Video door entry system
Landing calls.
The system enables making both audio and audio/video external stations that can be used, for instance, on the
landings of condominiums through which people pass to access the door for entry into the apartments.
The audio speech unit is made with the call button 20577 or 14577 while the audio/video one is composed of the
same call button with which a video camera is combined (art. 20560, 14560 or 20565, 14565) with the opportunity
of adding also the LED illuminators (art. 20570, 14570) if the environmental illumination is not enough.
Finally, to make the audio/video call from the landing, it is necessary to use the audio/video interface for video
cameras 69AM (see the chapter "AUDIO/VIDEO COMMUNICATION FOR LANDING CALLS" of this manual).
