hmm ok, I found some resources on the web how to open the cam - now the problem is that the ir filter and the lens are clued together. what I now need is another 1,25 screwable lens from another webcam without ir filter to adapt it on the spc900nc. does anybody of you know a cheap webcam with 1,25 lens and no ir filter??? already searched on google but can’t find enough info what cam to buy.
