    Sorry for my ignorance but that LUX means is night vision right?

    No, sensitivity of the camera to light. The lower the LUX level, the less light it needs for a good image. So cameras with lower LUX work better at night, but all cameras have a LUX level.

    real crappy cameras may be rated at 2 lux, maybe even 1 lux might be considered half way decent, but not good. a good camera will be like .02 lux, some get better than that, if there is no rating listed I would avoid it... a cheap camera will suck at night... think of cell phone cameras, they might take a halfway decent picture with a lot of light, but once it gets just a little dark they suck.

    be careful with infrared cameras, they can pair a crappy (2 lux) camera with the infrared & then claim 0 lux, but that's bull cause the range of the infrared is very limited, especially on a cheap camera, for a usable range of like 20-30' you'd need a whole array of infrared leds...

    I second the warning about IR "0-lux" cameras. They often have a very limited range of IR light. Think of a camera with a pen-light attached, it can only see what is right in front of it. Although some are better then others.

    The lowest native LUX camera is a Sony SuperHAD CCD. Black and white with a rating of 0.0003 LUX. Supercircuits sells one for $110 ($90 without a case) that does this, I have it as my front-door camera at my house. Basically it can see better at night then you can even after your eyes adjust.

    Like always though in the end you get what you pay for...heck SS sells a $12 camera. Although they also sell at $18 B/W camera with 0.01 LUX and 70FOV that I want to try out, it may be cheap enough for some fun applications.

    I wonder how low lux the nitemax b/w camera ccds are. They are SuperHADs (ICX054BL), oddly enough, the datasheet doesn't say so I'm guessing what ends up determining LUX is more then the CCD itself.

    I think the ccd is the determining factor as far as I know...

    & yeah, really low lux cameras are great in the dark, I look out my back window & see nothing but darkness, but on the camera I can see everything plain as day, without infrared assist.

    infrared really isn't useful unless you need covert operations, & really has no good use in a car, the range is limited & a small backup bulb with a good camera should be all that's necissary...

    Hmm. No idea.
    Maybe to drive something else off the camera? Only thing I could think of is a video-type auto-iris, but that doesn't seem right as I would guess (can't tell by the profile pic) it doesn't have an external lens.
