I actually used the balcony near the front cam, as a storage area after our move, and renovations. There was a half size step ladder there, which my camera was one, I just drapped a t-shirt over it to prevent reflection. However once wife made me clean up, needed make a mount, and hiding it was two fold, she did not want to see the camera and I did not want reflection. When zoomed in, the box looks pretty big, but from the ground level its not too noticeable.
Speaking of pop solutions (see my diet coke usage) This was my attempt at stopping bounce back reflection of ir led's prior to my camera manufacturer finally doing a firmware revision to turn them off. I cant find the reflected images anymore, but any evening or night shots had a halo of 12 bright led's.
None of these solutions worked. You could see the led's through the sock, like it was not even there. DC case as well. Even with metallic tape on backing, the light bled through. Kray's holey black sock reference reminded me of these pics
