Modulate the output of the TV camera (ie, make a mini TV station).  You can
buy cheap Channel 3 modulators like the ones that used to come with video
games for almost nothing.

Put an RF transceiver on the same line using a splitter (connected backwards).

Create an RF transceiver for the command data.  This goes at the
controlling end.  The two directions for data use different frequencies.

Data going from the controller to the camera is in the "forward" direction.
 Data responses (not video) from the camera to the controller is the
"return" direction.

If you want an existing system which can be easily adapted, contact me
private and I'll give you his e-mail.
