Can the front camera be moved up and down side to side like the X4 or X5 camera can be on the I2 or is it fixed looking forward only?

Faces forward and can be tilted downwards. It's stabilised to compensate for aircraft movement, but can only be tilted down manually from the remote control

What Nick mentioned is correct. The main point of the FPV camera is to ensure that you're always aware of your actual heading.

Thanks for the info.  That's good to know.
