Modern phones don't see IR very well on account of improved filters. My iPhone can't see remotes at all. An IR source needs to be much more powerful to show up.

Back in the day I took the IR filter out of my digital camera and got some cool (dismal 3.2MP resolution) shots.
- photojosh 9y agoThe rear camera has a very strong IR blocking filter. But the front camera doesn't. (We have a product that uses IR LEDs as a flash, and I use my front-facing camera to verify they're working.)
