I think I should get a backup camera. Almost took out a post a few days ago.
I've seen a bunch online, and the most basic ones seem pretty similar: camera, connection to small LCD monitor. There are wired, 2.4 wireless, and even a wifi camera (sends to your iOS or Android device; pretty nifty).
I have some cameras, cabling, and other junk laying around, left over from other projects. I've got a security cam with IR LED lights and long runs of AV/power cable for that with BNC connectors. I've also got an old helmet cam, a Sony lipstick model that has pretty decent resolution for an older format camera. It runs on 12v and outputs to an RCA or BNC jack.
I figure I could mount up either one on the penthouse, or rain gutter. There's 12v back there from the trailer connector (I should probably make a permanent power takeoff from that somehow) so I've got power. My big question is the LCD screen. I see small 2+" screens at 4:3, 4.3" screens, 7" screens at 16:9. I can't think what else I'd use with them, but I'm wondering about resolution. Do I have to look for one with a certain resolution? Security cameras all seem to have a different way of listing that than other cameras for some reason. Also, many seem to have both DVD and backup cam connections. Does that mean the backup connection will automatically be reversed? That would seem to be a necessary feature
And while I'm at it, anyone have any experience with completely portable wireless ones? There are a couple for connecting to a trailer hitch, but the ones I saw in campgrounds had a much narrower field of view than back up cams. But I would think it would be really cool to have one you could also mount on your FRONT bumper for those moments when lining up tires four wheeling is essential. Maybe there'a a baby monitor one that runs on batteries or something.
Any advice appreciated.
