The problem with this piece is installed in walls drilling jobs. First, I would use a large auditorium, a small haystack da, but enough to see established. The room is too narrow, and the walls of the room can not penetrate walls, and then another one, then another side wall is glass, difficult to install, and it works as projected, if the room is too bright to make a projection of the video clearly?How to fix the problem is to move the installation all work up to the 3rd floor, because the walls can be drilled and is off dark, projecting video clearly j and spacious setting, is not too cluttered.
