The Xiaomi 70 Mai DVR is one of the most popular solutions for capturing traffic situations thanks to a combination of price, quality and smart features. However, even such a simple device requires the right setup to unlock the full potential, from recording videos correctly to integrating with a mobile application. Many users miss key points — for example, not optimizing the resolution for a memory card or setting up a G-sensor, which causes significant loss of footage in an accident.

In this article, we’ll look at all the steps of setup, from physical editing to hidden firmware features that the manufacturer doesn’t advertise, how to avoid common mistakes (such as why the registrar can spontaneously turn off) and how to set up notifications so that they don’t discharge the phone, and also exclusive life hacks that you won’t find in the standard instructions.

⚠️ Warning: Don't attach the recorder to the torpedo or dashboard! In an accident, it can fly off and injure passengers. Also avoid places where the camera will be heated by the sun - this reduces the battery life.

Lay the power cable so that it does not interfere with the control of the car.

1. From the recorder along the ceiling to the front of the windshield.
2. Down the rack (hidden under the skin, if possible).
3. Under the torpedo to the lighter or fuse (if you connect directly).

💡

Use plastic clips to mount the cable – they are cheaper than special car screeds and will not damage the skin.

2. First Entry and Basic Settings

After installation, connect the recorder to power, and when it first turns on, it will automatically start the setup wizard.
