Create an alarm for two people in a scene

1. In the Symphony server configuration interface, create a rule for people moving in the area where you only want two people.
2. In the Symphony client, open the Manual Configuration Editor and add a setting with the following information:
   • Type: Camera
   • ID: The ID of the camera that is tracking people.
   • Section: Camera
   • Key: OnlyAlarmWhenAlarmCount
   • Value: 2
3. In the Manual Configuration Editor, add a setting with the following information:
   • Type: Camera
   • ID: The ID of the camera that is tracking people.
   • Section: Camera
   • Key: OnlyAlarmPolicyId
   • Value: The ID of the rule you created in step 1.
4. Create a rule to alarm on a DIO trigger or reset event.
5. Use the DBUpdater or SQL Management Studio to modify the action for the rule you created in step 4 to have a trackerid the same as the ID of the camera that is tracking people.

   For example:

   dbupdater "update policy set XML='<action><alarm>1</alarm><record>1</record><resetcount><trackerid>ID of the camera that is tracking people</trackerid></resetcount></action>' where typ='action' and nm='NameOfActionFrom#4'"

   Note: Do not edit the rule that you created in step 4 in the Symphony server configuration interface because it will reset the changes.

6. Restart all trackers.
