Setting up vlans is pretty easy.In your case, as long as you set it up so that your MainVLAN can initiate communication with your CameraVLAN, all those devices you mentioned would work normally with regard to how they interact with the camera server
Configuring them in this way is probably the better way to do it but it is more complicated and easily messed up.
Multihoming the bi server would be quicker and easier if doing it this way proves too much.
