Have a 14' high exterior wall and want to mount a camera.  Had thought about putting it under the eave and it would be somewhat weather protected there but that's quite high.  If I mount it lower I am thinking about the best way to do it.  Wall is 2 x 6 studs.  Could use a short section of PVC conduit or similar to make a tube through the wall and shove some insulation in it after the cable is in.  New construction so the walls are open now but want a way to replace the camera in the future without tearing too much apart.  Cables visible inside isn't an issue as it's a garage.  Walls will be insulated and will have sheathing on the inside (plywood not drywall).
