The differences actually lie in the support of a camera that was introduced at that time, the Model WV-CS85A. This was the first camera in the Panasonic line to offer extended "Q" mode functions, which are too numerous to mention here, but include fine pan-tilt-zoom control with proportional control. All Pana PTZ cams to date (WV-CS865B, WV-CS954, WV-CW864A) all offer these extended features and then some.

Keep in mind that you can still access 8-step mode control with the non-"C" controller (backward compatibility). However, as a rule, you should avoid incompatibilities if possible. Good luck with the products.

Anyone know what the difference is between the two? Same with the WV-CU360 vs WV-CU360C controller. C model newer? Thx.
