Why is there no sound from the dash cam?
2 Answers
The reasons why there is no sound from the dash cam are as follows: Mute option is enabled: The mute option is turned on in the dash cam. FM transmission function issue: The FM transmission function is enabled or the transmission frequency does not match the car's radio. Recording function is disabled: The recording function is turned off in the dash cam. Components of a dash cam: Different dash cam products have different appearances, but their basic components include: the main unit, which consists of a microprocessor, data storage, real-time clock, display, lens module, operation keys, printer, data communication interface, etc. If the main unit does not include a display or printer, it should have corresponding data display and print output interfaces. Speed sensor. Data analysis software. Infrared camera, as an essential component for night vision function, is indispensable.
Once while driving, I noticed my dash cam had no sound at all, which was quite frustrating since audio is crucial for recording accident details. Don't panic - the most likely cause is a settings issue. In my case, I'd accidentally toggled the mute switch in the menu. Check the sound options in your dash cam's system settings to confirm it's enabled - this usually provides a quick fix. Also examine whether the microphone is obstructed by dust or dirt affecting audio capture; after cleaning my mic port, functionality returned. Another common issue is software bugs, like outdated firmware needing updates; I recommend regularly checking for update notifications via your phone app or computer connection. A full memory card can also cause system lag impacting audio recording; regular backups and deleting old footage prevents this. Generally, minor adjustments can resolve it - keeping your device clean and updated is key.
