Is there a technical reason why ARC can only support a single camera control? I have more than one camera, and I wanted to have different things happen depending on what the camera sees. ie. seeing a specific color or glyph, it would follow. Motion, it would track, but not get too close, and a face would start a whole different set of actions including triggering a VB script which would email or SMS me so that I can remotely take over manual control (should not see a face if I am not home)
I haven't looked too deeply into scripting, so this might be possible with only one camera, but would be easier with two controls I think.
