Double check to make sure that one has sound. Setting it up is simple since it comes with the cable; then plug it in to your TV or VCR. The wireless ones are kind of a bum deal right now because of how short the battery works, many only 8 hours. If it seems trick to setup, I assume you are talking about drilling a hole through the wall for the cable to go through. Just knock on the wall where you want it to go through to make sure there isn't a stud, and you probably only have to go through stucco and drywall.
