not sure if this has been posted before,but has anyone noticed what happens when you look at a remote control through a phone camera(not sure if it works with digi cams too) and press the buttons?

without buttons pressed

with buttons pressed

the beam becomes visable(well the light at least)

Yep it's pretty cool, isn't that how they knocked out a security film in "The Inside Man" with really powerfull infra-red torches?

This is the typical way to test if your digital camera is capable of capturing infrared light (IR). Some digital cameras have a IR filter in front of the image sensor. These can't be used for IR shooting. Other brand don't have this filter.

Security cameras often use high powered IR lanterns to illuminate an area. They use IR as it is not visible to the human eye but is visible to cameras.

Your eyes have a wavelength sensitivity range smaller than a CCD or CMOS.

Your eyes are not sensitive to NIR (near infrared) or IR lights but cameras are. That's why they can capture infrared. But what you actually see in the screen is not IR lights it's just a "representation" of that light.
