3.4 Configuration Example
The following example of a door intercom system demonstrates one possible ap-
plication and shows the steps for properly configuring a MOBOTIX D22M with an
ExtIO using a USB connection.
3.4.1 Functional Overview
A MOBOTIX camera and an ExtIO are used at the entrance of a building for access
control purposes; the camera should also be able to open the door when in-
structed to do so.
If a visitor rings the doorbell key of the ExtIO
, the MOBOTIX camera activates an
additional source of light near the entrance
, plays back a voice message (“Wel-
come to xyz company …”) and establishes a video SIP connection to the reception-
ist's computer (or the guard on duty –
).
The softphone on the receptionist's computer
signals an inbound video phone
call from the camera at the entrance. The receptionist accepts the phone call and
talks to the visitor via the microphone and the speaker of the ExtIO.
The image displayed on the softphone, i.e. the live video stream from the MOBOTIX
camera allows for visually checking the visitor. The softphone's keys provide func-
tions for selecting certain image areas and for zooming the image (keys 1, 7: zoom
control, keys 2, 4, 6, 8: move image section, key 5: center image).
If the receptionist would like to open the door for the visitor, he/she activates the
door opener
using the softphone key 0, allowing the visitor to enter the build-
ing. If required, the receptionist can manually switch the additional lights using the
softphone keys
; key 3 switches the lights on and key 9 switches them off again.
