webcams — 2 Comments

  1. All webcams are infrared (and visible spectrum). You can turn any webcam into an infrared camera by putting a suitable filter (exposed camera film will do) behind the lens.

    Google: “make your own infrared webcam”
    or “make your own ir webcam”

  2. Yes, I found out about that on the net.

    Although some webcams has infrared filters behind the lens, so you need to make sure you remove the IR filter, then put the visible filter in its place.

    Apparently, some are even worse: the infrared filter is “sprayed” onto the lens… scraping the IR coating off the lens can be a real pain!
