• Video door entry (also known as a video intercom or video door phone) 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. Display: Coloured 3.5" / 5.6" TFT-LCD, Telephone Handset, Door Unlock function, Panic Button & 1 Zone Alarm Function, Optional Loud Siren connectivity, build in SMPS.
