    Post Night Vision/Infrared

    Hi there, I have a 10.4" TFT VGA display and was wondering if anyone has ever seen mini-cams which can do night-viewing mode, or Infrared viewing. I would really like to have the feature that many of the new cadillacs have. Just wondering if anyone knew of a way to implement it.

    There are night vision cameras (that pick up the infrared light too) and they are pretty cheap. They are usually installed for survailance of building entrances, in appartment building entrance intercoms etc. So you will find them in stores with such things.
    You can install one belind the front grill of your car. The main problem you'll have though is how you gonna light the way ahead of you with infrared light. For these short distance applications that I mentioned above, these cams usually have 8-10 small infrared LEDs around the lens. Obviously they are not sufficient for car use so you will have to mount somewhere an infrared spot light (if you want to use it in total darkness- headlights off).
    Keep in mind that these cams are black&white and work in daylight too.

    I hope this isn't a stupid question, but would any old camera work if you just had the IR-LEDs "lighting up" what you were trying to see?

    I am afraid not. Home video handycams only recently start having infrared sensitive CCDs. They are usually marketed as able to shoot in "TOTAL DARKNESS" or "0 LUX".

    We are talking about 2 different things here...

    The IR vision that is on some of the new cadillacs do not require any sort of IR illumination because they are picking up differences from emmitted and reflected infrared energy (heat or reflected heat) in the 7-14 micron wavelength. These detectors are VERY expensive ($5000 on up)

    The Videocameras that have nightshot technology are sensitive to the IR illumination that is required and a completely different wavelenth than heat. These types of ccd detectors do not pick up heat related IR radiation and would be pretty useless on a car unless you could make a set of IR headlights.

    You know...I don't have any fog lights on my vehicle but I have the ports for them They just may need to become occupied by some infrared beams

    ...Wonder how easy it would be to relive a cadillac of its camera in the middle of the night?

    I wonder if you could go to a cadillac dealer and order the parts for the system?

    Just to expand...I was really more interested in having my LCD display heat (as in infrared) images rather than night vision, I live in an area which is occupied by a large amount of deer. Not to mention, while I'm at Penn State, it may be easier to spot the drunk people walking aimlessly along the road Dan posted a good website containing night vision cameras, which he said are also sensitive to IR light? That might work out well...those cameras are only a few hundred dollars. But where to find IR LEDs bright enough to light a few hundred feet down the road...

    Exactly, you have three different things here. What the cadillac deville has, is a scaled down version of what the military contracts out for development with their weapons' guidance systems, etc.

    That stuff works by detecting heat as mentioned. Not only are they normally extremely expensive (easily costing many hundred thousand dollars for military app.) but they also require a lot of cooling to eliminate noise. The uncooled IR varients are relatively new and are a lot cheaper, but are still kinda expensive for the average person to go out and get (if you could get it, afaik they're only being sold OEM)

    The lesser expensive night vision goggles, so called nvgs, work by amplifying light.... i dont think you'd want to have this because you'd be amplifying incoming light (headlights of cars coming at you).

    As for the "0 lux" cameras being marketed by Sony.. CCDs have been sensative to IR illumination for a while, and can affect what the CCD outputs, so in the past they used lenses that helped to block this out. Sony is just utilizing it in their cameras now. And of course as was said here, you'd have to have big IR lamps to make use of this. Out the box, those handycams have ranges of only a few feet iirc.
