I started similar to this but soon realized at least for my case it's better to separate 'system' and then reference one drawing to the other. For example all ELK stuff would be one drawing, all LAN stuff (including IP cams, etc) on another drawing. If not things will soon get too complicated.
But nice work regardless.

I think you did the same as me and took the ELK component images right? or did you download special ELK templates?
