Wireless Mic

ok so I dont have any clue about them but I want I mic so I can film from over the road or something and still hear whats going on eg anyone no how much they cost roughly

They're really expensive dude, notice how he's holding another camera in his hand?

oright and just took the audio from the other cam

Yup.

ok cheers I guess this can be closed then

Really??? :S

Ok then.

Another effective way of doing this is to use a simple recording device such as a minidisk player if you don´t have a spare cam to hand.
