The current definition of a "drone" is a remote controlled vehicle with a camera mounted of any kind on top.
Is that the actual definition?
Solution seems pretty simple, just mount the camera on the bottom.
Another option is to check the law regarding planes towing planes.
It maybe possible to get around the law by "towing" a platform with the camera mounted on that. This way there's no plane which is both radio-controlled and contains a camera.
Seriously though, your best bet is to get lots of FPV flyers in your area to sign something and officially give it to your local government body. Even better if it's from a model club or something.
As well as everyone's signature, put forward in the document lots of solutions to the problem which benefit everyone and still allow FPV flying.
Getting radio/tv news coverage will also help.
