This is an excellent question and while we have not been able to physically test this I did a bit of reading on the mentioned model RP50.
It looks like Panasonic utilizes a proprietary control method and would likely prevent our cameras from interfacing with this controller.
If you have any other questions, ideas or concerns please don't hesitate to return to the PTZOptics forums and we'll be happy to help.
We have a Panasonic setup, with a couple of PTZ cameras and an RP50 controller. I'm interested to know whether I could add a PTZ Optics camera to our setup, and have it controlled by the RP50. I suspect the answer is no, but thought it was worth checking.
