anyone know what kind of draw a baby video monitor (send side not the receiver) would have? I'd like to run mine off the inverter and battery but not sure what kind of life to expect.
You can use a couple of cell phones on speakerphone too, as long as you have coverage where you're camped. Just mute the one outside so it doesn't send any noise into the one in the camper.
years back I rigged one up as a rear view camera and as I recall could operate on D cells so didn't take much power?? of course the picture was backwards and it was a little disconcerting to see traffic passing on the right side when it was just a shoulder of the road. :)
