You are all professional guys for AXIS product, so I don't need to say too much in there.
Just for the lens control board, I need to say I have control software with Chinese menu only.
You can use google to translate manual pdf, or you can build your own software to control it
It use RS485 or TTL signal to control lens zoom and focus, very easy!
Contact me if you have questions about that.
