Back up and Side View Camera Systems
Anyone have any recommendations for a decent back up camera system for a Class C motor home? I do not want a wireless unit. I am looking at the Voyager VOS74TQ Observation System. Anyone have exper...

Hey, Muddydogs and NeedAvacation, would you care to cooperate on this camera/monitor install?
I have the monitor already, record time for free shipping from China. I see the monitor has red and black wires, not much doubt about those, though it would be nice to know what voltage is expected. What the heck is the green wire for?
Two coax leads, with RCA connectors, one of each gender. Trial and error on those, I guess.
Read the details on Amazon. Some unfavourable comments - poor resolution, color and some buyers got duds.
The extra wire allows switching on/off while leaving the power on all the time. Not sure what that means but it suggests connecting the green to positive to power both simultaneously.
The two video connectors are for two cameras or other inputs, switched via the remote, I guess. Good news.
Power supply 9 to 24 volts.
As you figured the red and black wire are you typical pos and neg connection. The green wire is also a power wire, kind of a power switch override if you will. In a typical backup camera use the green wire is hooked to a power source that only powers up when you put the rig in reverse so the monitor will come on when backing and shut off when not in reverse. Easiest way to handle the green wire is run it back to your reverse light and wire it as well as your backup camera into the light. I didn't hook up the green wire as I only use the backup camera when hitching up plus I forgot about the wire until after I had the other cables ran. If you are not going to use the green wire leave it unhooked.
Yes this is a 2 feed monitor, there is a button on the face of the monitor to change which feed you want to see. I hook both my trailer camera and truck backup camera to the RCA leads and just switch to the one I want to view. The female to female adapters I think I linked in my write up work on the male lead. I think the remote switches the video feed as well as the switch on the monitor, I have never used the remote as my monitor is within easy reach of the drivers seat.
