There are different frequencies used by TV Remote manufacturers...
I've seen the dim glow of the IR LED in TV remotes and Video security
Camera IR ilumination... Those are 850nm LEDs...
I can also easily see 808nm Laser light..
But in ALL Laser cases I look at those wavelength by observing the light
reflected off of a diffused mat surface...
NOT DIRECTLY INTO MY EYE in the case of the Lasers...
So basically you're just curious about the sensitivity of your own eyes...
BTW... here is a link to an IR Indicator Card... You can probably find
others less expensive...
