Hi, I have a 1938 build house that was fitted by the local council with brick slip cladding in the late 80's. The cladding is 3" of polystyrene with fibreglass coating and brick slips glued onto it. I am trying to figure out how to secure a CCTV camera to it, not a big one, just a TP link unit. I have used cavity wall fixings with various degrees of failure over the years to hold cables etc, but I want this to be secure. I figure I could use things like window framing hammer in mounts, but not sure how solid that would be. Thanks
