Quick question. I have been googling around and am not really finding what I am looking for. I have several old phones and tablets around. I have a Travel trailer that I would like to incorporate a back up camera into. My thoughts were to either use an old phone as a monitor for Video-In from camera. Or (easier choice in my opinion) would be Temp Mount an old phone to the rear of the trailer and use current phone as a receiver for the video. Is this possible over Peer-to-Peer Wifi or Bluetooth? At home backing up I could have both phones on my Wifi. Out camping I will not have that luxury. Any Option? Thanks!
