Motion sensor?

Question

as a typical teenager with typical teenage friends, my car gets 'decorated' every once and a while with random food and kotex.

my question is two-fold-

what is a reasonably priced motion sensor recording device i can hide near (or in) my car? one i could preferably hook up to an existing camcorder.

and

how does one get grapeseed oil off of one's windshield? (don't laugh, ok?)

Answer 1

just go to best buy, radio sack.... and ask
