There are "video sender" units that are cheap that can

use the RCA video out (they can run on batteries) - but

the range is fairly limited (I've had good luck with

the picture, but not the sound - but you don't need the

sound...). As for the auto shut-down, it is to save wear

on tape and heads, and some Lanc controllers can restart

the camera...
