Sorry- forgot the model number of my camera- not sure which one I have- looked on the tags but don't see any listings... either way, mine does not have pan/tilt, so can't test that feature. Let me know if you want me to try anything.
I know that when I first click on the camera from an orbiter I just have a blank (white) screen. Not until I click on where the image would be (presumably to refresh the image) does an image appear.
Not sure this helps...
