Intercom Configuration
The SilverBack V base unit can interface with either 4-wire or 2-wire party-line intercom systems using
the intercom/GPIO DB25 connector.
To configure the base unit intercom interface for 4-wire or 2-wire mode, navigate to the Base Unit
Settings menu and select Intercom, then either 4-wire or 2-wire. Both camera chains in the base unit
share the same interface type automatically.
Base Unit Menu > Base Unit Settings > Base Intercom Settings
For 2-wire intercom systems, it is recommended that an AutoNull be performed whenever any device is
physically added or removed from the 2-wire party line. To AutoNull any of the 2-wire intercom
channels, select the 2-wire AutoNull menu and click on the desired channel to be nulled. The AutoNull
process takes about 30 seconds to complete for each channel while a series of tones are transmitted on
that party line.
Base Unit Menu > Base Unit Settings > Base Intercom Settings > 2-Wire AutoNull
The Intercom settings may also be configured from the webpage dashboard accessed from the Base
Unit.
