VIDEO DOOR - PHONE SYSTEM

Overview of Video Door-Phone System

Video door entry consists of both outside and indoor elements: a outdoor panel on the outside, an electronic lock release and an indoor monitor. The outdoor panel or street panel is installed beside the entrance door or gateway and incorporates different elements ready for use in any climate conditions: one or several pushbuttons to make the call (usually one per home or apartment), a micro camera adapted for night vision to capture the image of the caller, a microphone to pick up their voice and a speaker to reproduce the voice of the occupant indoors. 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.
