  • Reversing LCD display??

    I have an LCD display that I am installing in the car. I would like to know if there is somewhere that I can install a switch to reverse the image when using it as a rear view mirror and then switch back for my OBDII and GPS display.

    The LCD display is VGA input and I am wondering if that cable might yield a switch position?? OR, since the cameras will be coming through the computer, maybe there is a software solution to reverse the image in the computer??

    If you mean flip the left to right when in reverse, All you need is to hook into the reverse circuit of your car "Example reverse lights" and then interface that into your computer via some like FB or any other method of input.

    Then have the software monitor that input and when it becomes active, have a display driver level switch flicked which will do a screen flip. Depending on what software you are using for the reverse cam you can use a filter/image swap on that before it is displayed.

      If you mean that you need the image reversed, get a reverse cam. They will allow you to reverse the image.

        The details of where to get the signal to flip is not a problem. I will use a switch so that when I am using the rearview feature it will tell the software to reverse "swap sides" I dont want to do it ONLY when backing up. I want to use it for rearview on the sides so I can remove the side mirrors. So using the "reverse switch" wont help. But as I say, the mechanics I have covered.

        What I want is the wire in the vga cable to swap or the software to swap the sides in the computer between the camera and the monitor.

        However, I wasnt aware they had reversed cameras. That is obviously the thing to do. That wont require a switch at all.

        While on this subject, would an infrared camera penetrate fog? Might be nice to have a fog penetrating, forward looking, camera.

          no, the ir would just reflect off the fog. the best use for using a ir camera is increasing night vision range.

          the only option for a camera that might see through bad weather would be a thermal camera-that picks up the heat signature of objects, but those are expensive(I think they start at about $3k dollars, but could be wrong), and I have had no experience with them, so I really don't know if it would work in fog(with the cold dense air everywhere).

            I was thinking of an IR camera with the illumination turned off. This then would be a thermal sensing camera.
