The dash cam can record sound inside the car, allowing you to hear conversations in the vehicle. Here is some relevant information about dash cams: 1. Purchase considerations: When purchasing a dash cam, pay attention to the following: choose a product with a wide shooting angle and high resolution, which is more conducive to comprehensively recording the surrounding conditions of the vehicle; select a dash cam with good concealment to avoid the risk of window smashing and theft; opt for genuine, well-known brands, which are more trustworthy and offer better guarantees. 2. Description: A dash cam is an instrument that records images, sounds, and other relevant information during vehicle travel. There is a recording button on the dash cam, and turning it on enables normal recording. Currently, most dash cams on the market come with a recording function, which is a standard feature for the majority of them. Of course, since the interior of a car is relatively private, some people may not prefer recording. To ensure privacy, the recording function can be turned off in the settings interface.

I also struggled with the recording issue when installing my dash cam before. Actually, most devices come with built-in microphones that can capture audio, but privacy is something to be mindful of. Last week, my conversation about salaries with a colleague during the drive got recorded, and now it's spreading like wildfire in the company. I recommend turning off the recording function, especially when picking up kids—their private chats with classmates shouldn't be captured. Some brands require navigating through three-level menus just to disable recording, so I specifically chose a model with a physical switch on the side when buying car accessories. Now I can easily toggle it at red lights with a swipe. The key is to ensure it's truly off—I once saw news about someone's dash cam secretly recording a couple's conversation late at night.

It depends on both the equipment and regulations. My front and rear dual-camera dash cam features ambient noise reduction technology, which can clearly record conversations even with windows down on the highway. However, last year in Shenzhen, I was almost fined when caught recording with a friend in the car, as recording inside a vehicle without everyone's consent is illegal in this city. Now I've developed a habit of checking three things before starting: normal tire pressure, dash cam muted, and charging cables not causing tripping hazards. Noise reduction is crucial when choosing a dash cam—my old one's fan noise was like a swarm of bees drowning out voices, and a friend even suspected me of eavesdropping when borrowing the car.

When choosing a dashcam for my child's car, I deliberately picked one without a microphone. Imagine how embarrassing it would be if the conversations of kindergarten teachers catching a ride were recorded and leaked. Once, while reviewing footage, I was startled to hear my own child crying in the car seat, saying they hated piano lessons—all captured in the audio. Now, laws are gradually improving, with many regions requiring dual-recording labels to be displayed on the windshield. Devices capable of recording audio are like having an invisible passenger sitting beside you—it's something to consider from another's perspective.

Technically, it's certainly possible to record audio, but the pros and cons need to be weighed in practice. I've seen cases in my auto repair shop where disputes arose after a dashcam recorded conversations about mortgage loans when the customer's car was lent out. The key factor is the device model: single-lens models generally record audio clearly, while the microphone placement on panoramic models varies widely. New traffic regulations require clear notification to passengers about recording status. My approach is to place an orange sticker near the AC vent that lights up red during recording. For important conversations, muting isn't troublesome - setting a custom button on the left side of the steering wheel for one-touch mute is the safest option.
