How long do dash cams record for?

Dashcams typically record continuously as long as they have power. Some models may have motion sensing or manual event-recording features, so they only start recording when triggered. Some higher-end dash cams can be hardwired into the car’s electrical system or come with built-in batteries, allowing them to continue recording when the car is turned off. Extended recording requires a lot of storage capacity, so a suitable memory card is important.
