I have one or more security cameras in the room in which I sleep. No, I won't tell you why. They have IR illumination LEDs that operate in darkness. The wavelength is in the near infrared. Somewhere between 850 and 980 nanometers.
Although not perceivable by the human visual system (eye, visual cortex, et cetera,) I wonder what effect this light have on sleep via the melatonin pathway. Perhaps although not visible; it is still perceivable.
Thoughts? Or even better, a citation on effects?

Other than it would creep me out to use a camera in the bedroom, I don't think near infrared has any documented affect on sleep, and it is used by sleep labs as well. If there was an issue, I'm pretty sure it would be discussed in the literature.
