Hi! I am a Lady in need of advice. I have purchased a 4 camera security system and need information on the best way to run the wires from camera in the eaves to inside my home. I live in a Govt rented house so don't want to put too many holes in and not being sure of insulation type not keen on getting in the roof crawl space. Thought i could attach plumbing pipe down the bricks then into the vent at ground level through under the floor and 1 hole to come back through the floor. There is an old satellite areal connection that might be useful but can't move my wall unit yet to check it out. Any thoughts would be helpfull.
