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.

I was thinking about getting something like this: IR LED Light Ring Board

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?

Hamsters can not see this wavelenghth of infra red radiation.

The vision of hamsters are shifted more to the ultra violet part of the light spectrum,this means they see best in the blue to green light and are less sensitive to red and infra red light.

The infra red LED diodes on the led board you ask about have an output of 3 watts in the 940 nanometer spectrum,High intensity infra red light can be dangerous but the one you have there is not harmfull.

I doubt your hamsters are able to see 940 nanometer infra red light at all,But you need to keep an eye on them and if they show signs of stress you need to remove it.

You need to place the infra red light at no closer than 1 meter from the cage to be totally safe that their vision is not harmed in any way(I do not think there is any risk in using ir light to film your hamsters,But it is better to be safe than sorry).

  • Better safe than sorry nails it. The thought behind this is that I can watch him do hamster stuff during night time without distracting or disturbing him by being physically present. The last thing i want is to hurt him in any way, but the way you explained it makes me feel confident about it :) Thank you very much for your answer! – rqnn Jul 6 at 14:32
