Does a Dash Cam Record Sound?

Dash cams have become an essential gadget for drivers around the world—offering security, evidence in case of accidents, and even peace of mind during everyday commutes. While most people focus on a dash cam’s video quality and field of view, there’s another important feature that often gets overlooked: sound recording.

Many drivers wonder, “Does my dash cam record audio?” or “Should I even have it turned on?” In this guide, we’ll dive into whether dash cams typically record sound, how you can check if yours does, and how to enable or disable it.

Do Dash Cams Typically Record Audio?

Built-In Microphones Are Common

Most modern dash cams come equipped with built-in microphones. These microphones are typically small and located discreetly on the device’s body, allowing them to capture ambient sound from within the vehicle. Whether it’s a conversation between passengers, the sound of a horn, or verbal exchanges with law enforcement, the microphone is capable of picking up a wide range of in-cabin audio.

Dash cams from leading brands like Garmin, Nextbase, VIOFO, and BlackVue generally include this feature as standard. In fact, many mid-range and even budget models offer audio recording capabilities, making it a common feature rather than a premium one.

Audio Recording as a Default Setting

In many dash cams, sound recording is enabled by default. This means that unless you manually turn it off, your device will likely be recording both video and audio every time it’s active. However, some models give a voice alert or visual indication when audio is being recorded, so you’re not caught off guard.

It’s important to read your dash cam’s manual or explore its settings to verify whether audio recording is active. This is especially useful if you want to avoid recording private conversations or comply with local privacy laws.

Differences Across Brands and Models

Not all dash cams are created equal. While most offer audio recording, the quality can vary significantly. Entry-level models may include low-sensitivity microphones that pick up muffled or distorted audio, especially when there’s road noise or music playing. Premium dash cams, on the other hand, may feature noise-reduction technology and higher-quality microphones for clearer recordings.

Some dual-channel dash cams—those that record from both front and rear cameras—may only include a microphone on the front unit. That means audio will mostly reflect what’s happening in the front cabin area, not in the back seat.

Audio Recording: Optional but Valuable

Although audio recording is not always essential, it adds a valuable layer of context to your footage. In the event of an accident or traffic stop, recorded sound can help clarify what happened, especially if someone is giving verbal instructions, making threats, or admitting fault.

For these reasons, most manufacturers continue to include and improve audio recording features in their devices. If you’re in the market for a new dash cam, make sure to check whether the model you’re considering supports audio—and how easy it is to enable or disable it.

How to Know If Your Dash Cam Records Sound

Check the Product Specifications

The first and most reliable way to find out if your dash cam records sound is by checking its product specifications. Manufacturers usually indicate whether the device includes a built-in microphone in the feature list. Look for terms like “audio recording,” “built-in mic,” or “voice recording” in the product description, on the packaging, or in the user manual. If you bought your dash cam online, revisit the product listing to see if audio features are mentioned.

If you can’t find any reference to sound recording, visit the manufacturer’s website or look up your model number to find detailed specs or downloadable manuals.

Explore the Dash Cam Settings Menu

Most dash cams with audio capabilities include a setting to turn sound recording on or off. This is usually accessible through the device’s menu on the screen interface or through a companion app if the camera has smartphone connectivity. In the settings menu, look for options labeled “Audio,” “Mic,” “Sound Recording,” or similar. Toggle the setting to see if it’s currently active.

Some dash cams display a small microphone icon on the screen while recording—if this icon is visible, it generally means audio is being captured.

Perform a Quick Audio Test

If you’re unsure whether your dash cam is recording sound, a simple test can confirm it. Start a recording, then speak clearly or make a distinct sound (like tapping on the dash) while sitting inside the car. Afterward, stop the recording and play it back either on the dash cam screen or through a computer or smartphone, depending on your model.

Listen carefully during playback. If your voice or the tapping sound is audible, your dash cam is indeed recording audio. If there’s only silence or background noise like the engine, the microphone may be off or the model may lack audio functionality.

Look for Microphone Indicators

Physically inspecting the dash cam can also provide clues. Look for a small pinhole or a mesh-covered area labeled “MIC” on the camera body—this is usually where the microphone is located. If you find this, it’s a good indication that the device can record audio.

Some high-end dash cams even include voice control features, which obviously require a microphone to function. If your model supports voice commands, it almost certainly includes audio recording capability.

Review User Reviews and Forums

If you’re still uncertain, search online for user reviews or forum discussions about your specific model. Other owners often share whether their dash cams include audio recording and how effective it is. This can also help you learn how to enable the feature if it’s buried in a less intuitive settings menu.

How to Enable or Disable Sound Recording

Accessing the Settings Menu

To enable or disable sound recording on your dash cam, start by accessing the device’s settings menu. Most dash cams have a built-in screen with navigational buttons or a touchscreen interface. If your model supports smartphone connectivity, you can also access settings via a mobile app. Once you’re in the menu, look for options labeled “Audio,” “Sound,” “Microphone,” or “Voice Recording.”

In many cases, there’s a simple toggle—either a checkbox or an on/off switch—that controls whether audio is recorded. Selecting “off” will disable the microphone and stop the device from recording any sound, while “on” will activate it again.

Quick Access Buttons or Shortcuts

Some dash cams offer a shortcut to quickly mute or unmute the microphone without digging into the settings. This might be a dedicated “Mic” button on the device or a long-press function on a general-purpose button. In certain models, pressing a button on the dash cam while recording will produce a beep or flash a message like “Audio Recording Disabled” or “Mic Off.”

This feature is especially useful if you want to temporarily turn off audio during a personal conversation or a private moment, then turn it back on afterward.

Using a Mobile App

If your dash cam is Wi-Fi or Bluetooth enabled, you may be able to control audio settings through a mobile app provided by the manufacturer. Apps such as Garmin Drive, BlackVue App, or VIOFO Viewer often mirror the camera’s interface and include settings for sound recording. In the app, look under general or recording settings to find the audio toggle.

The benefit of using an app is that it usually offers a more user-friendly experience, with clear icons and descriptions—ideal if your dash cam’s screen is small or the menus are difficult to navigate.

Common Reasons to Disable Audio

Users often disable sound recording for privacy or legal reasons. If you frequently carry passengers or drive for a ride-share service, recording in-cabin conversations without consent could be a legal risk, depending on your local laws. In such cases, disabling audio is the safest option.

Others might prefer to disable it to reduce file size, eliminate distracting background noise, or simply avoid recording personal conversations.

Don’t Forget to Save the Setting

After making changes, ensure that you exit the settings menu properly and save your new configuration. Some dash cams require you to confirm changes before they take effect; otherwise, your new setting may revert back to its default the next time the device powers on.

Always double-check that your dash cam reflects the intended setting by looking for a mic icon or conducting a brief test recording.
