How to set up a 70mai DVR on Android Xiaomi

Integrating the modern 70mai car DVR into the Xiaomi device ecosystem is a process that requires attention to detail but greatly improves the comfort of the car. Android smartphone owners often face aggressive battery optimization that can interrupt connection or block the application from running in the background. The correct initial configuration will avoid losing important records and ensure the stable operation of the Wi-Fi module.

The main challenge is that the MIUI or HyperOS shell has strict power management rules that by default limit third-party software. If you want your 70mai A500S or A800S to work as a full-fledged smart car, you need to manually configure permissions, which ensures that critical event notifications come instantly and that video streams don't stop because of the system's sleep.

In this guide, we will take a detailed look at all the steps of connection, from physical installation to fine-tuning Xiaomi system settings. You will learn how to bypass the limitations of the operating system and make the 70mai application work consistently 24/7. Following these steps will ensure reliable fixation of the traffic situation without having to keep the smartphone screen on all the time.

Primary installation and interconnection of devices

The first step is to physically install the recorder and turn it on first. Make sure the microSD memory card is formatted to the FAT32 or exFAT file system, as this is critical for correctly recording cyclic video. Once power is connected, the device should issue a voice greeting, and the status indicator will flash, signaling readiness for pairing.

Next, download the official 70mai app from Google Play or GetApps (for Xiaomi devices), and when you first start it will ask you to register an account or log in through an existing one, which is a mandatory procedure for activating cloud functions and synchronizing time over the Internet.

⚠️ Note: When registering, select the region that corresponds to your actual location, as this depends on the choice of server and the speed of cloud functions.

To connect, go to the Wi-Fi menu on your Xiaomi smartphone.Look for a network with a name beginning on the 70mai_, and enter the default password, which is usually listed on the sticker under the device or in the instructions (often this is the default password). 12345678). After successful connection, return to the application and press the device add button.

• 📱 Make sure that the Bluetooth and Geolocation settings on your phone include app permissions.
• 🔋 Charge the registrar before setting up so it doesn’t turn off during the firmware update process.
• 📶 Do not connect to the 5 GHz network, registrars 70mai They only work in the 2.4 GHz band.

After successfully adding the device to the list, the app will offer a firmware update, which is highly recommended right away, as newer versions of firmware often contain fixes for Wi-Fi connection stability, which is especially important for Xiaomi smartphones.

Configure MIUI and HyperOS permissions

The most critical step for Xiaomi owners is to set up access rights. MIUI's Android operating system is known for its strict energy saving policy, which by default "kills" background processes, including connecting to the registrar. Without the right configuration, you may not receive a notification of impact or parking.

Go to Settings → Apps → All apps and find 70mai. In the Permissions section, you must give full access to all items, especially Location, Memory and Notifications. Denial of access to geolocation can lead to tracks in the application being built incorrectly.

Pay special attention to the item "Out-Start." In the Xiaomi ecosystem, this is a switch that must be active so that the application can run with the system or when connecting to the registrar's Wi-Fi network. Also in the "Other permissions" section, turn on the display on the locked screen and work in the background.

The important parameter is "Battery and performance." Here you need to select "No restrictions." If you leave the standard value "Energy Saving", the system will periodically break the connection to save charge, making it impossible to view online streaming or receive push notifications.

After making all the changes, restart your smartphone, which will allow Xiaomi to apply the new rules to a particular application and fix them in memory.

Solving problems with Wi-Fi connection

A common problem is when a Xiaomi smartphone sees the registrar’s network, connects to it, but writes “No Internet access” and switches back to mobile traffic. This is because Android tries to check for the Internet through the registrar’s network, does not find it and breaks the connection.

To fix this, you need to change the Wi-Fi settings for the 70mai hotspot. Connect to the logger, then in the phone's Wi-Fi settings, click on the gear or arrow next to the network name. Find "IP Settings" or "Static IP" and make sure it's activated.

