If you're keen on installing a dashboard camera, go with a crash cam

Crash cams only start recording for a small window of time in the event of an accident.

Drivers who are interested in recording their commutes or travels with a camera for their car or motorcycle are best off with a so-called "crash cam". These cameras only start recording for a small window of time in the event of an accident.

As Anja Smetanin from the major German automobile club ACE explains, the memory card in these cameras is also constantly being overwritten, so that you don't run out of memory or end up with days and days of footage.
