To use input pins with Arecont units, the DisableInputPins advanced setting must be deactivated for the Arecont extension.
When using input pins with Arecont units in Security
Center, the Archiver sends a request to the
camera to know the state of the input pin. By default, input pins for Arecont units are
disabled in Security
Center.
If the unit is already added in Security
Center, then restart the unit.
