CCD and CMOS sensors are sensitive to IR so all WebCams, all video cameras using
them have a small IR filter between the lens and the sensor. Remove the filter
and BINGO! Instant IR camera!

Have a nice day!

You give me an idea: i have a few old TV remote control here. I will try to use
their IR-LED. Not too difficult to mount inside the CAM. Three of them in
series will probably work fine with the 5 volts available...

Thanks!

To be able to actually see anything more than a foot or two away,
you will need a bunch of IR LRDs like below.
