a bad road, quickly filling the memory card.
Solving Typical Connection Problems
Despite the simplicity of the procedure, users often experience technical failures, and the most common problem is that the phone sees the recorder's Wi-Fi network but doesn't connect to it, or writes "Impossible to connect," and 90 percent of the time, it's solved by rebooting both devices: turn off the recorder, turn off the phone's Wi-Fi, and then turn it back on.
Another common error is that the app says "Device is busy" or "Connected to another device." This means that another phone has already been connected to the registrar or the previous session was not correctly completed. Wait 2-3 minutes or complete the full cycle of the recorder power on/off.
- 📱 Problem: The phone doesn't see the registrar's Wi-Fi network.Solution: Check if it's on GPS on a smartphone and whether the application is given permission to geolocate.
- 🔄 Problem: Persistent connection breaks when watching video. Solution: Get closer to the device, the wi-fi signal of the recorder is weak due to the compact antenna.
- 🔋 Problem: The recorder shuts down immediately after the power outage. Solution: The built-in battery is only used to save settings and time; it needs constant power from the car to work.
⚠️ Note: If the registrar stopped creating a Wi-Fi network after a failed upgrade or failure, try resetting to factory settings (Reset) by pressing the reset button with a thin object during the course of the reset. 5-7 seconds with the device on.
For models with GPS-It's important to wait for satellites to come on the first time you're on without the internet, and it can take up to 15 minutes (cold start) to find satellites. GPS.
Update firmware and additional functions
Once connected successfully, the app can suggest updating the firmware. Updating is an important process that fixes bugs, improves the Wi-Fi module and adds new features. Download updates only through the official app when the phone is connected to stable Wi-Fi (home), and not through the access point of the recorder, so as not to interrupt the process.
During the upgrade, the recorder screen will go out and light up, the device can make sounds. It is strictly forbidden to turn off power at this point. Once the update is completed, the device will automatically restart. If you used a third-party memory card, format it through the recorder menu after the update.
Many models, such as the A800S or M500, support voice control, and when connected, you can activate voice commands in English or Russian, and phrases like "I want to take a photo" or "Take a photo" allow you to capture important events on the road without being distracted from driving.
