How to completely or partially turn off the sound in the DVR Xiaomi: microphone, alerts, system sounds

Xiaomi DVRs are a popular solution for fixing traffic, but their sound is not always appropriate. Loud voice radar alerts, constant microphone noise or system signals can distract from driving or annoy passengers. In this article, we will discuss all possible ways to turn off the sound in the recorders Xiaomi 70Mai, MiVue, Mijia and other models, from completely turning off the microphone to selectively turning off notifications.

It's important to understand that the interface and settings may differ from one model to another, for example, in the Xiaomi 70Mai Pro, the audio menu is in a separate section, and in the MiVue 796, some of the options are hidden in "Additional Settings." We'll look at universal methods and also nuances for specific devices. If your model does not support software-based disabling of sound, there are alternative solutions in the article.

1. Completely shutting down the sound through the settings menu

The most obvious way is to take advantage of the built-in registrar options, and most Xiaomi models allow you to turn off the audio completely or partially through the interface.

• 🔊 Step 1. Turn on the recorder and wait for the main screen to load. Press the Menu button (usually indicated by a three-strip or gear icon).
• 🎵 Step 2. Go to Settings (or Settings in English firmware) in some models, such as: 70Mai Midrive D06, You need to select System settings.
• 🔇 Step 3: Find Sound, Volume, or Alerts:

If your model doesn’t have a separate Mute switch, try setting the volume to a minimum. In some recorders (such as the Xiaomi 70Mai Lite), this is the only way to mute the sound without completely turning off the microphone.

⚠️ Note: In models with firmware until 2022 (for example, MiVue 736) after the software update, menu items may change places.

2.Mic Shutdown: Why It Doesn't Always Work

Many users want to turn off voice recordings in the cabin, not system sounds, but in theory, this can be done through settings, but in practice there are nuances:

• 🎤 Software shutdown: in the menu of some models (e.g, 70Mai Midrive D08) There's a Microphone with an Off option, but once the recorder is restarted, the microphone can be activated again.
• 🔧 Physical shutdown: In budget models like the Mijia Mini, the microphone is often soldered into a board, and you can only turn it off by disassembling the device, but that doesn't guarantee that it's safe.
• 📱 Processing in the application. in the official application Mi Home or 70Mai Sometimes the option of removing the audio track is available when viewing the recordings, but this does not cancel the recording itself.

In Xiaomi recorders with Novatek NT96660 chip (such as the 70Mai Pro), the microphone is controlled by a separate controller. Its software shutdown may not work due to the features of the firmware. If you are critical to remove the sound recording, consider models with a hardware microphone switch (for example, the BlackVue DR900X, but this is not Xiaomi).

3. Selective disabling of notifications

Not everyone needs to turn off the sound completely. Often, just removing voice radar alerts or deflection warnings is enough.

1. Turn off camera alerts: Go to Settings → Security → Radar Alerts. Select Off or On-screen Only (if available).
2. Remove Start/Stop Sound: In System Sounds, turn off Start Sound and Shutdown Sound.

Turn off the button signals:

• Find UI Sounds or Key Tones and set No.

In ADAS (driver assistance) registrars, such as the Xiaomi 70Mai Dash Cam 1S, you can set up alerts for:

• 🚗 Departure from the lane (LDWS)
• 🚘 Too close a distance (FCWS)
• 🛑 Speed disturbance

Make sure the registrar is connected to the power supply.|Make a backup of the settings (if there is a function)|Check the firmware version (relevant for 2023 models)+ year-end)|Record the current sound settings in case of a return-->

4. Resetting settings as a last resort

If the sound doesn't turn off after the changes or the recorder starts to work unstable, resetting to factory settings will help.This will remove all your settings, including POI points and recording settings, so use the method only as a last resort.

Instructions for most Xiaomi models:

1. Go to Settings → System → Reset.
2. Select Reset All Settings or Factory Reset.
3. Confirm the action (it may be necessary to enter) PIN-code, if it is installed).
4. Once you reboot, turn off the audio again via the menu (see Section 1).

⚠️ Note: In registrars Xiaomi based on the chip Ambarella A12 (For example, MiVue 750, it can take up to 2 minutes to reset, and don't turn off power during the process, it will damage the firmware!

If the sound is turned on again after reset, check:

• 🔄 Update the firmware to the latest version (sometimes bugs with sound are fixed in patches).
• 📋 Check if the settings in the Mi Home app are lost (if the registrar is connected to it).

5. Alternative methods: if the menu does not help

What if your model doesn't have a switch-off option or it doesn't work? Here are some non-obvious solutions:

• 🔌 Disable the speaker physically. In some recorders (e.g, 70Mai Midrive D05) The speaker is connected via the connector. Carefully disassemble the body and disconnect the plume.
• 🎧 Connect your headphones. Some models, like the Mijia Smart Dash Cam, support the output of sound to a 3.5mm jack. Put your headphones on and leave them in the jack, and the sound will go there.
• 📱 Record processing. Use programs like Audacity or Adobe Premiere to remove audio tracks from video files.
• 🔇 Put a piece of foam or tape on the microphone (usually next to the lens) and it won't turn it off, but it will significantly mute the surrounding noise.

Important: Physical interference with the device (disassembly, depolding of the speaker) deprives of warranty. If the registrar is warranty, first try software methods or contact Xiaomi for support.

6. Frequent mistakes and how to avoid them

When trying to turn off the sound, users often encounter typical problems, and here are the most common ones and ways to solve them:

If none of these methods helped, check:

• 🔍 Some OEM versions (for example, for taxis) have a lock on audio settings.
• 📦 Cheap Xiaomi-branded clones may lack software support for turning off the sound.

💡

Before selling or transferring the recorder to another person, reset the settings to the factory. In some models (for example, the 70Mai Pro), snippets of sound from the cabin can be stored in memory even if the microphone has been turned off.
