Aug 26, 2003 #2 IRstuff Aerospace Jun 3, 2002 44,353 4 38 US Most such systems use CMOS cameras, which are similar to CCD cameras, being made from silicon and responding to wavelengths up to about 1 um. So, these systems, such as security cameras, use near-infrared LEDs, between 0.78 um to about 1.0 um. These are not true infrared devices, as they are sensing reflected light and not emitted infrared. TTFN Upvote 0 Downvote
