dvr to leave in car to capture bump events

this morning I found a dent on my car.
it wasn't there last night when I parked my car.
a neigher told me he saw a car bumping mine.
the driver ran away.

If I could only capture that bump on video, along with the number on that car's licence plate...

I need a dvr device of some kind of that I can leave in my car for hours in order to capture these events.
would need it mostly for day time for the time I park near work.
a motion detection would be good so the battery won't run out so fast.
a solar charging device would be even better.

is there such a device for me ?
