    The ONLY thing that I have a question with is... If the polarity was wrong when hooked up could it have jacked it up and then when I switched it to the correct polarity it not matter because it was jacked up?

    I was going to say a that if you look at the power supply that was supplied, it is showing tip negative (ground) which is the opposite to which it looks like you and jcdillin assumed.

    as to whether you have burnt it out, depends on the quality of the camera, a good one would of had polarity protection.

    FYI - the adapter might not be pulling the right amount of amps to power the camera.

    1.) Figure out the positive and negative wires from the camera
    2.) take an extra Molex adapter (splitter) you may have lying around for your computer and cut off one of the Molex ends
    3.) Identify the 12 volt and ground wires on the Molex. (I think the yellow wire is 12 volt and the red wire is 5 volt - don't take my word for it, do some verification yourself)
    4.) Connect the positive camera wire to the +12v wire of the molex connector and the negative to negative
    5.) Connect the other end of the Molex to your computer power supply and power up your computer
    6.) Enjoy.

    If you've done these steps correctly and still don't see anything from the camera, than it's probably fried. Good luck.

    NOOO!!!!!! Did that and still nuttin.. I didn't plug the video cable in to see if I get anything from it but I hear nothing or see nothing from the camera that lets me know its getting any juice...

    Also, when I hooked it up I got no sparks no smell no nuttin to indicate it was fried... Maybe I just got a bum cam??

    Maybe...

    I would have went the other route first though. Would've soldered together a "converter" for RCA to regular adapter jack, and plugged it in that way, befor snipping the cable off. Now it's too late. Send this guy a couple of emails, and see weather he exchanges it, beecause i think the cam i F***ed up.

    Ok... I'm the newbie here, so this may be a silly question - but why haven't you plugged in the video cable to verify the camera is/isn't functioning?

    Well yea... I woulda done a lot of things different.. First off.. I have one of those adapters that has numerous plugs on the end and you can set the voltage on it.. I woulda just plugged it into the cable but I didn't realize I even had that until I snipped off the end..

    On my AC/DC apapter it has a polarity switch.. How am I supposed to know which one to leave it on? It switches power / ground - ground / power.. And I've used this to test LED's before and it doesn't fry them when I have the switch in the wrong spot.. It just doesn't light them up??
