It automatically starts recording while the car is on (and shuts off when teh car shuts off)
When it reaches the end of the memory card, it starts recording over the oldest footage.
It has a G sensor, and if there is an impact, it moves the recent 3 minutes into a read-only section of the card that isnt written over.
Any reasonably sized memory card is good enough for several hours of recording, so if somebody does something funny or stupid or future-internet-youtube-star or anything that doesnt result in an impact, you have plenty of time to pull the card and copy it off.
