Incase some don't know a converter box is needed to tranfer digital into analog so that people with older TVs can watch over the air TV. So, obviously there's no need for a camera and a mic to be in a converter box. Just like they arn't needed in a rabbit ears antenna.See video below. http://www.liveleak.com/view?i=6e3_1235024071 Don't know if this is real or not. Should be checked out. Edit: I'm thinking this is untrue cause if some group were to do this on a wide scale they'd probably be able to get much smaller cameras. Undetectable. Dunnoe.
