yeah, I would say you need extra hardware. I'm a hobby photographer, but I know nothing about IR photography, but that there are so called IR filters for your cameras (they cost around 200€) and when you photograph with IR you see no matter if it's too dark. The pictures are B/W as I know it, and inverted/negative... That's what I know about IR photography, and my 2 cents goes to the "you need extra hardware" pot
