P.iii)
By using the Audio Playback and audio recording* functions in the External Device Input settings,
it is possible to construct a monitoring system that issues audio alert using previously saved
sounds and captures video and audio* in response to external events. Photographed still images
and recorded audio files* are stored in the VB-C50i/VB-C50iR’s memory (

P.3-29).
Sample Application Combining a Speaker, Microphone and Door-opening Sensor
Each day between 5 pm. and 6 am., this monitoring system emits an audio alert whenever the
door opens and the VB-C50iR mounted on the ceiling records images shot at 1-second intervals
from 3 seconds before the door opens to 7 seconds after the door closes. It also records audio*
during that period. Install the devices below connected to the respective connectors on the Multi-
Terminal Module.

Installation Example
When the door opens and sensor B mounted on it separates from sensor A, an ON event occurs
at external device inputs IN

.
In response to this event, the VB-C50iR emits the stored audio alert from the speaker with amp,
shoots and records pictures of the doorway and records any audio* picked up by the microphone.
