The short answer is no - if you're relying on Infrared to be able to see,
it's presumably because none of the visible colours of light are present.
The cameras switch to monochrome (usually either B&W or shades of
green)
so that we can see what's going on. (Showing us the picture in infrared
would kind of defeat the purpose ;-)
