Most of our V2s are looking out windows and the white body makes a noticeable reflection in the recorded video at certain times of the day. So I used a large Sharpie Pro to color just the fronts black.
No more annoying “whitewash” reflections in the glass and @fabulous is correct - they blend in so much better because they don’t look at all like cameras any more. With no distinctive round black lens showing up on a white background, they are just nondescript black squares in the windows. Even against white window treatments, they do not scream “SECURITY CAMERA HERE!” any more.
I left the rest of the camera stock white/gray to possibly reflect heat better.
Anyhow, my $0.02 worth is that it’s a lot easier to change the color of a white plastic camera with almost any color magic marker than it is to change the color of a black plastic one. And it takes all of two or three minute to do, even for someone as un-artistic as myself. The only trick is to let the permanent ink dry before carelessly handling the camera.
So I think the current white cameras offer more flexibility in concealment and blending in - when that is desired.
