Backup camera system
I have the tin off the back of my 2002 Wildwood 5th wheel, and want to install a backup camera system.
I found a yellow wire that is for a backup light, and it is not used. This yellow wire goes from the wiring connector (truck-to-RV) to the back of the rig. I'm thinking about connecting the camera to this wire, and then connecting it to a switched 12V wire in the truck, so when the rig is connected and the truck is on, the camera has power. This way, the rear view is always on as I drive.
This takes care of power to the camera. Now the question of wired vs. wireless comes up.
There are quite a few examples of wiring a signal wire from the (wired) camera to the monitor, but they all involve work. I figure about 4 hours. It would be far simpler to install a wireless system.
What is unclear to me is how well they work.
Would you spend the 4 hours and go wired, or wireless?
What is the minimum size of monitor you would recommend? (I'm thinking a 7" one that attaches to the rear view mirror.)
