Blender how to bind geometry to camera PLS HELP Tweet

[WIPEXPO]

Hi i need to render about 200 seperate booths - 1 camera for each , output has to be .png wih alpha.
what i want to do is set batch render and do it with 1 go (i ll key frame cameras witch hdri light coordinations)

I thought off puting kinda object (box,empty) over each booth and make each camera to render only geometry that lies inside or put some section planes beetwen each geometry and aplly it witch shadow chather but without shadow on it (not working as i want it to)
any idea how to do it ?

Sorry for my engl.
