Why do I need to synchronize the registrar with the phone?
Xiaomi DVRs (including the MiJia, 70mai and Xiaomi Auto models) are capable of not only recording video to a memory card, but also transmitting it in real time to a smartphone, which opens up a lot of possibilities, from remote viewing of the recording to instantaneous saving of important moments to the cloud, but many users face difficulties when they first connect β the device does not find the network, the application gives an error, or the connection is constantly broken.
In this article, we will look at all the stages of connection, from hardware preparation to solving typical problems, and pay special attention to setting up the registrarβs Wi-Fi network, since this is where 80% of errors occur, and learn how the process differs for different models (for example, Xiaomi MiJia 1S vs 70mai Pro Plus+) and what hidden functions become available after synchronization.
If you've tried to connect before but failed, don't rush to reset your settings. At the end of the article, there's a section with common bugs and ways to fix them, including firmware issues, app version incompatibility, and Android/iOS limitations.
What Xiaomi models support Wi-Fi connectivity
Not all Xiaomi registrars can stream video to a phone, and here is the current list of Wi-Fi-enabled models (2026):
- πΉ Xiaomi MiJia 1S (including modifications to GPS)
- πΉ Xiaomi 70mai Dash Cam 1S/Pro/Pro Plus+/Omni
- πΉ Xiaomi Auto Smart Dash Cam 2 (with support) ADAS)
- πΉ Xiaomi Mi Car Cam (post-2021 versions only)
- πΉ Xiaomi Redmi Dash Cam (Series for the budget segment)
Models without Wi-Fi (for example, Xiaomi MiJia Mini or older versions of 70mai Lite) can not be connected to the phone β they transmit data only through a cable or memory card. You can check the presence of a Wi-Fi module in the characteristics of the device or by marking on the case (look for the words Wi-Fi 2.4G or 802.11b/g/n).
Also note regional restrictions: some devices (such as the 70mai for the Chinese market) may require special versions of apps or firmware. If you bought a registrar abroad, check it for compatibility with the Mi Home or 70mai App in your region.
What you need to connect
Before setting up, prepare:
- π± Smartphone on Android 8.0+ or iOS 12+ (Older versions of the OS may not support applications)
- π Xiaomi DVR with a charged battery (minimum 50%)
- πΆ Stable Internet connection on your phone (for downloading apps and updates)
- πΎ MicroSD Memory Card (Class Recommended) U3 or V30 videotape 4K)
Also make sure that the registrar has the latest firmware installed.Outdated software often causes connection failures. You can check the firmware's relevance in the device menu (Settings β About device β Software version) or through the official application.
βοΈ Preparation for connection
Important! Some models (like the 70mai Omni) require dual-band Wi-Fi (2.4 GHz + 5 GHz). If your phone doesn't support 5 GHz, the connection may not work. Check the smartphone's specs in the network settings.
Step-by-step: Connection via Mi Home
Most Xiaomi registrars use the Mi Home app to sync.

Connect via 70mai App (for 70mai models)
The 70mai series loggers use their own app, 70mai, and the interface and connection logic are slightly different.
- Download 70mai from Google Play or App Store.

β οΈ Warning: After resetting, all registrar settings (including date/time and recording settings) will return to factory settings.
Additional features after connection
Synchronization with the phone gives access to functions that are not available in offline mode:
- π€ Automatic upload to the cloud: if you detect an accident or a sharp braking, the video is immediately saved on Xiaomi servers (available in the video). 70mai App).
- π Voice Alerts: The app can voice warnings ADAS (For example, "Consist the distance!").
- π Tracking of the route: if the registrar GPS, in the application will display a map with the path traveled and event marks.
- π¬ Video editing: in Mi Home you can automatically create timelapses from trips.
- π Remote control: Enable/disable recordings, change resolution and other settings without physical access to the device.
For models with two-way connectivity (such as the 70mai Omni), once connected, the speaker function will be available, which allows passengers to talk through the registrar (useful for taxi drivers or car sharing).
If you use a parking registrar, set up in the app:
- Parking mode (recording when Detecting movement).
- Notifications about impacts (the app will send a push if someone hit the car).
- Geozone (automatic on/off recording when entering/out of the zone).
