Smart houses are a favourite of people who are focussed on security, and ease of use. Remote camera systems are commonplace in many homes, made popular by 'nanny cams' but have steadily evolved into full coverage, remote IP CCTV. Being able to use your mobile phone or tablet to see if the back door is shut is fantastic peace of mind for anyone travelling for work, but the personalization goes leagues further than this.
Programmable machines have been common for many years now, from coffee machines to entertainment systems, all can be customized to some extent. But having a smart house takes this one further, what if they devices in your house turned off automatically when nobody was home?
