iHome Security & Automation System

Home Automation System Home Automation is a field specializing in the specific automation requirements of homes and in the application of automation techniques for the comfort and security of its residents.

Home Automation HAS can also be defined as remote or automatic control of things around the home. An automated home is an intelligent home and an interactive home that takes care of mundane activities, leaving you with enough time to indulge in other activities iHome Security & Automation System

What is X10? X10 is a communications "language" that allows compatible products to talk to each other using the existing electrical wiring in the home X10 is a standard for communication among electronic devices used for home automation, also known as domotics. It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. iHome Security & Atomation System
