Glossary for Home Automation

For most people, there are still some terms we don’t understand about the apps and software we use every day (how many non-geeks know what HTTP stands for, or what a MAC address is?).

If you’re just starting out on your smart home journey, there are some words and phrases it’s essential to understand.

To get understand about lingo terminology in home automation. Here are few glossary for home and automation (words and phrases).


The term automation is the ability to integrate different smart devices together for the purpose to control each and every one of them from a central hub.

For example, most smart cameras and smart doorbells have two-way talk, so you can see your guests through a video feed on your smartphone, and they can speak to you using the built-in microphone.

WEP and WPA Security

The effectiveness of a wireless home automation and security system relies heavily on the network it uses to communicate. In most cases, it is the customer’s wi-fi network. For the purposes of installing your system, you need to understand Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) security.

2-Way Lighting
