Control4 is a home automation company that offers a little more DIY access than the higher priced Crestron and AMX products. Installers like Control4 for homes that can't justify the often high cost of a full Crestron control system.
Control4 has a wide range of control products, and has opened the 4Store, a site where you can add Apps to your Control4 system.
Full control of lighting, HVAC, security, energy management and of course music and video are all possible from Control4 touchpads, control panels, and iPhone/iPad apps.
HomeTheaterReview.com has a preview of Control4's 4Store, as well as a look inside the Aria Resort in Las Vegas that features Control4 and a preview of the second generation of the Control4 operating system.
