Topic: Project No Blind Spots
In trying to improve driver vision inside the car I've dived down this insane rabbit hole of adding cameras and screens to our car. Figured I'd share for anyone interested. Note: we're not getting rid of mirrors or anything else, this is just supplemental and a fun project.
So, goals of the project.
1. provide a single location to look at that would give you a 180degree+ view of what is around you
2. do it relatively cheaply
3. Don't discourage the use of other tools like mirrors for the driver.
What I came up with. Three 5" screens and 3 backup cameras. Two cameras are mounted under the side mirrors, and one is mounted to the licence plate bracket. These then feed three screens that mount to the windshield bar of the roll cage and sit right above the existing mirror.
I am using these screens:

There are a bunch of 5" screens on amazon, from $16-$30, they're all the same cheap chinese 480p screen. The resolution is low, but that doesn't matter, you just need to be able to see if there is a car there, not read their stickers.
For cameras, I have two of these for under the mirrors:

and one of these for the back of the car

notice the cameras are all min 170deg view angle. this should give me a bunch of overlap between the screens which should help.
So the easy route here would be to just take things as they are and mount them and run the wires. It would work perfectly fine that way.But I can't do simple, I have to do complicated. So first thing I did was make my own case for the screens. I added a feature that mates to the roll bar tubing and a slot to hold a hose clamp. This will let me mount directly to the windshield bar, not mess with suction cups or other nonsense.
I've since tweaked the model a little to add gussets to those features and strengthen them, but for a test print, that was enough. And yes, PETG strings like crazy on my printer. I don't have those settings nailed down yet.
Next, I didn't want to run 3 video and 3 power cables up the roll cage. So I changed the wiring. I have a triple RCA jack that takes in the video signals, then sends them to a CAT6 Ethernet chord that runs up the roll cage and breaks out into three headphone jacks that feed power and video to each screen. Unnecessary? yes. The wrong connectors? likely. Does it work? yes.
Cable laid out
Testing from earlier tonight
I went with a right angle connector for space reasons
The side camera mounted on a parts side mirror. I have a bunch of varying degree angle shims to align it with once I install on the car for real.
What I have left to do
The rest of my screens and cameras are arriving tomorrow. I have 2 of 3 of the screen cases printed, with the third started. Tomorrow I can wire the screens into the printed cases. I need to print a small box to hold the RCA and RJ45 connectors that will live somewhere under the passenger dash. And then I need to install everything in the car, likely in a couple weeks.
Known issues this will have:
In the wet the cameras will be hit or miss. Since our car is a wagon I already know the back of the car sucks up spray and the camera will be varying degrees of useful. not a ton I can do there.
