How long does dash cam footage last?

Dashcam footage is typically stored on the camera’s internal memory, which can last for a few hours or up to a day. If the camera is connected to power, it will usually continue recording until it runs out of space or the battery dies. Some cameras overwrite old footage with new footage, while others save older footage if needed. Footage can be kept longer by downloading it and storing it safely on a computer or external drive.
