I hope you can help, I am having difficulty adding a PTZ to my system. I have owned a Defeway D08AHD1 for a couple of years using a couple of fixed cams with no issues. Now I have added a PTZ and although I can view the PTZ cam, I cannot control it at all. My PTZ camera is: Maxx Digital AHD 720P 1.4MP 60M IR PTZ CCTV Camera 10x Zoom (MDH-PTZ-C130) I have wired the PTZ correctly to the RS485a & RS485b. I have selected the PELCO_D protocol on the DVR and baud 2400 The PTZ cam protocol is "auto". When I originally got this and hooked up the fixed cams, they were pretty much plug & play. I know nothing about cctv and suddenly feel way out of my depth, I would be eternally grateful for any assistance Andy
