The access control interface is used to connect a Niko Home Control installation on bus wiring to Niko analogue external video units in large residential buildings, such as apartments. Residents can now use their Niko Home Control touchscreen to communicate with visitors. This DIN-rail-mounted module needs to be configured via the Niko configuration software for access control. Use the Niko Home Control II programming software to set up the connection with your Niko Home Control installation.
