Symphony AC 'Drivers' are the primary means of communication and integration between the Symphony software and the subsystem it manages. Without the Driver, there is no management of the subsystem. The Driver, when it is correctly installed and working, runs as a Windows service on the server it's installed in.You can have multiple drivers managing the different subsystems. A Driver also can only be installed on the same server once. Drivers can reside on any server/workstation with Symphony AC installed.

  • Click to the left of the driver to expand the driver options.  Numerous driver types are available such as Access Control, Alarm System, DVR / NVR, Fire Panel, Telecommunications, Universal I/O and Video Matrix Switchers.  To add an Access Control driver click on the arrow to the left of Access Control Drivers and select the hardware platform installed in the field.  For example, Aero, Onity, or VertX.
