What To Do. Buy camera. I bought the Logitech webcam 200,
Remove the rubber plug on the side, take out the screw.
Split the camera apart.
Unscrew the lens from the frame that sits on the circuit board.
Unscrew the backside of the frame from the circuit board.
Remove the red glass that is in the frame, It may break, just clean it out good. (thats the IR filter)
Cut out a small filter from the floppy disk or film negative and put it over the lense
then put the camera back together.
