Modern car DVRs from the Xiaomi 70mai series are complex electronic devices that require the correct initial configuration for stable operation. Many users make the mistake of relying only on automatic default settings, which often leads to failures in recording cyclic video or incorrect operation of the G-sensor. Competent settings begin before the first inclusion in the on-board network of the car and require careful study of the capabilities of the mobile interface.
In this article, we will discuss in detail how you connect your device to your smartphone, calibrate your viewing angle, and adjust your recording parameters for different driving scenarios. The algorithm will be the same for most models in the range, whether it is a compact A200 or an advanced A800S with a screen. It is important to understand that the software part is responsible for the safety of critical data in the event of a traffic accident.
Before starting the procedure, make sure that the memory card is formatted in the FAT32 or exFAT file system, as this is a mandatory requirement for the correct operation of the cyclic record. Incorrect preparation of the media can lead to constant errors and stop recording at the most inopportune moment. Next, we will move to the step-by-step instructions that will help avoid common problems.
Preparation for the first launch and installation of software
The first step is to install a specialized application. 70mai, available in the App Store and Google Play Stores, and third-party use is not recommended. APK-files are from unverified sources, as they may contain malicious code or may not have relevant drivers for your registrar model. After installation, you need to register an account using email or phone number, which will allow you to synchronize settings and receive notifications.
It is important to give the application all the permissions requested, especially access to geolocation and Bluetooth, without which the initial synchronization of the device is impossible. During the registration process, the system can request confirmation via SMS or mail, which is a standard security procedure, only after successful authorization will the full functionality of the gadget management open.
Make sure your smartphone is Bluetooth enabled and geolocated, as these are the channels that are the primary pairing. Some models, such as the 70mai Dash Cam Pro Plus+ A500S, require the phone to turn on GPS to initially calibrate the satellite module, even if the device itself has its own receiver, which is necessary to accurately set the time and coordinates before driving.
⚠️ Note: When registering an account, choose the region “Russia” or “Global”, as the choice of the region “China” can limit the functionality of the server and the speed of the application for users from the CIS.
Once you log in, the app will suggest adding a new device, at which point you click the add button and select your registrar's model from the list. If the model is not automatically determined, you can search by name or QR-code that is usually on the package or the device itself.
Connection of the Registrar and Smartphone
Connecting the device to the phone is done via a Wi-Fi network created by the DVR itself, so plug the device into the vehicle's on-board network and wait for a voice message to say you're ready to go. On your smartphone, go to Wi-Fi settings and find a network with a name starting on the 70mai_, Then enter the default password (usually this one). 12345678).
Once you've successfully connected to Wi-Fi, go back to 70mai, where the Connect or Connect button should appear, and then you exchange encryption keys and set up a secure link, and if the connection breaks down, try restarting the recorder by turning off and reconnecting the power, or forgetting the Wi-Fi network in your phone settings.
- 📱 Make sure that the mobile Internet is disabled on the smartphone (4G/5G) during the pairing so that the system does not try to search for a network on the global Internet.
- 🔋 Check the battery level of the car, as at low voltage Wi-Fi module can work unstable.
- 📶 Keep your phone at a distance of no more. 1-2 meters from the recorder during initial setup for better signal.
It is worth noting that modern models support the connection of multiple users, but priority is always given to the first connected device. If you plan to use a registrar with phones of different family members, make sure that the application is installed on all devices, but settings are better done from the main smartphone of the owner.
⚠️ Note: While connecting to the Wi-Fi recorder, the Internet on the phone will not work, so navigation maps or online music may stop functioning before switching back to the mobile network.
Basic setting of recording parameters
After successful pairing, you need to go to the camera settings section to optimize the quality of the video stream. By default, the device can be configured to standard resolution, but for maximum detail of license plates, it is recommended to set the maximum available value, for example, 1920×1080 or 2304×1296 for the Pro series models. Higher resolution takes up more space on the memory card, but gives a significant gain in the readability of parts.
The critical parameter is the duration of one video, the optimal value is considered to be an interval of 1 or 3 minutes. Set too long interval (for example, 5 minutes) increases the risk of file loss when power failure, and too short (1 minute) creates an excess number of files, which makes it difficult to find the right moment in the archive. HDR (High Dynamic Range, if available in your model, to improve your image in contrast lighting.
☑️ Checklist of basic settings
Be sure to check your audio recording settings. In some situations, such as talking to passengers or talking on speakerphone, you may need to quickly turn off the microphone. In the 70mai app, this feature can be configured as automatic or manual. In addition, activating voice control allows you to give commands like “Take a photo” or “Switch off the screen” without being distracted from the road.
The angle of view is also worth adjusting. Although the lens is physically fixed, the software corrects the edges of the frame (the fish-eye effect). You can choose Full, Wide or Normal mode from the settings menu, depending on how wide you want to grab the side of the road.
Sensor configuration and security system
The effectiveness of the DVR depends on the correct setting of the G-sensor (impact sensor). This component is responsible for protecting the current video file from overwriting in the event of a sharp braking or collision. In the 70mai application, sensitivity adjustments are available: High, Medium and Low. In urban conditions with uneven asphalt, it is recommended to install Medium or Low to avoid false positives on pits and “ly lying police officers”.
The Time-lapse feature allows you to record while parking, recording actions around the car at intervals of 1 second, which saves space on the memory card and allows you to monitor the car for a long time. This feature requires an additional installation of Hardkit (constant power cable), which connects directly to the battery or fuse unit.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Sensitivity of the G-sensor | Medium/Low | Prevents memory overflow with protected files |
| Parking regime | On (from Hardkit) | Control of the car in the parking lot, consumes the charge of the battery |
| WDR / HDR | Included. | Improves visibility in twilight and in oncoming light |
| Sound recording | By choice. | Records conversations in the cabin and sounds outside |
Also in the safety section, you should activate the Front Vehicle Start Reminder, which will beep if the car in front of you is moving and you are getting stuck, and this is especially true for traffic jams and traffic lights, helping to avoid ridiculous collisions and horns in the rear.
💡
If the G sensor is triggered too often on a bad road, try changing the angle of the recorder itself or switching the sensitivity to Low in the application settings.
Working with GPS and additional modules
Many models 70mai Support external connection GPS-module or have a built-in receiver. GPS Not only can you capture coordinates and speed on video, but you can also synchronize time with satellites, which eliminates the need for manual clock settings. You can enable the display of speed and route over the video stream when you view the video stream.
For models with support for ADAS (Advanced Driver Assistance Systems), smart assistants can be configured. The system can warn about lane exit (LDWS) and about approaching the forward transport (FCWS). It is important to understand that these are only auxiliary tools, and their sensitivity must be selected individually so that constant snooping signals do not irritate the driver.
In the case of GPS-Tracking data about the route is stored in the metadata of the file.
