the bedroom floor is polished cypress pine floorboards. the ceiling of the room underneath is gyprock. there are no openings in the floorboards or the ceiling and I am thinking the best way to confirm what is in there is using an inspection camera. it is possible there might be a slit opening in one side of this "ceiling space" ...and I could get a camera in there.
I am looking for any recommendations about which camera to buy and or is there a better way. I can't find any entry point so can only think the possum /whatever is in there, gets in via the roof and then comes down to this space via a stud wall cavity that permits entry.
