Kinect2 infrared

I’m wondering about the infrared view on kinect2. i would like to understand why the infrared view doesn’t seams to pick up any infrared light from the sun, i guess it’s related to the fact that it’s using the time of flight system.
I would like to know if it’s possible to emulate that on a standard infrared camera so i could get rid of infrared interference from the sun or a way to get a longer view distance for the kinect2 infrared view, i don’t care about depth sensing here.

not sure , but it can be related to laser’s output wavelength http://openkinect.org/wiki/Hardware_info

Maybe that’s the wave length, the ir would be high and low cut, if it’s just that it might be a good solution to remove a maximum of interference from the sun but i’m quite skeptical about it since the sun emit strong infrared on a wide range.
