A simple PTZ camera controller we created that uses a subset of the the Pelco-D protocol to communicate with and control security type cameras.
There's a nice mouse controlled proportional PTZ 
			circle to move the camera in any direction and at your selected 
			speed, as well as "Preset" buttons and camera OSD Menu access too!
