The 70mai brand is Xiaomi’s line of smart gadgets that includes DVRs, car cameras, radar detectors and road safety accessories. Despite the simplicity of the interface, many users are faced with questions about how to properly install, configure or sync the device with the phone. This article will help you understand all the nuances from the first setup to solving typical problems.
We're going to look at not only the basics, but also the hidden features that the manufacturer doesn't always advertise, like how to use voice control in 70mai Pro recorders or set up automatic collision recording (G-sensor), and also how to fix it without contacting the service.
If you’ve just bought a 70mai device or have been using it for a long time but want to reach 100% of its potential, this guide is for you. All instructions are tested on current models (2023-2026) and adapted to the latest versions of the 70mai App.
1. First connection and setup of 70mai device
Before first using the 70mai device, you need to activate and link to the mobile app, which is the same process for most models (for example, the 70mai Dash Cam 1S, Pro Plus+ or Omni), but there are nuances depending on the type of gadget.
Start by installing the official 70mai App (available for Android and iOS) and after you register your account (via Google, Apple ID or phone number), follow these steps:
- 🔌 Turn the device on by connecting it to a power source (in the car, via a lighter or USB- port). Wait for a voice greeting or light indication.
- 📶 Activate Wi-Fi on your device: this usually happens automatically, but on some models you need to press the Wi-Fi button (see the instructions for your camera).
- 📱 In the app, click Add Device → select the type of gadget (like DVR) → follow the on-screen prompts.
- 🔗 Connect your phone to the device's Wi-Fi network (network name starts with 70mai_XXXX). The default password is 12345678 (if it doesn't work, see the sticker on the case).
Once synchronized successfully, the app will prompt you to update your firmware. Don't ignore this notification, the new software fixes errors and adds new features. The update takes 5-10 minutes, so don't turn off the device at this point.
💡
If the camera is not connected to Wi-Fi, try resetting the network settings: press the Wi-Fi button for 10 seconds before the beep.
2.Management through the 70mai App: Basic Features
The 70mai App is your device's control center, and you can not only view the recordings, but you can also adjust the settings of the shooting, turn on voice commands or adjust the radar alerts.
- 🎥 Real-time video viewing: available when connecting to a device's Wi-Fi, with a signal delay of about 1-2 seconds.
- 📁 Record management: Download, delete, protect important files from overwriting (Lock function).
- ⚙️ Camera settings: resolution (up to 2K/30fps or 1080p/60fps), cyclic recording, G-sensor sensitivity.
- 🗣️ Voice commands (for supported models): for example, "70mai, take a picture" or "70mai, turn on the recording."
Pay special attention to the Security section. You can configure:
- 🚨 Accident alerts: The device automatically saves video when braking or impacting (sensitivity is adjusted).
- 📡 Radar Warnings: The camera and stationary radar database is updated automatically (available in models with GPS, e.g., 70mai Dash Cam Pro+).
If you use a 70mai Omni (circular camera), an additional 360° View section will appear in the app, where you can switch between the front and rear cameras or turn on parking mode (recording when driving near the car).
3. DVR setup: resolution, recording cycle and G-sensor
The right settings are critical to the quality of the video and the reliability of the critical recording, and let's look at the key parameters.
| Parameter | Recommended value | Explanation |
|---|---|---|
| Permission | 1920×1080 (Full HD) 30fps | The optimal balance between quality and file size. For the 70mai Pro+, you can choose 2K, but the files will weigh more. |
| Cyclical record | 3 minutes. | Files are broken up into segments. When you fill out a memory card, old records are overwritten. |
| Sensitivity of the G-sensor | Medium | In high sensitivity, the camera will save video even in small shocks (for example, from pits), which will fill the memory. |
| WDR (Extended Dynamic Range) | On. | It helps to avoid overlights and shadows in the frame (especially useful when shooting against the sun). |
To save space on your memory card, enable video compression (if available in your model), which will reduce file size by 20-30% without noticeable loss of quality, and we recommend using memory cards of UHS-I class (U3) or higher – they are optimized for continuous recording.
Set resolution 1080p/30fps| Enable WDR| Set G-sensor to medium sensitivity | Select recording cycle 3 minutes | Activate video compression (if any)
-->
Important: If you use the recorder at night, turn off the Night Mode function manually, the automatic algorithm can degrade the quality of low-light shooting. Instead, increase the value of the Exposure by hand.
