I have never noticed the drop down numbers to the right of the password field in icamsource... can someone tell me what this does? It has the listed options of 1-16... seems to be configurable for each individual camera... what purpose does it serve and where can I find that documentation? There isn't a help document with icam source. (running on mac osx 10.7.2 - icamsource latest update 2.4.1)
