How to connect Xiaomi Registrar to phone, Wi-Fi and power: full instruction

Xiaomi video recorders (including popular series) 70mai And Mi Cars have become an integral part of a smart car, but their first connection is often questionable, and even experienced users face problems syncing with their phone, setting up Wi-Fi, or running the app incorrectly. This article will help you understand all the nuances – from choosing the right cable to fine-tuning notifications.

We will look at not only standard connection scenarios through the Mi Home app or the 70mai, But also alternative methods for cases where automatic synchronization is not working. 5G Wi-Fi (Pro and Ultra models) that require specific router settings, and if you've tried to connect your device and you've got a "failed to connect to the registrar network" error, here's the solution.

1.Preparation for connection: what to check before starting

Before you start setting up, make sure all components are compatible. About 30 percent of the problems with connecting Xiaomi loggers are due to mismatched firmware versions or inappropriate accessories.

• 📱 Smartphone: Supported OS - Android 8.0+ or iOS 12+. On Android 13 devices+ Additional location access permission may be required (even for Wi-Fi connections).
• 🔌 Power Cable: Use only the original USB-Cheap analogues often don't provide stable voltage. 5V/2A, This leads to spontaneous reboots of the registrar.
• 📶 Wi-Fi module: Registrar 70mai Dash Cam 2/Pro and Mi Car DVR They only work in the range 2.4 GHz. If your phone is connected to 5GHz networks, switch temporarily.
• 🔋 Power source: When connecting to the lighter, check the voltage - it should be within the limits 12-24V. Use of the USB-Laptop hubs can cause an error "Insufficient power supply".

Pay special attention to the memory card. Xiaomi Registrar officially supports microSD class UHS-I (U1/U3) capacity 256 GB, but in practice with SanDisk Ultra or Samsung cards EVO Plus capacity 128 GB and higher have formatting problems. FAT32 cluster-size 32 CB through the program SD Card Formatter.

⚠️ Note: If you use a registrar with a function ADAS (driver's assistant), make sure that the memory card has a write speed of at least 30 MB / s. At a lower speed, the device will miss frames when writing in night mode.

2. Connection of the registrar to power: schemes and nuances

Improper power connection is the main cause of spontaneous shutdowns of the recorder. Let's consider three standard scenarios:

1. Connecting to a lighter is the most reliable option. Use the original adapter. 12V→5V If the recorder turns off when the engine starts, check the voltage of the side network with a multimeter - it should not fall lower. 11.8V.
2. Connection to USB-Port of the car - only works if the port gives current at least 1.5A. Otherwise, the registrar will be rebooted when recording the video in 4K.
3. Hard wiring to the battery - requires the installation of an additional fuse 3A and using relays to turn off the recorder with the ignition, 70mai A800S) connection ACC+.

If the registrar does not turn on when connecting to the cigarette lighter, check:

• 🔌 Polarity of the connector (central contact should be "+").
• 🔋 Condition of the fuse in the adapter (usually) 2A).
• 🔧 The presence of oxidation on the contacts of the cigarette lighter (clean with alcohol).

💡

If the recorder turns off when the engine starts, connect it through a voltage stabilizer (for example, Xiaomi Car Charger Pro).

3. Connect to the phone via Wi-Fi: step-by-step instructions

The logger syncs with the phone through its own Wi-Fi network. The connection algorithm is the same for all models, but there are nuances for devices with dual-band Wi-Fi (for example, for example, the connection algorithm is the same for all models, 70mai Omni, follow the instructions:
