You may want to add a third or fourth Cat 5 cable to this list in rooms that are data heavy. A Multi-line line phone , motion detector , window magnetic contact , IR sensor and temperature sensor will use up two Cat 5 cables just like that with no room to spare. The third Cat 5 cable can be used for an internal PC network and the fourth could be used for connecting a hardwired TouchLinc touchscreen control or a Kustom in-wall volume controller . We have had customers run as many as eight Cat 5 cables to a room only to find later that they didn't run enough. Any motorized dampers that need to be installed as part of the system will also need cable.
Cable runs outside the house that are exposed to the elements or buried require special cable.
Burial cable which is designed to withstand outdoor exposure should be used to avoid rapid deterioration. In most cases the cable will be run up or down through the wall and then through the attic or crawl space. Never run the cable right next to the 110V or 220V AC wiring or you will get an annoying 60Hz hum on your phone lines, and all kinds of data interference problems. If you are running Cat 5 cable for true fast Ethernet data networking use, additional concerns apply. Things as simple as making too tight a cable bend and pinching the cable excessively can degrade the cables capacity to carry the full data bandwith.
