Home Automation by Edward Cheung

"This centralized system can control almost all of the lights in my home, a few appliances, the garden irrigation, some window treatments, the Audio/Video system, the security system, and the HVAC (Heating Ventilation and Air Conditioning).

This centralized system can control almost all of the lights in my home, a few appliances, the garden irrigation, some window treatments, the Audio/Video system, the security system, and the HVAC (Heating Ventilation and Air Conditioning). I can communicate with the central computer by using keypads throughout the house, any phone in the world (including those inside the home), any browser over the internet, and from my wrist watch. A webcam (with integral pan/tilt) allows me to see what is happening with nothing but a web browser." - Edward Cheung
