The dashcam works partly like a normal camera. You place it in the desired location and can start recording manually. The dashcam then records what is happening and overwrites the old data after some time. However, important recordings are write-protected.
Dashcams also have a built-in G-sensor that automatically starts recording or saves files in the event of a vibration. Alternatively, some dashcams can also be activated via voice control. In parking mode, they are activated with the help of a motion sensor.
You can then transfer the video material to your computer using a USB cable or SD card. Some models also allow transfer via WLAN. You can delete individual files directly in the dashcam menu
