hello I have a question, I have to install a dome in a front of a garage with exposed brick, where they recommend putting the tarugo on the brick or on the cement joints ?, the logic says about the cement unions..but the The issue is that there would be a part of the screw outside the tarugo and outside the camera .... and if I install it on the brick it could damage it and generate a fissure where water enters. This is outdoors. Thank you.
