Hopefully I posted in the right section here:
I currently have a media player in my car. I was thinking of also installing a front bumper camera (for parking to avoid scrapes), wherein I could just use a rocker switch to switch the video from the media player to the front camera. I've done a small amount of reading but I'm still unsure of how many connections a single RCA cable has inside, and whether I would need a SPDT switch or a DPDT switch. I also read something about how the cables have a shield; would this need to be grounded out?
I'm going through all this trouble as I'm trying to avoid the bulkiness of having a full on switch box. I only need the video line (one cable) from the media player, and the camera also only has a video line, so if I bought a switch box I'd have 4 extra jacks that were unnecessary. The switch would also be a lot cleaner for the set up I'm thinking of, and I'd be able to hide the switch in an inconspicuous place. Thanks!
