control logitech ptz camera pan/tilt using c or c++ o

hi, i am doing a project and is sidering to use a logitech ptz camera.
is there anyone who knows how can i control the built-in servo motor using c or c++. i already finished the code for face recognition, the camera can recognize human face and put a rectangle on the face.
the problem is can i control the built-in servo motor of the camera so that it will automatically pan/tilt when the face is moving.

thank you in advance!!