Also in advanced Wi-Fi settings (often hidden in the "Additional" menu or require you to enter code in the jingle ##6484## for the engineering menu, but easier through roaming settings), find the option "Switch to mobile Internet" and select "Don't switch" or "Always use this network." This will force the phone to keep a connection to the registrar, even if there is no Internet.

⚠️ Warning: After such changes, remember to manually switch back to your home Wi-Fi or mobile internet when you’re done with the registrar, otherwise you won’t have access to the network.

Another nuance is the frequency of the channels. Some 70mai models can automatically switch Wi-Fi channels when disturbed. If the connection is unstable, try fixing the channel in the settings of the recorder itself (via the app) or changing the channel width to 20 MHz for greater signal range.

If the phone loses communication when moving away from the car, try changing the position of the antenna inside the cabin or using the device. USB-lengthener.

Setting up notification and parking mode

To implement the parking function (Time-lapse or Motion Detection) requires not only the correct configuration of the application, but also the appropriate equipment. GPS-With the module and the additional camera, make sure that the functions of "Parking Control" and "Accumulation Sensor" are activated in the application).

Setting the sensitivity of the G-sensor is important, and too high sensitivity will cause the recorder to block files from overwriting every time a door or truck slams, quickly filling out the memory card, setting an average or low value so that only real collisions are recorded.

Notifications to MIUI may or may not arrive late unless the Important Notifications channel is configured. Go to Settings → Notifications and Status bar → Notification Management → 70mai. Make sure Critical Alerts are on and marked as priority. This will allow the audible alarm to sound even in Do Not Disturb mode.

• 🚗 Enable the "Time-lapse" function to save space on the map when parking.
• 🔔 Configure push notifications only for critical events so as not to spam your phone.
• 💾 Check the Events folder in the app regularly, as files are blocked from being deleted.

It is worth noting that for the parking mode to work 24 hours a day, it is necessary to connect the registrar to the car battery through a special cable (Hardwire Kit), since the standard power from the cigarette lighter with the engine silenced is usually not enough or it is turned off by the car itself.

Working with memory card and file system

Recording quality and stability are directly dependent on the memory card. For 70mai DVRs, it is strongly recommended to use High Endurance cards from manufacturers SanDisk, Samsung or Kioxia. Conventional cards for smartphones quickly fail due to constant cyclical overwriting.

Periodically (once in a 1-2 Format the memory card through the menu of the application itself, which helps prevent file system errors and "broken" sectors. → Memory settings → Format.

If you encounter an error called "SD Card Error" or "No SD Card", try formatting the card on your computer. Use the official SD Memory Card Formatter utility. Select the exFAT file system for cards with 64 GB or higher and FAT32 for cards up to 32 GB.

💡

Using a high-quality High Endurance memory card extends the life of the registrar and ensures the safety of the video at a critical moment.

The app also has a setup for the duration of a single video file (1, 2 or 3 minutes). For ease of viewing and transferring files over Wi-Fi, it is better to choose 1 or 2 minutes, since smaller files are faster to copy and less susceptible to damage when a sudden power failure.

Additional functions and integration

Modern 70mai models like the A800S or A500S support voice control. In Russian, commands can work in limited ways, but basic features like "Pick a photo" or "Block a video" are often recognized. Check the relevance of voice packets in the app settings.

Remote View is also available, which allows you to see the status of the car over the Internet if the recorder is connected to an external battery or a car with constant power, and this feature requires stable mobile Internet on the phone and the correct time on the device.

Remember to check the date and time settings. The best way to do this is to set up Internet time synchronization (NTP) in the registrar settings, which will ensure that the video recordings are timed correctly, which can be a decisive argument in a contentious situation on the road.

Getting the 70mai DVR set up correctly on Xiaomi takes time, but it’s worth it. You get a reliable digital witness who’s always ready to record what’s happening on the road, and following the energy conservation and access rights guidelines will ensure that the system runs smoothly throughout its life.
