As well as moving 90/180 degrees vertically  Do your Bullet cameras In general also move left & right please. 

Asked by: Toejam237
While there is no left and right axis, there are two points of rotation, one at the base and one at the camera either side of the pivot joint. Adjusting all three in combination can allow the camera to point in a variety of directions including straight left or right.
