I was told if want SCV, must have Lan point. I have 1 Lan point in the master bedroom and also Access Point (yes, wifi very important). I have now decided to place my TV on 1 side of the wall (no Lan point) and now relying on AP to surf, doing just fine. If I decide later to have SCV, will move the TV to the other side of the wall. Yes, option is important, took all these into consideration before hacking commenced. I have also thought through all wifi AP points location, CCTV location, check through existing aircon trunking to see if any leakage, and do these wiring/trunking upfront. Main bulk of the renovation time was spent on deciding on wiring (basically trying to avoid telling myself later on "I should have done this and that" etc). I re-did my flooring, take this opportunity to do termite prevention too.
