    Cameras and IR illumination

    Hi folks. I have bought 1.3mp usb webcam. Now im looking for sort of IR illumination but stuck. Usual LED's i think will not provide enough illumination, basicaly will be limited to 50m or so i think with huge IR lamp. Perhaps i'm wrong. Now those new 7 class BMW.
    I found these LED's: http://uk.farnell.com/jsp/search2/br...questid=688798
    The new BMW: http://www.youtube.com/watch?v=-3uaTyNWcBI

    if you need IR leds, i know nitemaxmax has some spares from his cameras. These are 15 LED arrays and they're top notch. But yeah, search. any Nitemax thread is just chalk full of information and people toying with it.

    Search is what i do first cause most i like to figure out things myself. Now i have CCD CCTV night cam with LED array but the image is crap at night. I figured that the BMW is using a thermal camera not som kind IR illumination,thats why the image is good but the price is good to. Anyway will see those Nitemax
    Cheers

    yeah, that's definitely thermal. IR will allow you to see anything, hot or cold, clearly. Thermal just hot. Its good for spotting mammals. but not as adept as seeing other things in detail

    Tough question. We use IR emmiters that provide about 175M with the highly sensitive cams we use. These emmitters paint about a 30M scene 130M out. Mostly for lights-out crawling at night, not effective above about 40KPH re stopping distance. The units are flat panels about 40x40, but I if you're looking for throw, you may have to install a set or more of IR "fog" lamps with reflectors designed for long IR wave and plenty of input wattage. Low end on these tend to be highly red-filtered halogens. There may be a gas discharge type lamp that's IR - Phillips or Bosch are probably the best sources.

    Considering the rapidly dropping consumer cost for night-vision and the move away from active emmiters by MOD, you might get older but highly useful military surplus cheap.
    Cheers.

    those are IR emitters:

    http://www.epigap-berlin.com/index.php?id=40&L=1

    the ELJ-870-629 and ELJ-940-629

    http://www.roithner-laser.com/LED_HP_multi_chip.html

    LED870-66-60 and the last one:
    http://uk.farnell.com/jsp/endecaSear...ZQ?SKU=1242051
    SFH4230

    What do you think about using these for illumination?

    They are with different wavelength. what wavelength is best for illumination?
    I would like to build some kind o array to fit as foglights.
    Thanx again
