Guide
Many dash cams can record cabin sound through a built-in microphone, but audio can usually be disabled. For work vehicles, the ICO says audio should generally be off by default and used only in exceptional circumstances.
It depends on the model and its current setting. Many cameras have a microphone that can add cabin audio to video files, and some arrive with it enabled; check the recording icon and manual before your first journey.
Look for an audio-recording or microphone option in the camera menu or companion app. Some models also provide a physical button or voice command; confirm the muted symbol appears and remains set after a restart.
Sound may add context to a private incident, but it also captures passenger conversations. Use the least intrusive setting that meets your purpose and tell passengers when recording could reasonably affect their privacy.
If you operate work vehicles, document the purpose and lawful basis, provide clear privacy information and assess whether a DPIA is required. The ICO advises switching audio off by default and limiting it to exceptional circumstances.
Make a stationary test recording, stop the camera safely and review the clip. This confirms whether audio is present without interacting with the device while driving.
Common questions
It can if its microphone is enabled and close enough to pick up speech. Disable audio if you do not need conversations in the recording.
Usually yes, through a microphone button, camera menu or app. Confirm the setting in the manual for your exact model.
Context matters. Personal use and organisational monitoring are treated differently; businesses need a lawful, necessary and proportionate basis and clear information for people recorded.
Not necessarily. Speaker volume controls alerts, while the microphone setting controls captured sound; check both separately.
Keep exploring
Start with the coverage you need: a discreet front camera for the road ahead, or a front-and-rear system for evidence from both directions. Our guides then narrow the choice by installation, connectivity and brand.
The Nextbase 622GW is our balanced UK pick for its detailed recording, stabilisation and accessible touchscreen. Garmin Mini 3 suits a discreet fit, while VIOFO A329S covers the front and rear at high resolution.
A dual-camera kit is the direct choice when you want the road ahead and traffic behind in the same recording system. Check rear resolution and cable length, not just the headline front-camera specification.
The 622GW has the strongest recording specification in this trio; the 522GW keeps the large touchscreen and polarising filter at 2K, while the 322GW covers the essentials.
