We had a client that had an old elan S6 system and needed some stuff looked at. When we were done she was mad at us because the lower gate camera didn't work anymore. She said that when someone pushed the call button it used to turn on the tv in the office and go to the video input and select the gate camera on the video switcher. We told her no way it ever did that, because the system wasn't capable of accepting trigger inputs, the gate wires to the house didn't have any trigger signals and the tv in the office was not part of the elan system control.

She threw a huge fit called her husband who came home immediately and asked us what was going on, she explained what the tv used to do and that it didn't work anymore....he started laughing and told her that would always turn on the tv and select the input with the tv remote when the gate button was pressed.
