Hi There, got a problem with a PTZ system comprising of joystick controller,DVR and four PTZ domes (pelco d). System works fine but quite often when panning a ptz then releasing the joystick the camera keeps panning and the only way to stop it is by selecting another camera. The problem occurs intermittantly and usualy when panning at slow speed. The system cabling is "star" configuration with the termination resistors in the PTZ furthest from the controls. Any suggestions would be gratefully appreciated please.

I assumed you needed resistors wether star or daisy chain? using 9600 baud, a pair for each camera

Thanks but tried a different controller even, same problem. Was thinking maybe something wrong with the control wiring or termination resistors. Wnder if anyone else heard of this problem?
