The range is probably way too long. I doubt there's enough power going to that camera to extend it even a foot, much less the length of a car.
I wish there was a solution for this, too.
I'm looking to replaced my Nook Color in my car with a Nexus 7 in the coming weeks. Can be seen here One of the things that I wanted to do was a back up camera.
My intentions were to originally do either a BT or WiFi camera but I realized that it would be ridiculous for me to sit in reverse for 10+ seconds while my tablet pairs/connects with the tablet. This leaves me with the only one other option which is to use the front facing camera. I am considering extending the cable by about 9 feet. I have no idea if this will even work because of the length needed.
I think the way I want to do it is by using hot air to remove the connector for the camera from the board, then solder thin wire to each contact. Then in the back of my car, above the license plate, I would have a backup camera housing which would house the front facing camera and some sort of FPC/FFC board allowing me to install the connector I removed from the main board earlier. I would then plug in the front facing camera to the board with the installed connector.
My biggest question at this point is.... Do you think the range is too long for something like this? I drive a fairly small car so it won't be as long as say an RV or something. Here's some of the parts. I was able to find the part number for the connector by using the M370T diagrams floating around the forums.
Camera Side Connector
Below is the kind of board that I would like to find to put into the backup camera housing. The pitch is right but the width is off. I'd have to hunt a little more but I think I can find something that would work.
Kind of what I'm thinking..
Let me know what you guys think. Any input would be greatly appreciated.
This would allow instant results. I never thought about the possibility of using the device in USB host mode. This means that I can run a 4 port USB hub off the tablet too. I could run things like a USB external hard drive as well. I'm sure I can also find a way to use my steering wheel controls as an input device via USB. Recent posts here show promise of being able to charge while in USB host mode.