4. Cloud connectivity and remote access
70mai devices support cloud storage, which allows you to view records from any device and protect data when the recorder is stolen or broken.
- Open the 70mai App → and go to the Cloud.
- Choose a plan (there is a free trial period of 7 days).
- Activate Automatic Boot for Important Events (Accidents, Radars)
The free rate provides 1 GB of storage, which is enough for ~10-15 minutes of video in Full HD. Paid rates (from 99 ₽/month) offer up to 30 GB and advanced features, for example:
- 🔍 Map search: View records tied to GPS- coordinates.
- 📲 Remote notifications: alerts about the operation of the G-sensor or radar directly to the phone.
If the cloud is not connected, check:
- 🌐 Internet connection stability (the device must be connected to Wi-Fi or mobile network via hotspot).
- ⏳ Sync time: Uploading video to the cloud can take a few minutes.

5. Solving common problems
Even reliable devices sometimes fail, and here are the typical problems and ways to solve them:
⚠️ Warning: If the recorder 70mai is not turned on, check the power supply.Using poor-quality chargers (especially those with an output current <1A) may cause the camera to overheat or fail.
| Problem. | Possible cause | Decision |
|---|---|---|
| The camera doesn't record video. | Memory card not formatted or damaged | Format the card through the registrar menu (Settings → Format). Use microSD cards of class 10 up to 128 GB. |
| The application does not connect to the device | Disparity of firmware versions | Update the camera software and the 70mai App to the latest versions. |
| Video interrupts or lags | Overheating of the device or lack of power | Check the connection to the lighter. When parking in direct sunlight, use a sun visor. |
| Voice commands are down. | The microphone or low volume level is turned off | Turn on the microphone in the settings (Settings → Sound → Microphone) and say the command clearly, with pause after the word "70mai". |
If the 70mai device is constantly rebooting, this may indicate a battery failure (in models with built-in battery) or power problems. Try connecting the camera to another source (for example, powerbank) for diagnostics.
💡
Before contacting the service center, always reset to factory settings (Settings → Reset).
6. Hidden functions and life hacks
The manufacturer doesn't always talk about all the features of the device.
- 🎬 Timelapse: Some models (e.g., 70mai Dash Cam Pro+) can enable accelerated shooting (Settings → Shooting Mode → Timelapse) useful for recording long trips.
- 🔊 Turn off recording sound: If you are annoyed by cabin noise, turn off the microphone in settings (Settings → Sound → Sound recording).
- 📡 Use as a webcam: connect the recorder to a PC via USB and select PC Camera mode (not working on all models).
- 🔋 Charge savings: In Parking Mode, the device goes into sleep mode and is activated only when driving near the car.
For owners of 70mai Omni there is an additional life hack: if you connect an external battery (for example, Xiaomi Power Bank), the camera can work up to 8-10 hours autonomously, which is useful for shooting long-term events (for example, traveling in nature).
Another little-known feature is manually adjusting white balance. If the automatic mode distorts colors (for example, in cloudy weather), go to Settings → Camera → White Balance and select the value manually (for example, Daylight or Cloudy).
7. Firmware Update: Why It Matters and How to Do It Right
Regular firmware updates fix bugs, improve stability, and add new features, such as the latest 70mai Pro+ releases that feature support for road sign recognition and improved night shooting.
You can update the software in two ways:
- Through the app: Connect your device to Wi-Fi. Open the 70mai App → Select your camera → Settings → Software Update. If a new version is available, click Update and wait until it is completed (don’t turn off the device!).
- Manually via microSD (if automatic updates don’t work): Download the firmware from the official website (select your model). Unpack the archive and copy the firmware.bin file to the root of the memory card. Insert the card into the device and restart it. The update will start automatically.
⚠️ Warning: If the 70mai device is powered down during a firmware update, it may cause the bootloader to break, which would require a flashing through USB-OTG at the service center. Always use a stable power source!
After the update, check the performance of key functions:
- 📹 Record video (turn on and off camera)
- 📶 Connect to Wi-Fi and application.
- 🗣️ Voice commands (if supported)
8 Accessories and compatibility with other devices
The 70mai ecosystem includes not only registrars, but also additional accessories that extend the functionality of:
