I have just recently added a second PTZ to my Eyemax NVR, and using the IDMSS iphone app. and for some reason can only get one of my PTZ's to function properly. I can see them both but can only get one to zoom and move around. one PTZ is an Eymax ip cam the other is a Axis ptz. Question does IDMSS have an issue with connecting 2 PTZ's because they both function from the NVR ?
