Can the Dash Cam Record Sound?
2 Answers
By default, dash cams can record sound. Below is an introduction to their functions and classifications: Functions of Dash Cams: A dash cam is an instrument that records images, sound, and other relevant information during vehicle travel. After installation, it can record the entire driving process, including video images and sound, providing evidence for traffic accidents. For those who enjoy road trips, it can also be used to document the journey through challenging terrains. Classifications of Dash Cams: They are mainly divided into two categories: portable dash cams and aftermarket in-dash DVD dash cams. Portable dash cams can be further categorized into rearview mirror dash cams and data dash cams, which are characterized by good concealment, easy installation, detachability, low cost, and simple operation. On the other hand, aftermarket in-dash DVD dash cams are usually vehicle-specific and come in two types: pre-installed and post-installed. Installing these cams is more costly and challenging, but they maintain the aesthetic appeal of the car's interior. Additionally, some luxury car models come with pre-installed dash cams from the factory.
As a veteran driver with nearly 20 years of experience, I can tell you that many dash cams can record audio because they have a built-in small microphone that captures both in-car conversations and external noises. However, not all models have the audio recording function enabled by default. You need to check the settings menu to make sure the microphone is turned on, otherwise it will only record video without sound. I remember one accident where the audio recording helped clarify liability, but privacy is a concern—private conversations in the car may be recorded, so I recommend turning it off or covering the lens when parked. Choosing the right brand is also crucial; higher-end models offer better sound quality with noise filtering to avoid unclear recordings. Regularly check the device to ensure the microphone isn’t clogged with dust, which could mute or distort the audio.
