I'm planning on a security camera install. All of the connections will start from the 2nd floor and go to some cameras on exterior at the ground level. The 1st floor has a roofed deck that extends out from the main house. Because of this I'll either need to bring the wires through the 1st floor roof, or run on top to the edge (~7ft from the side of house).
What is the best way to send the wiring from the 2nd floor down to the ground level?
I might be using a conduit on the 2nd level, and then transition to exposed wires when under the covered deck.
Looking for suggestions on how to approach this other than putting a hole in the roof and sealing.
