OK, it seems the solution is quite simple. Find these lines in the script (there should be four of those similar combinations, which stand for 4 camera positions, right, left, back and front).
camObj.setLocation(xx, xx, 12.2)
camObj.setEuler(pi/4, xx, xx)
Now change it to something like this:
camObj.setLocation(xx, xx, 2.2)
camObj.setEuler(pi/2, xx, xx)
You might have already figured out, 12.2 was the z offset of the camera and pi/4 was the camera's pitched angle.
