When you don’t have access above or below the wall, try to estimate the existing cable and pipe locations from the positions of electrical outlets and plumbing fixtures on both sides of the wall. Also, take a look at the outside of your house, sometimes a conduit, vent or drain pipe will be visible and will offer useful information. Choose the route with the fewest potential obstacles. If your house is built on a slab or you are wiring between two finished floors, look for baseboards which could be removed and replaced with the cable behind them. Doorjambs can be removed and often have enough space for sensor cable all the way around the door (Figure 16).

Sometimes, an under-the-carpet run is possible. As a last resort, heating and air conditioning vents can be used as cable raceways for plenum rated cable (check your local building codes, some municipalities require a conduit)

When you are dealing with the unknown because of the structure of your home, or with difficult materials to patch the wall, such as plaster, lath and plaster, faux finishes, wallpaper etc., be patient. A careful study of the potential problems before you start the job will pay off later.
