I'm currently using my Raspberry Pi combined with a No-IR camera module as a camera to livestream my hamster's home to my mobile phone. Now, the IR-camera itself does not output any good pictures at night without an additional source of IR light.
Browsing through the web, I stumbled upon the statement that IR radiation may cause harm especially to the eyes, but also other parts of the body (which I didn't consider before, but sounds pretty logical now).
Now I wonder, would my hamster be safe if he was constantly exposed to such an IR light source? Or would any harm, even the slightest bit, be done to him?
