Connecting a Door Intercom System
Overview
Door intercom systems with an a/b interface and IP door intercoms
can be connected to the FRITZ!Box. Then you have the following
options:
• You can answer the doorbell on your telephones, speak with visi-
tors, and open the door, even on a mobile telephone or another tele-
phone connection away from home.
• You can have the camera image from your door intercom system
displayed on FRITZ!Fon telephones with a color display.
• You can configure a special ringtone to signal the doorbell on a
FRITZ!Fon.
