Lighting

Most houses are still built with light switches, which must be used and triggered in each room of the house. Many light switches also have dimmers, which allow the lighting to be stronger or lighter than the average brightness. A large development of lighting automation is the clip-on, clap-off system. Audio detectors in the system listen for two large audio spikes, most easily triggered by two fast and loud claps. For this system, there is no need for automation control other than being able to make noise.

Security

Home security systems are electronic and almost always automated. These automated systems are usually controlled by a central device which monitors sensors throughout the home including door and window sensors as well as smoke detectors and carbon monoxide detectors in some cases. Security companies usually monitor the system, contacting the homeowners if the system detects an intrusion. Alarm controllers are usually featured near the main door so that homeowners can arm and disarm the system easily when leaving or entering their home. Video cameras are also commonly included in the automation, allowing users to monitor their families and possessions when they are not around typically through the Internet.

Recreational Electronics

Recreational electronics refers to stereo systems, televisions, and things along the same lines. These devices typically have more automated features than those built into the home. The television was among the first devices to have a remote control powered by infrared waves, and quickly after, things like the garage door opener and stereo remote with volume and channel control were developed. Automation for recreational electronics is popular and usually easy to find.
