Installing mount for Stickup camera

I just got a stickup camera and spent an extra $19.99 for what I thought was the pan-tilt mount. However, it seems to have pan-tilt capabilities without the extra mount and I've been searching all over to try to find out what it actually does, whether I even need it, and how to install it if I do need it. I refuse to call the abysmal customer support again so I'm hoping for some help here.
