I asked about that somewhere, but never got an answer other than to buy the model with no IR. I too wondered if the half of it that is black would come off so you could paint it after removing the dome.Maybe I missed it in the thread but why couldn't you paint the black surface white? (Making sure to mask off the up the IRs and such. )
This would be great in my mom's home who lives alone at 84 to check in on her but would pref it was all white.
