I've always been able to see the IR light from those depth sensing cameras used for facial recognition on laptops, as well as those sensors old android phones used to use to detect if they're face down on a table or up to your ear.

It just looks like dark red to me. My science teacher in highschool told me it's not common but some people have a wider spectrum of light thats visible to them than others. This special gift from nature has not meaningfully impacted my life in any way, shape, or form.
