Video Door Phone

Video door-phone (also known as video door entry or video intercom) is a stand-alone intercom system used to manage calls made at the entrance to a building (residential complex, detached family home, workplace, etc.) with access controlled by audiovisual communication between the inside and outside. The main feature of video door entry is that it enables the person indoors to identify the visitor and, if (and only if) they wish, engage in conversation and/or open the door to allow access to the person calling.

There are several variations on this basic format. In addition to outdoor panels with one pushbutton per apartment, it is possible to find others with a numeric keypad: in this case, designed for large residential installations, the homes are identified by codes. Others have built-in cardholders panels or even small screens to guide the user or facilitate entry for people with disabilities. Some video entry monitors have an earpiece similar to a telephone handset, while others are "hands-free". Other examples are monitors with memories which store an image every time someone calls at the door or touchscreen video entry systems.

When a visitor presses one of the outdoor panel pushbuttons, the built-in camera is connected and the image captured outdoors appears on the monitor screen. Connection takes place automatically with no need to activate the equipment, which is one of the essential elements of video door entry. As of this point, the person inside the building can open the door if they wish or begin a conversation, which is usually secret (cannot be heard by other users of the same facility). The equipment also disconnects automatically after a set time has elapsed. The video entry system as a whole runs on low voltage energy from the building’s trunk.
