I have only had my P3P for a couple weeks and I also have anoth P3P that has a broken camera. Is there any other cam I could add or does it have to be the DJI 4K camera? Any help will be appreciated. Also if it can be changed to a diffrent cam is there any videos on a swap? Also could a P3A cam be used on a Pro? Thanks

I know the P3A camera will work, I have seen it done. Not sure about the P3S.

As Captain Salty indicated, only the P3 Advance camera is compatible with the P3 Professional body vice versa. There may be some tutorials out there that were created by other customers, but nothing officially published by DJI.
