Hello!
It depends on your room configuration, USB-cord limits, available tripods and/or wall bindings, etc. As a rule one starts from scratch and adjust cameras to satisfy the following requirements:
- Actor(s) should be fully visible in all cameras during performance.
- Actor(s) image should be big enough (height of actor image in camera should be at least 30-50%% of total image height). That is cameras shouldn't be too far away from each other.
- At least two cameras should be placed at 2.5+ meter height.
P.S. If you're still in doubts, you can publish here or send to us by e-mail screenshot of iPi Recorder when actor stays at the center of capture area. Based on it we'll answer is it ok.
