Symphony Services


Symphony server runs the following core Services. All Symphony Services are prefixed with an "AI".


AI InfoService

Web Server running Symphony's web service which receives all requests from the client.

AI NetSendHist

Responsible for historical video streaming and historical .JPEG creation.

AI Scheduler

Responsible for polling hardware alarm inputs, cleaning video, running reports and searches, synchronizes CPU and other processes on system.

AI Tracker X

The process that performs video analysis, saves video to disk, live video streaming. Each camera requires its own AI Tracker service.

Troubleshooting Tips:

  1. Symphony Requires the AI InfoService to be running properly. Normally connectivity issues between the client and server are caused by a resource conflict between another process using Port 50000, or a Firewall preventing Symphony and the AI InfoService from communicating properly.

  2. By default, Symphony installs a Microsoft SQL Server express database during the installation of Symphony Server. Make sure the SQL Server (AIMETIS) service is started.

Managing Symphony Services

Symphony services can be stopped and started individually. Services can be individually restarted directly from Symphony Client, or from Windows directly by using the Services Console.

From within Symphony

If you do not have direct access to the windows environment on the Symphony server, you can manage services remotely using Symphony Client.  


To manually stop and start individual services, from Symphony Client select Server > Services > Manage Services.


  1. Select which server to configure from the combo box above the Refresh button

  2. Select the services you want start or stop by clicking to the left of the service.

  3. Press the "Toggle" button.

  4. Press the "Refresh" button to see if the state of the server changed.


Warning: Changing service states can adversely affect your Symphony installation.



By default, the Symphony Services start on boot-up of the operating system. If you do not want Symphony Services to automatically start on system startup, uncheck the Automatically Start Symphony Services on system startup checkbox.
