Security cameras use IR illuminating LEDs. At the lab where I work we have video eye-tracking hardware that uses a 4x6 array of IR LEDs to illuminate the subject's eyes.
I don't think it's a problem unless you get into significant intensities, as per a >1 mW laser.
Are there other commercially available cameras that already do this out 'in the wild' (ie am I already hit with these daily, I just don't know it)?
What are the health implications of it (if any)?
