External I/O connections and wiring

General

The ABUS embedded recorders are equipped with
external interfaces for the control of alarm contacts, PTZ
cameras, keyboards and audio devices. The structure
level of the connections depends on the recorder model.
The larger the structure level of the recorder, the more
connections are normally present on the device.
Note
In your recorder's quickstart manual or at
http://www.abus.com, you will find an exact listing
of the external interfaces in the technical data.

Audio connections/2-way audio

The audio connections on the recorder are only used for
remote 2-way audio communication via a network
connection. This can take place via the web interface on
the recorder, via the ABUS CMS software or via the iDVR
Plus app. The system configuration for this purpose is as
follows:

Note
If the 2-way audio communication takes place via
a PC, you must ensure that a microphone and
loudspeaker are connected. In order to use the
web browser function, the ABUS recorder plug-in
must be installed.
