Wireless Video Cam? Is such gear available?

Hi,

Can someone recommend suitable equipment for wireless video shooting?

The idea is to have a percussionist wearing a helmet with a camera.  
This guy will play with brushes on a canvas that is prepared with  
contact microphones and amplified through the PA. He will also use  
colors and "paint" while "playing". A big screen will project his  
canvas over the stage. This guy will also (hopefully) through himself  
into improvised adventures among the audience and whatever he turns  
at will be filmed and projected to the big screen.
