An intercom (intercommunication device), talkback or doorphone is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network (Azori 2016).

Intercoms are generally mounted permanently in buildings and vehicles.

Some intercom systems incorporate control of devices such as signal lights and door latches.

A smartphone is a mobile phone (also known as cell phones or mobiles) with an advanced mobile operating system that combines features of a personal computer operating system with other features useful for mobile or handheld use.

Smartphones, which are pocket-sized, typically combine the features of a mobile phone, such as the abilities to place and receive voice calls and create and receive text messages, with those of other popular digital mobile devices like personal digital assistants (PDAs), such as an event calendar, media player, video games, GPS navigation, digital camera and digital video camera.

Smartphones can access the Internet and can run a variety of third-party software components ("apps" from places like Google Play Store or Apple App Store).

They typically have a color display with a graphical user interface that covers more than 76% of the front surface.

The display is almost always a touchscreen and sometimes additionally a touch-enabled keyboard like the Priv/Passport BlackBerrys, which enables the user to use a virtual keyboard to type words and numbers and press onscreen icons to activate "app" features.

In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other.
